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.
Security teams running manual phishing triage will appreciate BuckleGripper's speed; it automates the tedious work of visiting suspicious URLs, capturing evidence, and extracting payloads that analysts normally do by hand. The free pricing and 99 GitHub stars suggest real adoption among smaller teams without budget for commercial sandboxes. Skip this if you need integration with your SOAR or ticketing system; BuckleGripper is a standalone reconnaissance tool, not a workflow automation platform.
