Zero Trust Network Access (ZTNA): Decommissioning Legacy Corporate VPNs
Replacing vulnerable perimeter VPN concentrators with application-specific identity proxies that enforce continuous least privilege.
The Fundamental Flaw of Legacy Corporate VPNs
Traditional VPNs operate on perimeter trust: once an employee authenticates via VPN, they are granted broad network-layer (IP/subnet) access to hundreds of internal servers and services, enabling rapid lateral movement for compromised endpoints.
How ZTNA Enforces Micro-Perimeters
Zero Trust Network Access (ZTNA) establishes outbound-only identity connections. Users authenticate directly to a cloud identity broker and are granted access exclusively to authorized applications (e.g., Jira or an internal ERP) without ever accessing the underlying network.
Eliminating Public VPN Vulnerabilities
ZTNA eliminates public-facing listening ports on your corporate firewall, making your internal infrastructure completely invisible to internet-wide reconnaissance scanners.
