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

"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"It is a stable solution."

"Clover is the best product globally."

"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."

"The blocking feature is very good."

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

"I'm very satisfied with the environment and the dashboard."

More Cloudflare One pros

"The main benefit is that hackers can't steal information."

"The solution is stable and I think it does a fantastic job."

"The most valuable feature is spam detection and phishing site prevention, which Microsoft couldn't catch, yet Check Point does."

"Check Point is a good cloud-based solution with respect to email security, and Check Point is a very powerful tool with respect to other OEMs."

"The most valuable feature is the sandboxing feature. It provides a sandboxing environment where you can open links and see where they lead. You can see what is presented in the link after opening it."

"The quarantine and release functionality for malware and junk mail is much more simplified than with previous products, and it has reduced effort in tickets and manpower not needing to do this for people who would have to normally put in a ticket."

"Encryption of emails enhances safe communication that ransomware attacks cannot compromise."

"The initial setup is easy."

More Check Point Email Security (formerly Harmony Email & Collaboration) pros

"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."

"It offers an easy initial setup."

"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."

"The setup was easy."

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

"The solution is scalable."

"Due to our specialized use case, that HIPAA dictionary really comes in handy."

"The most valuable feature is the DMARC Analyzer."

More Mimecast Advanced Email Security pros

Cons

"Cloudflare DDoS has poor technical support."

"For the topic of improvement, providing some training material is one of my suggestions."

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

"The onboarding process can be improved a little bit."

"The response time for support must be reduced."

"Operating and tuning the product is difficult."

"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."

"They don't have a person to provide support for customers using the solution under their free plan."

More Cloudflare One cons

"Sometimes they do not provide immediate assistance, and it can take time for them to respond."

"The sanitization on the file needs improvement."

"Check Point must develop one mobile app for iPhone users, Android phone users, and Windows phone users or at least for the administrator to see that dashboard on that particular app."

"In terms of DLP, there is limited functionality on outgoing DLP specifically."

"After updates, the internet connection fails, and I have to restart my desktop to resume initial functionalities."

"Expanding third-party integration would be beneficial. When I integrate with Microsoft 365, support for other platforms like Slack or Dropbox is limited."

"The implementation could definitely be better. We had great support from Check Point, but there were some "got-you" moments where we got surprises as we were setting it up."

"We still get some false positives. There are times when legitimate stuff gets flagged and it could be that somebody is expecting a very important email but they don't end up getting it. On the flip side, when we alert Check Point about stuff like this, it is corrected, so they are improving. That's a plus."

More Check Point Email Security (formerly Harmony Email & Collaboration) cons

"The price of the solution is expensive. It can improve by reducing the price."

"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."

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

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

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

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

"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."

"The attachment scanning feature doesn't work properly."

More Mimecast Advanced Email Security cons

Pricing and Cost Advice

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

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

"The solution is not that expensive."

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

"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."

"The price is very good, based on what they deliver."

"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."

"Do a full feature evaluation (interactive) with a support person. That is what I did."

"The product is expensive compared to some competitors, especially for the SME segment."

"This is a very good product if you are on the cloud, but the price is a little more expensive."

"It is a bit expensive."

"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."
