Sublime Security

22 mentions across 2 sources · 71% positive (weighted across 2 sources)

YouTube, Lemmy

What users praise

  • • Evidence-backed verdicts let analysts audit why a message was flagged, unlike opaque scoring engines
  • • Sublime Script detections are readable and tunable by in-house detection engineers
  • • Native overlay on M365 and Workspace avoids rerouting mail to a third-party filter
  • • Autonomous triage of user-reported phishing directly attacks the analyst backlog problem

What frustrates them

  • • No Reddit, HN, GitHub, or review-site feedback exists to validate daily reliability at scale
  • • Viewers repeatedly ask for SOAR integration guidance — supporting docs/content are clearly thin
  • • Requires advanced detection-engineering skills; not plug-and-play for lean security teams
  • • Public pricing is absent, forcing every evaluation through a sales conversation
