Portnox, a provider of cloud-native zero trust access control solutions, has raised $37.5 million in a Series B funding round led by Updata Partners. The new investment will fuel product innovation, expand the company’s market presence, and support security teams with scalable, enterprise-grade access control.

The funding comes as organizations increasingly move away from on-premises Network Access Control (NAC) solutions toward cloud-native zero trust architectures. Portnox’s Unified Access Control (UAC) platform is designed to meet this demand, offering secure access management for all users and devices across distributed IT environments.

As part of the investment, Jon Seeber, General Partner at Updata Partners, joins the Portnox Board of Directors. Updata focuses on high-growth B2B software companies and has completed more than 75 investments and 55 exits. Seeber brings years of experience in tech investment and strategic business development.

Portnox’s flagship offering, Portnox Cloud, integrates passwordless authentication, authorization, risk mitigation, and compliance enforcement into a single, cloud-native platform. It is tailored for organizations with complex infrastructures and aims to simplify access control while maintaining robust security.

The company reports nearly 1,000 global customers, a 95% customer retention rate, and a 4.6-star rating on Gartner Peer Insights. It has also earned industry recognition from SC Media, Cyber Defense Magazine, Cybersecurity Breakthrough Awards, and SC Awards Europe over the past year.

This latest round follows a $22 million Series A led by Elsewhere Partners in 2022, bringing Portnox’s total funding to $59.5 million.
