CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Mid-market and enterprise security teams replacing on-premise web gateways will find Zscaler Internet Access worth the migration effort because it actually inspects encrypted traffic at scale without killing performance, something most cloud SSE platforms struggle with. The platform covers DE.CM and DE.AE through continuous monitoring and AI-powered threat detection across DNS, URLs, and files, giving you visibility into what your old gateway missed. Skip this if your organization needs deep integration with on-prem infrastructure or runs custom legacy applications that depend on transparent proxy architecture; Zscaler's cloud-first design optimizes for modern SaaS and internet access, not hybrid networks.
