Midgate
In private development

Security and governance for the AI you already run.

One layer over every model, agent, and gateway you run. Midgate reconstructs each agent run end to end, surfaces the AI nobody approved, catches injection and data exfiltration mid-run, and enforces your policy before an action lands. All of it inside your own network.

Works on top of
Bedrock
Your estate

You have more AI running than the list says.

It arrives in four places, on four different timelines, and almost never through one team. Midgate covers all of them from the same record.

The assistants your teams shipped

Customer-facing chat, internal helpdesk, and the copilots embedded in your own products. High volume, real users, and a direct line to your data.

  • support chat
  • internal helpdesk
  • product copilots
  • retrieval over internal docs
Where it goes wrong

A user, or a document the assistant retrieves, talks the model into revealing something it should not, or into calling a tool on their behalf.

Midgate records every prompt, response, and retrieval, links them into one run, and flags injection and data leakage as it happens. Arm a rule and the response is masked or held before it reaches the user.

Agents with commit rights

Assistants that read your repositories, open pull requests, and run commands. They hold the most sensitive access in the company and often the least oversight.

  • code review
  • PR authoring
  • test generation
  • refactor agents
  • MCP tool servers
Where it goes wrong

A comment in an issue, a README, or a dependency carries instructions the agent follows. Each tool call looks ordinary on its own.

Midgate captures the tool calls and links them back to the input that triggered them, so a poisoned comment and the command it produced read as one chain rather than two unrelated events.

Agents that run without a person watching

Multi-step work that plans, delegates to other agents, and acts on the result. Runs measured in hours, sometimes days.

  • claims and case processing
  • research agents
  • ops automation
  • agent-to-agent handoffs
  • scheduled runs
Where it goes wrong

Nothing in any single step looks wrong. The compromise at step three only becomes visible at step forty, by which point the run has already acted.

Midgate keeps the whole trajectory as one record and evaluates policy before each action lands, so a run can be stopped mid-flight instead of investigated afterwards.

The AI inside your data jobs

Model calls buried in extraction, enrichment, scoring, and document processing. No interface, no user, and usually no record beyond a bill.

  • document extraction
  • classification
  • enrichment
  • summarization jobs
  • scheduled scoring
Where it goes wrong

A model or provider is swapped in a config change nobody reviewed, or a job quietly starts sending records to an endpoint that was never approved.

Every model, provider, and agent that appears in your traffic is inventoried, so an unapproved endpoint or a changed model shows up as a finding rather than a surprise in the audit.

The gap

Adoption is running ahead of control.

Independent research puts numbers on the distance between what teams believe they can see and what is actually running.

82%

found shadow AI agents in the past year. In the same survey, 68% said they had high confidence in their visibility.

65%

reported at least one AI-related incident in the past year.

19%

are highly confident they fully retire the agents they stand up.

What it does

Record. Decide. Enforce.

Built for estates where agents call tools, hand work to each other, and run for hours at a time.

01 · Record

Every run, reconstructable

Prompts, responses, tool calls, and handoffs between agents, captured once and linked into the run they belong to.

→ one incident view instead of five log searches
02 · Discover

The AI nobody approved

Every model, provider, and agent in your traffic, inventoried. Anything off your approved list is flagged.

→ an inventory nobody had to fill in by hand
03 · Detect

Injection, leaks, exfiltration

Tool-chain attacks surface as one linked chain tagged to MITRE technique IDs, not scattered alerts.

→ findings that drop into playbooks you already run
04 · Customize

Custom detectors

Your rules, your agentic workflows, your thresholds. It runs in your network, so it adapts to your architecture instead of the reverse.

→ a detector from one sentence, tested on your own history
05 · Enforce

Policy-driven control

Deterministic policy, evaluated before an action lands. Shadow mode first, then block, mask, or route to a human.

→ rehearsal numbers before anything is armed
06 · Prove

Adversarial testing, audit-ready

Attack your own agents to measure coverage, and generate audit evidence from the record.

→ coverage measured, not asserted
Multi-agent

Built for agents that run for days.

A single call is easy to watch. A dozen agents delegating across a multi-day run is not: risk propagates and compounds across steps, and the failure at hour nine began somewhere at hour one.

Long-horizon runs

Attacks that cannot happen in a single turn, multi-turn poisoning, tool chaining, persistent injection, are caught across the whole trajectory.

Agent-to-agent handoffs

Interop protocols move work between agents but leave identity and authorization to you. Midgate records and governs what actually crossed.

One policy, every agent

Control stops depending on each team remembering to add guardrails to its own agent.

Long-running agents you can leave running.

Replay an incident end to end

When something is flagged, the next question is what did it touch? Midgate reconstructs the run so you can answer it.

  • The injected document, the record it opened, and the address it tried to reach: one incident, in order.
  • Tagged to MITRE technique IDs, so it drops into existing playbooks.
  • The same view serves the investigation and the audit.

Every AI in the company, mapped

A single posture score for the project, and the agents pulling it down, named.

  • Agents ranked by what they can do, not how often they run.
  • Unapproved tools appear on the map.
  • Each agent graded on how well it is built, before someone else tests it.

Each miss becomes a new rule you approve, so the same attack cannot work twice.

Test your defences with generated attacks

Attacks are generated for your specific business and replayed against your detectors, so coverage is a measured number rather than a claim.

  • Attacks generated for your business, not a generic list.
  • Every miss becomes a rule you approve.
  • Coverage is a measured number, not a claim.

Audit evidence, generated from the record

The evidence auditors ask for is derived from the record itself, not assembled by hand.

  • Oversight verified in practice, not on paper.
  • Describe a risk in a sentence; the rule is written and proved against your own history.
  • Maps to EU AI Act, NIST AI RMF, and ISO 42001.
How it runs

How it runs.

Works with what you have

Sits above the providers and gateways you already use.

Cannot break production

Out of the request path, so it can never slow or drop a live call.

Your data never leaves

Recording, detection, and investigation all happen inside your network.

Every rule starts in shadow. Nothing destructive happens without a person approving it.
