AT&T SASE vs Zscaler Zero Trust: Side-by-Side Comparison (2026)

AT&T SASE

Mid-market and enterprise teams with distributed workforces already embedded in AT&T's network infrastructure will see immediate value from AT&T SASE because it eliminates the friction of bolting security onto existing connectivity; you're getting network and access control from the same vendor your pipes run through. The solution scores notably strong on identity and access control per NIST CSF 2.0, which means authentication decisions happen at wire speed without the latency tax you'd pay with a bolt-on SASE from a pure security vendor. Skip this if your organization runs on competing carrier networks or needs advanced threat detection and response; AT&T SASE prioritizes access enforcement over post-breach hunting.
