T3MP3ST vs Sublime Security
Side-by-side comparison of features, pricing, and ratings
At a glance
| Dimension | T3MP3ST | Sublime Security |
|---|---|---|
| Pricing | Free (AGPL-3.0 open-source) | Contact for pricing |
| Primary Use Case | Autonomous red-teaming of LLMs | Enterprise email security (BEC, phishing) |
| Deployment | Self-hosted, no cloud dependency | Cloud-based, integrates with M365/Workspace |
| Target Users | AI safety researchers, security engineers | Enterprise SOC teams, detection engineers |
| Key Feature | Multi-agent swarm for automated attacks | Autonomous agents (ASA, ADÉ) for triage and detection |
If you need to stress-test LLMs proactively and have the in-house expertise to manage open-source tooling, T3MP3ST is the free, autonomous choice. For organizations fighting targeted email threats with a need for transparent, agent-driven detection and low false positives, Sublime Security's enterprise platform delivers — but at an unknown cost and with a steeper onboarding for small teams.
T3MP3ST is an open-source multi-agent offensive-security harness that turns the AI coding agent you already run into an autonomous vulnerability hunter.

T3MP3ST
31 mentions across 4 sources · 53% positive — mixed (averaged across 4 sources)
Hacker News, Bluesky, GitHub, Lemmy
What users praise
- • Autonomous multi-agent orchestration reduces manual oversight for red-teaming.
- • Modular plugin architecture enables custom attack strategies and extensibility.
- • Free, open-source, and self-hosted with no cloud dependency.
- • Keyless operation using existing AI coding agents like Claude Code.
What frustrates them
- • CLI detection fails for common tools like Claude Code and Codex CLI.
- • Setting up local LLM (e.g., Ollama) is poorly documented.
- • No guidance for adding authentication headers in web scans.
- • Essential documentation for basic configuration is missing or confusing.

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

Frequently Asked Questions
T3MP3ST vs Sublime Security: which should you choose?
If you need to stress-test LLMs proactively and have the in-house expertise to manage open-source tooling, T3MP3ST is the free, autonomous choice. For organizations fighting targeted email threats with a need for transparent, agent-driven detection and low false positives, Sublime Security's enterprise platform delivers — but at an unknown cost and with a steeper onboarding for small teams.
Can T3MP3ST be used for email security?
No, T3MP3ST is focused on red-teaming LLMs, not email. Sublime Security addresses email security specifically.
Does Sublime Security offer a free tier?
No, Sublime requires contacting sales for pricing. However, they offer a free EML Analyzer tool for email analysis.
Which tool supports custom detection rules?
Both do: T3MP3ST via modular plugin architecture for attack strategies, and Sublime via Sublime Script (YARA-like) for email detections.
Is T3MP3ST suitable for non-technical users?
No, it's not recommended for non-technical users as it requires comfort with CLI and self-hosting, and lacks a GUI-focused experience.
Does Sublime Security integrate with Google Workspace?
Yes, Sublime integrates with both Microsoft 365 and Google Workspace.
Can I run T3MP3ST in the cloud?
While T3MP3ST is self-hosted and has no cloud dependency, you can deploy it on your own cloud infrastructure.
Does Sublime Security provide automated incident response?
Yes, it offers features like quarantine, alert, and remediation as part of its automated response.
Which tool is better for a small business with limited security staff?
Neither is ideal: T3MP3ST requires security expertise; Sublime is intended for enterprises. However, if email security is needed, Sublime's AI agents can reduce manual effort.
