Zero Trust Network Architecture Implementation

Project Overview

A mid-sized financial services firm was operating on a traditional perimeter-based security model that left them vulnerable to insider threats and lateral movement attacks. With increasing remote work and cloud adoption, their legacy security approach was no longer sufficient to protect sensitive financial data and customer information.

The Challenge

Legacy Security Model: Traditional perimeter-based security with implicit trust vulnerabilities
Insider Threats: Increasing risks from lateral movement attacks and insider threats
Hybrid Cloud Environment: Complex multi-cloud infrastructure requiring unified security
Regulatory Compliance: Strict requirements for SOX and PCI DSS compliance
User Experience: Need for seamless access during security transformation
