What is Noma Security?
Noma Security covers the AI lifecycle from the data-science supply chain to runtime, with strong momentum in agentic security: it holds Extended conformance in the CSA AARM builder registry — the top tier — and raised a $100M Series B in October 2025. The platform inventories AI assets, secures pipelines (notebooks, MLOps tooling), and monitors agents in production.
Why teams look for Noma Security alternatives
Noma's breadth across supply chain and runtime means teams wanting a single deep layer — just guardrails, or just posture — may find a focused tool simpler to adopt. As a fast-scaling startup, its modules mature at different rates.
GuardionAI
GuardionAI matches Noma at the AARM-relevant layer — inline runtime governance of agent actions — while staying deliberately lightweight: gateway-based deployment with sub-130ms policy decisions, no data-science-pipeline instrumentation required.
Why it's better than Noma Security
sub-130ms guardrails latency • 96.3 F1 on the Prompt Security Leaderboard with 0.02% false positives • 50M+ agent actions protected per month
Lasso Security
A GenAI-first platform focused on protecting LLM interactions, offering a secured gateway, browser integrations, and specialized protection for AI agents via MCP.
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
Noma Security is a good fit for…
- •Organizations securing data-science pipelines and agents together
- •Buyers who want a well-funded, AARM-Extended-conformant vendor
- •Enterprises inventorying sprawling AI estates
Look at alternatives if…
- •Teams needing only inline guardrails
- •Very small stacks without MLOps pipelines
Our verdict
One of the strongest independent full-lifecycle plays, validated by AARM Extended conformance and a $100M Series B. Compare deployment weight against gateway-only runtime options.
