Open Systems provides network and cyber security through a cloud-based Secure Access Service Edge (SASE) platform. It combines SD-WAN, a firewall, a secure web gateway, a cloud access security broker (CASB) and zero trust network access on a single platform with a unified customer portal. The service is delivered as a managed service staffed around the clock, which suits organisations that want to outsource the operation of their network and security rather than run it themselves. The company is headquartered in Zurich, Switzerland.
Open Systems was majority-owned by the private equity firm EQT from 2017. In 2024 Swiss Post agreed to acquire it, and the company continues to operate as a standalone entity with its own brand. Switzerland is not an EU member state but belongs to EFTA, and both the vendor and its new owner are Swiss. The platform is proprietary and not open source. The pages consulted do not state in which countries customer data is processed, so European organisations should ask which regions the platform and the operations centres use.
