Vulcan Cyber

Vulcan Cyber is an Israeli cybersecurity company focused on vulnerability risk management. The company was founded in 2018 and is headquartered in Tel Aviv. It has raised venture funding across multiple rounds, though I am not confident in the specific amounts or lead investors and will not state them here.

Vulcan Cyber's primary product is a platform that aggregates vulnerability data from security scanners and other sources, correlates it with asset and business context, and helps security and IT teams prioritize which vulnerabilities to remediate first. The core problem it addresses is the gap between the volume of vulnerabilities that scanners surface and an organization's practical capacity to patch them — commonly called the remediation gap. The primary buyers are enterprise security operations and vulnerability management teams. The platform integrates with a wide range of scanning and ticketing tools, including Tenable, Rapid7, Qualys, and Jira, allowing it to operate within existing security workflows rather than replacing them.

The flagship product is the Vulcan Cyber platform (also marketed under the name VulnStack or referred to as the Vulcan Free tier in some periods), which ingests scanner output and enriches it with threat intelligence and exploit availability data to produce a prioritized remediation queue. The company has offered a free community tier alongside its enterprise offering. Detailed public information on specific product versioning and launch dates is limited.

Vulcan Cyber competes in the vulnerability prioritization and remediation orchestration space alongside companies such as Rezilion, Nucleus Security, and Brinqa, as well as broader exposure management platforms from larger vendors like Tenable One and Qualys TruRisk. The company targets the enterprise segment and positions itself on the depth of its remediation workflow orchestration rather than scanning capability, since it does not perform its own scanning.
