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.

Decreased our security alerts without impacting employees' work
I can't say that there is one specific feature that is most valuable. It's the overall platform that is well-suited to our needs. It's something that is different from a lot of other products or platforms in the marketplace. It provides a single console for security policy and management. That is somewhat important because we used to have other products where you would have to log in to individual appliances, devices, or clusters. Having one spot to log in to or one area to go to for doing different tasks and viewing data sources, just makes it easier from a user perspective. Also, the fact that it's invisible to our end-users and doesn't affect their work is very important. Most companies don't want to have added friction or impact on their users. In addition, the combination of user-friendliness for admins, and security for the organization, works well. As a cloud-hosted solution, it provides ease of use.

Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare is simple to use."
"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."
"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."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"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."
"Menlo Security RBI has a very good record on stability."
"In addition, the combination of user-friendliness for admins, and security for the organization, works well."
"I can't say that there is one specific feature that is most valuable. It's the overall platform that is well-suited to our needs. It's something that is different from a lot of other products or platforms in the marketplace."
"Menlo Security RBI's best feature is its threat isolation engine."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"The stability of Microsoft Defender for Office 365 is fantastic."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"The coolest feature of Microsoft Defender for Office 365 is its ability to look for phishing emails."
"The product's scalability is good."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
 

Cons

"The onboarding process can be improved a little bit."
"The initial onboarding was causing us some confusion."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Operating and tuning the product is difficult."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The response time for support must be reduced."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Menlo Security RBI could be more cloud-friendly, and its mobility could be improved."
"There are several features, such as supporting web technologies, that the company is working on implementing in the platform. There are a lot of backend web technologies in use on various websites, for example, two-way audio/video and WebGL, for which support may not be fully implemented in the product."
"Menlo Security RBI can be very costly."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"From a development point of view, if I wanted to do development on my actual machine where Defender is, the organization can set certain policies or Defender makes that prohibitive."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"We still see many false positives from time to time with Microsoft Defender for Office 365, so it would be good if we can reduce those false positives and provide better workflows for our end users, as sometimes they may not know what to do when they encounter a false positive."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"The phishing and spam filters could use some improvement."
"The UI needs to be more user-friendly."

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