Mindgard is one of the strongest platforms for AI security testing and red teaming. HexTyx provides equivalent testing depth and extends further — into agent and RAG security, runtime monitoring, governance, compliance evidence, and executive reporting. Both are enterprise-grade; the difference is scope.
Mindgard and HexTyx occupy the most similar territory in this comparison series — both are enterprise AI security testing platforms, both perform AI red teaming, both test for prompt injection. The meaningful differences emerge in scope: Mindgard specialises in pre-deployment security testing and vulnerability discovery. HexTyx adds runtime monitoring, governance workflows, compliance evidence generation, and the executive reporting that increasingly makes or breaks enterprise procurement reviews.
Mindgard is an AI security company focused on AI security testing and AI red teaming. The platform helps organisations identify vulnerabilities in AI systems before attackers exploit them — through AI red teaming, adversarial testing, vulnerability discovery, model security assessment, and prompt attack evaluation. It is widely regarded as one of the strongest vendors specifically in the AI security testing category.
HexTyx is an enterprise AI security, governance, compliance, and assurance platform. It combines AI security testing, AI red teaming, prompt injection assessment, agent and RAG security validation, runtime monitoring, governance reporting, and compliance automation — aiming to secure AI systems throughout their entire lifecycle rather than focusing solely on pre-deployment testing.

Mindgard is strongest here. The platform provides adversarial testing, prompt attack simulation, vulnerability discovery, and security assessments of deployed AI systems. For technical security teams, this is deep, focused capability.
HexTyx provides equivalent testing depth while extending into operational assurance. Prompt injection testing covers direct, indirect, multi-step, and multimodal attacks. Agent security testing covers tool abuse, permission escalation, memory poisoning, and workflow compromise. RAG security testing covers unauthorised retrieval, cross-tenant leakage, document poisoning, and access-control validation. Findings map to governance frameworks automatically.
Mindgard has built a strong reputation in AI red teaming — adversarial attack simulation, vulnerability identification, security posture evaluation, and resilience measurement. For technical security teams, these capabilities provide valuable insight.
HexTyx approaches red teaming through both technical and governance lenses: prompt injection campaigns, agent attack simulations, autonomous workflow attacks, multi-agent compromise scenarios, and compliance-linked testing. The output serves not only security teams but also risk teams, compliance teams, and executive audiences.
Agentic AI is transforming enterprise operations. Unlike chatbots, agents execute actions, access systems, trigger workflows, and maintain memory — creating unique security challenges that standard prompt testing doesn't fully address.
Mindgard's agent testing capabilities continue to evolve as the market matures. Coverage generally centres on adversarial evaluation of agent behaviour.
HexTyx treats agent security as a primary capability: tool abuse testing, MCP security validation, memory security testing, workflow security, and runtime monitoring — designed for organisations deploying agents in production.
Testing identifies vulnerabilities before deployment. Runtime monitoring detects attacks after deployment. Mindgard's primary focus is pre-deployment security testing; runtime protection is generally secondary.
HexTyx supports runtime visibility as an integrated platform component: threat detection, behavioural monitoring, agent observation, risk scoring, and incident reporting — providing ongoing operational assurance alongside pre-deployment testing.
Mindgard focuses primarily on technical security validation. Governance capabilities are not the platform's primary objective — organisations typically manage compliance workflows separately using additional tooling.
HexTyx treats governance as a core platform component: AI inventories, risk registers, governance workflows, compliance dashboards, and executive reporting. Security testing findings flow directly into compliance evidence — reducing manual effort and creating the audit-ready reports that NIST AI RMF, EU AI Act, SOC 2, and ISO 27001 require. This becomes decisive when an enterprise security questionnaire or regulatory review asks for tested controls, not just documented ones.
Bottom line: The HexTyx AI Security Assessment covers red teaming, agent security, RAG security, and governance readiness — mapped to major compliance frameworks. Free, 10 minutes.
