Cyberthreat intelligence provider VulnCheck Inc. today announced that it has raised $25 million in new funding to scale up growth and expand its intelligence capabilities.

Founded in 2021, Vulncheck provides organizations with real-time exploit and vulnerability intelligence to predict potential attack vectors accurately, including exploit intelligence technology that addresses the gap between published software vulnerabilities and those actively weaponized in real-world attacks.

Vulncheck’s platform works by collecting data from vulnerability disclosures, exploit repositories, malware samples, dark web forums and other threat intelligence feeds. The data is then normalized, enriched and mapped to standardized identifiers such as common vulnerabilities and exposure to enable correlation between known vulnerabilities and confirmed exploit activity.

Machine-readable feeds and application programming interfaces allow customers to ingest exploit intelligence directly into security information and event management systems, vulnerability scanners and patch management tools. The system also continuously updates exploit status as new activity is detected.

The platform helps security teams prioritize remediation based on confirmed exploit presence rather than severity scoring alone and supports automated alerting and reporting workflows, enabling organizations to align patching and mitigation efforts with verified threat activity.

Vulncheck said it has seen strong growth, with its annual recurring revenue increasing a 557% over the last 12 months and government annual recurring revenue by 306%. It didn’t provide absolute numbers.

The Series B round was led by Sorenson Capital, with National Grid Partners, Ten Eleven Ventures and In-Q-Tel Inc. also participating.

“VulnCheck’s fundamentally different approach has allowed the company to sustain its hypergrowth trajectory,” said Ken Elefant, a partner at Sorenson Capital. “Legacy vulnerability management solutions were built for manual analyst workflows and cover only a fraction of known vulnerabilities.

By contrast, he added, “VulnCheck combines the largest breadth of public and first-party exploit intelligence and delivers it first for machine-to-machine consumption, with human review as a secondary outcome, to drastically close the exploitation-timing gap. This approach has it well-positioned in the market for years to come.”

The new funding takes the total raised by Vulncheck to $45 million. The company previously raised a Series A round of $12 million in March 2025.
