Email Security Dubai

Email Threats Facing Dubai Businesses

Email threats have grown significantly more sophisticated. Modern phishing is AI-generated, personalised, and indistinguishable from legitimate email to an untrained eye. The attacks that cost Dubai businesses the most money are not mass-spam campaigns but targeted, low-volume attacks designed to deceive specific individuals.

• Business Email Compromise (BEC): attacker impersonates the CEO or a supplier and requests an urgent wire transfer or credential reset, with Request a quote average loss per incident
• Spear phishing: personalised email using genuine information from LinkedIn or prior communications to increase credibility
• Malicious attachments: PDFs, Office documents and ZIP files containing macro-based malware or exploit payloads
• URL-based phishing: legitimate-looking login pages for Microsoft 365 or bank portals that harvest credentials
• Account takeover: compromised Microsoft 365 or Google Workspace account used to send internal phishing from a trusted address
• Email spoofing: attacker sends email appearing to come from your own domain, prevented by DMARC

DMARC, SPF and DKIM: Email Authentication Dubai

DMARC (Domain-based Message Authentication, Reporting and Conformance) prevents anyone from sending email that appears to come from your domain, a technique used in both BEC attacks and supplier-impersonation fraud. SPF (Sender Policy Framework) specifies which mail servers are authorised to send email from your domain. DKIM (DomainKeys Identified Mail) adds a cryptographic signature that receiving servers verify. Together, these three DNS-based controls close the spoofing gap entirely when deployed correctly and set to enforcement policy (p=quarantine or p=reject). Most Dubai businesses have SPF configured but DMARC either absent or in p=none (monitoring-only) mode, which provides no protection. We deploy all three and move DMARC to enforcement.

Advanced Anti-Phishing and URL Sandboxing

The default anti-phishing in Microsoft 365 (Exchange Online Protection, included in all M365 plans) catches high-volume, known-bad spam but misses targeted, low-volume phishing, particularly BEC that contains no links or attachments, only social-engineering text. We layer Microsoft Defender for Office 365 Plan 1 or Plan 2 (or equivalent third-party tools) to add: AI-powered impersonation detection that identifies when an email looks like it came from an executive but the sender address differs, Safe Links URL rewriting and sandboxing that checks links at click-time rather than delivery-time (catching links that are legitimate at delivery but redirected later), and Safe Attachments detonation in a cloud sandbox before delivery to the inbox.

Microsoft 365 Email Security Hardening

Microsoft 365 ships with permissive defaults designed to minimise support tickets, not to maximise security. We harden M365 email security by configuring all controls that Microsoft leaves off by default.

• Anti-spoofing protection: enabled and set to quarantine spoofed senders
• Impersonation protection: protect the CEO, CFO and other high-value targets from display-name spoofing
• Safe Links: rewrite all URLs and check at click-time; block malicious links retroactively
• Safe Attachments: sandbox all attachments; block encrypted archives
• Anti-phishing AI: enable mailbox intelligence to detect unusual login patterns
• Conditional Access: MFA enforced for all users; legacy authentication blocked
• Audit log retention: 90-day minimum, required for incident investigation
• Alert policies: admin notified immediately on unusual forwarding rules or mass-delete activity

Phishing Simulation and Awareness Training Dubai

Technology controls reduce the volume of phishing that reaches the inbox but cannot stop a determined, well-crafted attack. The final control is a trained human who recognises phishing and reports it rather than clicking. We run simulated phishing campaigns for Dubai businesses using realistic, current lures (Microsoft 365 password expiry, DHL delivery, DocuSign signature request). Staff who click receive immediate micro-training (30-second module) explaining what they should have noticed. Monthly campaigns with trend reporting show whether click-through rates are improving over time.
