Email is your digital nervous system.
And your Achilles’ heel.
Email is an integral part of every digital workplace. It is also used to manage business-critical processes.
But email today isn’t as simple as it once was. Gone are the easy days of Simple Mail Transfer Protocol (SMTP). Instead, we have to deal with globally distributed, heterogeneous, and sometimes antiquated system landscapes. Often, workplace traffic and application traffic are one and the same. Cyber criminals are smarter and more targeted in their attacks. Emails continue to grow in complexity and their susceptibility to errors. What are the consequences? We see system malfunctions and costly process disruptions, even total operational failure.
Leave all of these problems behind and create real added value for your business with the Secure Email Platform from Retarus: the only cloud-based complete solution for email.
