Seqrite Endpoint Protection 8.3 (Control Center)

IDS IPS

Print Friendly, PDF & Email

When you create a network where numerous machines are deployed, security is of paramount concern. With IDS/IPS, you can detect attacks. This detection implements a security layer to all communications and cordons your systems from unwanted intrusions or attack. You can also take actions like blocking the attacker’s IP for certain time, and send an alert message to the administrator.

Note
The IDS/IPS feature is available only in the clients with Microsoft Windows.

You can create different policies with varying IDS/IPS settings and apply them to the groups so that each has separate policies based on the requirement.
For FAQ about networking, see FAQ.
