“We’re doing for identity what Wiz did for cloud”: Linx Security raises $50 million Series B
The Israeli startup targets the fast-growing identity security market as AI agents and non-human users multiply, adding complexity to how organizations manage access and risk.
Cybersecurity company Linx Security, which has developed an identity security and governance platform, has raised $50 million in a Series B round led by Insight Partners, with participation from existing investors Cyberstarts and Index Ventures. The round brings the company’s total funding to $83 million.
“There are significant shifts underway in the world of identities,” Linx Security CEO Israel Duanis told Calcalist. “We manage all types of identities, including AI agents. These agents increasingly inherit permissions and access rights that were traditionally assigned to humans, and that’s where the market is heading.”
According to Duanis, organizations are rapidly adopting new applications and AI-driven tools, accelerating the pace at which systems are deployed and integrated. “In the past, implementation cycles were slow, allowing time for decision-making. Today, in the AI era, a product can be deployed within hours. Everything is moving much faster,” he said. “Wiz did it for cloud security, Cyera for data, and we are doing it for identity.”
The company says it has seen rapid growth, with revenue increasing tenfold over the past year. “We plan to continue expanding our development and sales teams as we build out our go-to-market engine,” Duanis added. “Our valuation increased significantly in the last round. We are not a unicorn yet, but we are not far from it.”
Linx Security was founded in 2023 by Duanis and Niv Goldenberg, the company’s CPO. The two bring more than 25 years of combined experience in cybersecurity and identity management, including senior roles at Check Point, Microsoft, and Transmit. The company employs around 100 people and serves more than 60 customers, primarily in North America.
The enterprise identity management market, estimated at roughly $50 billion, focuses on controlling and managing access to systems and data within organizations. Many existing solutions were built more than two decades ago for on-premises environments and rely heavily on periodic permission reviews and manual processes.
The shift to cloud computing, alongside the growing number of applications and identities within organizations, including employees, services, and automated systems, has significantly increased complexity. In many cases, non-human identities now outnumber human users.
More recently, AI agents have emerged as a new category of identity, operating within organizational systems and requiring access to data and infrastructure. This development is further complicating how access is managed and secured.
Linx Security’s platform is designed to address this challenge by continuously mapping and managing the identity environment. The system aggregates data from across organizational systems, analyzes relationships between users, identities, and permissions, and enables real-time identification and mitigation of security risks.
