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.

Clawback feature performs well but analytics and integration capabilities need improvement
The integration capability with other threat intelligence platforms is not optimal, as I have experienced difficulty in sending logs to our SIEM. Cisco Secure Email Threat Defense's flexibility could be enhanced while it mostly integrates with cloud solutions, but not on-premise. The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious. Regarding room for improvement, the significant number of false positives should be addressed. The solution does not adapt to behavioral analytics and does not make changes when it sees a pattern.

Quotes from Members

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

Pros

"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare DDoS mitigates DDoS attacks."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"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."
"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 tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"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."
"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."
"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 significant enhancement we've gained is in terms of security through the upgrade we received."
"The filtering is definitely better at catching both spam and malicious messages, and there's a lot of extremely granular ability for setting up rules. You can do it the way you want to. The Microsoft solution tends to be pretty limited in how it allows some of that to be done."
"It's flexible. There are a lot of rules and policies that can be easily applied for certain employees or certain mailboxes."
"There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails."
"We like the in-built features, like the email filtering based on the IP and domain. Cisco has its own blacklisted domains and IPs, which is very good. This filters around 70 percent of emails from spam, and we are seeing fewer false positives with this."
"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."
"It has an intuitive, clear graphical interface where you can deploy your policies and understand the overall flow. There are a lot of things that you cannot handle on the graphic interface, like message filters. For this, you need to go to a lower level where you have more power, like command line interface. So, this solution has the best of both worlds. There are not a lot of bells and whistles. It is more practical with access to most features that you can configure."
"If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"The features and functionalities are much better than Microsoft's in-built Defender plan."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."
"Cisco Secure Email Threat Defense's best features include user management of graymail, enhancing security awareness by allowing users to manage cold calls, sales-based items, and ensuring email compliance."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
 

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"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."
"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."
"For the topic of improvement, providing some training material is one of my suggestions."
"We have occasionally had hardware problems because we are using an appliance-based solution, but that might change."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"They could improve the filters. In my time at the company, there were several times we had to contact support to update the filters."
"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."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"They can do it better with web links, with the URLs. They have a technology called Outbreak but it doesn't work as well as we would like."
"The hardware is not up to the mark. Two to three times a year we have complete downtime."
"The interface is dated. It has looked pretty much the same for 15 years or so."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools."
"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
"The solution is a bit expensive."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
 

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 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 solution's pricing lacks transparency."
"Cloudflare Zero Trust Platform's pricing is good."
"The licensing was all transferred."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"It is an expensive product. I rate its pricing an eight or nine."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"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."
"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 is expensive, but we get what we pay for."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"It is expensive compared to other vendors."
"The feedback from vendors and customer is that it is expensive."
"The solution’s pricing is manageable."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
