Perimeter 81

Perimeter 81 was founded in 2018 by Amit Bareket and Sagi Gidali. The company operated in the cloud-based network security space, with a primary product in the Zero Trust Network Access and SASE categories. In September 2023, Check Point Software Technologies acquired Perimeter 81 for $490 million, after which the company's technology and team were folded into Check Point's product portfolio.

Perimeter 81's platform allowed organizations to secure remote access to networks and cloud resources without relying on traditional VPN infrastructure. The product targeted primarily SMBs and mid-market enterprises looking to replace legacy network architectures with a SaaS-based Zero Trust model, with no requirement to deploy physical hardware on-premises.

In the SASE and Zero Trust Network Access market, Perimeter 81 competed against companies including Zscaler, Cloudflare Access, and Cato Networks. The $490 million acquisition by Check Point in 2023 reflected its recognized position in that category. Following the acquisition, Perimeter 81 operates as part of Check Point's SASE division and is no longer sold as a standalone product.
