# Perimeter 81

Perimeter 81 is an Israeli cloud and network security company that develops secure remote networks, based on the zero trust architecture, for organizations. Its technology replaces legacy security appliances like VPNs and firewalls.
Since 2023, Perimeter 81 has been owned by the American-Israeli multinational cybersecurity company Check Point and renamed to "Harmony SASE."

## History

The company was founded in 2018 by Sagi Gidali and Amit Bareket, founders of SaferVPN which was acquired by J2 Global. The SaferVPN network infrastructure, which was developed over six years, served as the basis for Perimeter 81's initial product development.
Based in Tel Aviv, Israel, it raised 19.5 million dollars in three funding rounds during 2019–2020, including investments from USA's SonicWall (Francisco Partners), Toba Capital and Israel's Spring Ventures led by Aviv Refuah. In August 2020, two months after raising funds at 100 million dollars valuation, it completed a $40 million Series B financing round at a company valuation of $160 million.
In June 2022 it completed a Series C financing round led by the USA's B Capital, with the participation of Insight Partners, Entree Capital, Toba Capital and ION Crossover Ventures. It has raised $100 million, at a $1b valuation, becoming a unicorn. The company has over 2,500 clients, among them Fortune 500 companies, as well as small and medium-sized enterprises.
In August 2023, it was reported that the company would be acquired for $490 million by Check Point. The following month, the American-Israeli cybersecurity company announced that it had completed the purchase of Perimeter 81.
