Replacing legacy VPN configurations with cryptographically signed tunnels and dynamic VLAN micro-segmentations.
Remote employees accessed critical corporate directories and customer databases using a shared single-tunnel legacy VPN. This layout generated significant security risks: compromising a single user credential exposed the entire private network to lateral attack movements, due to a complete lack of internal segmentation.
Since protecting client repository access is a primary security requirement, transitioning away from the "trusted local network" concept was essential.
Norexter Solutions designed and implemented a modern Zero Trust framework. We replaced the centralized legacy VPN with dynamic, cryptographically signed WireGuard tunnels. We integrated these tunnels with an Identity Provider (IdP) via OAuth2/OIDC for dynamic authorization and enforced local device posture analysis prior to connection.
All connection policies are evaluated continuously, allowing real-time session revocations if client posture compliance changes.
Employees are granted access only after passing Multi-Factor Authentication (MFA) and device health compliance audits. Connections are restricted to designated resources needed for the employee's role (least privilege access), using strict micro-segmentation configured on switch VLANs and central OPNsense firewalls.
All remote database interactions are encrypted, logged, and audited. Automation cut credential onboarding delays while network vulnerability surface area dropped.
