Communication interception is used by intelligence and law enforcement agencies in Bangladesh for national security and crime prevention. It involves monitoring phone calls, emails, and digital communications to detect threats such as cybercrime, terrorism, and smuggling.

Agencies like the National Telecommunication Monitoring Center (NTMC) oversee lawful interception. However, balancing national security with privacy rights is essential. Proper legal frameworks and oversight mechanisms are needed to ensure ethical use of interception technologies while maintaining public trust.
