DLP (Data Loss Prevention)
Data Loss Prevention is a category of security tooling that inspects data in motion, at rest, and in use to detect and block exfiltration of sensitive information, credentials, source code, customer data, regulated personal data. In telecom, DLP complements egress filtering at OSS/BSS and corporate boundaries and is tied into incident response workflows.

DLP in context
OSS/BSS platforms (provisioning, charging, mediation, order management) hold the highest-value subscriber and revenue data on the operator side. They are heavily targeted for fraud and insider abuse and are increasingly in scope for regulatory obligations like NIS2 and the UK Telecoms Security Act.
To place DLP in the wider telecom-security picture, review Data Localization, EDR, NOC, Packet, Patch and SECA.
