What is Sentinel Cloud Firewall as a Service (FaaS)?
India's enterprise-grade network security platform — delivered entirely from the cloud, no hardware, no complexity.
Sentinel is Connect Quest's fully managed Cloud Firewall as a Service (FaaS) and Zero Trust Network Security Platform — a next-generation network security solution comparable to Palo Alto Networks NGFW and Cloudflare Zero Trust, built specifically for the Indian business market. Whether you're protecting a 50-person office in Assam or a 500-seat contact centre in Mumbai, Sentinel provides enterprise-grade protection without the capital expenditure and operational complexity of on-premise hardware appliances.
Unlike legacy hardware firewalls that sit on your network perimeter and require manual rule updates, Sentinel is continuously managed by Connect Quest's security engineers. Our team monitors your traffic around the clock, pushes global threat intelligence updates in real time, and responds to incidents on your behalf — so your IT team can focus on business growth rather than security firefighting. Sentinel combines the capabilities of stateful packet inspection, deep packet inspection (DPI), intrusion detection and prevention (IDS/IPS), Layer 7 application-aware filtering, and Zero Trust Network Access (ZTNA) in a single managed cloud platform.
The platform is purpose-built for businesses that rely on VoIP calling, CRM systems, and remote team connectivity — the exact workloads most vulnerable to disruption from cyberattacks. Sentinel's intelligent QoS rules prioritise VoIP packets and CRM traffic, ensuring your operations run smoothly even during an active threat event. With three tiers — Sentinel Edge, Sentinel Guard, and Sentinel SOC — there is a plan for every risk profile, team size, and compliance requirement.
The Modern Cyber Threat Landscape Facing Indian Businesses
India is now the third most targeted country for cyberattacks globally. Every business with an internet-connected network — from a 10-person BPO in Guwahati to a 500-seat fintech platform in Mumbai — faces an expanding and accelerating threat environment that hardware firewalls and manual IT teams cannot adequately address alone.
Ransomware Attacks
Ransomware gangs increasingly target Indian SMEs and BPOs, knowing that smaller organisations lack the security infrastructure to detect and stop lateral movement through their networks. A single successful ransomware infection can encrypt an entire business's lead database, call recordings, and operational systems — causing days or weeks of downtime. Sentinel's IDS/IPS and threat intelligence feeds detect ransomware command-and-control traffic patterns and block them before encryption begins.
DDoS Botnets
Distributed Denial of Service attacks using global botnet infrastructure can flood a business's internet connection with millions of packets per second — rendering VoIP calls unusable, CRM systems inaccessible, and customer-facing services offline. Call centres and BPOs are particularly high-value targets because disrupting their operations has direct, measurable revenue impact. Sentinel's DDoS scrubbing technology detects and absorbs volumetric attacks before they reach your network infrastructure.
Credential Stuffing
Attackers use databases of leaked username/password combinations to systematically attempt logins to CRM dashboards, admin portals, and VoIP management systems. A successful credential stuffing attack against an OpsBridge CRM login or EchoConnect admin portal can give attackers access to your entire lead database, call recordings, and customer data. Sentinel's bot mitigation and rate limiting blocks automated credential stuffing attempts at the network layer — before they reach your application login pages.
Phishing Infrastructure
Modern phishing campaigns use dynamically generated domains to bypass traditional blocklists. When employees in your call centre or sales team click phishing links, their devices can be compromised — providing attackers with a foothold inside your network. Sentinel's real-time DNS filtering, threat intelligence feeds with freshly categorised malicious domains, and network-level phishing protection intercept these connections before credential theft or malware installation occurs.
API Abuse & Injection Attacks
As businesses integrate CRM platforms, telephony APIs, and cloud services, the attack surface expands significantly. API endpoints can be targeted with automated abuse — from data scraping attacks that extract entire CRM databases to SQL injection attempts targeting customer records. Sentinel's Web Application Firewall (WAF) and API security layer inspect HTTP/S traffic at Layer 7, detecting and blocking injection attempts, parameter manipulation, and automated API abuse before it reaches your application servers.
VoIP Toll Fraud & SIP Attacks
SIP brute-force attacks, toll fraud, and VoIP eavesdropping are among the most financially damaging threats specifically targeting call centres and businesses using cloud telephony. Attackers compromise poorly secured SIP infrastructure to make thousands of international calls fraudulently — generating bills of lakhs within hours. Sentinel's SIP-aware deep packet inspection detects abnormal call patterns, blocks unauthorised SIP registration attempts, and quarantines suspected toll fraud traffic in real time.
Every one of these threats is actively targeting Indian businesses today. Sentinel was built to stop all of them.
Sentinel Enterprise Cloud Security Architecture
Sentinel is built on a multi-layer cloud security architecture that inspects, filters, and protects traffic at every stage of its journey — from your users to the internet and back — without introducing latency or operational complexity.
Global Threat Intelligence
Continuous feeds from threat intelligence networks update Sentinel's blocking rules in real time — catching zero-day threats and newly registered malicious infrastructure
Distributed Firewall Nodes
Sentinel runs across multiple cloud nodes in Indian data centres — ensuring redundancy, geographic coverage, and low latency for domestic traffic routing
Multi-Layer Traffic Inspection
Traffic passes through stateful packet inspection (L3/L4), deep packet inspection (L7), IDS/IPS signature matching, and application-aware policy enforcement in sequence
Cloud Routing Fabric
Policy-based routing, multi-WAN failover, and VLAN segmentation are managed at the cloud layer — enabling branch offices and remote teams to operate on unified security policies
Zero Trust Access Layer
Identity-based access control and device posture validation enforced at the network edge — no user or device is trusted by default, regardless of network location
Real-Time Analytics Engine
Every packet, connection, and security event is processed through the analytics engine — feeding live threat dashboards, SIEM integrations, and forensic investigation queues
Full Enterprise Security Capability Stack
Sentinel combines the capabilities of pfSense, Palo Alto NGFW, and Cloudflare Zero Trust in a single managed cloud security platform — without the complexity or cost of deploying each separately.

Sentinel Zero Trust Network Access Platform
The traditional security model — trusting everything inside the network perimeter — is fundamentally broken in the era of remote work, cloud applications, and mobile devices. Zero Trust replaces perimeter-based trust with continuous verification: no user, device, or application is trusted by default, regardless of whether they are inside or outside the corporate network.
Sentinel implements a full Zero Trust Network Access (ZTNA) architecture — giving Indian enterprises the same security posture that Fortune 500 companies use to protect their most sensitive systems, at a fraction of the cost of deploying standalone ZTNA platforms.
Identity-Based Access Verification
Every access request — whether from an employee in the office or a remote agent in Imphal — is authenticated against identity policies before any network connection is established. Sentinel verifies who is requesting access, not just where the request originates from, eliminating the risk of compromised network segments granting broad access.
Device Posture Validation
Before allowing a device to access business applications, Sentinel validates its security posture — checking that the device meets defined security standards (OS patching level, endpoint protection status, encryption status). Unmanaged or non-compliant devices are blocked from accessing sensitive applications even if the user credentials are valid.
Application-Level Access Control
Instead of granting VPN access to the entire network, Sentinel's ZTNA grants access only to specific approved applications — CRM systems, VoIP platforms, internal admin portals. Agents can access OpsBridge and EchoConnect; they cannot access financial systems or infrastructure management tools. Granular, application-level access control dramatically reduces the blast radius of any credential compromise.
Continuous Session Monitoring
Zero Trust is not a one-time check — it is continuous. Sentinel monitors active sessions for anomalous behaviour throughout their duration. If a verified user suddenly starts accessing unusual resources, downloading abnormal data volumes, or connecting from a new geographic location, Sentinel's behavioural analytics engine flags and can terminate the session automatically.
How Sentinel Cloud Firewall Works
From sign-up to fully protected enterprise network in four simple steps.
Choose Your Sentinel Plan
Select Edge, Guard, or SOC based on your organisation size, risk profile, and compliance needs. Our pre-sales team is happy to assist with a free network security assessment.
Cloud Provisioning & Configuration
Our security engineers deploy and configure your cloud firewall environment, define baseline security rules, set up VoIP/CRM traffic policies, and configure VPN gateways — all tailored to your business architecture.
Traffic Routing & Policy Activation
Your network traffic is routed through the Sentinel cloud layer. Malicious traffic is blocked in real time while legitimate VoIP, CRM, and business traffic flows without interruption through the QoS-prioritised routing fabric.
Continuous Monitoring & Reporting
Our team monitors your firewall 24/7, responds to incidents, pushes threat intelligence updates, and delivers regular security reports — keeping you protected as threats evolve and your network grows.
24/7 Security Operations Centre — Enterprise Threat Response
Sentinel SOC provides Indian enterprises with a dedicated Security Operations Centre — the same level of security coverage that Fortune 500 companies maintain with teams of in-house security analysts, delivered as a fully managed monthly service.
24/7 Live Monitoring
Security analysts monitor your network traffic, firewall events, and threat alerts around the clock — including nights, weekends, and public holidays. Attacks do not respect business hours; neither does Sentinel SOC.
Active Threat Response
When a security event is detected, Sentinel SOC analysts do not just alert you — they act. Malicious IPs are blocked, infected sessions are terminated, and firewall rules are updated in real time to contain the threat while you are notified with a full incident brief.
SIEM Integration
Sentinel SOC feeds your preferred SIEM platform with correlated security events — enabling your internal security team to have full visibility into Sentinel's detection and response activity within your existing security infrastructure and compliance workflows.
Forensic Investigation
When a security incident occurs, Sentinel SOC conducts full forensic analysis — tracing the attack chain, identifying the initial compromise vector, quantifying data exposure, and delivering a root-cause report with remediation recommendations to prevent recurrence.
Who Needs Sentinel Cloud Firewall?
Built for every industry where network security is non-negotiable.
Call Centres & BPOs
VoIP call quality is mission-critical in contact centres. Sentinel's traffic prioritisation ensures zero-lag calls while blocking toll fraud, SIP brute-force attacks, and bandwidth abuse from bad actors targeting your telephony infrastructure.
BFSI — Banks & Fintech
Financial institutions handling sensitive customer data need Layer 7 protection, IDS/IPS, and compliance reporting (PCI-DSS, RBI guidelines). Sentinel Guard and SOC cover all requirements for regulated financial operations.
Healthcare & Hospitals
Patient data must be protected under strict regulatory standards. Sentinel SOC provides round-the-clock monitoring, breach detection, and audit-ready compliance reports for healthcare organisations managing sensitive medical records.
E-Commerce & Retail
Protect payment gateways, customer databases, and admin portals from SQL injection, credential stuffing, and DDoS attacks — especially during peak sale seasons like Diwali, when attack volumes spike dramatically.
Remote & Hybrid Workforces
Secure employees working from home or across multiple locations using cloud-enforced Zero Trust access policies — no physical VPN appliance required at each site, no per-device software to manage.
IT MSPs & Hosting Providers
Managed service providers can deploy Sentinel as a white-label security layer for their clients, adding a high-margin recurring revenue stream with zero hardware overhead — protecting client networks under a managed security service model.
Industries That Need Sentinel Cloud Firewall
Every sector in India faces a unique combination of cybersecurity threats and regulatory obligations. Here is how Sentinel's enterprise cloud firewall platform addresses the specific security requirements of the industries most in need of managed network protection.
Call Centres
Call centres operate VoIP infrastructure that is among the most actively targeted systems in India — subject to SIP brute-force attacks, toll fraud, and DDoS floods designed to disrupt operations. Sentinel's SIP-aware deep packet inspection, VoIP QoS prioritisation, and bot mitigation technology protect call centre telephony infrastructure while ensuring agent call quality remains crystal clear under any network condition. For call centres using both OpsBridge CRM and EchoConnect cloud telephony, Sentinel provides the security layer that protects both systems simultaneously.
BPO Companies
BPO companies manage client data under strict confidentiality obligations — a data breach involving client lead databases or recorded calls can result in contract termination and significant liability. Sentinel's role-based network segmentation ensures each client's data environment is isolated from others, while IDS/IPS monitoring detects lateral movement attempts that could spread from one client's systems to another. The Sentinel SOC tier's SIEM integration enables BPOs to provide clients with audit-ready security event logs as part of SLA reporting.
Fintech Platforms
Fintech companies processing payments and managing financial data are subject to RBI guidelines and PCI-DSS compliance — both of which require demonstrable network security controls, access logging, and incident response capabilities. Sentinel Guard's Layer 7 application firewall protects API endpoints from injection attacks and parameter manipulation. Sentinel SOC's compliance reporting framework generates the audit-ready documentation that fintech platforms need for regulatory submissions and security audits. The Web Application Firewall (WAF) specifically protects payment gateway endpoints from the SQL injection and API abuse attacks that target financial infrastructure.
Healthcare Providers
Hospitals, clinics, and health-tech platforms manage patient data that is among the most sensitive information in any database — carrying strict obligations under India's IT Act and international standards. A breach of patient records causes irreparable reputational damage and significant legal liability. Sentinel SOC provides continuous monitoring of healthcare network environments, detecting unauthorized access to patient databases, anomalous data export patterns, and ransomware behaviour before it can encrypt medical records. The forensic investigation capability enables healthcare organizations to respond to incidents with the evidence required for regulatory notification procedures.
Insurance Companies
Insurance companies manage agent networks, customer policy databases, and high-value claim records across distributed offices and field teams — an attack surface that requires unified security policy enforcement regardless of location. Sentinel's Zero Trust Network Access ensures that insurance agents working from remote locations access only the specific CRM and policy management systems their role permits — preventing lateral movement within the network if any agent device is compromised. Geo-IP blocking at the Sentinel Guard tier protects insurance platform login pages from international credential stuffing attacks targeting policy databases.
E-Commerce Platforms
E-commerce platforms process payment transactions and store customer payment credentials — making them prime targets for card skimming attacks, SQL injection, and credential theft. Sentinel's Web Application Firewall inspects every HTTP/S request to your storefront and checkout flow, blocking injection attempts and parameter manipulation in real time. Rate limiting protects against inventory manipulation attacks and automated price scraping. DDoS protection ensures your platform stays online during peak sale events when competitors may sponsor volumetric attacks. The bot mitigation layer filters automated checkout bots that reduce stock availability for genuine customers.
Education Platforms
EdTech platforms and educational institutions managing student admission data, learning records, and fee payment systems face growing cybersecurity threats as digital adoption in Indian education accelerates. Credential stuffing attacks targeting student and faculty login portals are increasingly common. Sentinel's bot mitigation and rate limiting blocks automated login abuse, while the application-aware firewall protects learning management systems from unauthorized access. For institutions using cloud telephony for student counselling calls, Sentinel's VoIP protection ensures call quality and prevents SIP-based eavesdropping of sensitive admission conversations.
Real Estate Firms
Real estate companies managing high-value property transaction databases and client financial profiles are attractive targets for corporate espionage and data theft. A competitor or attacker gaining access to a real estate firm's lead database — containing property interests, budgets, and contact information — represents a direct business threat. Sentinel's network segmentation and access control ensures that CRM platforms are accessible only from authorized devices and locations. For real estate firms using distributed agent networks across cities, Sentinel's Zero Trust access model ensures security policy consistency regardless of where agents connect from.
Digital Marketing Agencies
Digital marketing agencies managing ad accounts, client CRM data, and campaign analytics platforms across multiple client environments face both credential theft risks and client data confidentiality obligations. A single compromised login to an agency's Google Ads or Meta Business account can drain client budgets within hours. Sentinel's bot mitigation, rate limiting on authentication endpoints, and real-time threat intelligence protect the web-based platforms agencies rely on daily. The network segmentation capability ensures separation between client environments — critical for agencies managing multiple brands in the same office network.
IT Service Providers
IT managed service providers are among the highest-value targets for sophisticated threat actors — because compromising an MSP's infrastructure provides access to all of their clients' networks simultaneously. Sentinel's Zero Trust architecture specifically addresses this supply chain risk: even if one client environment is compromised, lateral movement to other client environments is blocked by Sentinel's network segmentation and identity-based access controls. IT MSPs can also white-label Sentinel as a managed security offering to their clients, creating a high-margin recurring revenue stream from a service they are already deploying for their own infrastructure.

Cloud Firewall for North East India — Connect Quest's Home Region
Connect Quest was founded in North East India — and Sentinel is built with the specific cybersecurity challenges of the region's growing business community in mind. From the BPO sector in Guwahati to the emerging fintech ecosystem in Shillong and the distributed enterprises across Manipur, Mizoram, Tripura, Nagaland, Arunachal Pradesh, and Sikkim — North East India's businesses deserve enterprise-grade cybersecurity infrastructure.
As North East India's most advanced cloud infrastructure and cybersecurity provider, Connect Quest delivers enterprise firewall capabilities to businesses across the region that have historically been underserved by large cybersecurity vendors focused only on metro markets. Sentinel's cloud-native architecture means businesses in any city in the region can deploy enterprise-grade network security without shipping hardware or engaging expensive on-site consultants.
Talk to a Regional Security ExpertAssam's growing BPO and telecalling sector in Guwahati relies heavily on VoIP infrastructure — making it a target for SIP attacks and toll fraud. Sentinel Edge and Guard protect call centre networks, CRM platforms, and employee remote access with enterprise-grade security at a price point accessible to Assam's SME community. As Connect Quest's home state, Assam businesses benefit from direct local support and the fastest deployment times.
Shillong's emerging technology and education sector faces cybersecurity challenges typical of rapidly digitising mid-sized cities — credential stuffing against business portals, phishing campaigns targeting employees, and DDoS threats to public-facing platforms. Sentinel's cloud-native architecture deploys without physical infrastructure, making it ideal for Meghalaya businesses that cannot justify on-premise hardware investments but need professional network security.
Healthcare facilities, government service portals, and growing commercial enterprises in Imphal face increasing cybersecurity threats as digital adoption accelerates across Manipur. Sentinel's managed firewall service provides continuous protection without requiring local IT security expertise — Connect Quest's remote security team handles monitoring, incident response, and policy management on behalf of Manipur businesses from the centralised operations centre.
Agartala's SME sector and emerging digital businesses use Sentinel to deploy professional network security as they transition from manual operations to cloud-based tools. The ability to deploy enterprise-grade cloud firewall protection without shipping hardware to Tripura — and without engaging expensive on-site security consultants — makes Sentinel the practical choice for Agartala businesses beginning their cybersecurity journey.
Businesses in Aizawl operating across Mizoram's geographically distributed terrain particularly benefit from Sentinel's cloud-based architecture — field staff connecting from remote locations receive the same network security protection as office-based employees, enforced at the cloud layer without per-device software. Sentinel's remote team support capability is purpose-built for the distributed workforce models common in Mizoram's growing commercial sector.
Nagaland's business community is increasingly targeted by the same automated cyberthreat infrastructure that attacks enterprises across India — bots, credential stuffers, and DDoS tools do not discriminate by city size or geography. Sentinel provides Kohima businesses with the same threat intelligence feeds and automated blocking that protects enterprises in Mumbai and Bangalore, ensuring North East India's businesses are not left as soft targets due to perceived geographic distance from cyber threat ecosystems.
Enterprises in Itanagar managing digital operations across Arunachal Pradesh's vast geography use Sentinel's Zero Trust access model to ensure that employees connecting from different districts access only the specific applications their role requires — eliminating the security risks associated with broad VPN access grants across distributed workforces operating in challenging network environments.
Gangtok's hospitality, education, and healthcare sectors are increasingly digitising their operations — moving CRM, billing, and customer management to cloud platforms that require secure internet access policies. Sentinel Edge provides the entry-level managed firewall protection that Sikkim's growing SME community needs to protect cloud-hosted business platforms from the automated attacks that target any internet-accessible system regardless of business size or location.
What is Cloud Firewall as a Service (FaaS)?
Everything Indian businesses need to understand about modern cloud firewall technology — how it works, why hardware firewalls are becoming obsolete, and how FaaS delivers enterprise security at a fraction of the traditional cost.
How Cloud Firewalls Work
A Cloud Firewall as a Service replaces the traditional hardware appliance at your network perimeter with a software-defined security layer hosted in the cloud. Instead of your internet traffic flowing directly from your ISP to your office network — where it is filtered by a physical device — traffic is routed through the cloud firewall platform first.
Within the cloud firewall's processing layer, traffic is subjected to multiple inspection processes: stateful packet inspection checks that connection states are legitimate; deep packet inspection examines the actual content of packets for malware, exploit patterns, and protocol abuse; intrusion detection signatures compare traffic patterns against known attack methods; and application-aware filtering applies Layer 7 policies that understand which applications are sending which traffic. Only traffic that passes all inspection layers reaches your users and systems.
The entire process adds only milliseconds of latency — Sentinel's India-hosted nodes add just 2–5ms for domestic traffic — while providing a security inspection depth that would require multiple racks of hardware equipment to replicate on-premise at comparable throughput capacity.
Why Hardware Firewalls Are Becoming Obsolete
Hardware firewalls were designed for a world where all users worked from one office, all applications ran on local servers, and the security perimeter was clearly defined by the physical office boundary. That world no longer exists for most Indian businesses.
When half your agents work from home in different cities, your CRM is hosted in a cloud data centre, your telephony is delivered via a cloud VoIP platform, and your applications are SaaS products accessed over the internet — a hardware firewall at your office perimeter protects almost nothing meaningful. Remote workers bypass it entirely. Cloud applications communicate directly with data centres that have no relationship to your office network. The perimeter has dissolved.
Cloud Firewall as a Service addresses this architectural reality by enforcing security policies at the cloud layer — where all traffic, regardless of origin (office, home, field), converges before reaching your applications. This is why Cloudflare, Palo Alto Networks, and Zscaler have all pivoted to cloud-delivered security models — and why Sentinel delivers the same architectural approach at Indian market pricing.
Key Benefits of Cloud Firewall for Modern Indian Businesses
Eliminates Hardware Procurement Cycles
Traditional hardware firewall deployment requires procurement (2–4 weeks), rack installation, configuration by a certified engineer, and annual maintenance contracts. Sentinel deploys in 24–48 hours, requires no physical installation, and is maintained by Connect Quest's engineers as part of the monthly subscription.
Continuous Threat Intelligence Updates
Hardware firewalls require manual firmware updates and signature file downloads — which in practice means most SMEs are running outdated threat definitions. Sentinel's cloud architecture enables real-time propagation of threat intelligence updates across all nodes simultaneously — new attack signatures are active within minutes of detection, not days.
Instant Scalability Without Hardware Constraints
A hardware firewall has a fixed maximum throughput capacity. When your team grows beyond that capacity, you replace the hardware — another CapEx cycle. Sentinel's cloud architecture scales compute resources automatically with your traffic volume — there is no hardware ceiling to hit, no equipment to replace when you grow from 50 to 500 users.
Consistent Protection for Remote Teams
Because cloud firewall policies are enforced at the cloud layer rather than the office perimeter, remote employees receive identical protection to office-based ones. An agent in Imphal connecting to OpsBridge or EchoConnect from home receives the same threat detection, VoIP prioritisation, and access control enforcement as an agent sitting in the Guwahati office.
How Zero Trust Security Protects Modern Businesses
Zero Trust is not a product — it is a security architecture philosophy. Understanding its principles helps Indian businesses make better decisions about how to protect their distributed workforce, cloud applications, and sensitive data from increasingly sophisticated threats.
Identity-Based Access: "Never Trust, Always Verify"
The foundational Zero Trust principle is that no user or device should be trusted by default — regardless of whether they are inside the corporate network or outside it. Every access request must be authenticated and authorised before it is granted. This model eliminates the catastrophic blast radius of VPN compromises, where gaining access to the network previously granted access to everything on it. In a Zero Trust model, even if an attacker obtains valid credentials, they can only access the specific applications that identity is authorised to reach.
Application Segmentation: Isolate Everything
Traditional network security models grant access to network segments — a user connected to the VPN can reach everything on the office network. Zero Trust replaces this with application-level segmentation: users are granted access to specific applications (CRM, VoIP platform, HR system, payment portal), not to the network fabric those applications run on. This segmentation ensures that compromising one application does not automatically expose all other applications to the same attacker — limiting the damage of any successful credential theft or application vulnerability exploitation.
Continuous Verification: Security Beyond Login
Zero Trust security does not end at the login screen. Continuous session monitoring validates that authenticated users are behaving consistently with their normal patterns throughout the entire session. If a verified user suddenly accesses systems outside their normal usage patterns, downloads unusual data volumes, or connects from a new location mid-session, the Zero Trust system flags and can automatically terminate that session — catching account takeovers that occur after legitimate initial authentication. Sentinel's behavioural analytics engine implements this continuous verification model, adding a dynamic layer of protection that static firewall rules cannot provide.
