This approach is designed to help organizations remediate vulnerabilities across direct and transitive dependencies without requiring new versions or developer intervention. Key services include fixing vulnerabilities in container images, securing Linux distributions including end-of-life versions, and delivering compliance-ready base images for frameworks such as FedRAMP, PCI DSS 4.0, and NYDFS 500. Testimonials on Seal.Security highlight the platform’s impact. “Thanks to Seal’s product, we swiftly addressed security vulnerabilities and updated outdated code packages, saving us valuable time, which we estimated by months of engineering work,” said Gad Meyer, Director of Software Engineering at PayPal. Matt Farmer, Principal Site Reliability Engineer at cybersecurity research platform Censys, noted, “Seal Security enabled us to eliminate a major ongoing risk to our development roadmap. The integration with their solution was simple, allowing us to quickly achieve significant patching coverage and ensure the seamless remediation of vulnerabilities.”
Seal Security is co-founded by CEO Itamar Sher, CTO Lev Pachmanov, and CPO Alon Navon. According to their LinkedIn profiles, Itamar previously founded Gilgamesh Cyber Solutions and worked in vulnerability research roles. Lev held senior engineering and architecture roles at PayPal, Curv, and Cymmetria before co-founding Seal. Alon also came from PayPal and Curv, where he managed product development, and earlier served for nearly nine years in the Israel Defense Forces with responsibilities in cybersecurity and product leadership. Together, they bring a mix of vulnerability research, product management, and infrastructure experience to Seal’s mission of addressing open source software risks.
