Prismor and Sublime Security serve entirely different threat landscapes: Prismor secures AI agent tool calls (destructive commands, secret leaks, package supply chain risk) while Sublime defends email (BEC, phishing). Choose Prismor if you deploy coding agents like Claude Code or LangChain and need runtime guardrails; choose Sublime if your priority is email security with low false positives and custom detection.
Prismor intercepts every AI agent tool call before it runs, blocking destructive commands and cloaking secrets at the runtime boundary.

What users praise
- • Verdicts show matched detections and signal analysis — analysts can read why, not trust a score
- • Sublime Script is a YARA-like language your engineers can inspect, test, and tune
- • ASA auto-triages user-reported phishing end to end, cutting the abuse-mailbox backlog
- • ADÉ authors backtested, environment-specific detections that land ready for one-click approval
What frustrates them
- • Community footprint is thin — one video thread, and no independent Reddit or HN validation
- • Vendor efficiency claims (80% faster, 70% fewer FPs) are unverified by third parties
- • Tuning workload is real and continuous if no one owns the rule library
- • Not set-and-forget — teams replacing a legacy SEG should expect an operational shift
