Pluto Security receives $42 million to help companies secure their AI agents

Pluto Security Inc., a provider of artificial intelligence security software, today announced that it has raised $42 million in financing.

The company raised around a fifth of the sum through a seed round led by TLV Partners. The rest came in the form of a Series A investment led by Jump Capital. The latter deal also included contributions from several other backers, including Skinos, a fund affiliated with Point Software Technologies Ltd. co-founder Shlomo Kramer.

Manually identifying every single AI agent on a corporate network is often prohibitively time-consuming. This allows administrators to miss agents that pose a cybersecurity risk. Tel Aviv-based Pluto offers a platform designed to address this challenge. It can automatically assign agents across employee endpoints, cloud infrastructure, and software-as-a-service applications.

The platform collects detailed telemetry data on every agent it detects. Pluto identifies the AI ​​model that powers an agent, the tool it uses to perform its work, and whether users have added customizations. These customizations often come in the form of plugins, file repositories that include prompts, and integrations with external applications.

Accordingly TechCrunchPluto collects agent telemetry using other customer cybersecurity tools. In addition, simple data acquisition programs, so-called sensors, are used. Pluto’s sensors rely on hardware-efficient AI models to detect malicious activity. When an agent attempts to perform a risky action, Pluto sends them a request instructing them to stop the workflow.

Companies can customize the way Pluto mitigates risk by defining cybersecurity policies. For example, a software startup can create a policy that only allows developers to run AI-generated scripts if they do not interact with a sensitive system. It is also possible to regulate the tools and user-created customizations of the AI ​​agents.

Pluto offers its cybersecurity platform along with a free service called Plutonium. It allows organizations to scan publicly available agent extensions, application connectors, and MCP servers for risks before installation. Plutonium provides data on more than 4,500 such tools.

Pluto’s third focus is cybersecurity research. Earlier this month, the company’s researchers revealed 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 annual revenue with over 30 enterprise customers. His free Plutonium service has several thousand users. The company will use the new funding to expand its workforce, improve its commercial offering and fund more cybersecurity research.
