Our CEO, @dan_lahav, spoke at @jpmorgan's Global Cyber Innovation Summit in NYC about cybersecurity in the era of frontier AI, exploring how AI systems fail and how to build trust where traditional security tools fall short.
A timely conversation for a fast-moving field.
We recently helped close a handful of zero-days in CUPS, the default printing system on most Linux distros. Our AI security eval system keeps surfacing real vulnerabilities, with similar findings in Soft Serve and QuickJS a few months ago. Responsibly disclosed
We evaluated GPT-5.5 before release, testing cyber capabilities across our private benchmark suites. We found clear gains over GPT-5.4: stronger performance at lower costs.
As models become more capable, understanding and reducing their security risks becomes increasingly
Introducing GPT-5.5
A new class of intelligence for real work and powering agents, built to understand complex goals, use tools, check its work, and carry more tasks through to completion. It marks a new way of getting computer work done.
