CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Mid-market and enterprise security teams drowning in phishing false positives will find real value in Egress Defend's behavioral AI that learns individual user patterns instead of firing on every suspicious link. The platform's time-of-click verification and one-click remediation directly address the gap between detection and human response, cutting remediation friction that legacy tools create. Skip this if your organization needs a unified email security stack that also handles data loss prevention; Egress Defend stays focused on phishing and leaves DLP to other tools.
