Pluto Security Raises $42M to Help Enterprises Secure Their AI Agents
Tel Aviv-based Pluto Security has raised $42 million in seed and Series A funding to expand a platform that maps and governs AI agents across corporate networks.
About a fifth of the total came from a seed round led by TLV Partners, with the remainder raised in a Series A investment led by Jump Capital. The Series A also drew contributions from other backers, including Skinos, a fund affiliated with Shlomo Kramer, co-founder of Point Software Technologies Ltd.
Pluto says its platform addresses the difficulty of locating every AI agent running inside a corporate network. Cataloging those agents by hand is often prohibitively time-consuming, and administrators can overlook agents that pose cybersecurity risks. The platform automatically maps agents across employee endpoints, cloud infrastructure and software-as-a-service applications.
For each agent it detects, Pluto collects detailed telemetry: the AI model that powers the agent, the tools it uses to carry out its work, and whether users have added customizations such as plugins, file repositories containing prompts and integrations with external applications. According to TechCrunch, Pluto gathers that information through customers' other cybersecurity tools and through lightweight data collection programs called sensors, which rely on hardware-efficient AI models to identify malicious activity. When an agent attempts a risky action, Pluto sends it a prompt instructing it to stop the workflow.
Companies can define cybersecurity policies to control how Pluto mitigates risk. A software startup, for example, could create a policy permitting developers to run AI-generated scripts only if those scripts do not interact with a sensitive system. Policies can also regulate AI agents' tools and user-created customizations.
Alongside its paid platform, Pluto offers a free service called Plutonium that lets companies check publicly available agent extensions, application connectors and MCP servers for risks before installing them. Plutonium provides data on more than 4,500 such tools.
Cybersecurity research is the company's third focus area. Earlier this month, Pluto's researchers uncovered a hacking campaign that targeted users of Solidity, a programming language optimized for smart contract projects. A smart contract is a transaction processing script that runs on a blockchain.
Pluto reportedly generates more than $2 million in annualized revenue from over 30 enterprise customers, while its free Plutonium service has several thousand users.
Editor's Summary
Pluto Security has raised $42 million across a TLV Partners-led seed round and a Jump Capital-led Series A to expand software that inventories AI agents on corporate networks and blocks risky actions. The company pairs its paid platform with a free tool that vets agent extensions and connectors, and it also funds security research. It reports more than $2 million in annualized revenue from over 30 enterprise customers.
