Announcing the Secure Intelligence Institute

Perplexity has launched the Secure Intelligence Institute, a research center focused on improving security, privacy, and trust in frontier AI through internal research and collaboration with academia and industry. The institute builds on the company’s previous AI-security efforts, including a Trail of Bits audit of its Comet browser, Comet’s defense-in-depth architecture, the open-source BrowseSafe benchmark covering more than 14,700 attack scenarios, and guidance submitted to NIST on securing autonomous AI agents. Dr. Ninghui Li, a Purdue University computer science professor and fellow of ACM and IEEE with extensive security research leadership experience, will serve as the institute’s inaugural director. SII will study areas including authentication, usable privacy and security, robust machine learning, and defenses for agentic AI systems, with the stated goal of producing research that both advances the field and strengthens deployed AI products.
