"SASE offerings will provide policy-based 'software defined' secure access from an infinitely tailorable network fabric in which enterprise security professionals can precisely specify the level of performance, reliability, security, and cost of every network session based on identity and context," Gartner wrote in its report introducing SASE.
With more SaaS applications in use and more employee traffic destined for cloud services, SASE takes a different approach than the legacy method of routing all traffic through the enterprise data center for inspection. Instead, access decisions are based on the identity of the entity that's at the source of the connection – whether that's a user, device, branch office, IoT device, edge-computing location, or a combination of these factors, according to Gartner. Security decisions are enforced at the endpoint while policies are defined and managed in the cloud.
At TrialCard, the decision to fast-track an untested SASE solution to hundreds of users was made easier by going with one of the company's existing networking vendors, Silver Peak. "We were already using Silver Peak in our internal networks," Van Dynhoven says. "We also used them for a connection from a data center to one of our external partners."
