Security Level 5 Task Force

13/n Check out our announcement blog post: sl5taskforce.substack.com/p/releasing-th…

12/n We invite frontier AI labs, government agencies, datacenter operators, and security researchers to engage with this work. Read the full standard and get involved: standard.sl5.org

1/n Today we're releasing the first public draft of the Security Level 5 (SL5) standard, designed to protect frontier AI models against nation-state adversaries. This v0.1 focuses on long lead time interventions: the things that need to start now, before SL5 is urgently needed. standard.sl5.org

🛡️ Introducing the Security Level 5 (SL5) Standard. This is the first revision of our SL5 Standard, focused on long lead time requirements: interventions that must be planned years in advance, such as facility construction, hardware procurement, and organizational capability development. Some requirements represent significant departures from standard industry practice. We believe these measures are necessary at this security level, while recognizing the need to address real operational constraints. sl5.org/projects/secur… Future revisions will further optimize the intersection of SL5 security and practical deployment, expand mappings from DoD IL6 and related frameworks, and refine areas where government involvement may ultimately be required. We welcome collaboration. This concludes SL5 Shipmas. We’re excited to share this work and continue building toward robust, scalable security for frontier AI systems.

🔎Introducing the Sensitivity Levels Framework (SenL) - an Insider Risk Management Framework for the AI industry: SenL proposes industry-adapted clearance levels for AI labs, designed to proportionally reduce insider and personnel risk while remaining feasible under private-sector legal, operational, and cultural constraints. It translates government-style continuous evaluation across seven domains into a tiered model that labs can deploy today, with optional pathways to integrate government information sharing as policy allows. Speed, cost effectiveness, and scalability are prioritized. sl5.org/projects/sensi…

📘 All the SL5 Novel Recommendations are now live. Today we’re releasing the remaining reports on Network Security, Physical Security, and Supply Chain Security, completing the set of novel recommendations for Security Level 5 🚀 Hope you enjoy & looking forward to your comments! sl5.org/reports/networ… sl5.org/reports/physic… sl5.org/reports/supply…

📘 Today we’re releasing two focused reports with novel recommendations for Machine Security and Personnel Security, addressing critical gaps between current industry practices and Security Level 5 requirements. sl5.org/reports/machin… sl5.org/reports/person… Bonus release: a local, privacy-first speech to text toolkit for sensitive meetings. sl5.org/projects/secur… More coming tomorrow.

🚀 Now open source: the IL6 Control Catalog. In response to popular demand, we are opensourcing our internal tool that we used while writing the SL5 Standard: an interactive, searchable way to explore FedRAMP High and DoD IL6 security controls without digging through scattered PDFs. Built to bridge complex compliance with practical implementation. sl5.org/projects/il6-c… #SL5

🎄 SL5 Shipmas is here. It’s been an active past few months at the #SL5TaskForce! Over the coming days, we are releasing open standards, frameworks, and tools to help frontier AI labs reach nation state grade security, and to inform forward-looking securing strategies across the AI industry. First release drops shortly. stay tuned

AGI is on the horizon. Many expect AI could reach AGI within 2–5 years, followed closely by superintelligence (ASI). We must ensure these systems can’t be hijacked by bad actors or nation-states, and plan for loss-of-control risks. Learn more: sl5taskforce.org
