Network access security startup Portnox on Tuesday announced the closing of a $37.5 million Series B round led by Updata Partners, bringing its total funding to $60 million. 

The Texas company, which has roots in Israel, said the new investment lands amidst solid tracking for its cloud-native network access control platform that helps organizations to replace on-prem NAC with cloud-native zero trust solutions.

The company’s flagship product, called Portknox Cloud, is described as a cloud-native platform that unifies passwordless authentication, zero trust access control, risk mitigation, and compliance enforcement for networks, applications, and infrastructures.

Portknox said the product enables organizations  to centrally manage user and endpoint authentication, authorization and risk mitigation policies across all IT assets.

The company said the plan is to leverage its unified approach to help security teams manage access across multiple sites with automated enforcement.

Portknox said it has secured a customer base of nearly 1,000 mid-market and enterprise companies looking to eliminate the need for any on-premises footprint common among traditional information security systems.
