Forrester Email Security & Collaboration Security Wave: Mimecast is a Strong Performer

Mimecast has been recognized as a Strong Performer in The Forrester Wave™: Email, Messaging, and Collaboration Security Solutions, Q2 2025.

We believe this recognition highlights the company's innovative strategy of fusing product advancements with acquisitions to deliver a differentiated Human Risk Management (HRM) solution. Mimecast's ability to provide advanced email and collaboration security while mitigating human risk stands out in the competitive landscape.

According to a recent Forrester blog post by Principal Analyst Jess Burn, "the holistic approach of email, messaging, and collaboration security (EM&CS) is a reflection not only of the way people work but of the threats facing those workers as they communicate and collaborate with customers, partners, and each other. Attackers are shifting their focus to other entry points - leveraging targeted multistep campaigns to include voice and text and exploiting SaaS platforms, internal messaging apps and collaboration tools, and file-sharing environments."

Our key takeaway from Mimecast's placement in the Wave

Recognition for strategy: Mimecast is one of just two vendors to earn the highest scores possible in both the Vision and Roadmap criteria.

Forrester's perspective on Mimecast

According to Forrester, Mimecast is a well-established email security vendor with the backing of Permira, a new CEO, and a spate of strategic acquisitions and associated leadership.

The report highlights that email, messaging, and collaboration security must respond to modern threats, including multi-step attacks that exploit internal messaging platforms, SaaS tools, and text communication.

Forrester's findings also affirm for us that Mimecast provides solutions tailored to mitigate these risks, enhancing how users communicate and collaborate safely.

How Mimecast is advancing Human Risk Management

Highlights of Mimecast's HRM offering include:

• Comprehensive vision: Focused on safeguarding the user workspace while quantifying and addressing user risks.
• Advanced functionality: Enhanced phishing protection, Business Email Compromise (BEC) detection, and brand protection strategies.

• Data Loss Prevention (DLP) excellence: Standout features like misdirected email detection via its advanced social graph technology.

Forrester gave Mimecast the highest possible marks in the Vision and Roadmap criteria, validating for us our progressive move toward HRM and its integration with existing security infrastructures, such as EDR/XDR platforms.

What's next

Forrester rightly points out that messaging security has moved beyond email to include many different collaboration tools used by the modern employee. The report also highlights the human element of breaches that continue to happen despite years of investment in point solutions. Mimecast received the highest ratings possible in the Vision and Roadmap criteria and the launch of our Human Risk Command Center further demonstrates a commitment to mitigating human risk for organizations of all sizes.
