CISA maps SASE to TIC 3.0 zero-trust transition

Inside Cybersecurity reports that the Cybersecurity and Infrastructure Security Agency has released June 24 guidance for using Secure Access Service Edge (SASE) solutions in Trusted Internet Connections (TIC) 3.0 migrations. The useful part is the architecture concession: TIC 3.0 can be satisfied by controls that sit near users, devices and applications, provided agencies maintain the visibility CISA expects. That matters because TIC 2.0 grew out of a centralized perimeter model. SASE asks agencies to enforce access through policy decisions that consider identity, device posture, application context, data sensitivity and network conditions instead of treating the network boundary as the main trust event.

For implementation teams, the document reads less like a procurement instruction than a translation layer between the TIC program and zero trust architecture work. It gives data-flow security patterns and describes complementary technologies for securing users, devices, networks and applications. The hard work remains local: mapping existing mission systems, user groups and access patterns before placing distributed controls. CISA’s message is flexible, but bounded. Agencies can move away from routing traffic through classic TIC access points only if they can preserve situational awareness for both the agency and CISA.
