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

"Enables me to work from two locations."
"Cloudflare Access is a stable solution."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"It will take the blow rather than our applications should an attack occur."
"The solution has different options that can be used to differentiate DDoS attacks."
"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."
"Cloudflare is simple to use."
"The return here is more security and fewer interruptions; it's more stability and productivity versus less productivity, and you could say that you're minimizing your costs by $65,000."
"The added value of it is that every migration to a new version is initiated by the Cisco version itself, so that is a bunch of work that you don't have to do on the Cisco ESA system on-premise. As it becomes a safe platform, you don't need to invest anything in your own data center or in your upgrade path."
"For what you get for the product, the support, and the overall stability, it is definitely a good return on investment."
"Cisco Secure Email Cloud Gateway has allowed our users to be able to concentrate on the emails that they do receive."
"The tech engineers are very knowledgeable."
"It's flexible. There are a lot of rules and policies that can be easily applied for certain employees or certain mailboxes."
"Compared with other mail security things, Cisco Secure Email was much better and easy to deploy also."
"The most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering."
"It is stable and reliable."
 

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."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"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."
"The response time for support must be reduced."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Feedback could be enhanced."
"The hardware is not up to the mark. Two to three times a year we have complete downtime."
"We use the CLI for management, but it's not very good. It's based on Java and it's very difficult to use."
"They can do it better with web links, with the URLs. They have a technology called Outbreak but it doesn't work as well as we would like."
"The pricing needs to be reconsidered or enhanced."
"The user interface could be updated."
"Cisco is not good in dealing proactively or even reactively, so we end up relying on partners."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"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

"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 solution is not that expensive."
"The prices are slightly expensive."
"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 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."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"The price is significantly high."
"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"The licensing was all transferred."
"The licensing is a mess and needs sorting out. I am not really concerned about the pricing because I only make recommendations, not buying decisions."
"It's adapted to the market. It's similar to other vendors. We at least don't have many problems regarding that because Cisco is adaptable on that side. When we present the solutions to the customers, we tend to achieve the goals that the customer has in terms of the budget for such implementations."
