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.

Straightforward to set up, reliable, and offers good functionality
We primarily use the solution for email security and general email management.  It's improved our productivity.  The solution works well overall. The functionality is very good.  The setup process is easy.  It is stable and reliable. It's scalable.  I don't have any specific areas that need…

Quotes from Members

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

Pros

"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 Zero Trust Platform removes the risk of exposing the applications to the public."
"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"I'm very satisfied with the environment and the dashboard."
"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."
"The blocking feature is very good."
"The logs are easily readable and help diagnose problems, although they can be difficult to find initially. The solution addresses our email security, but for the rest of our security, we would use multiple vendors. It covers everything through email, like antivirus, IDS, and IPS."
"The most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering."
"From a functionality perspective, the platform is great."
"This solution provides some benefits, like comfortable access to TAC support. You get prompt support when working directly with Cisco."
"The Cisco Email Security Appliance has enabled us to reduce spam by at least 30% compared to our previous solution."
"The Cisco Secure Email Gateway, in my opinion, is a really good device."
"IronPort really helped with the mail filtering and load balancing between the Exchange servers they had."
"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."
"It is stable and reliable."
 

Cons

"The initial onboarding was causing us some confusion."
"The onboarding process can be improved a little bit."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Operating and tuning the product is difficult."
"For the topic of improvement, providing some training material is one of my suggestions."
"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."
"They don't have a person to provide support for customers using the solution under their free plan."
"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."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"The interface is dated. It has looked pretty much the same for 15 years or so."
"The user interface could be updated."
"Cisco Email Secure's pricing needs to be less. We have vendors who provide cheaper solutions with the same features."
"The management features of the product are not up to date."
"The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear."
"We cannot manage multiple devices from a single UI."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"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 prices are slightly expensive."
"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 solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"The licensing was all transferred."
"It is a relatively expensive option compared to other alternatives."
"Pricing depends on your environment and which model you want to buy."
"Cisco Secure Email is expensive, but we get what we pay for."
"It is an expensive product. I rate its pricing an eight or nine."
"There are additional fees for adding features."
"Compared to Cisco's on-prem service, the cost is the same, but you don't have to pay for the hardware and you don't have to maintain the system, as far as upgrades and hardware failures are concerned. It is cheaper to operate on their cloud service than it is to operate with their on-prem service."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
