Sherlock Calls vs Zenity
Zenity governs the security of AI agents across your enterprise — a critical capability as agentic AI becomes widespread. Sherlock Calls gives your operations team intelligence about voice calls. Two different problems, both worth solving.
TL;DR — The short answer
- 1
Zenity is a well-recognized enterprise security platform — a Gartner Cool Vendor in 2025 — focused on governing AI agents and defending against prompt injection and data leaks.
- 2
Sherlock Calls is an operational intelligence tool for voice teams: investigating calls, analyzing transcripts, and correlating costs across 15+ providers from Slack.
- 3
These tools solve fundamentally different problems and can coexist in any mature AI operations stack.

Key differences
Why teams switch from Zenity to Sherlock
Call Intelligence vs Agent Security
Sherlock Calls
Sherlock answers operational questions: how much did calls cost this week, which agent had the most failures, what was said on this specific transcript — in plain English from Slack.
Zenity
Zenity answers security questions: are my AI agents behaving safely, are there prompt injection attempts, are agent permissions excessive? It is a governance tool for security teams, not an investigation tool for ops teams.
Voice Provider Coverage vs Cross-Platform Governance
Sherlock Calls
Sherlock natively integrates with 15+ voice and business platforms — Twilio, ElevenLabs, Vapi, Retell, Genesys, Amazon Connect, HubSpot, Datadog — your entire voice stack, no instrumentation needed.
Zenity
Zenity covers AI agents embedded in Salesforce Agentforce, Copilot Studio, AWS Bedrock, and Google Vertex — a different platform set, solving a different set of organizational problems.
Free to Start vs Enterprise Security Engagement
Sherlock Calls

Zenity
Zenity is built for enterprise security teams and requires a custom demo and enterprise procurement. It is the right investment for regulated industries managing AI governance risk — not a self-serve operational tool.
