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.

OpenAI's Privacy Filter is a 1.5-billion-parameter open-weight model trained specifically for detecting and redacting personally identifiable information (PII) from text. Released today under the Apache 2.0 license, it achieves over 96% F1 score on standard PII detection benchmarks and is compact enough to run locally on consumer hardware — no API required. The model handles standard PII categories (names, emails, phone numbers, SSNs, addresses) plus context-dependent identifiers like account numbers, medical record IDs, and quasi-identifiers that become sensitive in combination. It's designed to run as a pre-processing filter before text hits larger models, letting teams handle sensitive data without sending it to the cloud. Releasing this under Apache 2.0 is a meaningful move. Most enterprise PII tools are expensive, closed, and API-gated. A small, accurate, locally-deployable open-weight model changes the economics for startups, researchers, and developers building with sensitive data. It slots cleanly into data pipelines, agent pre-processors, and document handling workflows.
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.”
“A 96%+ F1 PII model at 1.5B parameters that runs locally and ships under Apache 2.0 is immediately useful. Drop it at the front of any data pipeline that handles user-generated content, medical records, or financial data. The size means you can run it on CPU if needed. This is the kind of open-source release that actually changes what's practical to build.”
“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.”
“96% F1 sounds great until you're in healthcare or finance where the 4% miss rate is a compliance catastrophe. PII detection at production scale requires near-perfect recall, not just high F1. And 'context-dependent quasi-identifiers' are notoriously hard — I'd want to see the breakdown by PII type, not just the aggregate score, before trusting this in a regulated environment.”
“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.”
“The open-source PII filtering layer is missing infrastructure in the AI stack. As agents process more sensitive documents, the ability to strip PII before data hits any external model becomes critical. This is the kind of foundational tooling that enables an entire category of privacy-preserving AI applications — especially in healthcare, legal, and finance.”
“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.”
“For anyone building tools that handle user-submitted content, this is a gift. Running PII redaction locally before storing or analyzing content is good practice that was previously too expensive to implement at scale. Apache 2.0 means no legal friction for commercial use.”
