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.

Technical Associate Network Security at Valuepoint Systems

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.

Glenn-Camilien

Senior Cybersecurity Engineer at a financial services firm with 11-50 employees

Provides robust email security features but requires improved modernization and complexity management

Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

Quotes from Members

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

Pros

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"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."

"Cloudflare, in my opinion, was easy to implement."

"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 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."

"Cloudflare DDoS mitigates DDoS attacks."

"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."

More Cloudflare One pros

"It integrates with Active Directory and we can limit specific users to using specific applications."

"It's definitely worth looking at Cisco's cloud email security offering; it's surprisingly simple to get going with, it really is easier to use than the on-prem because of everything they have built into it, and it is surprisingly cost-effective."

"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."

"Capital expenditure is a significant consideration, and the impact on major expenditures prompts a careful analysis before onboarding the new product."

"Compared with other mail security things, Cisco Secure Email was much better and easy to deploy also."

"The product blocks spam emails."

"Introducing Cisco Secure Email Gateway systems was a set change for us and reduced the number of unwanted emails by a huge factor, a benefit that has continued from when we first got the devices until today."

"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."

More Cisco Secure Email pros

"The features and functionalities are much better than Microsoft's in-built Defender plan, and this product has helped us to protect our organization from any malware attack in the past."

"It has an efficient email filtering feature."

"The solution is stable."

"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."

"Regarding stability, Cisco Secure Email Threat Defense is very stable."

"This solution is easy to use."

"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."

"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."

More Cisco Secure Email Threat Defense pros

Cons

"Cloudflare DDoS has poor technical support."

"Our customers no longer use Cloudflare because its service is subpar."

"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."

"Operating and tuning the product is difficult."

"Feedback could be enhanced."

"They don't have a person to provide support for customers using the solution under their free plan."

More Cloudflare One cons

"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."

"Better dashboards and more interactive overviews would be nice, but the current functionality is sufficient."

"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."

"They can do it better with web links, with the URLs."

"The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."

"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."

"Typically, in a phishing email, they try to use a name everybody's going to recognize, like the CEO's name or the CFO's name... With this appliance, the way it's designed at the moment, for us to really stop that with any level of confidence, we have to build a dictionary of all the names of the people we want it to check, and all the ways they could be spelled. My name would be in there as Phillip Collins, Phillip D. Collins, Phillip Dean Collins, Phil Collins, Phil D. Collins. There could be eight or 10 variations of my name that we'd have to put in the dictionary. There's no artificial intelligence to say "Phil Collins" could be all these other things, and to stop phishing from coming through in that way."

"The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."

More Cisco Secure Email cons

"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."

"The search area has room for improvement."

"This solution could be improved by integration with Sandbox."

"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."

"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."

"The solution is a bit expensive. It could be cheaper."

"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."

"The physical appliance has been discontinued, although the platform still exists."

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."

"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"The solution is expensive."

"There are additional fees for adding features."

"The licensing is a mess and needs sorting out. I am not really concerned about the pricing because I only make recommendations, not buying decisions."

"It's adapted to the market. It's similar to other vendors. We at least don't have many problems regarding that because Cisco is adaptable on that side. When we present the solutions to the customers, we tend to achieve the goals that the customer has in terms of the budget for such implementations."

"The price is significantly high."

"I rate the pricing a ten out of ten on a scale where one means it is less cost-effective, and ten means it is the most cost-effective solution."

"There were no other costs in addition to the standard licensing fees."

"It is not that costly. We pay for the solution through a contractor and pay an annual fee."

More Cisco Secure Email pricing and cost advice

"The feedback from vendors and customer is that it is expensive."

"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."

"The solution’s pricing is manageable."

"It is expensive compared to other vendors."
