The removal of admin rights provides great proactive protection. We need to secure the components that execute malicious payloads, especially in important apps that browse the web or read email. The numbers in this report prove that removing admin rights will give you protection for Outlook, Office, IE, and Edge

Enforcing Least Privilege and Removing Admin Rights Eliminates 56% of Critical Microsoft Vulnerabilities

So Why Don't More Businesses Enforce Least Privilege?

The latest BeyondTrust annual report found that of the 196 Critical vulnerabilities reported in 2020, more than half would be mitigated by removing local admin rights from users. That's a compelling case for enforcing least privilege.

So why are so many organizations hesitant to implement a full scale least privilege policy? The tension between security and productivity is often the barrier that prevents the removal of local admin rights from all users.

To address this challenge, BeyondTrust offers industry leading Endpoint Privilege Management solutions that are easily deployed and dynamically exert granular control over access to applications, tasks, and scripts. By elevating access for applications without elevating the user’s actual privileges, the experience is seamless to end users and keeps them productive and protected.
