Israeli cybersecurity firm Onyx Security launched with $40 million in funding, highlighting continued investor confidence in Israel's tech sector despite regional conflict. The company has developed a platform to secure and control AI agents, has been in stealth development for over a year, and is already working with multiple Fortune 500 companies.
The funding will be used to expand teams and develop new AI models. The launch coincides with significant activity in Israel's tech sector, including Google's massive acquisition of cybersecurity firm Wiz and an overall increase in startup funding.
Main topics: Onyx Security's launch and funding, its AI security platform, the resilience of Israel's technology sector, and major related industry deals.
Israeli cyber firm Onyx Security officially launched operations on Thursday after securing $40 million in initial funding, signalling continued investor interest in the country's technology sector despite the ongoing U.S.-Israeli war on Iran.
The tech sector, regarded as one of the âlargest in â the world, â accounts for about 20% of GDP, 15% of jobs and more than half of Israeli exports, with cybersecurity becoming a fast-growing segment.
Onyx, which âhas developed a platform to secure and control artificial-intelligence agents, has been in so-called "stealth mode" for the last year-and-a-half, âand said it was already working â with multiple âFortune 500 companies.
"Every enterprise is becoming an agent operator - whether they planned to or not," said â Maxim Bar Kogan, co-founder and CEO of Onyx, who served in Israel's 8200 military intelligence unit.
"Agents are given access to the most critical systems in the enterprise, but what are our guarantees they will not make serious mistakes or get compromised?" he said. "The safe adoption of AI agents requires security from attacks, âas well as ensuring agents don't make critical mistakes."
The funding round was led by venture firms âConviction Partners âand Cyberstarts, as â well as a group of angel investors, Onyx said. The funds, it said, would be used to expand product and engineering âteams as well as develop new AI models.
Alphabet's Google on Wednesday completed its $32 billion purchase of Israeli cyber firm Wiz.
Despite the conflict in Gaza, Israeli tech startups raised some $16 billion in 2025, up from $12.2 billion in 2024.
