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.

Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.

Quotes from Members

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

Pros

"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."
"I'm very satisfied with the environment and the dashboard."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Cloudflare Access is part of the Zero Trust philosophy."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"The blocking feature is very good."
"It is a stable solution."
"It is a user-friendly product."
"The tech engineers are very knowledgeable."
"The system enables end users to manage their own whitelists/blacklists."
"For what you get for the product, the support, and the overall stability, it is definitely a good return on investment."
"It has the ability to tell us, after an email has been delivered, where else it went, once it got inside. Maybe it's something we wanted it to stop and it didn't stop it, but it notified us later that it was something that it should have stopped. It can give us a trajectory of all the other places that it went internally and it can tell us what files were transferred as well."
"ATP has been the most valuable in improving our email security posture."
"Users were able to do a check by themselves on quarantined emails. They could check if a valid email had been stopped, if it matched up with the SPF certification."
"The technical support from Cisco is perfect."
"The simplicity and the easy deployment ensure that anybody who has worked on Exchange can easily work on this."
"The product protects against malware."
"The email policy configuration options in Microsoft EOP are satisfactory."
"The security features provided by Microsoft are robust."
"With Microsoft Exchange Online Protection, if malware is attached to a mailer, it's very easy to go into the incident alert and find out what's happening with that identity and the mail."
"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."
"It is useful for local users and our company because we use Microsoft 365."
"It has a really nice web-based administration console."
 

Cons

"Our subscription plan for the solution has a limitation of bot signatures."
"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."
"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."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The response time for support must be reduced."
"Feedback could be enhanced."
"I would like to see features like AI since it is currently an area that the product lacks."
"There could be additional DLP functionality for it."
"I use the search all the time. Sometimes, it is hard to search for things and things are hard to find."
"The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console."
"Cisco Email Secure's pricing needs to be less. We have vendors who provide cheaper solutions with the same features."
"The initial setup was complex because I have two sites with physical clusters."
"Added cost and delay to the network traffic, but performance did remain stable."
"The user interface is a bit complex."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"The reporting needs a little bit of improvement."
"Our Exchange system is very locked down and secure, yet we still got hacked."
"It kind of has a heavy footprint in terms of an implementation footprint."
"The solution can be complex at times. It would be nice to have the on-server version. It needs to improve the stability as well."
"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
"Microsoft 365 Defender and EOP policies are stable with the proper license. However, with the basic policy, it's hard to say it's stable due to configuration limitations."
"The security features could be better and more secure in the next release."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution's pricing lacks transparency."
"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."
"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"As per market availability, this solution is more expensive than other vendors."
"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
"There were no other costs in addition to the standard licensing fees."
"The price is significantly high."
"It is an expensive product. I rate its pricing an eight or nine."
"At times, we feel the pricing is a bit too high, but then, there is also room for discounts. We enjoy a lot of discounts, and that is why we are still with them. There are no costs in addition to the standard licensing fees."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"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 is bundled with Microsoft 365."
"The product is expensive."
"Regarding the price, it's comparable to other service providers. We've also looked at Check Point's offerings, and the pricing doesn't seem to be an issue."
"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."
"The tool's pricing is excellent."
"It's a high price."
"It is a low-price solution."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
