Bold raises $28 million Series A to make endpoints smarter and safer

The Israeli startup transforms computers into active AI security agents running real-time risk analysis. 

Cybersecurity company Bold Security has raisd $28 million in a Series A funding round. The round saw participation from Bessemer Venture Partners, Picture Capital, and Red Dot Ventures. To date, the company has raised a total of $40 million, including a $12 million Seed round in 2024. That round was led by Bessemer Venture Partners and Picture Capital, with additional contributions from Cerca and angel investors such as Wiz founders Assaf Rappaport and Roy Reznik.
Founded in 2024 by Nati Hazut (CEO), Hadar Krasner (CPO), and Omri Mallis (CTO), Bold Security is headquartered in Tel Aviv, where it currently employs 24 people. Following the latest funding, the company expects to double its workforce by the end of 2026. Hazut previously founded SAM Seamless Network, where he worked with Mallis, who was the company’s first employee. Hazut later founded Polyrize, a cloud data security and authorization company that Krasner joined as CPO. Polyrize was subsequently acquired by Varonis.

In recent years, end users have gained greater freedom and capabilities, partly due to the integration of AI tools into organizational workflows. Traditional security approaches, which rely on multiple legacy solutions, have struggled to address emerging risks. Many endpoint security solutions still perform activity analysis in the cloud. Bold Security’s platform, however, runs AI models directly on the endpoint. Each computer performs local security analysis in real time, understands how users and AI tools operate, and responds immediately to actions that may endanger the organization.
This approach enables real-time protection, reduces dependency on cloud infrastructure and associated costs, and preserves user and organizational privacy. It transforms the endpoint from a passive layer into an active and intelligent security layer that operates independently. The platform functions as an Enterprise AI Agent, identifying risks as they occur rather than after the fact.
“For years, the endpoint was the industry’s biggest blind spot. A decade ago, we assumed everything would consolidate in the cloud, and the problem would solve itself,” said Nati Hazut, co-founder and CEO of Bold. “The AI boom didn’t just challenge that assumption, it completely reversed it. AI has opened up significant new security gaps, but it has also created the path to solving them. That’s what led us to start Bold, and what continues to drive how we’re building the company.”
