Cybersecurity
Protecting enterprises with new AI-first approaches.
Overview
The rise of AI will usher in a new era in cybersecurity. Bots, deep fakes, targeted attacks and ransomware are merely the beginning. In this environment, we believe there is a tremendous opportunity for innovative technologists to build companies designed to counteract the next wave of cyber threats. Greylock eagerly wants to help initiate and advance these efforts up and down the cyber stack.
We have a distinguished, long-term track record in cybersecurity. Greylock partners have invested in, helped build, and/or worked at many of the most important companies in cyber including Palo Alto Networks, Okta, Rubrik, Sumo Logic, Abnormal Security, Cato Networks, Skyhigh Networks, Demisto, Imperva, Check Point and Sourcefire. Palo Alto Networks (the largest independent cybersecurity company), Sumo Logic, and Abnormal Security were all incubated at Greylock.
Some areas of particular interest include: cloud security, developer security, identity and access, security monitoring and automation, new algorithmic approaches for prevention, and security training.

Rajiv Batra and Lee Klarich joined Nir and the early team delivered the initial product in 2007 – a “next generation firewall” that could identify and provide fine-grained control of applications. The company went public in 2012. Today Palo Alto Networks is the world’s largest independent cybersecurity company and is a member of the S&P 500.
