Zero Trust Remote Access

Beyond traditional VPNs.

The Old Castle Model

Traditional security trusted anyone inside the network perimeter, like a castle with a moat.

Once past the VPN, a user could often reach many internal systems freely.

Why the Perimeter Failed

Cloud apps, remote work, and mobile devices erased the clear perimeter.

And if an attacker got inside, the implicit trust let them move freely. A new model was needed.
