About Synack
At a glance
Synack is a cybersecurity company specializing in Security Operations, founded in 2013 and headquartered in Redwood City, United States. It has raised $107.25M in total funding, employs about 893 people, and is privately held.
Synack operates a Penetration Testing as a Service (PTaaS) platform that combines human security researchers with technology to conduct security testing. The company was founded in 2013 by Jay Kaplan and Dr. Mark Kuhr, both former NSA technical security experts, with the goal of transforming security testing by uniting human intelligence with a scalable platform. The Synack platform connects organizations with the Synack Red Team, a vetted community of security researchers who perform penetration testing across various attack surfaces. The platform offers multiple testing capabilities including network pentesting, application pentesting, API pentesting, and adversarial testing for AI/LLM applications. In 2024, Synack integrated Attack Surface Discovery with pentesting capabilities on their platform. The company's approach differs from traditional pentesting by providing real-time access to findings, remediation information, and analytics rather than just static reports. Synack also developed SmartScan for intelligent vulnerability assessments and the Attacker Resistance Score to help customers track security progress over time. Synack serves both commercial and government sectors, achieving FedRAMP Moderate Authorized designation in 2023 for security testing in the public sector. The company has raised over $110 million in funding from investors including Kleiner Perkins, Notable Capital, B Capital Group, C5 Capital, M12, and others. Synack maintains operations with over 1000 active Red Team members conducting security testing for customers globally.
