Short answer
Data loss prevention (DLP) controls detect and block sensitive information, such as personal information covered by POPIA, payment data or credentials, as it moves through web, SaaS, email, endpoints and AI interactions. Netskope DLP, delivered by FirstNet, applies these controls from one policy engine, including prompts sent to AI tools.
In detail
How a DLP rollout typically runs:
- Discovery: which data matters most, where it lives and which channels it leaves through
- Policy design for the first use case, such as SaaS uploads or AI prompts
- A pilot with a smaller group of users before production
- Tuning after go-live to balance protection with usability
- Reporting on DLP alerts, either reviewed by FirstNet or sent to your SIEM
Within Microsoft 365, FirstNet can also apply sensitivity labels, encryption and retention as part of its Microsoft 365 security work.
DLP supports your compliance goals but does not guarantee compliance on its own; outcomes depend on your setup, governance and operation.
Many organisations start with one high-risk channel and extend DLP to endpoint and email once the first policies are proven.
