Network Architect at IP Dimension
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 is by far the most effective solution that I have come across."
"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."
"Cloudflare Access is a stable solution."
"Enables me to work from two locations."
"Cloudflare is simple to use."
"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."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"The initial setup was easy."
"Since we have started using the solution, there have been fewer compromises."
"It has significantly decreased my time to detection and response."
"The technical support is good and quick to resolve issues."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"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."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"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."
"The most valuable feature of Trend Micro Cloud App Security is its stability across all platforms."
"Trend Micro Cloud App is easy to use and easy to install."
"The solution is easy to integrate."
"Trend Micro has DLP features in it, which separates it from other solutions."
"Trend Micro has DLP features in it, which separates it from other solutions."
"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."
"This is a very dependable solution and we are able to have a lot of Trend Micro security products integrated between each other."
 

Cons

"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."
"Our customers no longer use Cloudflare because its service is subpar."
"The initial onboarding was causing us some confusion."
"Our customers no longer use Cloudflare because its service is subpar."
"Our subscription plan for the solution has a limitation of bot signatures."
"Cloudflare DDoS has poor technical support."
"Feedback could be enhanced."
"For the topic of improvement, providing some training material is one of my suggestions."
"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."
"In the areas of improvement for Microsoft Defender for Office 365, the console is the biggest challenge for me."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"Several simulation options are available within 365, and the phishing simulation could be better."
"There needs to be an improvement in having the product work across multiple operating systems and have better support for non-Microsoft file types."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"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."
"The cost of the license is on the high side."
"There is room for improvement in the DLP component of Trend Micro Cloud App Security."
"Documentation could be improved; product cost is quite high."
"It would be great if Trend Mail Cloud App Security would be joined with a web security solution, making it a multiple-network solution."
"They should provide separate corporate-level licenses for two to three instances."
"In the next release, I would like to see the cost go down."
"The solution's technical support services could be better."
"The pricing of this solution is quite high, about double what other similar solutions cost."
 

Pricing and Cost Advice
