US EditionNir Zuk’s cybersecurity co Cylake launches with $45m
Cylake targets governments and regulated sectors with an AI-driven cybersecurity platform ensuring data sovereignty and full control, backed by $45 million from Greylock Partners.
- Nir Zuk unveiled Cylake on March 5, 2026, with a $45 million seed round led by Greylock Partners and cofounders Wilson Xu and Ehud Shamir.
- Zuk argues the industry shifted too far to the cloud, leaving regulated customers unable to use public cloud products, so Cylake was created to ensure data sovereignty and full control.
- The company is building an AI-native platform designed to run on-premises or in private clouds, working with limited development partners and targeting early 2027 commercial availability.
- Investors see a large market opportunity as Asheem Chandna, partner at Greylock, said the next cybersecurity generation will rely on AI, noting a 'hundred billion dollar plus opportunity' despite a high bar for Zuk's success.
- Nearly $14 billion in cybersecurity funding in 2025 shows rising threats from AI-enabled attacks and the war in Iran, while Cylake's contrarian hardware/on-premises approach targets regulated customers.
