Founded in 2019, Airgap has focused on providing a zero-trust approach to enabling secure network access and providing network segmentation to stop lateral movement by hackers.

Using an “intelligent” architecture, Airgap’s technology “isolates every device and dynamically controls access based on identity and context, reducing business risk for enterprises with critical infrastructure,” Zscaler said in a statement.


Airgap’s agentless segmentation capabilities will now be integrated with Zscaler’s Zero Trust SD-WAN offering, the company said.

“With Airgap, we further extend Zero Trust Segmentation to deliver visibility and segmentation for east-west traffic on LANs, including critical OT environments,” said Naresh Kumar, vice president of product management at Zscaler, in a blog post.

It’s the second acquisition deal of 2024 for Zscaler, a top provider of SSE (security service edge) and SASE (secure access service edge) technologies. In March, the company announced its acquisition of Avalor, a startup offering a “security-centric data fabric” that will be integrated into the company’s Zero Trust Exchange platform.

Airgap had announced a $13.4 million Series A funding round in April 2022 led by Storm Ventures.
