CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams that need to move fast on active incidents will find AISI DFIR's managed service model cuts through the hiring shortage for in-house forensics expertise. The Scout and Hunter tools automate evidence collection and persistence removal directly on affected systems, compressing response timelines that would otherwise stretch weeks. The caveat: this is a managed service first, so your team trades hands-on control for speed and specialist depth, making it less suitable for organizations that need full visibility and control over every forensic decision.
Forensic analysts and incident responders who need to extract strings from binaries and disk images without spinning up heavyweight tools should start with bstrings. It handles both ASCII and Unicode extraction with regex filtering in a single command-line pass, which cuts analysis time when you're triaging hundreds of files across a compromised filesystem. Skip this if your team relies on GUI-driven forensic suites; bstrings is deliberately minimal and won't replace EnCase or similar platforms, but it excels when you need speed and scripting integration.
