About the Company

  • Security Level 5 is a Bay Area AI security nonprofit working with AI labs and US intelligence agencies to defend frontier models from priority nation-state-level threats.
  • We are a small technical team that moves fast and is growing quickly.
  • Our mission is to design the first datacenter purpose-built to Security Level 5, the standard for defending frontier labs against attackers with nation-state resources and billion-dollar budgets.
  • We wrote v0.1 with input from frontier-lab CISOs and US security and intelligence officials.
  • We are designing SL5 architectures for real AI workloads and standing up the reference stack to guide lab buildouts.
  • The first SL5 components are expected this year, with at-scale build in 2027.
  • The stack must withstand nation-states, keep researchers productive, remain affordable, and ship in 2-3 years.
