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 tripling headcount this year.
  • We wrote the first version of the standard with input from CISOs and senior security staff at the frontier labs, and US security and intelligence officials.
  • We are designing the SL5 architectures purpose-built for frontier AI workloads, and standing up the reference tech stack to guide labs' buildouts.
  • This stack has to hold against nation-states, not destroy researchers' productivity, not cost more than labs can pay, and ship in 2-3 years.
