Mimecast Advanced Email Security and Sophos Email are both prominent products in the email security category. While Mimecast is noted for its superior feature set, Sophos is recognized for its aggressive pricing and integration capabilities.
Features: Mimecast Advanced Email Security includes sandboxing, anti-spam capabilities, and URL and attachment protection. It integrates seamlessly with Microsoft 365 and offers comprehensive reporting tools. Sophos Email integrates with Office 365 and Google Workspace, featuring spam protection, phishing protection enhanced by AI capabilities, and provides a simple management interface for efficient use.
Room for Improvement: Mimecast users have noted the need for a more efficient way to submit phishing emails collectively, better customer support, and improvements in the admin interface. They also report ongoing service disruptions and issues with outgoing mail blocking. Sophos Email users suggest enhancements in spam filtering, improved AI for detection accuracy, and pricing flexibility. There is also a need for better compatibility with existing systems and third-party tool integration.
Ease of Deployment and Customer Service: Mimecast Advanced Email Security, primarily cloud-based, is praised for its integration capabilities but has issues with support response time and dependency on a knowledge base. Sophos Email offers versatile deployment across cloud and on-premise environments and receives positive feedback for responsive technical support. Both solutions offer hybrid cloud deployment options but vary in support interaction frequency.
Pricing and ROI: Mimecast is known as an expensive option with a complex pricing structure, charging per user and requiring additional fees for support. In contrast, Sophos Email has a reasonable pricing structure but is slightly higher than desired by some users. Mimecast provides a good return on investment due to its feature set, while Sophos is appreciated for its competitive pricing and comprehensive security capabilities.
There is definitely a return on investment when using Mimecast, as it blocks phishing emails, reducing the risk of significant financial losses.

Overall, my experience with pricing, setup costs, and licensing was smooth.
Sophos Email pricing is a bit high, especially since I purchase through a partner, and they sell it at a higher price since they also seek to make a profit.
There was a signature phishing scam on the internet, but Mimecast Advanced Email Security caught it before it came to fruition and instantly blocked that signature-based phishing scam.
It easily generates reports about the kinds of emails coming in weekly and classifies them into various categories, making it very helpful to analyze and ensure our email gateway remains safe and secure by updating all security patches.
A distinct advantage of Mimecast is its ability to block phishing and impostor attacks, which are significant threats currently.
It provides a defense layer for email protection, scanning every incoming and outbound email for malware and spam.
Sophos already has Sandbox, and if any issues are identified, Sophos blocks that particular mail and site instantly, which is why customers are very happy and safe from other attacks.
XDR stands for extended detection and response, and it's a technology where the system automatically exchanges security signals between the endpoint, the email, and other similar products of the same brand.
