Agentic AI security overlaps multiple adjacent categories (prompt injection protection, AI posture management, runtime monitoring, and network/SASE enforcement), so competitors differ significantly by technical approach and enforcement locus.
Acquisitions and platform consolidation in related areas indicate that some functionality may be bundled into larger network/SASE or cloud security platforms over time. Buyers should consider product roadmaps and potential integration with existing platform vendors.
| Starting Price | Not publicly disclosed; engagement is demonstration-led | Contact sales | Contact sales |
| Primary Use Case | Enterprises requiring centralized discovery, governance, and runtime controls for AI agents | Teams focused on prompt injection and LLM input/output protections | Organizations seeking broader ML/AI security posture controls and model scanning |
| Key Strength | Focus on centralized visibility for agents; vendor documentation of compliance artifacts in a trust center | Established in discussions around prompt injection defense | Broad ML security feature set used in enterprise evaluations |
| Key Weakness | Limited independent public reviews; limited publicly available technical enforcement detail and ROI evidence | Pricing and deployment fit vary; may focus on LLM layer rather than full agent runtime | Can be feature-rich and potentially more expensive; may focus on ML supply-chain controls rather than agent runtime enforcement |

Based on vendor materials, Onyx emphasizes comprehensive visibility across agents, a staged lifecycle approach (discovery → governance → runtime protection), and documented compliance artifacts and BYOC deployment options.
