Executive Summary
A leading Indian financial services enterprise suffered a ₹24 crore breach triggered by a compromised remote access point. The incident exposed structural weaknesses in traditional firewall and VPN-based security models.
The organization transitioned to a Secure Access Service Edge (SASE) architecture, consolidating networking and security into a unified cloud-delivered platform. The result: 84% reduction in risk exposure, ₹3.2 crore annual cost savings, and near-elimination of remote access vulnerabilities.
Client Context
- Industry: Financial Services (BFSI)
- Scale: Multi-branch operations with distributed workforce and cloud-hosted applications
- Constraints:
- Legacy firewall + VPN architecture
- High regulatory compliance requirements (RBI, SEBI)
- Multiple security vendors with fragmented dashboards
- Rapid remote workforce expansion
Challenges
- Over-reliance on perimeter security
- VPN-based remote access vulnerabilities
- Lack of identity-centric access validation
- Alert fatigue due to multiple security tools
- High operational and licensing costs
- Delayed breach detection and containment
What We Implemented
Architecture
- SD-WAN for secure branch connectivity
- Secure Web Gateway (SWG)
- Cloud Access Security Broker (CASB)
- Firewall-as-a-Service (FWaaS)
- Zero Trust Network Access (ZTNA)
- Centralized policy and visibility dashboard
- Cloud-delivered security enforcement model
Execution Strategy
- Phase 1: Security assessment and cost analysis
- Phase 2: Pilot migration of remote users to ZTNA
- Phase 3: SD-WAN rollout across branches
- Phase 4: Centralized policy consolidation
- Phase 5: Gradual decommissioning of legacy VPN infrastructure
- Phase 6: Optimization and performance tuning
Results
- 84% measurable reduction in risk exposure
- ₹3.2 crore annual cost savings
- 22% reduction in licensing overhead
- Incident response time reduced from 6 hours to 11 minutes
- 94% improvement in alert accuracy
- Elimination of VPN-based breach vector
Lessons / Recommendations
- Perimeter-based security is insufficient in hybrid environments
- Identity must replace network location as the trust factor
- Vendor consolidation reduces cost and operational complexity
- Cloud-delivered security improves scalability and visibility
- SASE adoption should be strategic, not reactive
