Threat intelligence with fast attack detection enables comprehensive email protection
In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam. This could result in users not opening genuine emails. We have highlighted this to Cisco because sometimes phishing or marketing campaigns, which are genuine, are incorrectly flagged as spam. The solution should better analyze the actual content rather than only focusing on the email header or origin.

Network Architect at IP Dimension
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.

Quotes from Members

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

Pros

"We rely heavily on antivirus protection, email content filtering, and authentication mechanisms to ensure compliance with email security. Regarding phishing attempts, while phishing protection features are crucial, we also emphasize user education as a critical defence. The intelligence services Cisco provides, such as the Cisco Intelligence Center, play a significant role in analyzing and validating threats, including phishing attempts, in our email security practices."
"Initially, the most valuable feature for us was the SenderBase Reputation, because that reduced the number of emails that were even considered by the system by a huge number..."
"The solution works well."
"Cisco Secure Email is part of Cisco's extensive efforts and investments in technology, especially in the realm of cyber security. The product is one among many security solutions offered by Cisco."
"What I find the most valuable about Cisco Secure Email is that the logs are not that difficult to see even if you're not used to them. The logs are reasonably readable and diagnosing the problem is not too hard with them."
"ATP has been the most valuable in improving our email security posture."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"The system provides our service desk with the means to troubleshoot email delivery issues with ease."
"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."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare DDoS mitigates DDoS attacks."
"I'm very satisfied with the environment and the dashboard."
"The solution has different options that can be used to differentiate DDoS attacks."
"Cloudflare is simple to use."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Enables me to work from two locations."
 

Cons

"I would like them to add some clustering or high availability features."
"We would like to see more options for the customization of content filters."
"I am not satisfied with the solution's reporting and logging."
"The interface is dated. It has looked pretty much the same for 15 years or so. It would be helpful to be able to do everything from one spot. The centralized quarantine and reporting are completely separate from policy administration."
"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."
"The reporting functionality needs to be improved."
"The discontinuation of physical hardware solutions is a significant area for improvement in Cisco Email Security Appliance. This decision has posed challenges as virtual appliances are now the only option, which may not be suitable for all industries. The uncertainty regarding the future of the hardware aspect of the solution is a notable concern."
"If you are not a technical guy, it is hard to maneuver, but as soon as you work on it, it gets better and better. If there was a better way to know how to do things or how to find things, it would be good."
"Cloudflare DDoS has poor technical support."
"The response time for support must be reduced."
"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."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The initial onboarding was causing us some confusion."
"Operating and tuning the product is difficult."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
 

Pricing and Cost Advice

"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."
"As per market availability, this solution is more expensive than other vendors."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"The licensing was all transferred."
"The solution is expensive."
"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
"Pricing depends on your environment and which model you want to buy."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"Cloudflare Zero Trust Platform's pricing is good."
"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."
"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."
"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."
