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 investigating phishing and malware at mid-market and enterprise scale should choose Splunk Attack Analyzer for its automated attack chain execution, which eliminates the manual reverse-engineering work that burns analyst hours. The platform covers both DE.AE and RS.AN functions under NIST CSF 2.0, meaning you get threat characterization and incident analysis in one workflow, plus native integration with Splunk SOAR for moving from investigation to response without context switching. The main tradeoff: this is a cloud-only tool optimized for high-volume triage, not for teams needing on-premises malware analysis or deep forensic control over sandboxed execution environments.
