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

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"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."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare Access is a stable solution."
"Cloudflare is simple to use."
"It is a stable solution."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"I can customize the configuration and policies."
"The security features are valuable."
"It provided a platform to sell a service to customers."
"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 most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering."
"The tool comes with AI features. It is good for clients who already use Cisco products due to integration."
"There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails."
"We chose Cisco Iron Port as it delivers strong email security protection and our company needed it to protect the company's email systems from spam, email viruses, .exe files, unwanted email from unwanted sender etc."
"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
"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

"Our customers no longer use Cloudflare because its service is subpar."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Operating and tuning the product is difficult."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Our customers no longer use Cloudflare because its service is subpar."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"They don't have a person to provide support for customers using the solution under their free plan."
"The product's GUI for the dashboard needs improvement."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."
"Cisco Secure Email can be improved from the administrator's point of view. Usually, you have to work with different areas, and they can try to make it easy for the administrator to use different functions."
"I use the search all the time. Sometimes, it is hard to search for things and things are hard to find."
"We have been struggling in the last month with Cisco encryption and with the S/MIME encryption."
"Cisco Email Secure's pricing needs to be less. We have vendors who provide cheaper solutions with the same features."
"The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear."
"FTP server and TRUST Manager functionality."
"FTP server and TRUST Manager functionality."
"I am not satisfied with Clearswift because of the lack of customer support."
"Malware needs improvement."
 

Pricing and Cost Advice

"The prices are slightly expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that 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."
"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's pricing lacks transparency."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"It is a super big router that costs a few hundred thousand dollars."
"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 license was not per user, the license model was per feature. You could choose anti-virus, anti-spam, etc. It was feature-based and charged yearly."
"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
"The pricing is good."
"The price is significantly high."
