The funding round comes on the heels of another record-setting year for VulnCheck. Key milestones from the past 12 months include:
- Increasing year-over-year enterprise Annual Recurring Revenue (ARR) by 557% and government ARR by 306%
- Climbing from No. 143 to No. 28 in less than one year, for the all-time CVE assignment with nearly 2,000 CVEs (common vulnerabilities and exposures) assigned
- Adding nearly 7,000 new users to VulnCheck Community and bringing the total number of cybersecurity vendors, practitioners and vulnerability management teams with access to VulnCheck KEV and VulnCheck NVD++ to more than 13,000
- Adding nearly 900 software and hardware vulnerabilities to its Known Exploited Vulnerabilities (KEV) list throughout 2025, representing a 25% year-over-year expansion. According to VulnCheck research, 32% of these vulnerabilities were exploited on or before the day of CVE disclosure, an increase of 36% compared to 2024
VulnCheck delivers a fully autonomous, machine-consumable dataset that analyzes first-party evidence of exploitation and scans more than 500 million records maintained on all CVEs from over 500 sources to identify the information that truly matters for defenders. This removes long-standing bottlenecks and allows security teams to act at machine speed. The platform refreshes its data sources multiple times per day, allowing teams to counter emerging cyber threats with unprecedented velocity and context into threat actor activity, ransomware associations and existing exploit POCs in the wild.
The funding underscores continued market validation. In 2025, VulnCheck was recognized among the most prestigious and coveted cybersecurity industry startup competitions in the market. The company’s achievements included being selected as a SINET16 Innovator for 2025, which is an honor reserved for emerging companies that are identified from a panel of 112 judges as the most innovative and compelling technologies in their fields, addressing cybersecurity threats and vulnerabilities.
