Executive SummaryUpdated on Mar 29, 2026

Cisco Secure Email and Mimecast Email and Collaboration Threat Protection compete in the email security category. Cisco seems to have the upper hand with its strong integration capabilities and comprehensive security features that outweigh Mimecast's streamlined approach.

Features: Cisco Secure Email offers anti-spam and anti-malware capabilities backed by AMP and threat intelligence. It integrates seamlessly with solutions like IBM QRadar and Active Directory. Mimecast provides URL protection, sandboxing, and robust identity protection, with seamless integration into Microsoft 365.

Room for Improvement: Cisco Secure Email needs a better console performance, a more intuitive user interface, and improved scalability. Mimecast requires a reduction in false positives, a more streamlined administration panel, better API integrations, enhanced identity protection, and improvements in support responsiveness.

Ease of Deployment and Customer Service: Cisco Secure Email supports versatile deployment options, making it complex for small businesses but comes with highly rated technical support. Mimecast, operating mainly on public cloud infrastructure, ensures easier deployment. However, it may lack deployment flexibility, and customer service improvements are noted.

Pricing and ROI: Cisco Secure Email is considered expensive but offers a solid ROI through robust security features and flexible licensing. Mimecast, similarly priced, may not offer as compelling an ROI for organizations already using enhanced security suites like Microsoft's. Both solutions are premium-priced, with protection and reduced downtime justifying the cost.

Cloud security has improved remote access and has reduced costs for smaller client sites

I have used Cloudflare One's Identity-Aware Proxy, and it is quite straightforward from what I have seen so far. The app registration on the Azure side integrates fully into Cloudflare, and I am very satisfied with that part because it is easy to set up. The integration of Cloudflare One's Secure Web Gateway and Zero Trust Network Access works without any issues. That part is pretty automatic, and if you complete the rest of the setup, it comes together by itself with no issues from my side. What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection. The hops get shorter and you get better latency. We have done testing to see if it is better. One thing that we did notice with our proof of concept with our current client is that they have people connecting from the UK. When they used their previous VPN solution, uploading CAD drawings and other files to the server took a long time. They mentioned that it is much quicker on Cloudflare One's solution. I definitely believe that is part of the improved performance, and I am satisfied with that as well. What is nice about Cloudflare One is that it makes the setup easier and also easier to train technicians to maintain it. Compared to legacy systems, we do not need to get fancy firewalls in place that are costly. That is definitely also a cost-saver with Cloudflare One.

Email security has protected financial data and provides clear tracking for every branch message

The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.

Advanced email filtering has blocked massive spam volumes and prevents unauthorized data leaks

Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts. Streamlining this could improve overall usability and security management for users. Reporting is another area needing improvement in Mimecast Advanced Email Security, as the reports provided are not very easy to decipher. With artificial intelligence being integrated into various tools including Mimecast Advanced Email Security, I believe there is potential to enhance functionality, enabling users to ask specific questions and retrieve concise answers instead of overwhelming data. I choose a nine for Mimecast Advanced Email Security because improvements such as better user interface and artificial intelligence integration features would greatly enhance its usability. While no tool is perfect, these adjustments could greatly elevate Mimecast Advanced Email Security's capabilities.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Enables me to work from two locations."

"Cloudflare is by far the most effective solution that I have come across."

"Cloudflare is simple to use."

"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."

"Cloudflare, in my opinion, was easy to implement."

"It will take the blow rather than our applications should an attack occur."

"It's a perfect solution from my perspective; it's easy to understand and easy to configure."

More Cloudflare One pros

"We rely heavily on antivirus protection, email content filtering, and authentication mechanisms to ensure compliance with email security. Regarding phishing attempts, while phishing protection features are crucial, we also emphasize user education as a critical defence. The intelligence services Cisco provides, such as the Cisco Intelligence Center, play a significant role in analyzing and validating threats, including phishing attempts, in our email security practices."

"The advanced phishing protection and the integration with the awareness tool that Cisco has embedded into the solution to bring awareness to the customers about the dangers of phishing attacks and other things that come from email are the most valuable features."

"Cisco Secure Email is part of Cisco's extensive efforts and investments in technology, especially in the realm of cyber security. The product is one among many security solutions offered by Cisco."

"The malicious URL scanning, as well as the anti-malware features, have been really useful for us in our environment."

"The Cisco Email Security Appliance has enabled us to reduce spam by at least 30% compared to our previous solution."

"It is doing its work. It is doing what it was actually designed to do. It has ensured we don't have business email compromises, and it has also ensured that our brand Galaxy is unique all year round."

"It does a great job of preventing spam, malware, and ransomware. I can only go by what people have told me and what I've seen, but I have not seen spam in a year and a half to two years in my own company mailbox. And there are not a lot of catches where it's catching something that should have gotten through, either."

"The tech engineers are very knowledgeable."

More Cisco Secure Email pros

"The security on offer is very good."

"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."

"Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it."

"Email security is the most valuable feature of the solution."

"The reviewer gave Mimecast Email Security a rating of 10 out of 10."

"The solution's performance is good."

"The interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."

"The most valuable feature is the DMARC Analyzer."

More Mimecast Advanced Email Security pros

Cons

"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."

"Our subscription plan for the solution has a limitation of bot signatures."

"The software has automated alerts, but the automated alerts are not available in the mobile app."

"I would like them to include a VPN feature to provide a secure connection to the data center."

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

"The tool should provide on-premise versions. Currently, all versions are cloud-based."

"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."

More Cloudflare One cons

"They can do it better with web links, with the URLs. They have a technology called Outbreak but it doesn't work as well as we would like."

"In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam."

"Typically, in a phishing email, they try to use a name everybody's going to recognize, like the CEO's name or the CFO's name... With this appliance, the way it's designed at the moment, for us to really stop that with any level of confidence, we have to build a dictionary of all the names of the people we want it to check, and all the ways they could be spelled. My name would be in there as Phillip Collins, Phillip D. Collins, Phillip Dean Collins, Phil Collins, Phil D. Collins. There could be eight or 10 variations of my name that we'd have to put in the dictionary. There's no artificial intelligence to say "Phil Collins" could be all these other things, and to stop phishing from coming through in that way."

"We would like to see more options for the customization of content filters."

"They can do it better with web links, with the URLs."

"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."

"Having Cisco Email Security as a standalone solution is not good enough. It needs to be combined with another solution."

"Cisco is already providing a very good environment with the IronPort solution, but there could be some more integration with other products. For instance, an integration with the EDR solution could be there to raise an alert."

More Cisco Secure Email cons

"I'd like to have better support from the product in the future."

"It was not a good experience due to the fact that our main infrastructure had a problem for that entire time."

"The solution should include more AI features instead of Mimecast's more general static configuration tooling."

"The feature that should be included is to remove the block on the encrypted files."

"The product's interface could be improved to be more user-friendly."

"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."

"The interface isn't the best. How everything works on the back end is confusing."

"The detection rates are an area for improvement."

Pricing and Cost Advice

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"The solution is not that expensive."

"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."

"The solution's pricing lacks transparency."

"Cloudflare Zero Trust Platform's pricing is good."

"The prices are slightly expensive."

"Cisco Secure Email is more expensive than other products. I rate it a five out of ten. There are no additional costs. You only need to pay the subscription amounts."

"The licensing was all transferred."

"The pricing for the Cisco Email Security Appliance involves recurring costs for licenses based on the contracted time frame, such as one year, three years, or five years. Renewals are required after the license expires."

"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."

"The pricing is good."

"Cisco Secure Email and the support are priced well. It's not cheap, but there are other solutions that offer less and cost so much. For example, Microsoft is more expensive than Cisco."

"The solution is expensive."

"We were using Proofpoint and then we switched to Cisco... reportability was one of the main reasons we switched, but the biggest one was cost. If you can get an equivalent functionality for a better price it's wise to do so. That's what our primary decision came down to: We could get equivalent functionality at a lower price point."

More Cisco Secure Email pricing and cost advice

"The product has good pricing in terms of return on investment."

"The price of Mimecast Mailbox Continuity is expensive."

"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."

"The product price is moderate. I rate the pricing a five out of ten."

"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."

"The solution is expensive."

"For what it is, the product is overpriced."

"The licensing costs are per-user for the product that you get with them."
