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.

Monitoring has improved data loss detection and now spots abnormal internal file transfers quickly
In my understanding, the best feature Darktrace offers is the identification of copying files, which acts as a DLP, and it is a main concern for companies because users sometimes copy data outside without knowing, especially those without a technical background. When I mention the DLP-like feature and file copying detection, the alerts have been very timely, as we get an alert within a couple of minutes, which is excellent. Even if some developers are working after hours and copying files, our SOC team detects this, and most of the time they call us so we can identify the users. The alerts are quite accurate and proactive.

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 blocking feature is very good."
"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."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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."
"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."
"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 tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"I highly recommend the overall solution to other users and rate it as nine out of ten."
"The Enterprise Immune System, Cyber Artificial Intelligence Analyst, and Antigena technology are all very useful aspects of the product."
"It is a stable solution without downtime."
"I find the complete portfolio to be excellent."
"I am impressed with the product's ability to give insights into network traffic."
"I like the Antigena feature in Darktrace, as it offers immediate response and is helpful."
"I have used multiple solutions, but its graphical user interface is quite interesting and quite descriptive. There are a lot of video animations, and we can easily see how the data is transferred between various points. That's something really interesting. It is also quite easy to understand for a new user."
"I have found the automation and AI features to be valuable. If someone were to come in to the office at midnight and log in, Darktrace would flag it."
"The security is pretty good, and that's why we're going to upgrade to an even more advanced package. We used it when we had a power issue, and it works. It has been pretty reliable, and the support has been quite good."
"URL inspection works pretty well."
"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."
"The setup was easy."
"The Large File Send feature comes in handy when you have to send fairly large attachments."
"The solution's performance is good."
"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."
"Mimecast Advanced Email Security proves to be a useful tool, allowing me as security personnel to work in a more peaceful manner."
 

Cons

"Cloudflare DDoS has poor technical support."
"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."
"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."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"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."
"The one downside is the pricing, which is quite high."
"In terms of improvements, fine-tuning is the area where we have to spend some time because it works on unsupervised machine learning."
"The main portal needs improvement as it is difficult to use."
"It would be good if they can include some endpoint protection for remote workers."
"Darktrace needs to simplify most of the positive reports. We have to field all the positive reports, false positives, too."
"Darktrace does not have any capabilities to configure. So I would like to see supervised machines and capabilities in the next version."
"The interface and dashboards could be improved for ease-of-use."
"The user interface and the configuration are a bit complex and should be improved or simplified."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
"As a user, the user interface of the management console could be upgraded, for example."
"The lock in is very, very tight. It is impossible to move out of Mimecast to a different product, like Proofpoint or 365 ATP, and keep the chain of custody for every email that I've archived."
"Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts."
"The product's interface could be improved to be more user-friendly."
"I'd like to have better support from the product in the future."
"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."

"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 solution's pricing lacks transparency."
"This solution is expensive."
