Executive SummaryUpdated on Feb 11, 2026

Mimecast Advanced Email Security and Cloudflare One are two leading solutions in the email security and cloud security market. Mimecast is generally favored for its comprehensive email security features, while Cloudflare One is considered stronger in integration and performance solutions, often seen as providing superior value due to its broad feature set.

Features: Mimecast offers robust email filtering, impersonation protection, and archiving services, noted for sandboxing and smooth integration with Microsoft 365. Cloudflare One integrates multiple security functionalities within a single console, featuring powerful DDoS protection, zero trust network access, and advanced rate limiting tools.

Room for Improvement: Mimecast can enhance customer support responsiveness, simplify its initial setup, and reduce false positives. It also faces challenges with transitioning to other platforms and high data extraction fees. Cloudflare One could benefit from making its initial setup more intuitive and providing better documentation for complex environments, in addition to improving its alert systems and integration with other tools.

Ease of Deployment and Customer Service: Mimecast supports both cloud and on-premises deployment, though users often find the setup complex and desire more onboarding support.

Cloud gateway has strengthened remote web security and now needs better Mac and ISP support

The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

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 Engineer at Logic Infosecurity

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.

Quotes from Members

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

Pros

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."

"It was a very easy product to install. It can be deployed very fast."

"The security aspect of the solution, particularly the malware behind it, is excellent. That's something that really helped us out. It's not just a simple proxy that just blocks the insights of potential threats that come on behind it. They do malware detection and that helps us a lot."

"From a corporate perspective, I understand that it's important to keep the company data safe."

"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."

"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."

"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."

More iboss pros

"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."

"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."

"It is a stable solution."

"Cloudflare DDoS mitigates DDoS attacks."

"Cloudflare is simple to use."

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

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

"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."

More Cloudflare One pros

"I recommend Mimecast based on customer requirements and budget."

"Mimecast is a brilliant product; it works very well, I have very seldomly, if ever, had any problems with it, and it does exactly what it promises to do."

"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."

"The product's most valuable features are impersonation protection and phishing countermeasures."

"Mimecast Mailbox Community is an email gateway required for every organization, regardless of size."

"It does a good job for us, and its admin console is easy to use."

"It is our spam filter, phishing filter, and executive impersonation filter."

"Mimecast certainly helped my customers reduce phishing emails."

More Mimecast Email and Collaboration Threat Protection pros

Cons

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."

"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."

"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."

"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."

"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."

"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."

More iboss cons

"Operating and tuning the product is difficult."

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."

"Our customers no longer use Cloudflare because its service is subpar."

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."

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

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

"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."

More Cloudflare One cons

"As a user, the user interface of the management console could be upgraded, for example."

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

"The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."

"Technical support has been slower than it was in the past, likely due to the pandemic."

"Its pricing can be improved. It is a bit expensive."

"External security features need improvement."

"This solution can be frustrating. It blocks many things that should be going through."

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

Pricing and Cost Advice

"It is expensive compared to one of its competitors."

"The overall pricing for iboss is very competitive and transparent."

"We had the cost of purchasing a new appliance along with the implementation and licensing costs. However, the following year, the cost of just licensing was similar to what was paid the previous year for a new appliance along with the implementation and licensing costs."

"It is not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."

"We have not priced the solution recently, but they were competitive with other vendors in the past."

"It is probably in line with other solutions, but I do not deal with the financial side."

"The solution's pricing lacks transparency."

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

"The solution is not that expensive."

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

"The prices are slightly expensive."

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

"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."

"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."

"It is a bit expensive."

"The customers can select the license packages as per their requirements."

"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."

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

"It's an expensive solution."

"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."

"The solution is expensive."

"I'm always going to say the price needs to be lower, but it's reasonable."
