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 tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare Access is part of the Zero Trust philosophy."
"Enables me to work from two locations."
"The blocking feature is very good."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"It is a stable solution."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"The main benefit is that hackers can't steal information."
"Its characteristics are adapted to the most modern threats."
"It is the collaboration between users inside the company. It is a big advantage with Check Point to be able to work together on the same document."
"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."
"Being able to keep the phishing campaigns out of my company has been ROI for me."
"The solution helps to block spam emails."
"As Check Point is a leading technology in the industry, it provides maximum protection against email phishing attacks and provides the identity of users and visibility over shadow IT applications."
"We can say that with Check Point Cloud Guard SaaS, we have improved our security to the next level."
"If you want the ease of use, then Mimecast, or at least a cloud solution, is the way to go."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"We're now certain business-critical mail is perfectly protected in multiple ways."
"It offers an easy initial setup."
"Mimecast Advanced Email Security proves to be a useful tool, allowing me as security personnel to work in a more peaceful manner."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail."
"The security on offer is very good."
 

Cons

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The initial onboarding was causing us some confusion."
"Feedback could be enhanced."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"For the topic of improvement, providing some training material is one of my suggestions."
"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."
"They don't have a person to provide support for customers using the solution under their free plan."
"Support could be improved, as it is only available in English."
"Check Point needs to address the pricing segment for SMEs."
"After updates, the internet connection fails, and I have to restart my desktop to resume initial functionalities."
"Check Point's technical support is very much of a low level, especially with respect to other vendors and OEMs."
"There is too much functionality, which makes it difficult to use. More guidance for users would be helpful."
"A phishing simulator would be helpful as a user training module."
"The portal site is a bit slow at times. Plus, all new functions seem to be 'add-ons' instead of just being part of the platform."
"Since the portal to the management and administration entry sometimes has performance problems and takes a long time to respond to what has arrived, the handling of the tool is difficult."
"The feature that should be included is to remove the block on the encrypted files."
"They should improve the cookies management feature."
"The price could be better, it should be reduced."
"External security features need improvement."
"The interface and the documentation could be improved."
"While it's quick and easy, the initial setup could be more user-friendly."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"The installation is not so straightforward."

"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."
