Traditional solutions fail to protect IoT and OT devices

As businesses become increasingly connected to enable visibility, they must prioritize secure connectivity and access to IoT and OT devices. The vast majority of these devices were not designed with security in mind, leaving the businesses using them more vulnerable to attack.  Therefore, protecting valuable IoT and OT assets in offices, factories, and branch or retail locations is imperative to enable a safe, secure, and productive work environment—but this is impossible using yesterday’s network and security technologies.

Improve plant and people safety

Direct connectivity with inline zero trust security makes it fast for users and vendors to connect to and repair equipment, minimizing downtime.
