Where this offering fits
Network DLP examines data movement at selected communication boundaries. It is useful when the organisation needs policy on outbound transfers, but effectiveness depends on traffic reaching the inspection path and on the supported handling of encrypted content. Treat the network path and the data-detection requirement as separate parts of the design.
Architecture and rollout decisions
Map egress routes, proxies, email paths and services that may bypass central inspection. Use approved data examples to evaluate the chosen GTB deployment against required channels. Agree how unavailable inspection, unsupported files and encrypted sessions are handled. Introduce enforcement after observing legitimate transfers and reviewing exceptions with application owners. A UAE multi-branch rollout should record which sites use the same egress and which have local breakout.
An evaluation scenario for this offering
Use a synthetic sensitive file and a visually similar permitted document across the agreed egress paths. Review the policy result and the evidence the analyst receives. Repeat through a branch path that does not use the main gateway so the coverage boundary is explicit. Where encrypted traffic is involved, validate the documented treatment rather than claiming inspection merely because a connection is logged. Record the narrow exception needed for any legitimate business transfer.
Evidence to request for this scope
- Document inspected channels and explicit visibility gaps on the current traffic diagram.
- Test permitted and prohibited transfers with representative sizes and supported formats.
- Assign responsibility for reviewing blocked business traffic and changing a narrowly scoped exception.
