OpenObscure launches on-device AI privacy firewall

OpenObscure is a dual-licensed MIT/Apache-2.0 privacy firewall that sits between AI agents and LLM providers, encrypting PII on-device with FF1 format-preserving encryption before requests leave the machine. It also scans responses for manipulation and runs locally with no cloud dependency or telemetry.

// ANALYSIS

OpenObscure is interesting because it treats privacy as an in-process control plane, not a post-hoc policy layer. If the setup really is as light as the pitch, this has a better shot at sticking than most agent-security tools.

  • FF1 format-preserving encryption is the right call for cards, SSNs, and other structured PII because the model still sees realistic input.
  • Localhost-only, no-telemetry, and no default keys make this feel like actual security infrastructure, not a SaaS wrapper.
  • The scope is broader than a proxy: text, images, audio, and tool results are all covered, plus mobile SDKs and OpenClaw integration.
  • The EU AI Act / cognitive firewall angle is interesting, but it still needs real-world validation before anyone reads it as compliance coverage.
  • The market is already crowded with redaction tools, cloud gateways, browser extensions, and enterprise DLP, so OpenObscure wins only if setup stays frictionless.
