About Seal Security
At a glance
Seal Security is a cybersecurity company specializing in Application Security, founded in 2022 and headquartered in Wilmington, United States. It has raised $20.4M in total funding, employs about 113 people, and is privately held.
Seal Security provides automated vulnerability remediation for open source software components. The company was founded by three software vulnerability experts with over 30 years of combined experience in vulnerability mitigation and exploitation. Seal Security creates production-ready, standalone patches that fix vulnerabilities in place without requiring forced upgrades, migrations, or breaking changes. The platform backports security fixes for both application dependencies (direct and transitive) and Linux OS packages, including containers and end-of-life distributions. The solution centralizes remediation across CI pipelines, enabling security teams to patch vulnerabilities independently of development teams. The company operates with a 72-hour remediation SLA for critical and high severity findings. Their approach allows organizations to maintain vulnerability-free builds and stay audit-ready while reducing manual effort and technical debt. The platform addresses the challenge of patching open source vulnerabilities without disrupting existing codebases or requiring major version upgrades. Seal Security holds ISO 27001 and SOC 2 Type 2 certifications. The company is backed by investors including Crew Capital, Vertex Ventures Israel, PayPal Alumni Fund, Cyber Club London, and SBI.
