Amsterdam-based cybersecurity company Oneleet has secured $33 million in Series A funding. The round was led by Dawn Capital, with backing from high-profile investors, including Frank Slootman (former CEO of Snowflake and ServiceNow), Arash Ferdowsi (co-founder of Dropbox), Y Combinator, and several experienced CISOs.
The new capital injection will accelerate its expansion by hiring more security engineers, advancing its technology capabilities, and scaling proven go-to-market strategies. A particular focus will be placed on enhancing the platform with intelligent automation across different areas of cybersecurity.
With this funding, Oneleet is also doubling down on its belief that compliance alone is not sufficient.
Closing the gap between paper compliance and real security
For many companies, earning SOC 2 or ISO 27001 certifications has become a checkbox exercise to secure contracts. Too often, this results in staged penetration tests, staged exercises, and screenshots that satisfy auditors but fail to build genuine protection. The outcome is a certificate on paper, but systems remain vulnerable.
Oneleet was founded by Bryan Onel and his wife Ora Onel and college friend Erik Vogelzang in 2022. With backgrounds in penetration testing against corporations and government agencies, saw a pattern wherein organisations with valid certifications were still breached quickly. This revealed a broken system where compliance outweighed real security.
Oneleet’s solution is to merge the two into one approach, ensuring that robust defences naturally meet compliance requirements rather than the other way around.
A unified platform
The company’s platform eliminates the need for multiple vendors by bringing together essential services into a single system. It integrates penetration testing, code scanning, cloud posture management, attack surface monitoring, mobile device management, and employee security training under one roof.
Instead of organisations piecing together fragmented tools, Oneleet delivers end-to-end coverage in one place. This integrated design speeds up compliance processes, helps companies exceed audit standards, and reduces risks that come from relying on third-party systems. By owning and managing its full security stack, the company provides consistent results and takes complete responsibility for keeping systems protected.
The platform also guarantees compliance outcomes by embedding rigorous security practices into day-to-day operations. Compliance becomes the outcome of good security rather than a separate process built around checklists.
Bryan Onel, CEO of Oneleet, said, “From our first call with Dawn, we knew we’d found the right partner. They understood the space deeply and immediately grasped what we’re building: compliance as the wedge, security as the substance. Their conviction, professionalism, and enthusiasm were evident from day one—Henry Mason was on a plane from London to San Francisco within 24 hours to meet in person.”
He added: “We use AI extensively—but responsibly. AI works in the background for threat modeling and risk assessments, but clients never see hallucinations because we verify everything first with human expertise, where technology falls short. The proof is in outcomes: We regularly win customers from major competitors after those companies lost deals due to inadequate security. We implement real security, and they close the deals they previously couldn’t.”
