Eventually, VPNs can break under strain, and that creates an issue around business continuity.

Simply put, if VPNs become overwhelmed by increased traffic, connectivity may fail, and the ability for employees to access the network may be impacted, the concept of business continuity suffers as a result.

ZTNA Moves Beyond VPNs With VPN technology becoming suspect in the rapid expansion of remote workforces, CISOs and IT pros are looking for alternatives to ensure reliable and secure connections into the network from remote workers.

SASE differs significantly from the VPN and ZTNA models by leveraging a native cloud architecture that is built on the concepts of SD-WAN. According to Gartner, SASE is an identity-driven connectivity platform that uses a native cloud architecture to support secure connectivity at the network edge that is globally distributed.

SASE Address the Problems of VPNs, ZTNA - and More With VPNs coming up short and ZTNA lacking critical functionality, such as ease of scale and performance management, it is quickly becoming evident that CISOs may need to take a long hard look at SASE. SASE addresses the all too common problems that VPNs are introducing into a rapidly evolving remote work paradigm, while still offering the application-centric security that ZTNA brings to the table.
