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.

Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

Quotes from Members

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

Pros

"It is a stable solution."
"Clover is the best product globally."
"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."
"It will take the blow rather than our applications should an attack occur."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"The blocking feature is very good."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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."
"This solution provides some benefits, like comfortable access to TAC support. You get prompt support when working directly with Cisco."
"The system provides our service desk with the means to troubleshoot email delivery issues with ease."
"Comparing Microsoft Defender and Cisco's Email Secure service, partners have noted that while Microsoft Defender offers email security, the tool's additional layer of protection provides further defense against threats like spam and phishing emails."
"The system enables end users to manage their own whitelists/blacklists."
"It is a user-friendly product."
"Email service is one of the services that we offer at Galaxy, and Cisco ESA has improved our business so much that our customers want to maintain their business with us for email security, with over 500 domains on our email platform and improved profitability in everything."
"ATP has been the most valuable in improving our email security posture."
"For what you get for the product, the support, and the overall stability, it is definitely a good return on investment."
"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
"We use a few features for web proxy, and another feature is the email content filter and malware for our internal policy in the email content."
"Go for it! I think it's an excellent product with great technical support."
 

Cons

"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"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."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"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."
"Our subscription plan for the solution has a limitation of bot signatures."
"Scalability has certain shortcomings and needs to be improved because there are service providers who provide better scalability.v"
"My opinion on the licensing of this solution is that it is a mess that needs sorting out. I am not particularly bothered by pricing as I administer it and make recommendations for people to buy or not to buy."
"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"Cisco is already providing a very good environment with the IronPort solution, but there could be some more integration with other products. For instance, an integration with the EDR solution could be there to raise an alert."
"The tool's pricing can be improved."
"The solution does not have a strong outbound service. It should also integrate DLP."
"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 configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."
"I am not satisfied with Clearswift because of the lack of customer support."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."
"It is a super big router that costs a few hundred thousand dollars."
"Cisco Secure Email is more expensive than other products. I rate it a five out of ten. There are no additional costs. You only need to pay the subscription amounts."
"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
"There are additional fees for adding features."
"You're going to get what you pay for. If you're not willing to pay the price of Cisco, you're not going to get a product that's as good as Cisco. I don't think Cisco is overpriced, because for the last two years I've been comparing it to Microsoft and Cisco has been cheaper and given us more features."
"In my previous organization, avoiding four instances of CryptoLocker within an estimated six month period is approximately $600,000 in lost time and effort. Our five year cost was about a million dollars, and the four outages that we had equated to 65 percent of that five year cost."
"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."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
