Cyber security is an arms race with talent and technology at the helm – the side that employs the most advanced and intelligent resources will ultimately win.
– Jay Kaplan, CEO

About Us

To beat the modern cyber adversary, we can’t settle for another layer of ineffective defense. We need to go on offense. Synack delivers what standard defensive technologies don’t – protective offensive testing. We work with the world’s most exclusive crowd of security researchers and give them access to a powerful platform for trusted security testing. Together, they deliver vulnerabilities, compliance documentation, and powerful data.

Synack protects some of the largest organizations in the world by effectively and efficiently reducing their true security risk and increasing their resistance to cyber attack. This is Security Without Compromise. With headquarters in Redwood City, California, Synack is a global organization with regional presence in cities around the US and EMEA. Our Synack Red team researchers represent over 55 countries around the world.

Synack: What's in a Name?


To make a handshake work, two individuals have to reach out and acknowledge one another. Same goes for a digital TCP-handshake.

There are three steps in this handshake — Syn, Syn-ack, & Ack — required to negotiate and establish a TCP session between two computers. Much like the power of a human handshake, this connection creates a path for the transfer of information or data, which is at the core of our business.
