Synack

SYNACK, often stylized Synack, is a cybersecurity company that operates a crowdsourced security testing platform. It provides managed penetration testing and vulnerability discovery by leveraging a vetted community of security researchers. Clients run tests against networks, applications, and infrastructure within defined scopes and legal frameworks, with findings delivered in a secure, auditable format.

The platform combines automated scanning with manual testing conducted by researchers from the Synack Red Team. Researchers are screened and continuously evaluated, and earnings are tied to validated findings. Clients receive remediation guidance, risk ratings, and supporting evidence through a secure portal, enabling prioritized remediation and compliance documentation.

Historically, Synack has targeted enterprise and government customers seeking scalable, authorized security testing. The service emphasizes controlled, repeatable testing under client-defined permissions and confidentiality requirements, aiming to integrate into existing security programs and governance structures.

Critically, the model represents a blend of traditional penetration testing and crowdsourced security, aiming to increase test coverage and reduce time to discovery while maintaining enterprise-grade governance. It has contributed to broader discussions around bug bounty programs and managed security services, offering an alternative to conventional, in-house testing approaches. As with other security offerings, feedback has included considerations of scope management, reliance on a curated researcher pool, and the balance between depth of testing and scalability.
