Automating threat analysis and response with Cloudy

Security professionals everywhere face a paradox: while more data provides the visibility needed to catch threats, it also makes it harder for humans to process it all and find what's important. When there’s a sudden spike in suspicious traffic, every second counts. But for many security teams — especially lean ones — it’s hard to quickly figure out what’s going on. Finding a root cause means diving into dashboards, filtering logs, and cross-referencing threat feeds.

Best Practices for Securing Generative AI with SASE

As Generative AI revolutionizes businesses everywhere, security and IT leaders find themselves in a tough spot. Executives are mandating speedy adoption of Generative AI tools to drive efficiency and stay abreast of competitors. Meanwhile, IT and Security teams must rapidly develop an AI Security Strategy, even before the organization really understands exactly how it plans to adopt and deploy Generative AI.

Beyond the ban: A better way to secure generative AI applications

The revolution is already inside your organization, and it's happening at the speed of a keystroke. Every day, employees turn to generative artificial intelligence (GenAI) for help with everything from drafting emails to debugging code. And while using GenAI boosts productivity—a win for the organization—this also creates a significant data security risk: employees may potentially share sensitive information with a third party.
