Overview
Open Systems SASE is a managed secure access service edge (SASE) offering from Open Systems AG in Zurich. It combines SD-WAN, firewalling, a cloud secure web gateway, a cloud access security broker (CASB), zero trust network access (ZTNA) and a managed email security gateway, plus an optional managed network underlay built on regional last-mile connectivity, a private backbone and global points of presence. Each service consists of edge devices and/or cloud components, a customer portal and 24x7 operation by Open Systems’ Mission Control engineers. Customers can choose a fully managed or a co-managed model.
The service is aimed at companies and organisations, including manufacturers and NGOs; Open Systems states that its customers operate in more than 180 countries. It is neither self-hostable nor sold as a self-service product, and prices are not published. Swiss hosting is listed as available, but because traffic is handled at edge devices and points of presence worldwide, not all processing takes place in Switzerland. No security certifications could be confirmed from accessible sources.
Open Systems was founded in Zurich in 1990. The private equity firm EQT held a majority stake from 2017 until Swiss Post acquired the company in October 2024; it continues to operate under its own brand within the Swiss Post group.

Swiss footprint
Five independent questions. A Swiss company is not automatically Swiss-hosted — and vice versa. How the footprint is assessed
Swiss native. Swiss-headquartered, Swiss-owned company; product developed (wholly or largely) in Switzerland.
- HeadquartersIs the operating company headquartered in Switzerland?
- Zürich, Zurich (ZH), SwitzerlandVerified[1]
- Legal jurisdiction
- OwnershipIs the company ultimately Swiss-owned?
- Yes — Die Schweizerische Post AG (Swiss Post) · SwitzerlandVerified[3]
Swiss Post announced in 2024 that it would buy Open Systems from the private equity firm EQT, majority owner since 2017; Open Systems states that the acquisition closed on 21 October 2024 and that the company continues to operate under its own brand. Trade press in 2026 still describes Open Systems as part of Swiss Post, and the board was replaced in November 2024. Swiss Post is owned by the Swiss Confederation. Open Systems' former managed detection and response business had been split off as Ontinue, which stayed with EQT.
