At the same time, many vendors in the network security and SASE (secure access service edge) space have also expanded into providing security for the growing use of AI itself, directly addressing the widespread need for protecting AI applications and agents.

Across IT infrastructure, top vendors are rolling out advancements around AI-powered threat prevention while also taking initial steps to move into enabling quantum-resistant encryption. Many vendors are also adding AI-driven assistance into their SASE platforms. A number of companies have also doubled down on providing network detection and response that uses new AI capabilities to correlate network telemetry with other sources, as a way to better prevent threats in real time. And for edge environments, many industry vendors are implementing AI-powered functionality to boost visibility and analyze risk within the operational technology (OT) and IoT space.
