Trustwise is a platform focused on AI trust management and runtime security for agentic AI systems. The company provides tools designed to monitor, govern, and secure AI agents and models throughout their operational lifecycle, with a particular emphasis on runtime behavior rather than perimeter-level defenses. Their core product, Harmony AI, functions as an AI Control Tower that delivers runtime protection and policy enforcement across prompts, agents, and models. The platform uses an "inside-out" architecture, embedding trust logic at the decision layer of AI systems. Key capabilities include tool misuse prevention, data leak blocking, agent drift containment, action tracing, and automated policy enforcement. The infrastructure is underpinned by six agents, twelve small language models (SLMs), fourteen datasets, thirty guardrail modules, 1,100 mapped controls, 20,000 red team prompts, and 21 million synthetic personas. Trustwise delivers its platform via APIs, SDKs, Model Context Protocols (MCPs), and Guardian Agents, allowing integration into existing architectures. The modular design allows organizations to adopt individual components such as action shielding, purple teaming, cost optimization, or compliance enforcement incrementally. The company targets large enterprises operating in high-stakes sectors including healthcare, finance, and industrial operations. Named customers include KPMG, the NHS, Lloyds, and Yum! Brands. The platform is positioned for use by security leaders, CIOs, compliance teams, and developers building or scaling agentic AI systems.
