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.
Network security teams building custom detection pipelines or forensic tooling will get the most from PcapPlusPlus; it's a library, not an appliance, so you control exactly how packets flow through your analysis logic instead of fighting vendor constraints. With 2,987 GitHub stars and active protocol support across Linux, Windows, and macOS, you're working with code that's been stress-tested by incident responders and threat hunters. Skip this if your team lacks C++ engineering resources or expects a packaged UI; PcapPlusPlus demands integration work and won't replace commercial PCAP analysis platforms.
