How Safe Cascade works

Our security systems are located upstream of your email server and check all incoming emails for spam, viruses and other harmful codes. Harmful emails are blocked, while all harmless emails are forwarded directly to your email server and delivered as usual. 
Safe Cascade works with almost any SMTP email server. 
Once an email has been accepted by the email server, it can only be deleted by the recipient themselves, meaning that, for many businesses, junk folders or quarantine mailboxes that are full to bursting are an everyday occurrence. Using the methods we have developed and global outbreak monitoring for new waves of spam and viruses, we can detect most spam emails even before they reach the email server and can reject them immediately. Additional filter levels are then used to identify emails that are less likely to be spam. They can be filtered into a special mailbox as usual. However, most of our customers opt out of this, as the ‘remaining spam’ can quickly be deleted from their inbox. 
The probability of an email being wrongfully rejected is 1:1,000,000. In this case, the sender receives an error message and can send the message again once they have been classified as trustworthy. Unlike traditional spam filters, we do not lose any important emails to your spam folder, where they may accidentally be deleted. 
For reliable virus protection, we combine the strengths of at least three virus scanners from leading manufacturers to achieve a detection rate of 100% for known viruses. We identify and block many new threats still without any virus signatures using behavioural analyses and global outbreak monitoring. 

Tamper-proof email archiving

In addition to our spam and virus protection, you can also archive all your email communications with us in a way that is tamper-proof. This is done by automatically creating a copy of all incoming and outgoing emails that is then saved securely and in an unalterable form on our protected systems with the option of being accessed again at any time.    Users can use a web portal to retrieve emails using a full text search or targeted search parameters and have them sent again as needed. Our service meets all legal requirements. We save your emails redundantly in high-availability data centres in Germany.
