Noma Security vs Prompt Security

Noma Security is a security and governance platform for AI agents and the wider AI lifecycle. It was founded in 2023 by Niv Braun (CEO) and Alon Tron (CTO), who met in the Israel Defense Forces' 8200 intelligence unit. Its contact page lists a single office, in New York, and its development center is in Tel Aviv. Noma has raised $132 million: a $7 million seed round led by Glilot Capital Partners and a $25 million Series A led by Ballistic Ventures, announced together when it came out of stealth (reported October 31, 2024), and a $100 million Series B led by Evolution Equity Partners in July 2025, with Ballistic and Glilot taking part. Databricks Ventures made an undisclosed investment in June 2025, alongside a partnership with Databricks. The platform has four products. AI-SPM finds agents, MCP servers, skills, models and tools across cloud platforms, SaaS platforms, code repositories and endpoints (through existing EDR or MDM tools), and flags misconfigurations such as excessive agency, unsandboxed agents and secrets in agent instructions. It also scans models from open registries such as Hugging Face for malicious artifacts, hidden instructions and known vulnerabilities, and assesses MCP servers for supply chain risk. Agent Access Control defines which agents are approved, what data they can reach and what actions they can take. AI-DR monitors agent sessions at runtime for prompt injection (including indirect injection through tool responses), data leakage, tool poisoning and scope violations; it can alert, block, mask data inline, steer the agent, require human approval or stop it with a kill switch. AI Red Teaming runs multi-turn attack campaigns against apps and agents, including in CI/CD pipelines, and feeds findings into runtime policies. Policies are enforced through agent hooks, AI and MCP gateways, agent SDKs and APIs. Noma covers SaaS agents built in Microsoft Copilot Studio and Salesforce Agentforce, and homegrown agents on Amazon Bedrock, Azure AI Foundry and Databricks or built with LangChain and CrewAI. Since February 2026 it has been available through the Extended plan of AWS Security Hub, covering Amazon Bedrock and SageMaker workloads. **AI compliance coverage** Noma says its AI-SPM and red-teaming findings map to the NIST AI RMF, the EU AI Act and ISO 42001, as well as the OWASP Top 10 for LLMs and MITRE ATLAS, and its red-teaming product offers these frameworks as compliance presets. A UiPath case study on its site says Noma's scanning supported UiPath's ISO/IEC 42001:2023 certification. We found no published control-by-control mappings. **Who it's for** Large enterprises with many AI agents across endpoints, SaaS and cloud that want one security layer from discovery to runtime. Noma says it is used by more than 10% of the Fortune 100, and testimonials on its site come from people at UiPath, Kantar, Best Buy, Nielsen and Endor Labs.

Prompt Security is an AI security product that controls how employees use AI tools and protects the AI applications and agents companies build. Itamar Golan (CEO) and Lior Drihem (CTO), who had worked at Check Point and Orca Security, founded it in August 2023; it is based in Tel Aviv. It raised $23 million: a $5 million seed round led by Hetz Ventures (January 2024) and an $18 million Series A led by Jump Capital (November 2024), with Ridge Ventures, Okta and F5 joining. SentinelOne, the Mountain View, California security company, agreed to buy Prompt Security on August 5, 2025 and completed the deal on September 5, 2025. Its Form 8-K puts the consideration at approximately $180 million in cash and SentinelOne Class A stock. Prompt Security is still sold under its own name, as part of SentinelOne's Singularity Platform. The product page is on sentinelone.com; prompt.security now hosts research and free tools such as the open-source Prompt Fuzzer, and the old press release we checked there redirects to SentinelOne. **What it does** SentinelOne's Prompt Security page lists three areas. AI Usage Control inventories the AI tools and code assistants employees and developers use, including unsanctioned shadow AI, and redacts sensitive data and enforces policies across more than 15,000 AI services in real time. It also covers GitHub Copilot, Cursor and Claude Code, keeping secrets and intellectual property out of them. AI Application Security tests homegrown AI apps for prompt injection, jailbreaks and data poisoning before deployment, runs a real-time AI firewall, and turns red-team findings into guardrails. Agentic AI Security finds shadow MCP servers and unsanctioned agents, enforces least-privilege access for agents and keeps a searchable audit log. SentinelOne says Prompt's MCP gateway scores the risk of more than 13,000 known MCP servers and can allow, block, filter or redact their actions. Prompt deploys through a lightweight agent and browser extensions, and covers major LLM providers, including OpenAI, Anthropic and Google, and self-hosted models. **Product changes since the acquisition** At its OneCon conference in November 2025 SentinelOne launched Prompt Security for Employees, for AI Code Assistants and for AI Applications, plus Prompt Security for Agentic AI in beta. At RSAC in March 2026 it announced Prompt AI Agent Security, a discovery and governance control plane for agents and MCP servers (agent posture management was in preview), and Prompt AI Red Teaming for testing homegrown AI apps. **Frameworks** Neither SentinelOne's Prompt Security pages nor prompt.security name the EU AI Act, ISO 42001 or the NIST AI RMF; they refer only to meeting compliance requirements in general terms. This profile lists no frameworks. **Who it's for** Companies that want to let employees use generative AI and coding assistants while controlling data exposure, especially existing SentinelOne customers. Named customers include 10x Banking and Carnival Corporation.
