USP Secure Entry Server (SES) is a product suite from United Security Providers AG for protecting web applications and APIs. According to the vendor, it combines a web application firewall (SES WAF), authentication with single sign-on and strong authentication (SES Authenticate), and identity management with federation (SES Identity). The WAF uses a hybrid security model that includes the OWASP Core Rule Set with auto-learning, anomaly detection, protection against denial-of-service attacks and API protection.
United Security Providers AG is headquartered in Bern, Switzerland. Switzerland is not an EU member state but an EFTA country with an EU adequacy decision. SES is installed and operated by the customer, on-premises, in a hybrid setup or in containers such as OpenShift. Your traffic and logs then stay on your own infrastructure and are not hosted by the vendor. The same company's separate sorbay cloud offering names Swiss data centres. The pages consulted say nothing about ownership or a parent company, so ask the vendor during procurement.
