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

"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."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"It will take the blow rather than our applications should an attack occur."
"It is a stable solution."
"The solution has different options that can be used to differentiate DDoS attacks."
"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."
"Cloudflare DDoS mitigates DDoS attacks."
"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."
"The solution is easier to manage than FortiMail. You can implement policies easily."
"It helps reduce spam and phishing attacks."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"The basic features are okay and I'm satisfied with the Defender."

"There are several features that I consider valuable."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"The initial setup was easy."
 

Cons

"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."
"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."
"For the topic of improvement, providing some training material is one of my suggestions."
"Our customers no longer use Cloudflare because its service is subpar."
"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."
"The initial onboarding was causing us some confusion."
"The response time for support must be reduced."
"The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very quickly."

"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"It is not up to the mark in comparison with Wiz or Palo Alto."
"There is room for improvement in terms of reporting."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"There's room for improvement regarding the time frame for retrieving emails."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
 

Pricing and Cost Advice

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"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."
"The solution's pricing lacks transparency."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"Email Security Gateway's pricing is good."
"It's a user-base subscription."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"I know that the product is incredibly expensive."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"The product is expensive."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"The pricing has become expensive."
