Bridges Facebook's many safety related teams, as well as external partners, and engages cross-industry groups and safety experts working on technical safety solutions in order to improve safety efforts internally.
  • Threat Intelligence – protects and defends Facebook and its community by surfacing, tracking, and mitigating global advanced threats and informing security decision-making across the company.

  • Data Protection: builds the systems and frameworks for engineers to fulfill the commitments made to people on Facebook in handling their data.
  • Product Security: supports and ensures secure engineering across all of the Facebook family of products. This is accomplished in the following ways:
    • Conducting assessments to evaluate the security of Facebook's codebase
    • Making code secure and easier to write for all of Facebook's codebases by writing better abstractions and helping migrate existing code
    • Developing automated tools that leverage static and dynamic analysis, and operate our Bug Bounty Program
