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.

Email security has protected financial data and provides clear tracking for every branch message
The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Cloudflare Access is a stable solution."
"Cloudflare is by far the most effective solution that I have come across."
"It is a stable solution."
"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."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"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."
"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."
"Overall, it is a very good product, and I'm very happy with it."
"The tool's most valuable feature in preventing security breaches revolves around the area of malware protection that the product provides."
"It saves a lot of time wasting, for example, phishing attacks distract a user's attention and forged emails waste a lot of time, and this solution helps protect user data."
"It integrates with Active Directory and we can limit specific users to using specific applications."
"The most valuable feature is the different content filters we are using, such as DKIM."
"The product's initial setup phase was easy."
"This product is the complete solution and the real deal."
"My favorite feature of Cisco Secure Email is the threat intelligence capabilities, particularly its integration with Cisco Talos."
"It is stable and reliable."
 

Cons

"The response time for support must be reduced."
"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."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Operating and tuning the product is difficult."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"For the topic of improvement, providing some training material is one of my suggestions."
"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."
"Our subscription plan for the solution has a limitation of bot signatures."
"Licensing is quite complicated for a number of customers, including ourselves."
"I would like more functionality and how to use it for Level 2 type staff. The biggest issue is it needs to be easier to use and navigate."
"They can do it better with web links, with the URLs."
"I would like them to add some clustering or high availability features."
"We use the CLI for management, but it's not very good. It's based on Java and it's very difficult to use."
"We have occasionally had hardware problems because we are using an appliance-based solution, but that might change. We may consider going to virtual systems."
"The interface is dated. It has looked pretty much the same for 15 years or so. It would be helpful to be able to do everything from one spot. The centralized quarantine and reporting are completely separate from policy administration."
"The area of license renewal should be improved. We normally renew our license every year."
"The solution could be less expensive."
 

Pricing and Cost Advice

"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 solution's pricing lacks transparency."
"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution is not that expensive."
"The prices are slightly expensive."
"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."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"There are additional fees for adding features."
"The pricing is good."
"It is a super big router that costs a few hundred thousand dollars."
"It is an expensive product. I rate its pricing an eight or nine."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"The solution is expensive."
"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
