- Specific ports or IPs must be allowed or blocked.
- Network traffic needs to be controlled for compliance or performance.

Using SanerCVEM ensures:
- Centralized rule deployment across multiple endpoints.
- Reduced manual errors and improved consistency.
 - Auditability and automation of firewall configurations.

Form Field Explanations
