Sublime Security
20 mentions across 2 sources · 80% positive (weighted across 2 sources)
YouTube, Lemmy
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
