CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams managing Office 365 tenants without dedicated phishing forensics tooling should start with Phishing Intelligence Engine; it extracts signal from Message Trace logs that most teams leave unanalyzed, turning native telemetry into actionable detection patterns at zero cost. The 180 GitHub stars and active-defense framework design show this sees real deployment in mature shops, not abandoned proof-of-concept code. Skip this if your organization already runs a dedicated phishing sandbox or has analyst bandwidth to manually hunt; PIE solves the gap between "we have logs" and "we can act on them.
Startup and SMB security teams protecting Microsoft 365 will benefit most from Attic M365 FREE because it stops AiTM phishing attacks that bypass MFA, the attack class traditional email filters miss entirely. The tool deploys in five minutes with no payment required, making it immediately useful for resource-constrained teams, and its real-time detection of fake login pages covers both NIST PR.AA and DE.CM functions simultaneously. Skip this if your organization needs protection beyond Microsoft 365 or runs a heterogeneous SaaS stack; Attic is deliberately focused on one platform and one threat vector.
