Top Data Security Startups in 2026

Today, there's more data and users outside the enterprise than inside, causing the network perimeter as we know it to dissolve. We realized a new perimeter was needed, one that is built in the cloud and follows and protects data wherever it goes, so we started Netskope to redefine Cloud, Network and Data Security. Since 2012, we have built the market-leading cloud security company and an award-winning culture powered by hundreds of employees spread across offices in Santa Clara, St. Louis, Bangalore, London, Melbourne, and Tokyo. Our core values are openness, honesty, and transparency, and we purposely developed our open desk layouts and large meeting spaces to support and promote partnerships, collaboration, and teamwork. From catered lunches and office celebrations to employee recognition events (pre and hopefully post-Covid) and social professional groups such as the Awesome Women of Netskope (AWON), we strive to keep work fun, supportive and interactive. Visit us at Netskope Careers. Follow us on LinkedIn and Twitter @Netskope for more updates.

Swoop is helping unlock its potential, so that search and analysis no longer end simply with incremental insights or neatly organized search results, but with autonomous action directly at the edge. Swoop's technology has been deployed in some of the world's most sophisticated environments. Our team is purposeful in directing our technology toward solving important problems.
