CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Core Security Outflank Security Tooling
Mid-market and enterprise red teams will find Outflank Security Tooling essential for testing EDR bypass at scale; its steganography-based payload concealment and unpublished EDR evasion techniques let operators validate detection gaps that commodity toolkits can't expose. The continuous operator documentation and Cobalt Strike integration mean your team stays current as vendors patch, and on-premises deployment keeps artifacts off shared infrastructure. Skip this if your mandate is offensive security without a specific EDR validation requirement; Outflank assumes you're already comfortable with advanced post-exploitation and are hunting for the gaps most red teams never find.
Red team operators and penetration testers need DiskShadow because it's the only free tool that lets you weaponize VSS for both persistence and anti-forensics without touching commercial frameworks. The tool maps directly to NIST Respond functions by letting you test whether your detection stack catches VSS manipulation before an attacker actually uses it; most teams discover they can't. Skip this if your threat model assumes attackers won't touch Windows shadow copies, or if you're a blue team looking for detection content rather than offensive validation.
