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

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare Access is part of the Zero Trust philosophy."
"The solution has different options that can be used to differentiate DDoS attacks."
"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."
"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."
"Cloudflare is simple to use."
"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."
"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"You can have a one-person IT team and with Darktrace, you can get notification of potential threats that are incoming or are already happening on the network."
"t was pretty as far as the granularity of what you were getting out of it."
"Darktrace is extremely stable."
"We allow customers to access our Wi-Fi as guests, and some of them were going to restricted sites. Darktrace showed us what they were doing so we could block them."
"The most valuable features of Darktrace are the tracing of unusual external emails and monitoring the local network."
"The most valuable feature is the endpoint protection."
"What I like about Darktrace, is that you can quickly identify threats."
"The technical support from Darktrace is very good, including support from their resellers."
"The solution's performance is good."
"The initial setup is easy."
"The reviewer gave Mimecast Email Security a rating of 10 out of 10."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
"Mimecast has been in the market for a long time; it's a good tool if you want to simplify your operations and a good tool for removing on-prem appliances that otherwise you would need to do with the protection that Mimecast provides."
"Email security is the most valuable feature of the solution."
"The positive impact of Mimecast Advanced Email Security on our organization is evident in how it has drastically reduced spam emails and improved our data security."
"The setup was easy."
 

Cons

"Feedback could be enhanced."
"Our customers no longer use Cloudflare because its service is subpar."
"The onboarding process can be improved a little bit."
"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."
"The initial onboarding was causing us some confusion."
"Our subscription plan for the solution has a limitation of bot signatures."
"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."
"It's quite expensive to have."
"It would be helpful if they could recognize incidents and simplify the customer's challenge to identify what is happening."
"Darktrace needs to automate the reports of false positives, botnets and everything."
"Its threat analyzer could be better. It should also have agents."
"It can have more integration with orchestration or event management solutions. They can provide more knowledge or research information for analysts for investigating cases and detecting anomalies in networks."
"The initial setup is more complex and time-consuming than some solutions."
"There is a high ratio of false positive information."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution. Even when I posted questions on the community chats, it took a lot of time for me to get answers. That's something that can be improved. Darktrace can focus on creating a more interactive community. If there are more people from Darktrace to focus on community chats, it would be better."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The price could be better, it should be reduced."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
"Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts."
"I'd like to have better support from the product in the future."
"The solution is very expensive."
"We discussed the phishing aspect, the DNS system, and the key rotation."
