Distant entry is vital for operations groups, distributors, and contractors to configure, keep, and troubleshoot OT property with out time-consuming and dear visits. Nonetheless, many present distant entry options create safety backdoors or include many tradeoffs Cisco Safe Gear Entry (SEA) is fixing the challenges of deploying safe distant entry to operational property at scale and brings all the advantages of a zero belief community entry (ZTNA) resolution to industrial operations. There isn’t any devoted {hardware} to put in and handle and no advanced firewall guidelines to configure and keep.
If you wish to study extra, be part of us for a session on ZTNA on October 25 for IIoT World Cybersecurity Day.Â
