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 tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare is simple to use."
"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."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Enables me to work from two locations."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"It will take the blow rather than our applications should an attack occur."
"Microsoft Defender for Office 365 saves me time; it does save a lot of time, especially with the automation."
"Does a thorough job of examining email and URLs for malicious content."
"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 feature I like the most about Microsoft Defender for Office 365 is that it typically runs in the background—you do not know it is there until you need to access it."
"The basic features are okay and I'm satisfied with the Defender."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"The technical support is good and quick to resolve issues."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"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."
"It has more intelligence features than other vendors."
"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."
"The most valuable feature of Trend Micro Cloud App Security is its stability across all platforms."
"This is a very dependable solution and we are able to have a lot of Trend Micro security products integrated between each other."
"Dependable with ease of integration with other security products."
"Trend Micro Cloud App is easy to use and easy to install."
 

Cons

"Operating and tuning the product is difficult."
"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."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Our customers no longer use Cloudflare because its service is subpar."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The initial onboarding was causing us some confusion."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"For the topic of improvement, providing some training material is one of my suggestions."
"The GUI is sometimes slow to fetch the device report and could be improved."
"In the areas of improvement for Microsoft Defender for Office 365, the console is the biggest challenge for me."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"This is quite an expensive solution and understanding the pricing model and features is quite complicated and it can, in fact, be a nightmare when dealing with Microsoft."
"I assess the stability and reliability of the solution as seven out of ten."
"The granulation of the policy setup needs to be better. Right now, it is too basic."
"The solution's technical support services could be better."
"The price of the solution could improve by being lower."
"The pricing of this solution is quite high, about double what other similar solutions cost."
"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."
"The cost of the license is on the high side."
"In the next release, I would like to see the cost go down."

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Cloudflare Zero Trust Platform's pricing is good."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution is not that expensive."
