Every prompt, document and tool call is checked before it acts.
AgentShield-X sits between your users, your data and your AI agents. It cleans what goes in, authorizes what goes out, cages what runs, and keeps a tamper-evident record of all of it.
- allowed
- healed: unsafe part removed
- blocked
Four stations, one rule: deny unless proven safe.
Every scanner error, timeout, missing model or unreachable approver ends in a refusal, never a pass.
- Reads before the model doesStrips hidden characters, decodes obfuscation, removes injected instructions and redacts secrets in text, retrieved documents, tool output and images.
- Authorizes every actionEach tool call is checked against a registry, a schema, roles, attribute rules, an egress allow-list and, when risky, a human approval. Anything unexpected is denied.
- Runs code in a cageGenerated code runs in a throw-away container or pod with no network, no mounts and a read-only filesystem, optionally under gVisor and a kernel policy.
- Guards MCP serversA proxy blocks poisoned tool descriptions, notices tools that change after approval, cleans results, and refuses server-initiated sampling.
- Proves what happenedDecisions go into a Merkle ledger signed with Ed25519 and ML-DSA-65. Anchor checkpoints elsewhere and a rewritten history cannot pass verification.
- Ships as policyTools and rules live in reviewable YAML, validated strictly. A typo stops the service instead of weakening it.
Real results from the engine.
Pick an input. These were captured by running AgentShield-X 2.2.0 while this site was built. They are recorded results, not a live demo.
Run the same checks yourself with agentshield scan-text "...".
What it cannot do yet.
A security tool should say where it stops.
- New phrasings of an attack can slip past the rules. On unseen paraphrases the rule layer caught 2 of 10. A learned classifier hook exists; train or supply a model, and keep tools least-privilege.
- Identity is pseudonymous. The zero-knowledge proof shows key possession; it is not an anonymous credential system.
- Compliance mappings are evidence, not certification.
- Parts are unproven in the build environment: Kubernetes, Cilium and Tetragon, OPA, real container isolation and the GitHub workflows have not been executed. See the verification table.
