LIMS - a Carrier-grade LI Solution

The Utimaco Lawful Interception Management System (LIMS) is a state-of-the-art monitoring solution for fixed and mobile networks. It helps telecom operators and Internet service providers fulfill their legal obligation to intercept calls and data while maintaining maximum privacy protection.

Utimaco LIMS enables target-based monitoring of public communications services including telephone calls, mobile data and Internet-based services such as e-mail, Voice-over-IP, instant messaging and others. The system acts as a bridge or mediator between the service provider’s network and the law enforcement’s monitoring centers. Strong security provisions prevent unauthorized access, secure all private user data and facilitate security audits by comprehensive logging.
