The database holds the truth. But not all truths should be seen. Hashicorp Boundary Dynamic Data Masking makes sure of that.
Boundary is built to control access at the edge. Dynamic Data Masking gives it precision inside. Instead of exposing raw values, it transforms sensitive fields on the fly. A social security number becomes XXX-XX-1234. An email becomes john*****@domain.com. The original data stays in the source, untouched. The masked data is streamed to the user based on policy.
With this, access is no longer all-or-nothing. You can give analysts, developers, or third-party tools just enough visibility to do their work, but no more. It reduces data exfiltration risk without slowing teams down. It also fits directly into zero-trust architectures—every request is checked, every field governed.
Hashicorp Boundary Dynamic Data Masking works at query time. That means no batch masking, no duplicate datasets, no drift. Rules can be role-based, time-based, or context-based. Policies can target specific columns, patterns, or matching criteria. You edit a rule; the masking changes instantly for the next request.
