Frequently Asked Questions about 365 Mail Protection

  • How does 365 Mail Protection secure email traffic?

    365 Mail Protection is an email security gateway. This means it is positioned in front of your Microsoft Exchange Online mailboxes. It filters out unwanted emails at the earliest possible stage. Unwanted emails include spam as well as all types of fraudulent emails containing dangerous email attachments, viruses, and links to phishing or malware sites.

  • It is a cloud solution. How is data protection ensured?

    As a German company based in Bochum, we are bound by strict German data protection laws. The servers used to scan emails are located exclusively in Germany. They are operated by our partner, the German cloud provider IONOS. High reliability and the protection of customer data against unauthorized access are our top priorities and those of IONOS. Scanned files and content are never stored in the cloud.

  • Who can I call if I need help?

    If you have any questions about your Mail Gateway, our team at our headquarters in Bochum (Germany) is here for you. 24/7, 365 days a year.

  • We have endpoint security, so why invest in email security?

    With Microsoft 365, all you need is a browser to access business emails. Employees can therefore also access it from a cell phone or personal computer on which no endpoint security is installed. If they then click on a phishing link, your company’s sensitive data or passwords are stolen. This is exactly what an email security gateway prevents: dangerous emails never reach the inboxes in the first place – no matter which device they are accessed on. This way, you can rely on seamless protection.

  • What are the system requirements for 365 Mail Protection?

    You can use 365 Mail Protection if the email domain you want to protect runs on Microsoft 365 Exchange Online or the standalone Exchange Online solution. You’ll need admin access there.

    If you run your own Microsoft Exchange Server, you can protect yourself with our G DATA Exchange Mail Security.

  • In which languages is 365 Mail Protection available?

    Our email security gateway is available in German and English.

  • How can I use 365 Mail Protection?

    You can combine our secure mail gateway with our Managed XDR Service or our Endpoint Security. The benefit for you: In both cases, 365 Mail Protection is directly integrated into your familiar dashboard. Alternatively, you can purchase our mail security as a standalone solution.
