Doberman features
- MCP proxy. Intercepts every tool call from an agent and normalizes it into a SecurityObject.
- Three-verdict engine. Deterministic core returns PASS, AUTH (human approval) or BLOCK before execution.
- Raise-only learning. Behavioral baselines can only tighten; weakening requires 2FA-gated approval.
- Mode dial. Four security postures (Light, Balanced, Strict, Paranoid) adjust thresholds and default verdicts.
- Tiered authentication. Local confirmation, TOTP 2FA, and time-limited role elevation for AUTH actions.
- Local audit log. Append-only, redacted log of decisions with reason codes and HMAC fingerprints.
- Extensible plugins. Custom detectors, auth providers, or audit sinks can be added via Python entry points.
- Fail-closed default. Any error, uncertainty or unknown case results in a BLOCK verdict.
OpenAI Codex features
- Parallel agent execution. Runs multiple coding agents simultaneously, using tools to verify work until requirements are met.
- Reusable cloud environments. Keeps tasks running in the cloud with per-repo environments that persist across devices.
- Automated PR reviews. Scans pull requests, surfaces findings, and answers questions to accelerate code review.
- Plugin ecosystem. Connects to external tools and adds specialized capabilities via plugins.
- Cross-platform access. Available in ChatGPT, IDE extensions, CLI, and web, all linked to a single account.
- Secure shared workspaces. Business plan offers admin controls and shared repositories for team collaboration.
