Product

One platform to identify, measure, mitigate, and insure AI risk.

A network of AI agents represented as cubes, with one agent selected

Inventory

We identify AI agents across your organization.

An AI agent connected to identified risk findings

Identify and measure risks

We analyze every agent across our risk framework.

An AI agent surrounded by allowed and blocked actions

Mitigate

We integrate guardrails and propose structural changes to reduce risk surface.

Insure the remaining risk

Remaining risks transferred to a stand-alone AI policy.

How your policies respond to agent failures today

Harbor maps agent failures to the policies that respond, then models exposure across the portfolio.

Agent risks responding on each line

47 agent risks in the Harbor register, each mapped to the traditional line that picks it up today. A risk can respond on more than one line.

Cross-checked against our proprietary risk framework

Every agent risk sits inside one research-led framework built with Stanford, MIT, and NYU. Failure modes say what breaks and who pays. Measurable hazards show how we know it is likely.

Failure mode

SF–01

Unauthorized autonomous actions

An agent with the authority to act — send, pay, close, change — takes an action nobody intended. Unlike a wrong answer, the action is already executed when the failure is noticed. At machine speed, one flawed decision can repeat across hundreds of accounts before a human sees it.

Example — A customer-service agent authorised to issue goodwill credits misreads a policy update and refunds full order value to every open complaint overnight. 1,400 customers are credited before morning review.

Prompt injection

Crafted text in a message, document, or web page is treated by the agent as an instruction rather than data, overriding its operating rules. It is not a loss in itself — it is the condition that can turn a well-behaved agent into one that leaks, pays, or acts on someone else's behalf.

Why it's measurable — Harbor runs a standard suite of injection attempts against the deployed agent and records how often they succeed, what guardrails intervene, and what the agent could reach if they did not.

Understand the exposure across your portfolio

From a single insured to the whole portfolio: score it, quantify it, and watch it move.

Score against our benchmarks

Every insured is rated on controls and hazards, benchmarked against comparable deployments Harbor has assessed. Ratings roll up by line, sector, and model provider.

Model and quantify

Frequency and severity views per failure mode, portfolio loss distributions, and correlated-event scenarios across shared infrastructure.

Live monitoring over the portfolio

Accumulation metrics, realistic disaster scenarios, and ratings tracked continuously across the portfolio — with every observed incident feeding back into the model.
