Agentic Index
Hiddenlayer vs Zenity (2026)
Both extended established positions into agent security from different starting points, at 8.5 and 8 of 14.
HiddenLayer came from model security, with a scanner covering more than 35 formats and supply chain threats, detection and response against adversarial attacks and prompt injection, model genealogy and AI bill of materials governance, plus 2026 agentic runtime work. Zenity was purpose built end to end for agents across observe, govern and defend, with depth in Copilot Studio, Agentforce, Bedrock and Azure AI Foundry. Model provenance against agent platform coverage, and they answer different questions about the same estate.
Choose Hiddenlayer if
- Documented coverage is slightly broader and model supply chain risk is your concern.
- An AI bill of materials and model genealogy are governance artifacts you must produce.
- Scanning 35 plus model formats covers an estate with many model sources.
Choose Zenity if
- Agents, not models, are what you are trying to secure.
- Copilot Studio and Agentforce coverage matches where your agents are built.
- Purpose built for agents beats a model security platform extended toward them.
