Where are Edge security and Tokenization typically deployed?

• A. Edge security in a DMZ in a customer-hosted environment; Tokenization inside the firewall to replace sensitive data with fake data
• B. Edge security inside the firewall; Tokenization in the DMZ
• C. Both in the public cloud
• D. Edge security in the internal LAN; Tokenization in a separate data center

Answer: (A)

Edge security belongs at the network boundary where it can inspect and guard traffic entering from the internet, typically in a DMZ, so external threats are filtered before anything reaches internal systems. Tokenization, on the other hand, is a data-protection measure that keeps real sensitive data inside the trusted boundary and substitutes it with tokens that are safe to use elsewhere. Deploying edge security in the DMZ and keeping tokenization inside the firewall provides defense-in-depth: the edge handles external exposure while the internal system environment protects and controls access to sensitive data through tokenization. Placing edge security inside the firewall or tokenization in the DMZ weakens the protective boundary, and using cloud or internal LAN-only placements doesn’t align with the typical perimeter-focused approach described.
