CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Enterprise security teams processing millions of files daily across email, web, and cloud need Spectra Detect's non-execution binary analysis to catch malware at scale without sandbox lag. The platform handles up to 100 million files daily across 400+ formats and supports retro-hunt across your entire file history, which matters when you're hunting variants weeks after initial compromise. Skip this if your organization runs fewer than 100,000 files daily or needs deep SOAR automation; Spectra Detect excels at high-volume file triage and threat classification, not orchestration.
Incident responders and malware analysts who need to quickly triage RTF-based phishing attachments should use RTFSig to extract and fingerprint suspicious structural elements that commodity AV misses. The tool's free, open-source design means zero procurement friction for resource-constrained security teams running limited forensics pipelines. Skip this if you're looking for an automated detection engine; RTFSig is a manual analysis helper that requires operator judgment to interpret signature output, not a fire-and-forget scanning tool.
