SASE vs. Legacy VPN: What Actually Changes

Legacy VPNs were built for a perimeter that no longer exists. They backhaul traffic to a data center, add latency, and grant broad network access once a user is in.

SASE converges networking and security into a cloud-delivered edge: identity-aware access, inline inspection, and policy that follows the user instead of the office.

The migration is rarely all-at-once. We typically start with the riskiest access paths — third parties and privileged admins — then expand as confidence grows.
