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.

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

"Cloudflare, in my opinion, was easy to implement."
"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 is by far the most effective solution that I have come across."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Enables me to work from two locations."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"It will take the blow rather than our applications should an attack occur."
"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 insights provided with Microsoft Defender for Office 365 are helpful because it comes with the E5 license, and by default, we can use a lot of capabilities."
"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."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"The insights provided with Microsoft Defender for Office 365 are helpful because it comes with the E5 license, and by default, we can use a lot of capabilities."
"There are several features that I consider valuable."
"The solution is easy to integrate."
"The most valuable feature of Trend Micro Cloud App Security is its stability across all platforms."
"The initial setup is pretty straightforward."
"It has more intelligence features than other vendors."
"Trend Micro Cloud App is easy to use and easy to install."
"I find Trend Micro Cloud App Security useful for scanning our email boxes. We can scan them one by one, which is a good feature. It's not just gateway-level protection - we integrate the email system with it. They have special protection and parameters for phishing emails."
"Our business emails are very important and Trend Micro Cloud App Security has provided a high level of protection. Additionally, there are updating the solution frequently."
"Trend Micro has DLP features in it, which separates it from other solutions."
 

Cons

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The response time for support must be reduced."
"Cloudflare DDoS has poor technical support."
"The onboarding process can be improved a little bit."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"Operating and tuning the product is difficult."
"Our subscription plan for the solution has a limitation of bot signatures."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"The price of the solution could improve by being lower."
"They should provide separate corporate-level licenses for two to three instances."
"The granulation of the policy setup needs to be better. Right now, it is too basic."
"For improvements, I think it would be great if Trend Micro Cloud App Security could enhance their product to be a single SASE solution. It should be similar to competitors like Palo Alto."
"There is room for improvement in the DLP component of Trend Micro Cloud App Security."
"Documentation could be improved; product cost is quite high."
"In the next release, I would like to see the cost go down."
"The solution's technical support services could be better."
 

Pricing and Cost Advice

"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
