iProov has launched its new human approval service to help enterprises deploying AI agents maintain trusted human oversight of high-risk actions. Implementing the Human Approval and Presence Specification released in September 2026, the iProov service provides cryptographically verifiable proof that the genuine, right human person approved an action an agent was seeking to execute.
iProov has launched a human approval service implementing the Human Approval and Presence Specification for AI agent gateways.
The service provides cryptographically verifiable proof that the genuine, right human approved an action an agent sought to execute.
It integrates with agentgateway, the open-source AI agent gateway developed by solo.io, and Cerbos as its first policy-engine partner.
The proof of humanity uses iProov's Dynamic and Express technologies, relied on by national governments and major organizations.
The HAPS engine ties proof of humanity to proof that the person approved a specific action and delivers an auditable, non-repudiable certificate.
The Open Source HAPS specification, a partial Rust reference implementation and test vectors are available under the Apache-2.0 license.
"Cerbos controls and secures what decisions AI Agents can make in an organization, and under what conditions," said Alex Olivier, Chief Product Officer and Co-Founder of Cerbos. "Our partnership with iProov introduces a new level of control, enabling organizations to require approval from the right human before a high-consequence action can proceed. By adding this decision capability, we are giving organizations the confidence to delegate an even greater range of tasks to their AI agents than ever before while still retaining human oversight and accountability."
"For organizations to realize the full potential of agentic AI, they need to task agents with increasingly consequential responsibilities. But some actions must remain subject to human control, approval and accountability," said Andrew Bud, founder and CEO of iProov. "Our new HAPS service provides cryptographically verifiable proof that the real, right human being, confirmed by iProov Genuine Human Presence, has approved a specific action. Cerbos determines when such human approval is required and calls the HAPS service. By requiring a genuine human face as part of the approval process, we secure the process against agent impersonation. Because no matter how smart they become, agents will never have faces."
When a Cerbos policy requires human approval, the action is held, and iProov's hosted HAPS service is called. The service shows the named approver the exact action and its scope. If they approve, they complete an iProov genuine human presence check. iProov then issues a signed, single-use credential bound to that exact action, and only then is the agent's action released. If any detail changes, such as the amount or destination of a payment, the credential no longer matches, and the action is blocked.
The HAPS specification remains open, so any gateway, policy engine, or relying party can implement HAPS-compliant approval, backed by iProov or by other forms of proof.
The announcement comes as industry leaders increasingly recognize the need for stronger human oversight of autonomous AI agents. In an October 2026 Microsoft Security blog, Microsoft highlighted the importance of policies that can "require cryptographically provable human approval for a high-impact step."
Dominic Forrest, Chief Technology Officer at iProov, will present iProov's HAPS service and its integration with agentgateway and Cerbos at AgntCon North America in San Jose, October 22-23.
