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.
SMB and mid-market teams deploying remote workforces need NAN SASE because it bundles firewall, DNS protection, DLP, and zero trust network access without forcing you to manage separate vendors. Built on Fortinet's FortiGate architecture, it covers four NIST CSF 2.0 functions including continuous monitoring and data security, meaning you get detection and prevention in one managed service rather than cobbling together point tools. Skip this if your organization runs hybrid cloud infrastructure where you need deep CSPM or CIEM; NAN prioritizes perimeter and access control, not cloud-native workload visibility.
