6 ways Mimecast protects email in Microsoft 365

Email remains one of the most vulnerable entry points for cyberattacks, with over 90% of breaches beginning in the inbox. Business email compromise (BEC) alone has cost businesses over $43 billion globally since 2016. With Microsoft 365 expected to reach 500 million daily users by 2025, its immense popularity makes it a prime target for attackers. 

While M365 simplifies collaboration for businesses, it also creates opportunities for cybercriminals to:

1. Exploit trust by impersonating Microsoft (600M identity attacks on Microsoft 365 each day)
2. Gain access to tenants for reconnaissance purposes
3. Launch new attacks at scale

Uniform security controls, which attackers can study and exploit, cannot provide the necessary protection in today’s threat landscape.

How Mimecast protects your email in Microsoft 365 

To counter threats and reduce operational risks, businesses need protection beyond Microsoft’s native capabilities. Mimecast provides a comprehensive solution to strengthen email security with enhanced detection efficacy, seamless integration, simplified administration tools, and robust intelligence sharing. By complementing M365 with Mimecast, organizations can proactively defend against advanced email threats while maximizing their existing technology investments in the following six ways: 

1. Measurably improved email security efficacy 

Relying solely on Microsoft’s built-in email security leaves your organization vulnerable to advanced, targeted attacks. Mimecast’s multi-layered detection uses AI-powered tools like URL rewriting, natural language processing, and full emulation sandboxing to protect against phishing, BEC, and malware attacks. This layered approach drastically reduces risks, providing unmatched protection across all emails. 

2. Simplified administration for better efficiency 

Managing email security shouldn't be overly complex. Mimecast prioritizes ease of use with an intuitive interface, real-time threat remediation, and granular policy controls. IT teams can quickly create, update, and enforce security policies, saving time and resources to focus on strategic goals. 

3. Complementary capabilities that add seamless value 

Native Microsoft 365 security often struggles with platform latency, immature policy architectures, and a lack of holistic threat protection. Mimecast’s 100% cloud-based solution works harmoniously with Microsoft, ensuring operational efficiency and streamlined deployment for businesses, regardless of their M365 licensing tier. 

4. A smarter security ecosystem 

Disjointed tools can create visibility gaps, leaving organizations vulnerable. Mimecast eliminates silos by integrating with over 350 security technologies, including Microsoft Sentinel SIEM. Centralized threat intelligence and streamlined log management improve detection and response, enhancing security across your organization. 

5. Faster ROI and cost efficiency 

While Microsoft’s bundled pricing may seem cost-effective, hidden expenses arise when gaps in its native security require third-party tools. Mimecast delivers a proven 255% ROI over three years by enhancing email security efficacy and ensuring businesses maximize their M365 investment. 

6. Comprehensive Human Risk Management 

Microsoft’s security often falls short in addressing human risk, leaving admins and users exposed to social engineering, phishing, and insider threats. Mimecast goes beyond filling gaps by providing user awareness training, insider risk management, and advanced compliance tools to protect employees and empower smarter decision-making. 

Strengthen your Microsoft 365 email security 

Email continues to be the #1 threat vector. Mimecast’s AI-driven solutions provide the layered security M365 users need to stay protected, efficient, and resilient. Avoid over-reliance on bundled solutions and take control of your security future.
