Case Study|Cybersecurity
Caystard implemented a zero-trust security architecture for a national insurance provider, cutting unauthorized access incidents by 90% and achieving full regulatory compliance.
Following an industry-wide rise in ransomware attacks targeting insurers, a national insurance provider engaged Caystard to overhaul its cybersecurity posture from a traditional perimeter-based model to a modern zero-trust architecture.
90% reduction in unauthorized access incidents
100% pass rate on next compliance audit
24/7 SOC monitoring coverage established
6-month full deployment timeline
The provider's existing security model relied heavily on perimeter firewalls and VPNs, leaving internal systems vulnerable once any single credential was compromised. Remote and hybrid work had expanded the attack surface significantly, and the company faced growing pressure to meet stricter state and federal data protection regulations.
Caystard designed and deployed a zero-trust security framework built on continuous identity verification, micro-segmentation of internal networks, and least-privilege access controls. Endpoint detection and response (EDR) tooling was rolled out company-wide alongside a security operations center (SOC) upgrade for 24/7 threat monitoring.
The engagement started with a comprehensive security audit and risk assessment across the insurer's network, identifying critical gaps in identity management and lateral movement protection. Caystard's cybersecurity team then implemented multi-factor authentication tied to continuous risk-based verification, replacing static, one-time login checks.
Network micro-segmentation was introduced to contain any potential breach to a small, isolated zone rather than allowing lateral movement across the organization. Access policies were rebuilt around least-privilege principles, with automated reviews to catch privilege creep over time.
A modernized SOC, staffed and tooled for continuous monitoring, was stood up to detect and respond to threats in real time rather than relying on periodic audits. Employee security training was refreshed to reflect the new access model. Within six months of full deployment, the insurer saw a dramatic drop in unauthorized access attempts and passed its next regulatory compliance audit without findings.
