atlas-detect is an open-source Rust tool that maps MITRE ATLAS techniques to real-time detection rules for LLM systems and AI agents. MITRE ATLAS is the adversarial threat landscape framework for AI — think ATT&CK but for machine learning systems — and atlas-detect is the first practical, deployable detection engine built on top of it. It ships with 97 pre-built detection rules covering 16 adversarial tactics, from prompt injection and model inversion to training data poisoning. The engine is written in Rust and designed for single-pass regex scanning, making it fast enough for inline deployment in API gateways or agent middleware. You feed it prompt-response pairs (or full conversation logs) and it returns matched technique IDs, severity ratings, and structured evidence. Think of it as a Snort/Suricata ruleset, but for the semantic attack surface of LLMs. With only 4 stars as of today, atlas-detect is an extremely early project — but it's filling a gap that no major security vendor has meaningfully addressed. As enterprises deploy AI agents with real tool access and real consequences, ATLAS-aligned detection will become a compliance requirement. This is the seed of that tooling.

Moonbounce converts content moderation policy documents into executable, runtime-enforced logic — bridging the gap between what a platform says it prohibits and what it actually enforces in real time. Founded by Brett Levenson, former Business Integrity lead at Facebook/Meta, it launched out of stealth with a $12M seed round co-led by Amplify Partners and StepStone Group. The "policy as code" approach means moderation rules written in natural language get compiled into deterministic enforcement logic that responds in under 300 milliseconds. This matters for AI platforms where generative content flows too fast for traditional human-in-the-loop review. Current customers include AI companion apps (Channel AI, Dippy AI, Moescape) and image generation platforms (Civitai), which are the sectors currently operating in the most contested content gray zones. The broader context is that as AI-generated content scales, the enforcement gap between stated policy and actual behavior becomes a legal and reputational liability. Moonbounce is betting that every platform deploying a generative AI product will eventually need a compliance layer — and that being "policy as code" rather than "rules as vibes" is the defensible position.
Reviewer scorecard
“97 detection rules for adversarial LLM attacks and it runs in a single pass — this is the kind of foundational security tooling the ecosystem has been missing. Drop this into your API gateway and you immediately have ATLAS coverage. Exactly what regulated industries need.”
“Sub-300ms enforcement at the API layer means I can ship generative features without building a custom moderation pipeline from scratch. The policy-as-code abstraction is the right mental model — if I can read and audit the compiled enforcement logic, I can trust it more than a black-box classifier.”
“Regex-based detection for semantic attacks is fundamentally limited. Sophisticated prompt injection won't pattern-match to static rules — attackers will route around them in days. This might work for known attack signatures but it's a weak defense against anything novel.”
“Policy documents are inherently ambiguous, and compiling ambiguity into deterministic enforcement creates false confidence. Edge cases will still need human review, and the question is whether you're adding a compliance theater layer or actually reducing harm. The AI companion customer base also raises questions about who's using this and for what.”
“MITRE ATLAS coverage is going to show up in AI security audits within 12-18 months the same way ATT&CK coverage shows up in SOC2 reviews today. Building on this framework now, even imperfectly, is the right long-term investment.”
“Trust and safety infrastructure for AI-generated content is a fundamentally unsolved problem at scale. Moonbounce is approaching it as a developer infrastructure play rather than a compliance consulting play, which is the right bet — platforms need APIs, not auditors.”
“Not relevant to creative workflows, but I'll note that any tool protecting AI agents from manipulation ultimately protects the outputs I rely on. This is infrastructure that benefits everyone downstream.”
“Platforms like Civitai hosting AI-generated imagery have faced real harm without adequate enforcement tools. A system that lets platforms encode their actual values into runtime behavior — rather than aspirational policy pages — is meaningful for building creator communities that aren't destroyed by misuse.”
