Synack

Cybersecurity · Redwood City, United States · Founded 2013

A human-powered security solution offering scalable continuous testing for enterprise applications and networks MoreLess

Synack is a cybersecurity startup that provides a premier security testing platform. Its primary service is continuous penetration testing, also known as "pentesting", which is a simulated cyber attack on a computer system to check for exploitable vulnerabilities. This is done by Synack's Red Team, a global team of highly skilled security researchers. They cover a wide range of areas including cloud, APIs, web apps, host infrastructure, and mobile.

Synack's clients are companies that want to ensure their digital assets are secure. The company operates in the cybersecurity market, which is a growing sector due to the increasing number of cyber threats and the digital transformation of businesses.

The business model of Synack is based on providing continuous and scalable security testing. Unlike traditional one-off pentests, Synack's service can be launched in days, not weeks, and reduces the client's risk over time. The company makes money by charging clients for these services.

Synack also offers real-time and customizable reporting for security teams, CISOs, or auditors. This gives clients complete visibility and control over all researchers and testing across their environment. The company also helps improve responsiveness, triage, and remediate vulnerabilities with integrated workflows.

In summary, Synack provides a comprehensive and continuous security testing service that helps companies stay ahead of cyber threats.
