Summary

Researchers built NOVA (Network and Open-Source Vulnerability Analyzer), an AI system that automatically discovers vulnerabilities in open-source software, and found 14,090 previously unknown vulnerabilities in 3,915 projects in just two months. The discovery shows that AI is dramatically speeding up how fast vulnerabilities are found, which means attackers have less time before patches are released. The company is addressing this by partnering with open-source maintainers to responsibly disclose vulnerabilities and deploying Advanced Virtual Patching, which uses AI to deliver protections within hours rather than waiting the typical 55 days for traditional patches.

Solution / Mitigation

Advanced Virtual Patching is designed to operate at the speed of AI and collapse the exposure window from the industry-average 55 days it takes to deploy a traditional patch down into a near-zero window of exposure. The source also recommends organizations deploy vulnerability management, zero-trust network architecture (a security model that verifies every access request, whether from inside or outside the network), software supply chain security, and other attack surface reduction best practices.
