Pluto Security, an Israeli cybersecurity startup founded in 2025, came out of stealth on 13 October 2026 with about $42m in total funding, including a new round of about $34m led by US venture firm Jump Capital.
Skinos Ventures, which Ynetnews links to investor Shlomo Kramer, and AlphaDrive Ventures also took part in the round, which Crypto Briefing describes as a Series A. The earlier seed round was led by TLV Partners with Ansa Capital participating; Crypto Briefing put it at $8.5m. No valuation was disclosed.
Ynetnews and The Jerusalem Post reported the funding on 14 October.

What Pluto Security does
Employees now use AI chat tools, autonomous agents and apps they have built themselves with AI coding tools, often without their security team's knowledge. Pluto's platform monitors this activity on employee devices, assesses the risk in context and applies controls in real time. It is designed to flag malicious extensions, limit unsafe actions by agents and protect sensitive data and credentials.
Chief executive Shahar Bahat told Ynetnews that security has traditionally focused on stopping things, and argued that tools now need to understand what users are trying to achieve. The company also runs Plutonium, a free hub for AI supply-chain security built on its RisksDB database, which hundreds of security professionals use every week, according to The Jerusalem Post.
Customers and traction
Ynetnews reported that Pluto has more than 40 enterprise customers, several of them in the Fortune 500, naming Oscar Health, Workato, Sixt and AlphaSense. Crypto Briefing gave a figure of more than 30. The company says it secures more than 1m endpoints and has reached multimillion-dollar annual recurring revenue; Crypto Briefing put ARR above $2m after sales began in April. These figures come from the company.
Reports on headcount also differ. Ynetnews put the team at more than 50 people, while The Jerusalem Post and Crypto Briefing reported about 40, split between Israel and the US. The Jerusalem Post said most of Pluto's sales opportunities come from organisations that approach it on their own.
The founders and backers
Bahat previously held senior cybersecurity roles at Microsoft. Co-founder Tal Ofer Regev, the chief product officer, was a vice president in a Palo Alto Networks business group, and chief technology officer Gil Maman spent more than six years in technical cybersecurity roles in Israeli military intelligence, according to Ynetnews.
Angel investors named by Ynetnews and The Jerusalem Post include Yevgeny Dibrov, Nadir Izrael, Slavik Markovich, Asaf Ezra, Sharin Fisher Dibrov and Idan Tendler. Saaya Pal, a partner at Jump Capital, told Ynetnews that Pluto had built a different go-to-market engine for cybersecurity, while Rona Segev, co-founder and managing partner of TLV Partners, said the product gives security teams a way to understand what is happening as AI changes how people work.
What the money is for
Pluto plans to use the new funds for product development, cybersecurity research and expansion in the US, where part of its team is already based.
