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 blocked sophisticated phishing and now protects inboxes with AI detection
The only challenge with Check Point Email Security (formerly Harmony Email & Collaboration) is that it is an API-based solution. In an API-based solution, the major challenge is that it can read email content and Google Drive content. This presents a data privacy challenge, and we had to mitigate it by signing a Data Processing Agreement and other agreements. Because it is not a traditional in-line solution, Check Point Email Security (formerly Harmony Email & Collaboration) connects with Google Workspace using API permission and can access email, attachments, sender, recipient information, links, and all metadata is with Check Point. Data storage and everything else is with Check Point, which is the challenge. This solution has a drawback because of API deployment, while other solutions are traditional secure email gateways that are in-line solutions. In those solutions, we need to change the MX record, but with this solution we do not need to change the MX record, which is a pro of API-based deployment. However, there is also a con in that with API solutions, the email is scanned but after delivery in the mailbox.

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

"I'm very satisfied with the environment and the dashboard."
"Cloudflare, in my opinion, was easy to implement."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."

"The solution has different options that can be used to differentiate DDoS attacks."
"Cloudflare Access is a stable solution."
"Clover is the best product globally."
"It seems quite scalable. We don't anticipate any scaling issues. We have it deployed in the cloud."
"Its characteristics are adapted to the most modern threats."
"Check Point Harmony Email and Collaboration is the best security software that protects email and collaboration suites in one of the best possible way."
"In terms of technical features, this is the best solution that I have worked with so far."
"It is fast and quite effective in terms of preventing any security incidents."
"Sensitive business data is effectively protected from any third-party attacks that can easily destroy confidential information."
"Check Point Harmony gives us great visibility of the threats we are being exposed to, where they are coming from and what were they targeting, giving visibility of the weak gateways that could lead to an infection or a leakage."
"Check Point has made my threat prevention better; it has helped me avoid having to redo machines and has helped protect our data by not letting unauthorized items through."
"It is our spam filter, phishing filter, and executive impersonation filter."
"It has all the features required for distribution, such as the ability to mail."
"The solution is stable and reliable. There are no bugs or glitches, and it doesn't crash or freeze."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"I have always found Mimecast to be very responsive; for example, if we see something come through, they address it and it helps to sort out the issues."
"I recommend Mimecast based on customer requirements and budget."
"I have been satisfied with Mimecast Email Security as a good solution."
"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."
 

Cons

"Feedback could be enhanced."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"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."
"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."
"The onboarding process can be improved a little bit."
"The response time for support must be reduced."
"They don't have a person to provide support for customers using the solution under their free plan."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"I have learned enough to make the product stable. However, the stability has some challenges."
"if a phishing email were to get through and bypass the product — which very few do — it would be nice if, when a user clicked on that phishing email, they got a second-chance opportunity, a chance to double-check that they really wanted to proceed to that website."
"Maybe Check Point can work on the DLP part."
"There could be more automation features included for it."
"Cloud Guard would be a complete solution if Check Point added a comprehensive data loss solution that included capabilities such as bulk data transfer detection."
"The business team should be further expanded, and more peer feedback should be made available publicly to have better and complete visibility of the application globally."
"Improved support is needed as current support is slow."
"The solution fails to support hybrid deployments."
"They should improve the cookies management feature."
"External security features need improvement."
"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 price could be better, it should be reduced."
"The solution is expensive in comparison to similar solutions."
"The interface isn't the best. How everything works on the back end is confusing."
"Its pricing can be improved. It is a bit expensive."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you about the problem you're reporting."
 

Pricing and Cost Advice

"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 solution is not that 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."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The prices are slightly expensive."
"The solution's pricing lacks transparency."
"Cloudflare Zero Trust Platform's pricing is good."
"Being able to keep the phishing campaigns out of my company has been ROI for me."
"Do a full feature evaluation (interactive) with a support person. That is what I did."
"The price is very good, based on what they deliver."
"Reasonable cost, quick and easy implementation, and transparent."
"The pricing and licensing are always negotiable."
"Cost is the main concern that every customer takes into consideration, and Check Point always negotiates a price that is affordable."
"There are absolutely no additional costs to the standard licensing fees. One of the wonderful pieces is that CloudGuard SaaS is all-inclusive in its licensing. There's no a-la-carte functionality. You're getting 100 percent of the product for the licensing that you're paying."
"I rate the platform’s pricing a seven and a half."
"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 customers can select the license packages as per their requirements."
"The product has good pricing in terms of return on investment."
"The price of Mimecast Mailbox Continuity is expensive."
