UltraViolet Cyber has launched Solstice, a proprietary AI platform for application penetration testing that combines human expertise with artificial intelligence. The platform is trained on data from over 30,000 UltraViolet engagements and operates in a human-led, AI-powered architecture. Solstice aims to deliver faster engagements—approximately 20% quicker—whilst maintaining quality and providing broader attack surface coverage. The platform maintains persistent memory across engagements, carrying forward confirmed findings and application-specific behaviours to create increasingly sharper assessments. Unlike commercial AI tools trained on generic data, Solstice uses UltraViolet's proprietary knowledge base, including runbooks and historical findings. The platform operates within UltraViolet's integrated security model, where offensive findings directly inform defensive detection capabilities.

With backing from private equity, four cybersecurity companies have combined into one and have set up shop in Northern Virginia.
