Application security company OX Security has announced the close of a $60m Series B funding round to support its continued growth and innovation in the cybersecurity space.
The investment was led by DTCP, with backing from Swisscom Ventures, IBM, Evolution Equity Partners, Microsoft, and Team8. With this latest round, OX has now raised a total of $94m since its inception.
Founded in 2021 in the aftermath of the SolarWinds breach, OX Security delivers a next-generation application security platform that cuts through the noise of legacy AppSec tools. Its technology focuses on pinpointing vulnerabilities that pose real-world threats, using a proprietary Code Projection engine to assess reachability, exploitability, and business impact across the development lifecycle.
The fresh capital will be used to drive global expansion, scale product development, and further refine its AI-based approach to software risk mitigation. OX aims to help enterprises move beyond a reactive model and instead adopt a security strategy based on actionable, measurable risk reduction.
The company has seen rapid traction, hitting $10m in revenue while tripling its customer base within a year. Its solution is currently used by more than 200 companies, including high-profile names such as Microsoft, IBM, SoFi, and eToro.
OX Security CEO and co-founder Neatsun Ziv said, “Any security tool can find endless vulnerabilities and issue a nonstop stream of alerts. We’re here to tell you which specific vulnerabilities will actually get you breached – and make it painfully clear what to fix first. We built OX to solve the actual AppSec problem: not finding issues but knowing which ones to fix. That’s what gets buy-in from developers. That’s what prevents breaches, and why the market is finally ready for change.”
DTCP managing director Dean Shahar said, “We are very excited to be partnering with OX to support them in their next stage of growth. OX is the precision blade that slices through the noise of endless vulnerabilities, empowering organizations to zero in on the critical 5% that truly matter.
“This is a true paradigm shift – OX’s code projection and precise prioritization finally deliver on the broken promises of legacy security tools, whose flood of alerts has become their Achilles’ heel. As GenAI accelerates code creation beyond human scale, OX unifies fragmented AppSec solutions into a single, cohesive platform, delivering laser-sharp accuracy to secure the ever-expanding attack surface.”
