Lasso Security vs Zenity

Lasso Security provides an AI Security Platform that delivers visibility, control, and protection across AI models, agents, and applications for enterprises. The platform inventories AI assets including agents, models, prompts, tools, and guardrails via discovery and AI-BOM features. It offers AI Security Posture Management for misconfigurations, supply chain risks, and alignment with NIST and OWASP frameworks. Automated red teaming uses a library of over 3,000 attacks covering OWASP Top 10 and agentic threats like context poisoning. Runtime enforcement provides zero-latency decisions with remediation guidance, while AI Detection & Response leverages MITRE and OWASP for threat detection with 98.6% accuracy and sub-50ms latency, including intent analysis for anomalies. Lasso targets enterprises adopting GenAI, particularly regulated sectors, enabling secure innovation through real-time risk reduction, governance, and compliance support. The platform maps to frameworks like NIST AI RMF, EU AI Act, and ISO/IEC 42001 via runtime policies and audit trails, integrating with tools like Cloudflare and Palo Alto Networks.

Zenity is a security and governance platform for AI agents: agents inside SaaS tools, agents built in-house on cloud AI platforms, and coding and personal agents on employee devices. It was co-founded by Ben Kliger (CEO) and Michael Bargury (CTO). It launched in April 2021 as a security platform for low-code/no-code development, added support for enterprise AI copilots in November 2023 and now focuses on agents. Research and development is in Tel Aviv, and go-to-market and operations are led from New York. Zenity says it has more than 230 employees. Its company page lists a $5 million seed round (November 2021), a $16.5 million Series A led by Intel Capital (September 2023), a strategic investment from Microsoft's M12 (July 2024), a $38 million Series B co-led by Third Point Ventures and DTCP (October 2024) and a $125 million Series C led by Norwest (August 2026). Zenity released a new version of its platform in August 2026, organized in three parts. Surface covers AI Observability (an inventory of agents, MCP servers, tools and data access, including agents built without security review), AISPM (configuration and permission checks before agents go live) and Exposure Management (which access paths are actually exploitable). Enforce covers Runtime Boundaries, which checks each agent action in real time and allows it, blocks it or shuts the agent down, including multi-step chains such as data exfiltration or privilege escalation; Agentic Identity, which gates actions on the identity an agent acts for in Okta or Microsoft Entra ID; and MCP Security, a gateway that allows, modifies or blocks tool calls and flags tool poisoning, rug pulls, shadow servers and over-scoped servers. Protect is AIDR, which detects direct and indirect prompt injection, data exfiltration, tool misuse and memory poisoning with LLM-based intent detection. Zenity names Microsoft 365 Copilot, Copilot Studio, Power Platform, ChatGPT Enterprise, Claude Enterprise, Salesforce Agentforce, ServiceNow, Amazon Bedrock and AgentCore, Google Vertex AI and Microsoft Foundry among the platforms it covers. For coding agents such as Cursor, Claude Code, Codex and GitHub Copilot, it collects activity through native agent hooks and OpenTelemetry and enforces policy through its MCP gateway. It sends agent findings to AWS Security Hub (in OCSF format) and to ServiceNow SecOps. **AI compliance coverage** Zenity maps its detections to the OWASP LLM Top 10 and MITRE ATLAS. We found no mapping on its site to the EU AI Act, the NIST AI RMF or ISO 42001. Its trust center says Zenity holds SOC 2 Type II and is ISO 27001 compliant and ISO 27701 compliant; reports are available on request. **Who it's for** Large enterprises running many agents across Microsoft, Salesforce, ServiceNow and OpenAI platforms, plus homegrown and coding agents, that want one policy layer over all of them. Zenity says most of its customers are Fortune 500 or Global 2000 companies; SoftBank Corp. is the only one named, in its Series C announcement. Gartner named Zenity a Cool Vendor in Agentic AI TRiSM (September 2025), and Zenity quotes an April 2026 Gartner report calling it the company to beat in AI agent governance.
