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

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"It will take the blow rather than our applications should an attack occur."
"Cloudflare DDoS mitigates DDoS attacks."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare is by far the most effective solution that I have come across."
"I'm very satisfied with the environment and the dashboard."
"The solution has different options that can be used to differentiate DDoS attacks."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Compared with other mail security things, Cisco Secure Email was much better and easy to deploy also."
"Capital expenditure is a significant consideration, and the impact on major expenditures prompts a careful analysis before onboarding the new product."
"It is doing its work. It is doing what it was actually designed to do. It has ensured we don't have business email compromises, and it has also ensured that our brand Galaxy is unique all year round."
"The system provides our service desk with the means to troubleshoot email delivery issues with ease."
"Anti-Spam and Advanced Malware Protection are the most valuable features... and we also have the option to block Zero-day attacks."
"The most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering."
"There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails."
"The tool has a DLP solution which we can implement. Its database is updated regularly."
"It is stable and reliable."
 

Cons

"They don't have a person to provide support for customers using the solution under their free plan."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Feedback could be enhanced."
"The response time for support must be reduced."
"Our customers no longer use Cloudflare because its service is subpar."
"The initial onboarding was causing us some confusion."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The solution does not have a strong outbound service. It should also integrate DLP."
"The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."
"Many smaller businesses opt for more cost-effective solutions, such as Gmail or Hotmail accounts, instead of investing in Cisco Secure Email, given its higher cost."
"The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"The user interface needs some improvement to become more user-friendly. The graphics could be better. It's designed more for a technical user rather than a business user."
"The hardware is not up to the mark. Two to three times a year we have complete downtime."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"The solution could be less expensive."
 

Pricing and Cost Advice

"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."
"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 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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"It is a super big router that costs a few hundred thousand dollars."
"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."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"There were no other costs in addition to the standard licensing fees."
"It is a relatively expensive option compared to other alternatives."
"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 pricing for the Cisco Email Security Appliance involves recurring costs for licenses based on the contracted time frame, such as one year, three years, or five years. Renewals are required after the license expires."
