Mimecast Email Security Abu Dhabi Advanced Protection Beyond Microsoft 365
Email is still the number one entry point for cyberattacks on Abu Dhabi businesses. Phishing links, fake invoices, CEO impersonation emails, and malware attachments land in inboxes every single day — and Microsoft 365’s built-in filters are not built to catch the sophisticated ones. If your business has not added a dedicated email security layer on top of Microsoft 365, you are relying on a tool that was never designed to stop today’s threats.
Why Microsoft 365 Alone Is Not Enough
Microsoft 365 Defender provides a baseline level of email filtering. It catches known spam and basic malware. What it does not catch reliably are targeted phishing attacks, advanced impersonation, weaponised URLs that change after delivery, and zero-day email threats.
Mimecast sits in front of your Microsoft 365 inbox and fills these gaps — scanning every email, every link, and every attachment with purpose-built threat intelligence before it reaches your users.
What Mimecast Protects Against
Phishing and spear phishing
Mimecast scans every inbound link at the moment of click — not just at delivery. If a URL was clean when the email arrived but was later weaponised Mimecast still catches it.
Impersonation and business email compromise
Attackers frequently impersonate senior executives or suppliers. Mimecast checks display names, domain similarity, and sender behavior to flag suspicious messages before they reach staff.
Malicious attachments
All attachments are sandboxed and analyzed before delivery. Suspicious files are held or converted to a safe format while the original is under review.
Internal email threats
Mimecast also monitors internally sent emails — catching compromised accounts that send malicious content to colleagues from within your own domain.

Email Continuity — The Feature Most Businesses Overlook
If your Microsoft 365 environment goes down — due to an outage, cyberattack, or migration issue — Mimecast keeps your email running through its own continuity service. Staff send and receive email through the Mimecast portal with zero interruption.
For businesses where email downtime directly costs money or client relationships, this alone is significant.
DMARC and Email Authentication
A significant number of Abu Dhabi businesses have not correctly configured DMARC, DKIM, and SPF. Without these in place, attackers can spoof your domain — sending emails that appear to come from your company to your own clients and partners.
Mimecast includes DMARC Analyzer, which identifies who is sending email on behalf of your domain, flags authentication gaps, and helps you move towards full DMARC enforcement — protecting your brand and your clients.
Implementation: What to Expect
Deploying Mimecast in an Abu Dhabi business typically involves:
- MX record change to route inbound mail through Mimecast before reaching Microsoft 365
- Outbound routing configuration through Mimecast for outbound scanning
- Policy setup for impersonation protection, attachment handling, and URL scanning
- DMARC configuration review
- Brief staff communication on what changes to expect
For most organizations, full deployment is completed within two to three business days with no email downtime during the transition.
