Email, fax, SMS, and EDI are the key channels for business communication. The exchange of information must not only rely on state-of-the-art technology, but it must also be able to continuously fulfill greater requirements in terms of security, compliance, and profitability. It takes a lot of experience to steer information flows at this level. And companies also need a global infrastructure with highly available data centers, state-of-the-art technologies, and innovative cloud messaging services. In short, an international turnstile for information flows. This is what we call the Retarus Global Delivery Network.
