If you’ve ever dealt with slow VPNs, or clunky ZTNA agents that degrade app performance, you’re not alone. Many IT teams are stuck balancing security with usability—and often end up sacrificing both. Here is a different approach. The high-performance ZTNA service that is part of a personal SASE solution from Cloudbrink can upgrade or replace traditional VPNs while fixing the performance and complexity that come from other vendors in the ZTNA and SASE space. Built as a software-only service, Cloudbrink delivers sub-20ms latency and 1Gbps+ speeds per user using dynamically deployed FAST edges and a proprietary protocol that recovers packet loss before it impacts the app. Security isn’t bolted on—it’s built in. With mutual TLS 1.3, short-lived certs, and no exposed IPs, Cloudbrink provides real zero trust without making users suffer through poor connections or overloaded POPs. If you’ve been burned by “next-gen” solutions that still feel like 2008, it might be time for something new.
