Frequently Asked Questions

How does Mimecast protect my email from threats?

Mimecast uses multiple layers of protection to keep your email safe. It scans all incoming messages with several detection engines to catch malware, spam, and phishing attempts before they reach your inbox. The system also checks email links in real-time and converts suspicious attachments into safe formats. Their AI-enhanced detection helps spot advanced threats that traditional systems might miss, including targeted attacks that try to impersonate your colleagues or partners.

What happens if my email server goes down?

Don't worry - Mimecast offers email continuity that keeps you working even during outages. If your primary email system fails, Mimecast automatically activates its continuity service. You'll still be able to send, receive, and search for emails through Mimecast's web portal or mobile app. This means no downtime and no missed messages, which is especially important during critical business periods or emergencies.

Can Mimecast work with Microsoft 365?

Yes! Mimecast works great with Microsoft 365 and many other email platforms. The integration is straightforward and adds extra security layers that complement Microsoft's built-in protections. Many companies use Mimecast alongside Microsoft 365 to get more comprehensive threat detection, better archive searching, and added protection against sophisticated attacks. Setup typically takes just a few steps, and your IT team won't need to make major changes to your existing email flow.

How does the URL protection feature work?

When you get an email with links, Mimecast checks each URL at the time you click it, not just when the email arrives. This real-time scanning is crucial because malicious websites often appear safe initially but turn dangerous later. If you click a suspicious link, Mimecast will block access and show you a warning page instead. For links that seem okay but might be risky, the system can display them in a safe, isolated browser so nothing harmful reaches your device.

What training does Mimecast offer to help my employees spot threats?

Mimecast includes training modules that teach your team to recognize and avoid email threats. Their approach uses short, engaging lessons that don't disrupt the workday. The system can even send simulated phishing emails to test employee awareness and provide immediate feedback when someone falls for a test. What's really helpful is that Mimecast can target extra training to specific users who need it most - like those who frequently click on suspicious links or download risky attachments.
