Email remains the primary gateway for cyberattacks, but today’s Business Email Compromise (BEC) attacks have evolved beyond what traditional security tools and even AI can reliably detect. Here’s why organizations need a more comprehensive approach to protect their people, data, and reputation.

For many Middle East organizations, email is the lifeblood of daily business. It connects employees, customers, suppliers and partners, drives financial transactions, and keeps operations moving. Unfortunately, it’s also cybercriminals’ preferred route into your business.

BEC is one of the most damaging forms of cybercrime. Unlike traditional phishing attacks, BEC emails often contain no malicious links or attachments. Instead, they rely on carefully crafted social engineering, impersonation and trust to convince employees to transfer funds, reveal confidential information or approve fraudulent transactions.

As AI becomes increasingly accessible, attackers are using it to create highly convincing emails that mimic writing styles, business relationships, and legitimate communications. The result is that organizations can no longer rely on conventional email filtering, or even on AI in isolation, to stay protected.

AI changing the threat landscape

Artificial intelligence has undoubtedly transformed cybersecurity. Modern AI engines can identify anomalies, detect suspicious behavior, and analyze vast amounts of email traffic far faster than human analysts ever could. However, AI has also become a powerful weapon for attackers.

Cybercriminals are now using generative AI to create convincing phishing campaigns, realistic executive impersonation emails and sophisticated BEC attacks at unprecedented speed and scale. These attacks often bypass traditional indicators that security systems have relied on for years

At the same time, AI-only security platforms present their own challenges. They can generate high volumes of false positives, requiring IT teams to spend valuable time investigating harmless emails. Many also rely on post-delivery remediation—identifying malicious emails only after they have already reached users’ inboxes—creating a dangerous window of opportunity for attackers.

Simply put, AI is an important part of modern email security, but it should never be the only part.

Why Microsoft 365 needs additional protection

Microsoft 365 is the world’s leading business productivity platform, making it an obvious target for cybercriminals.

Many organizations assume Microsoft’s native security provides complete protection. While Microsoft delivers valuable baseline capabilities, today’s attackers actively study and design attacks specifically to evade these defenses. Native security alone can struggle against sophisticated BEC campaigns, QR-code phishing, compromised legitimate accounts and highly targeted impersonation attacks.

Purpose-built email security adds critical layer of defense.

Solutions such as Mimecast complement Microsoft 365 by combining advanced AI with Natural Language Processing (NLP), behavioral analysis, social graphing, computer vision, threat intelligence feeds, reputation analysis, and proprietary detection technologies. Rather than relying on a single detection method, multiple technologies work together to identify attacks before they reach users.

Building a layered & blended defense against BEC

Protecting against BEC requires a comprehensive strategy rather than a single technology. Effective protection should include:

Protecting against BEC requires a comprehensive strategy rather than a single technology. Effective protection should include:

• Advanced AI that analyses communication patterns and identifies anomalies.
• Threat intelligence and proprietary detection engines that validate suspicious behavior rather than relying solely on AI predictions.
• Email authentication protocols including SPF, DKIM and DMARC to prevent domain impersonation.
• Multi-factor authentication to reduce the impact of compromised credentials.
• Security awareness training that helps employees recognize sophisticated social engineering attacks.
• Continuous visibility into threats, user behavior, and emerging risks.

This blended layered approach dramatically reduces the opportunities available to attackers while giving IT teams better visibility and faster response capabilities.

Don’t overlook the human factor!

Technology alone cannot stop every attack. BEC succeeds because it targets people rather than systems. Attackers exploit urgency, trust, and human psychology to persuade employees to take actions they would normally question. That’s why leading security platforms increasingly focus on human risk management. Rather than simply blocking threats, they measure user risk, identify employees who may need additional support, provide targeted awareness training, and continuously strengthen security behaviours across the organization. By combining technology with user education, organizations become significantly more resilient to evolving attack techniques.

Better protection delivers better business outcomes.

The value of comprehensive email security extends well beyond preventing cyberattacks. Independent research referenced by Mimecast shows that organizations combining Mimecast with Microsoft 365 achieve measurable improvements in both security and operational efficiency. Benefits include significantly improved detection rates, simplified administration, enhanced visibility and a reported 255% return on investment over three years, while organizations using Mimecast are less likely to make cyber insurance claims than those relying on Microsoft 365 alone.

For lean IT teams, particularly those supporting growing businesses across the Middle East, these efficiencies free up valuable time to focus on strategic initiatives instead of continually responding to email threats.

Learn how to stay ahead.

As cybercriminals refine their AI-powered attacks, organizations must evolve just as quickly. The most effective defense is no longer choosing between AI or traditional security, it is combining advanced AI with multiple layers of detection, authentication, threat intelligence, and human risk management.

This is what Cobweb MENA and Mimecast will explore during an exclusive webinar this August, where cybersecurity specialists will demonstrate practical strategies for protecting organizations against the latest generation of BEC attacks and explain how a layered security approach can significantly reduce cyber risk.
