What real users say: Anthropic Cybersecurity Skills vs Sublime Security

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

Anthropic Cybersecurity Skills

18 mentions across 5 sources · 45% positive — mixed (weighted across 5 sources)

Hacker News, YouTube, Product Hunt, GitHub, Lemmy

What users praise

  • • 817 skills across 29 security domains, including serious depth in cloud (60) and threat hunting (55)
  • • Every skill carries MITRE ATT&CK technique IDs; many map to NIST CSF 2.0 and ATLAS
  • • Progressive disclosure keeps token cost low — ~40-token frontmatter before full workflow body loads
  • • Works with Claude Code, Copilot, Cursor, Codex CLI, and 20+ Markdown-reading agents

What frustrates them

  • • Zero published field reports of the library used in a production SOC
  • • Skill counts shift between videos (753 → 754 → 817), complicating versioning and audits
  • • One open GitHub issue (Sept 2026) cites incomplete refs and incorrect ATT&CK mappings
  • • Requires intermediate agent-config skills; beginners will struggle to wire it up

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
