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.

Useful for cloud data protection, particularly for email and file-sharing systems
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. The solution should also expand integration from the public cloud to the private cloud and add Cloud DLP and CASB features.

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."
"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 is a stable solution."
"Cloudflare DDoS mitigates DDoS attacks."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"The blocking feature is very good."
"The solution has different options that can be used to differentiate DDoS attacks."
"It will take the blow rather than our applications should an attack occur."
"My experience deploying Microsoft Defender for Office 365 was seamless."
"The email protection is excellent, especially in terms of anti-phishing policies."
"The DLP feature of Microsoft Defender for Office 365 is valuable, and we also use the DLP feature for email real-time detection."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"Does a thorough job of examining email and URLs for malicious content."
"Dependable with ease of integration with other security products."
"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."
"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."
"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."
"The initial setup is pretty straightforward."
"The solution is easy to integrate."
"Trend Micro Cloud App is easy to use and easy to install."
 

Cons

"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"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."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"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."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."
"I assess the stability and reliability of the solution as seven out of ten."
"There's room for improvement regarding the time frame for retrieving emails."
"To improve Microsoft Defender for Office 365, it would be nice to have more accessibility for users to see on their end what they are doing that could cause a threat."
"If you look at other products, such as Wiz or Palo Alto's cloud, because they also have similar components in terms of how they protect cloud infrastructure or enable cloud security, Microsoft Defender for Office 365 is not up to that extent."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"There is room for improvement in terms of reporting."
"The granulation of the policy setup needs to be better. Right now, it is too basic."
"The pricing of this solution is quite high, about double what other similar solutions cost."
"Documentation could be improved; product cost is quite high."
"They should provide separate corporate-level licenses for two to three instances."
"There is room for improvement in the DLP component of Trend Micro Cloud App Security."
"The price of the solution could improve by being lower."
"It would be great if Trend Mail Cloud App Security would be joined with a web security solution, making it a multiple-network solution."
"The solution's technical support services could be better."
 

Pricing and Cost Advice

"The prices are slightly expensive."
"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 is not that expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"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."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution's pricing lacks transparency."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing has become expensive."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The product is very expensive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"The license is expensive because the cost is based on the number of users."

"The cost of the license is on the high side. It's a yearly subscription."
"The pricing of the solution could be better."
