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 that want employees to actually report phishing should pick PhishingBox Security Inbox; its integration with internal phishing simulations means reported emails feed directly into your training data, closing the loop between threat detection and behavior change. The tool scores across DE.AE, PR.AT, and RS.MI in NIST CSF 2.0, with particularly strong coverage in adverse event analysis and incident mitigation through real-time threat removal. Skip this if you need a standalone detection engine to replace your email gateway; PhishingBox is a reporter and remediation layer that assumes you already have upstream filtering in place.
