Enforce least privilege to reduce attack vectors.

Block untrusted execution and replace standing admin rights with controlled, application-level elevation to shrink the privilege abuse window.

Removing admin rights alone doesn’t stop ransomware from executing. It does make it harder for attackers to persist, escalate, and take over the environment. Least privilege works best when paired with execution control. First, you prevent untrusted software from running. Then, you restrict and tightly control how administrative privileges are used.

Enforce least privilege by elevating approved applications versus entire users. You can now make privileged access time-bound, policy-bound, and auditable to reduce your attack surface.

How it applies across your environment

Endpoints



Elevate applications, not users. Grant admin rights to specific approved applications, not entire user accounts. This prevents attackers from inheriting full local admin control if a user session is compromised.



Eliminate dormant and unnecessary admin accounts. Remove stale local admins and unused privileged accounts that attackers commonly exploit for persistence and lateral movement.



Constrain what elevated applications can do. Restrict elevated apps launching other applications, creating scheduled tasks, modifying registry keys, or accessing credential stores like LSASS.



Block untrusted software by default. If unknown software can’t execute, it can’t request elevation or abuse admin privileges in the first place.

Remove forgotten standing privilege and cut risks immediately

Network and cloud



Restrict management protocols to hardened devices only.Limit RDP, SMB, WinRM, SSH, and administrative consoles to explicitly approved devices. Stolen credentials can’t be used from rogue endpoints.



Enforce device validation in addition to credentials.Require access to originate from an approved device and authorized network, so valid passwords or intercepted tokens aren’t enough without a trusted device.



Detect and respond to abnormal admin behavior in real time.Flag unusual elevation patterns, privilege escalation attempts, or lateral admin activity to reduce dwell time.



Prevent unauthorized devices from joining the network.Block rogue or unmanaged devices from gaining a foothold where privileged operations could be attempted.

The fewer places admin rights can be used, the less opportunity attackers have to weaponize them
