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.
Startup and SMB security teams drowning in phishing reports will see immediate ROI from GhostGuard's browser-level detection; it stops credential theft before users even type a password. The tool covers both PR.AA (blocking fake login pages) and PR.DS (detecting payment flow manipulation), which means it actually prevents the attack rather than just logging it. Skip this if your workforce is mostly off-browser or you need endpoint-wide protection beyond Chrome and Safari; GhostGuard is deliberately narrow in scope, which is precisely why it works.
