Silobreaker

Silobreaker’s platform ingests large volumes of open-source, technical, and dark web data and applies entity extraction, enrichment, and visualization to turn raw information into decision-ready intelligence for cyber threat, corporate security, and geopolitical risk teams. Rather than being a narrow indicator-of-compromise feed, it is positioned as a broader analyst workbench: correlating actors, campaigns, and events across sources so intelligence teams can produce reporting without stitching together data manually from dozens of separate tools.

Founded in 2005 and headquartered in London with significant engineering and data operations based in Sweden, Silobreaker has built a two-decade customer base spanning corporate security, government, military, and financial services. It supported NATO’s Cooperative Cyber Defence Centre of Excellence (CCDCOE) with threat intelligence contributions to a published policy brief on cybersecurity threats to maritime port infrastructure, a concrete, independently verifiable example of its analytical output being used in a real defense-policy context. In January 2022, Marlin Equity Partners acquired a majority stake in the company, with co-founders Kristofer Mansson and Per Lindh continuing to lead and retaining minority ownership; in 2025 the company added a distribution partnership with Carahsoft to reach U.S. federal, state, and local government buyers more directly.

For CISOs and intelligence teams, Silobreaker is most relevant as an analyst-facing correlation and reporting layer sitting on top of threat feeds and OSINT sources, rather than as a source of unique indicators itself — its value is largely a function of how well an organization’s analysts can use its search, visualization, and reporting tools to turn volume into judgment.
