Detailed Review
Open Systems sells SASE as an operated service. Its descriptions list SD-WAN, a firewall, a secure web gateway, CASB and ZTNA, run by its own team, so the customer buys an outcome instead of assembling products.
The company is Open Systems AG at Raeffelstrasse 29 in Zurich, and its imprint says it belongs to the Swiss Post Group. Its direct website blocked automated access during this review, so the product and hosting statements come from excerpts of its own pages.
Breadth in a managed form
Few European vendors list web gateway, CASB and ZTNA together. The operations team and a named customer success contact are part of the offer, which suits companies without an in-house network security group.
Where the data sits
A vendor blog says Open Systems hosts data in Switzerland or the EU wherever possible, contracts through Swiss or EU legal entities, and can host exclusively in Switzerland on request. The customer contract itself was not available to check.
Swiss law, not EU law
The website terms are under Swiss law. Switzerland is outside the EU, which counts as European for this directory, but Swiss hosting is not covered by EU rules in the same way.
Limitations to Consider
No prices or trial are shown, the managed model means less hands-on control, and the customer contract and hosting terms could not be verified because the vendor site refused automated access. Switzerland is outside the EU.
Who Should Use Open Systems
Companies with several sites that want SASE operated by a European provider, and are comfortable with a quote-based, contract-driven purchase.
