Category: Agent & MCP Security
What is Lasso Security?
Lasso Security is a GenAI-first security company covering LLM interactions everywhere they happen: a secured API gateway, browser extension for employee AI use, and — earlier than most competitors — a dedicated MCP gateway that wraps agent-tool traffic with policy and monitoring. It is listed in the CSA AARM builder registry (aligned tier) and positions across both workforce protection and application/agent protection.
Why teams look for Lasso Security alternatives
Covering employees, applications, and agents at once means depth varies by surface: teams with a single acute problem (say, production agent tool-calls) sometimes prefer a vendor whose entire roadmap targets that layer. Lasso is also still a startup — procurement teams comparing it against platform majors weigh vendor risk.
GuardionAI
GuardionAI concentrates entirely on the agent action layer — every tool call and MCP request governed inline with sub-130ms policy decisions, with detection & incident response built around agent behavior rather than split across workforce and app surfaces.
Why it's better than Lasso Security
sub-130ms guardrails latency • 96.3 F1 on the Prompt Security Leaderboard with 0.02% false positives • 50M+ agent actions protected per month
Akto
Designed to protect AI agents and Model Context Protocol (MCP) workflows through automated discovery, red teaming, and guardrails.
Snyk (Invariant Labs)
Snyk acquired Zurich-based Invariant Labs in June 2025, folding the research team that coined 'tool poisoning' and 'MCP rug pulls' into Snyk Labs. Invariant's mcp-scan lineage lives on in the open-source Snyk Agent Scan, detecting 15+ risks across MCP servers and agent skills, and feeds Evo by Snyk, its agentic security orchestration platform launched October 2025.
- Pioneering research credibility (tool poisoning, MCP rug pulls)
- Open-source scanner covering MCP servers and agent skills across IDEs
Runlayer
Enterprise AI control platform combining an MCP gateway, threat detection on every request, shadow-AI discovery, and identity-aware permissions via Okta/Entra. Launched from stealth in November 2025; by mid-2026 customers include Gusto, Instacart, dbt Labs, and PagerDuty. Holds AARM Extended conformance — the highest tier in the CSA registry.
- Strong enterprise traction within months of launch
- Well capitalized ($42M from Felicis and Khosla Ventures)
Lasso Security is a good fit for…

Look at alternatives if…
- •Buyers who need depth on exactly one surface

Our verdict
One of the more complete GenAI-first startups, especially if you want workforce and agent coverage from one vendor. Benchmark its agent-layer depth against pure runtime specialists.
