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.
