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.

The software used to manage networks hasn’t kept up with the dramatic expansion of networks themselves. The Forward Networks solution is designed to help network teams eliminate network outages and reduce time to remediate errors. Its platform enables engineers and operators to visualize and search complex networks, debug configuration problems, verify network-wide policy implementations, and predict network behavior prior to deploying changes. Forward Networks builds a software replica of an entire network to analyze its behavior. Using the network copy, the software traces, indexes, and stores the collected data, monitoring things like end-to-end behavior, verification of the network’s forwarding behavior and security posture, and close monitoring of configuration changes.
