Straiker specialises in protecting AI agents at runtime — threat detection while agents operate. HexTyx secures the entire AI agent lifecycle: pre-deployment testing, MCP security validation, governance, compliance, and runtime assurance combined. Both address agent security; the difference is whether you need runtime-only or full lifecycle coverage.
The AI security market is shifting toward autonomous agents. Both HexTyx and Straiker recognise this — both focus on agent security, both address MCP risks, both provide runtime protection. The meaningful difference is lifecycle scope. Straiker specialises in identifying and responding to threats while agents are operating. HexTyx secures agents from design through deployment: testing before launch, governing while in production, and generating the compliance evidence that regulated organisations need.
Straiker is a security platform focused on protecting AI applications and autonomous AI agents. The company is known for runtime protection, agent monitoring, prompt injection defence, tool-use visibility, and agent attack detection. Straiker has gained attention for its focus on agent runtime security — protecting AI systems while they are actively operating, which aligns closely with traditional security operations models applied to AI.
HexTyx is an enterprise AI security, governance, compliance, and runtime assurance platform. Rather than focusing exclusively on runtime defence, HexTyx provides complete AI assurance from development through production: pre-deployment testing, agent and RAG security validation, MCP security assessment, runtime monitoring, governance reporting, and compliance evidence generation.

Agent security is the core strength of both platforms. Organisations deploy agents that access SaaS platforms, execute workflows, read documents, call APIs, and update systems — all with real business consequences when compromised.
Straiker focuses on runtime detection: monitoring active agent behaviour, identifying suspicious activity, providing tool interaction visibility, and defending against prompt injection while agents operate. The platform is designed to catch threats in real time.
HexTyx covers the full agent security lifecycle. Pre-deployment: agent security testing, workflow security reviews, tool permission analysis, and memory security validation. Post-deployment: runtime monitoring and threat detection. This lifecycle approach identifies risks before they reach production — Straiker's runtime protection then becomes a second line of defence rather than the first.
MCP (Model Context Protocol) allows agents to connect to tools, systems, and data sources — and every connection is a potential attack vector. Common MCP threats include unauthorised tool access, data exfiltration through tool calls, tool abuse, and prompt injection delivered through external content.
Straiker provides visibility into tool interactions and runtime behaviour to detect suspicious MCP activity.
HexTyx extends into design-time and runtime MCP controls: permission validation, tool governance assessment, security testing, runtime monitoring, and compliance mapping against MCP security requirements.
Straiker has built its reputation here — threat detection, behavioural analysis, runtime visibility, alerting, and security monitoring are primary capabilities. It aligns closely with traditional security operations models applied to AI agents.
HexTyx integrates runtime protection into a broader assurance workflow: threat detection, risk scoring, governance reporting, compliance evidence, and executive dashboards. Detection is only the first step — demonstrating organisational control is the second.
Most enterprises deploying AI use RAG systems. The risks — cross-tenant leakage, document poisoning, unauthorised retrieval — require dedicated testing methodology, not just runtime monitoring. Straiker provides runtime visibility that can surface RAG anomalies. HexTyx provides dedicated RAG security assessment: retrieval authorisation testing, chunk-level access control validation, vector database security review, and knowledge-base isolation testing — before deployment.
Straiker prioritises security operations and runtime protection. Governance functionality is generally secondary.
HexTyx treats governance as a core platform objective: AI inventories, risk classifications, governance workflows, compliance dashboards, control validation, and compliance evidence. For organisations under EU AI Act, NIST AI RMF, SOC 2, or ISO 27001 obligations, this becomes the difference between passing and failing an audit.
