flatexDEGIRO AG uses Retarus Email Security to protect its employees’ email inboxes. The online brokerage also employs role-based S/MIME encryption for messages subject to regulatory requirements.
flatexDEGIRO provides trading access to around 50 stock exchanges in Europe, North America and the Asia-Pacific region as well as direct over-the-counter (off-exchange) trading. The brokerage and banking business related to securities trading are handled by flatexDEGIRO Bank AG.
Before switching to Retarus, flatexDEGIRO had been relying on self-managed, GNU/Linux-based mail relays and spam filters. Additional security functions, such as CXO fraud protection and virus protection, were provided by an external security specialist.
Due to the limited scalability of its internal email security infrastructure, flatexDEGIRO was looking for a service provider based in the EU. As far as the requirements catalog and specifications were concerned, scalability, reliability and availability of the various SaaS (Software-as-a-Service) products on offer were considered critical points. In a PoC (proof of concept), Retarus was able to prevail against several competitors.
The most crucial, primary use case for flatexDEGIRO is the channeling of inbound and outbound emails via Retarus’ Secure E-Mail Gateway (SEG). For the financial services provider, effective protection against CxO fraud (business email compromise targeting executives) is of paramount importance.
