The Challenge

The banking group faced credential-based intrusions across branch networks and legacy VPNs, requiring identity-first access controls and continuous verification.

Key Issues:

  • Stolen credential reuse
  • Flat internal network segments
  • Overprivileged VPN access
  • Weak multi-factor enrollment coverage

The Solution

We rolled out zero trust access with phased identity verification, device posture checks, and least-privilege policy enforcement.

Key Actions:

  • Identity-first policy enforcement
  • Device posture checks before every session
  • Micro-segmentation of core banking zones
  • Continuous session verification
Trust is no longer a network perimeter. Every request, device, and identity earns access on its own merits, verified again at the moment it matters.

Compliance & Risk Management

Regulated institutions must prove control effectiveness continuously, not once a year. Our zero trust programme maps every access decision to auditable policy, giving compliance teams evidence on demand while security teams retain real-time visibility across all branches.

  • Regulated institutions must prove control effectiveness continuously, not once a year.
  • Access Governance & Review – Least-privilege enforcement across every banking system.
  • Continuous Control Monitoring – Live evidence for PCI DSS and internal audit teams.
  • Privileged Session Management – Recorded, time-bound access for administrator accounts.
