Customizable Email Security Policies That Protect Against Many Threats
What do you like best about the product?
It offers a wide range of email security policies with a strong level of customization. We’re able to protect our environment against many different types of threats, including dangerous malware, phishing attacks, impersonation attacks, and more.
What do you dislike about the product?
The interface isn’t very intuitive, and it can be a bit difficult to navigate through all of the policies and find exactly what I need. Customer support has been hit or miss as well. Sometimes I get good support, but other times it’s been difficult and lengthy to get my issues resolved.
What problems is the product solving and how is that benefiting you?
It solves my email security needs. I require a strong security platform to protect me from spam and phishing attacks, and this helps with that.
Email security has protected critical communication but hyperlink handling still needs improvement
What is our primary use case?
How has it helped my organization?
Biggest benefit would be filtering everything that is either spam or a threat before reaching users mailboxes.
What is most valuable?
Filtering from threats before emails are reached mailboxes.
URL protection and sandboxing. Potentially dangerous links are open in Sandbox rather than in user's web browser further helping with potential threats.
What needs improvement?
Allow modification of potentially dangerous hyperlinks to be converted into either text or image instead of rejecting the message.
For how long have I used the solution?
I have been dealing with Mimecast Web Security for more than five years.
What do I think about the stability of the solution?
Relatively stable with minimum issues. However, there were a few in the past caused a lot of headache.
What do I think about the scalability of the solution?
From what I've seen from the MSP, it seems quite complicated to manage the configuration itself, but since I am not using the product as an admin, I can't answer it definitively.
How are customer service and support?
I have not dealt directly with Mimecast Web Security's technical support; whenever we have a problem or something needs to be changed, I reach out to my MSP.
How would you rate customer service and support?
What about the implementation team?
I did not purchase Mimecast Web Security through the AWS Marketplace because it goes through my MSP.
What was our ROI?
In general, I can't comment on ROI with Mimecast Web Security since I never worked without mail security application. I can't quantify the time I would need to spend on fixing issues or dealing with threats without Mimecast.
What's my experience with pricing, setup cost, and licensing?
MSP in charge for setup etc. Costing seems similar to other evaluated solutions.
Which other solutions did I evaluate?
Mimecast was chosen by MSP who is also providing full support for us with the product. However, we as a company are evaluating various solutions which can provide better value to us either directly or indirectly via MSP. Mimecast seems to be heavy on configuration rather than using a user behaviour compared to alternatives we were presented.
What other advice do I have?
We have been using Mimecast Web Security for quite a lot of years. Regarding the analytics part you asked and what metrics are most valuable for monitoring web activities in our case, we am not dealing with the monitoring; that's our MSP who does the majority of the monitoring on our behalf.
Regarding the reporting part, I have seen the original reports from Mimecast Web Security, which seem to be quite heavy in terms of information. With the MSP, we are just reviewing and discussing what is necessary. If there is a concern, that is dealt with MSP immediately rather than waiting for formal conversations. However, I think the Mimecast report is fine and easy to read.
It is hard for me to say whether the installation is easy or complex, as I wasn't involved; it was done by our MSP. I am the end customer of Mimecast Web Security, not a consultant.
Email security has protected data and now simplifies archiving and prevention workflows
What is our primary use case?
I have been working with Mimecast Email Security.
What is most valuable?
The functionality, including email archiving and data loss prevention features, is adequate. Mimecast Email Security offers certain features inherent to the product which are beneficial. In case of additional needs, I explore further customization.
What needs improvement?
There is room for improvement since new threats are emerging. Considering the availability of new features would be worthwhile. Mimecast Email Security is somewhat expensive compared to the competition in the Indian market, and the local presence is lacking as they do not have a local representative currently.
For how long have I used the solution?
I have been working with Mimecast Email Security for approximately seven months.
What do I think about the stability of the solution?
Currently, I am not facing any issues with Mimecast Email Security. If something comes up, I will be keen on exploring other products.
What other advice do I have?
I have been satisfied with Mimecast Email Security as a good solution. However, if I need anything additional, I will surely explore what can be done on that. I would rate this product nine out of ten.
Which deployment model are you using for this solution?
On-premises
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)
Robust Email Security Made Simple and Effective
What do you like best about the product?
Mimecast Advanced Email Security stands out for its strong protection against phishing, malware and impersonation attacks while remaining easy to manage. The interface is intuitive, making daily monitoring, policy updates and threat investigation straightforward even for small security teams.
Implementation is smooth and well-documented, with minimal disruption to existing mail flow. Integration with M465 is seamless and features like URL protection, attachment sandboxing and impersonation protection work effectively out of box.

Mimecast Advanced Email Security addresses critical email-based threats such as phishing, spear- phishing, malware, ransomware and business email compromise.

Mimecast, a Great Mail security tool
What do you like best about the product?
The features that stand out most are its Targeted Threat Protection, and the ease of use it provides. The TTP suite is excellent at neutralizing most attacks, including Impersonation Protection which accurately flags and blocks Business Email Compromise and CEO fraud attempts that traditional filters miss.
What do you dislike about the product?
At times, the Administration user interface tends to be slow and unresponsive, which can be frustrating.
What problems is the product solving and how is that benefiting you?
Targeted Threat Protection: Features like Impersonation Protection and advanced AI/machine learning stop social engineering attacks that manipulate employees. This directly translates to reduced financial loss and prevented breaches from wire transfer fraud or credential theft
Consistent, Low-Noise Phishing Protection with Smart Features
What do you like best about the product?
Consistent, low‑noise protection from phishing and impersonation—smart URL rewriting and attachment sandboxing with clear reporting and simple policy control.
What do you dislike about the product?
URL rewriting can break links, the admin UI/reporting feel clunky with limited customization, and quarantine workflows sometimes delay legitimate mail.
What problems is the product solving and how is that benefiting you?
It closes the biggest email gaps—phishing/BEC, spoofing, and malware in links/attachments—by filtering and detecting impersonation before messages reach users. The result is fewer incidents and account takeovers, less SOC/helpdesk noise, faster investigations via centralized reporting/quarantine, better compliance posture, and more confident users.
Great when we started with them, declined quickly after implementation
What do you like best about the product?
Included email signatures in their offering for free as well as the tabbed interface made switching between consoles very easy!
What do you dislike about the product?
The product was 'ok' but not the best at catching everything. The real reason for the decline was in support. Getting customer service on the phone during outages was horrible and took entirely too long in a SEV-A scenario.
What problems is the product solving and how is that benefiting you?
They did an ok job at first at protecting us from threats, however as the time went on it seemed like they were always a step behind the competitors in this space.
Experience high detection and user-friendly policies with reliable email security implementation
What is our primary use case?
My use case for Mimecast Email Security is that it's one of the best solutions for a traditional gateway. Check Point is the best for the AI-based solution. We are selling both as a partner for both solutions to customers.
What is most valuable?
Mimecast Email Security includes the best gateway solution across all Cisco, Trend Micro, and other solutions. For customers who want a traditional gateway, we suggest using Mimecast Email Security. For customers who want the advanced solution, we suggest Check Point for those features.
Mimecast Email Security's anti-phishing features are good and perform as expected.
Mimecast Email Security is a good solution because our customers haven't reported any phishing emails being delivered. It performs effectively as a traditional gateway solution. We haven't received any complaints regarding this solution.
What needs improvement?
Mimecast Email Security can be improved by adding some API integrations. Instead of remaining a traditional gateway, Mimecast Email Security needs to provide API solutions similar to Check Point.
For how long have I used the solution?
I have been working with Mimecast Email Security for almost two years.
What was my experience with deployment of the solution?
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.
What do I think about the stability of the solution?
Mimecast Email Security is a stable solution. We don't encounter many issues with it. Customers report issues rarely, once or twice a month at most. It's performing well, and customers aren't reporting significant problems after implementation. They confirm it's a good solution where only one or two rare emails get through, while the rest are properly blocked without any issues.
What do I think about the scalability of the solution?
Mimecast Email Security is a scalable solution. If Mimecast Email Security introduces API solutions, it will dominate the market. This would also be beneficial for Check Point.
How are customer service and support?
I would rate my experience with technical support of Mimecast Email Security between seven and eight out of ten for their support.
How would you rate customer service and support?
Neutral
How was the initial setup?
The initial setup of Mimecast Email Security was easy, though it's not user-friendly.
What about the implementation team?
My relationship with Mimecast Email Security is as a partner.
What other advice do I have?
I am not familiar with the pricing details of Mimecast Email Security as I am an engineer. The sales team manages all pricing-related matters.
Most customers are using Mimecast Email Security in the cloud only, not on-premises.
Mimecast Email Security has a high catch rate compared to other solutions such as Cisco, Trend Micro, or Barracuda. They consistently implement new solutions and inform all their customers and partners about new features, which is a positive aspect.
Based on overall experience, Mimecast Email Security is the best solution for traditional gateways. Having worked with multiple traditional gateways including Cisco, Trend Micro, and Barracuda, Mimecast Email Security stands out as the superior option.
On a scale of 1-10, I rate Mimecast Email Security a 10 overall.
