Pluto Security Exits Stealth With $42 Million to Tackle AI Security Challenges

Pluto Security emerged from stealth mode with $42 million in total funding to address the growing enterprise security challenges posed by rapid AI tool adoption1

1

. The Tel Aviv-based cybersecurity startup raised an $8.5 million seed round led by TLV Partners, followed by a $34 million Series A led by Jump Capital3

3

. Additional investors include Skinos, founded by Check Point co-founder Shlomo Kramer, Ansa Capital, and angel investors from companies like Armis1

Why Enterprise Security Teams Face New AI-Related Risks

The rapid pace of AI tool adoption within enterprises has created unprecedented security vulnerabilities that traditional cybersecurity solutions struggle to address. Shahar Bahat explained that newly announced AI tools can appear inside companies' environments within just two hours of release1

1

. About 60% of the risks Pluto detects come from tools built by non-developers, with finance departments being the biggest source, followed by marketing and legal teams1

1

.

One alarming example involved a finance employee at a Fortune 500 company who built an application to manage customer information and churn, but left it exposed to the internet1

1

. Bahat noted that in every proof-of-concept engagement, Pluto discovered malicious activity, with some companies experiencing active live attacks during evaluations1

1

. This demonstrates the urgent need for AI-focused cybersecurity solutions that can keep pace with employee innovation while protecting corporate AI environments.

How Pluto's Platform Provides Real-Time Enforcement Without Blocking Innovation

Pluto Security's platform distinguishes itself by monitoring AI agents in real time while allowing employees to continue using and building AI tools. The system connects to endpoint security and device management systems, deploying lightweight AI sensors that gather information including prompts, commands, running processes, permissions, and user activity1

1

. These sensors use hardware-efficient AI models to identify malicious activity without consuming excessive computing resources3

3

.

What sets Pluto apart is its ability to intervene during agent operations by injecting context back into sessions. If an AI agent attempts to gain permissions beyond what a user intended, the system can stop the action or add instructions prompting the agent to ask for confirmation1

1

. The platform monitors AI tools employees use, the skills, extensions, MCP servers, and other components those tools rely on, as well as apps and agents being created1

1

. Companies can customize security policies to regulate specific actions, such as allowing developers to run AI-generated scripts only if they don't interact with sensitive systems3

Building Community Through Plutonium and AI Supply Chain Security

Pluto Security has developed an innovative go-to-market strategy centered around Plutonium, a free AI supply chain security hub powered by proprietary RisksDB2

2

. Launched in April, Plutonium lets anyone check risks associated with publicly available AI skills, connectors, add-ons, and MCP servers before installing them1

1

. The platform provides risk assessment data about more than 4,500 tools and includes an MCP scanner and catalog of verified components3

3

.

Thousands of security professionals now use Plutonium, and the community has become an important source of feedback and prospective customers for Pluto Security1

1

. Bahat revealed that 70% of Pluto's sales pipeline now comes from inbound interest, with hundreds of practitioners using the resource weekly2

2

. Saaya Pal, partner at Jump Capital, highlighted this approach: "Pluto has built a fundamentally different GTM engine for cybersecurity. The clearest example is Plutonium, their AI risk database: there was no good public data on what AI tools are actually doing inside enterprises, so the team built it and gave part of it away"2

.

Enterprise Customers Spanning Multiple Industries Trust Pluto Security

Pluto Security has quickly built a diverse customer base of more than 40 enterprise customers across multiple industries2

2

. Notable clients include Oscar Health, Workato, Sixt, AlphaSense, and several Fortune 500 organizations1

.

The founding team brings deep cybersecurity expertise from Microsoft, Palo Alto Networks, Bridgecrew, and Israel's Unit 82002

2

. Shahar Bahat, a Forbes 30 Under 30 honoree, previously held senior cybersecurity leadership roles at Microsoft and Palo Alto Networks2

2

. Tal Ofer Regev served as vice president of research and development at Palo Alto Networks, managing more than 150 people2

2

. The company currently employs about 40 workers in Israel and the United States4

. The company's research capabilities extend beyond its commercial platform—earlier this month, Pluto researchers uncovered a hacking campaign targeting users of Solidity, a programming language optimized for smart contract projects3

.

Rona Segev, founder and managing partner at TLV Partners, emphasized the importance of Pluto's approach: "As AI transforms the way people work, information security teams need to understand what is truly happening and act precisely, identifying when a risk arises and intervening without blocking innovation. This approach is deeply embedded in the company's DNA, and its growth rate shows how much it addresses a real need"4

4

. The combination of strong investor backing, rapid customer acquisition, and a community-driven approach positions Pluto Security as a significant player in the emerging field of securing enterprise AI tool usage.
