You control:

Who can access data.

Which applications can handle it.

When it can be accessed.

What actions are permitted.

Endpoint group, and more.
‍Create policies based on:

User or group.

Endpoint or organization.

Application.

File location and type.

Time of access.
When someone attempts to access a file: Approved? Access is granted within defined limits. Not approved? Access is blocked instantly.
‍You can also:

Trigger alerts for excessive file activity.

Automatically lock down systems during suspicious behavior.

Track every read, write, move, and delete action.

Integrate automated containment for large-scale exfiltration attempts.
Every action is logged and every access is accountable.

Your benefits

Stop unauthorized data access
Sensitive files stay protected even from trusted applications.
Reduce insider threat risk
Access is limited by policy, not assumption.
Gain complete visibility
See exactly who touched what data and when.
Respond to threats in real time
Trigger automated containment when abnormal file behavior is detected.
Pair data access policies with application containment.
Limit which applications can access sensitive folders, and then restrict what those applications can do.
For example:
‍Allow Excel to open finance files. Prevent it from launching PowerShell or making outbound connections. Now even if a trusted app is hijacked, it can’t exfiltrate data.
