Security-first compliance platform by ex-pen testers, bundling automation, penetration testing, and vCISO for SOC 2 and ISO 27001.
Oneleet is a security-first compliance platform founded in 2022 by Bryan Onel, Ora Onel, and Erik Vogelzang. Part of Y Combinator's S22 batch, the company is based in Amsterdam and has raised $35M in total funding, including a $33M Series A led by Dawn Capital in October 2025. Notable investors include Dropbox co-founder Arash Ferdowsi and former Snowflake/ServiceNow CEO Frank Slootman.
What sets Oneleet apart is its founding team: professional penetration testers who spent over a decade breaking into Fortune 500 companies. Rather than treating compliance as a checkbox exercise, Oneleet starts with actually making companies secure and then uses that security posture to achieve certifications like SOC 2, ISO 27001, HIPAA, GDPR, PCI DSS, NIST 800-171, and DORA.
The platform bundles compliance automation with built-in penetration testing, dark web monitoring, code scanning, mobile device monitoring, and virtual CISO guidance. With $9M+ ARR and a 4.9/5 G2 rating, Oneleet has carved out a niche among startups and growth-stage companies that want genuine security, not just a certificate on the wall.
Starts around $12K/yr for small teams. Mid-sized SaaS companies with multiple frameworks can exceed $50K/yr. Price includes pen testing (normally $5K-$10K separately), platform access, monitoring, vCISO time, and audit support. No self-serve signup; requires live demo for scoped proposal.
Series A-C startup with 30-300 employees needing SOC 2 to close enterprise sales, led by a CTO or security-conscious founder who values actual security over just getting a certificate.
