Admin By Request EPM gives organizations control over who and what can elevate on their endpoints, without standing up servers, databases, or a dedicated admin team to run it. The model is least privilege: a user or an application receives the specific access its task requires and nothing more. This closes off a common attack route, since permanent local admin rights are what an attacker inherits when malware executes or a credential is stolen. Removing admin rights does not push users back into support queues. When someone needs a longer stretch of elevated work, they run an Admin Session that expires on its own. When they need only one program elevated, Run As Admin handles that alone and leaves the rest of the system unprivileged. Requests can be approved through the portal, the mobile app, or the API. Files receive an OPSWAT MetaDefender reputation check before elevation, and software that has already been vetted can clear automatically through pre-approval or the AI and Machine Learning approval engine. A single agent supports Windows, macOS, and Linux and behaves the same whether the endpoint is online or offline. Auditing and inventory are included as standard.

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.

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.
