Noma Security
An AI and agent security platform for discovery of models, agents, and MCP servers, security posture, red teaming, and runtime protection. Noma raised a $100 million Series B in July 2025.
Security teams that must inventory and control agents and AI tools across SaaS, cloud, and developer environments.
Teams that only need model observability or a privacy redaction library.
Verdict
Noma Security is a good fit for security teams that need to discover, assess, and protect an AI estate of models, agents, and MCP servers. Pricing is enterprise security SaaS and aimed at programs with a real inventory to govern. Buyers who will remediate what the platform finds should evaluate it; it is built for AI estate control, not a single chatbot add-on.

Review Excerpts
Excerpts from public reviews and forum discussions of Noma Security, plus representative buyer views drawn from public information. Paid reviews and pay-for-play sites were excluded.
“Noma helped us, in a systematic way, to detect issues and make them actionable in a way that we had struggled to do on our own.”
“With Noma Security seamlessly deployed across our AI stack, we've gained dramatically increased visibility into all of our AI and ML infra, models, and their associated security and compliance risks.”
“Runtime guardrails on our agent tools gave the security team a control short of turning the agent off.”
Representative buyer view
“AI security is a crowded category, and we could not separate vendors until a hands-on proof of concept.”
Representative buyer view
“The platform assumes a security team that owns discovery and policy, which is heavy for a small ML group.”
