Zero Trust

Zero trust network access (ZTNA) replaces VPNs with identity-based application access. Micro-segmentation limits network lateral movement. Continuous authentication verifies users throughout sessions (not just at login). Policy engines enforce least-privilege access decisions in real time. Security service edge (SSE) delivers zero trust from the cloud.

ZTNA provides remote workers with secure application access without VPN. Micro-segmentation prevents ransomware from spreading across network segments. Continuous authentication detects session hijacking. Policy engines automatically enforce access rules based on user, device, and context.

The zero trust security market exceeded $30 billion in 2025 as the architecture becomes the default enterprise security model.
