Executive SummaryUpdated on Feb 4, 2026

Mimecast Advanced Email Security and Sophos Email Protection compete in the email security sector. Mimecast takes the upper hand with its advanced sandboxing and threat intelligence capabilities, while Sophos appeals with its affordability and comprehensive feature set.

Features: Mimecast offers extensive sandboxing to analyze and filter threats, detailed threat protection, and seamless Microsoft 365 integration. It is known for user-friendly administration and effective archiving services. Sophos provides strong spam and phishing protection, excellent cloud platform integration, and AI-driven email analysis, delivering proactive threat coverage.

Room for Improvement: Mimecast users report high detection rates and inadequate reporting functionality, with a support model that relies heavily on articles, which some find lacking. The cost for data extraction is also a concern. Sophos faces challenges with detailed filtering, inadequate customer service in weak connection scenarios, and frequent price hikes affecting satisfaction.

Ease of Deployment and Customer Service: Mimecast offers versatility across various setups, but its support is overly dependent on documentation, leading to slower responses. The hybrid cloud model is flexible, aiding deployment. Sophos provides seamless installation in multiple environments and consistent customer service feedback, keeping deployment straightforward.

Pricing and ROI: Mimecast's premium pricing offers substantial ROI through threat protection, although it may be considered expensive. Sophos, generally priced lower, experiences yearly price increases but remains a cost-effective solution. It is praised for affordable subscriptions and valuable protection features, delivering satisfactory ROI.

Experience high detection and user-friendly policies with reliable email security implementation

The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Stronger email and mobile security has protected users from ransomware and simplified management

Price is obviously a challenging part, and I think it is the biggest problem we have suffered from over the last two or three years due to a 7 to 8% hike per year, twice a year, which is why we have some renewals on Sophos Email, Sophos XDR, EDR, and the firewall, but due to price hike, they are unable to renew it. The price is going to be very high. It would be better if Sophos can provide a more flexible pricing model for different types of businesses. Price could be lower. The main competitor for Sophos in the market is Palo Alto, which has reduced their price by more than 35 to 40%, making it a very challenging part to sell this product. Palo Alto provides the same functionality for email security, which adds to the challenge because the price is going very high.
