The Infrastructure Firewall for
Gemini at Work & Vertex AI Agents

Observability tells you after an agent breaks your database or burns $10,000 in token loops. ThumbGate intercepts and validates every tool execution in <0.5 milliseconds before it hits your production infrastructure.

Enterprise Agent Vulnerabilities Solved In-Line

1. Runaway Tool Loops & Token Burn

When autonomous agents encounter unclear query schemas or external network timeouts, they enter recursive re-query loops (e.g. 300M+ tokens burned in recent agent incidents). ThumbGate's ActiveSaddler dynamic curriculum and loop governor halts runaway sequences at the first sign of cyclical failure.

2. Unauthorized Bulk Mutations

Gemini Workspace or BigQuery agents generating DML queries can accidentally execute unindexed table drops, partition truncations, or unbounded customer updates. ThumbGate checks blast-radius parameters and enforces human sign-off before mutations execute.

3. PII & Secret Exfiltration Diodes

Enterprise MCP servers and webhooks frequently leak customer authentication tokens or internal IDs. ThumbGate sanitizes all outbound parameter payloads, blocking unallowlisted IP ranges and untrusted destinations.

4. Continuous DPO / RLHF Memory

Every time a developer or human supervisor hits thumbs-down on an agent action, ThumbGate automatically compiles that correction into a permanent, deterministic prevention rule enforced across your entire agent fleet.

Architecture & Compliance Standards

ThumbGate conforms to NIST SP 800-53 Rev. 5 controls (AC-3, AU-2, AU-12, SI-4) and OMB M-24-10. Deployment options include zero-telemetry air-gapped on-premise containers, Google Cloud Run, and Kubernetes sidecar diodes.
