The challenge

Email is the Most Common Attack Vector for Cyber Crimes

Email is the main method of communication for companies. At the same time, 94% of all malware is spread via email. This makes email the number one attack vector for cyber criminals. The number of email attacks has also increased significantly in recent years. Ransomware attacks in particular, are steadily increasing. Attacks against companies are becoming increasingly sophisticated, not to mention the extortion demands for the release of encrypted data or systems becoming ever higher.

The effects of malware and phishing attacks have become more detrimental for affected companies. They range from massive disruptions of their IT infrastructure to data loss and complete failure of information and production systems.

Interruptions to supply and sales chains lasting several days are not uncommon. In its Risk Barometer, Allianz puts the average cost of cybercrime per affected organization at over 12 million euros.

In addition to the cost of recovery and restoration, this figure also includes consequential costs such as loss of revenue and damage to the organization’s image. Costs that are often incurred due to inadequate email security. That’s why it’s essential to choose comprehensive email protection offered by Retarus’ Cloud Security Services – with their patented, multidimensional defense mechanisms. Because your email is meant to support your business, not put it at risk.

The solution

Email Security Offered by the Retarus Secure Email Platform

Intelligent, Modular, and Protective Components that can be Combined for Maximum Security.

Spam, malware, phishing, business email compromise (BEC) – the attack methods used by cyber criminals are not only diverse. Attackers have become more and more targeted and often combine different methods. As a result, the attacks are becoming more complex and much more difficult for conventional email security solutions to detect. Retarus Secure Email Platform effectively protects your email communications against all kinds of cyber attacks. Intelligent, multi-level defense mechanisms, and patented protective components guarantee perfect cooperation between preventive protection and accelerated response processes. It is especially effective in defending against advanced threats such as ransomware, spear phishing, and CEO fraud, including early detection of previously unknown threats. Maximum control over every incoming and outgoing email is essential for reliable business communication.

That is why the Retarus Secure Email Platform enables you to track the path of every single email through our infrastructure in real time with our admin portal, myEAS, in addition to the detailed reports and comprehensive analyses available. This is data that we can also make available to you via a secure interface for direct integration into your SIEM tools.

Effective Protection from Cyber Attacks with Maximum Flexibility.

Retarus Essential Protection effectively protects your email infrastructure against threats such as malware, spam, phishing, or spoofing. For extended protection, we offer innovative modules as enhancements. They can be added à la carte according to your requirements.

Do you need a higher level of security for your inboxes? With Retarus Advanced Threat Protection, you are optimally equipped against even complex cyber attacks thanks to four parallel virus scanners, Time-of-Click Protection (URL rewriting), and CEO Fraud Detection.

Your email infrastructure can additionally be secured with market-leading sandboxing technology. Suspicious file attachments are executed in a partitioned virtual machine and deleted or quarantined if found.

For maximum protection, Retarus Post Delivery Protection enables subsequent identification of malicious code in emails that have already been delivered. With PZD Real-Time Response, dangerous emails can even be automatically deleted from your users’ inboxes.

Need a connection to your existing SIEM tools? No problem. Forensics SIEM integration delivers events in real-time through a protected interface, allowing you to supplement your data stream with email security details.

Good to know: Retarus’ Email Security Services are the perfect modular enhancement, offering additional protection for standard security components used by Microsoft 365 and Google Workspace.
