Cryptographic non-repudiation for autonomous agent tool calls

Cryptographic non-repudiation for autonomous agent tool calls targets a $2.4B = 30,000 enterprises × $80K ACV total addressable market with medium saturation and a year-over-year growth rate of 12% YoY growth in security and compliance tooling (Gartner 2024 estimate for enterprise security apps).

Key trends driving demand: Agentization of workflows — as autonomous agents manage more high-risk operations, demand for verifiable accountability increases because organizations must audit and attribute actions.; Regulatory pressure — financial and critical infrastructure regulators are clarifying expectations for logging, attestations, and non-repudiation which pushes procurement toward provable receipts.; Standardization of signing — open-source projects and cloud KMS maturity lower technical barriers for cryptographic attestation, enabling interoperable receipt formats.; Shift from mutable logs to tamper-evident proofs — organizations prefer cryptographic proofs over editable logs for legal and insurance defensibility which creates demand for receipts as a service..
