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

Quotes from Members

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

Pros

"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"It is a stable solution."
"Clover is the best product globally."
"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."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"The blocking feature is very good."
"Cloudflare is simple to use."
"It sends us reports, where we can see if there have been attacks, e.g. DDoS. If so, we can switch to a clean IP."
"The tool comes with AI features. It is good for clients who already use Cisco products due to integration."
"The tool's most valuable feature in preventing security breaches revolves around the area of malware protection that the product provides."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"The strong point of the solution is that we hardly get any spam emails because of Cisco Secure Email."
"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 security features are valuable."
"Cisco Secure Email has strong inbound services."
"It is stable and reliable."
 

Cons

"Operating and tuning the product is difficult."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Our customers no longer use Cloudflare because its service is subpar."
"The response time for support must be reduced."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Cloudflare DDoS has poor technical support."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The initial onboarding was causing us some confusion."
"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."
"The management features of the product are not up to date."
"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."
"I would like them to add some clustering or high availability features."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"The user interface is a bit complex."
"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."
"In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam."
"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."
"The solution is not that expensive."
"The solution's pricing lacks transparency."
"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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."
"Pricing depends on your environment and which model you want to buy."
"Cisco Secure Email is expensive, but we get what we pay for."
"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 a super big router that costs a few hundred thousand dollars."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"Cisco Secure Email and the support are priced well. It's not cheap, but there are other solutions that offer less and cost so much. For example, Microsoft is more expensive than Cisco."
"The product's price falls on the higher side when compared to the other products on the market."
