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

"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."
"Cloudflare Access is a stable solution."
"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 best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"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."
"Enables me to work from two locations."
"Clover is the best product globally."
"There are a lot of filters for scam emails and things like that work out of the box. You can also use the antivirus features. I like its features."
"The malicious URL scanning, as well as the anti-malware features, have been really useful for us in our environment."
"The most valuable feature is the different content filters we are using, such as DKIM."
"Cisco Secure Email Cloud Gateway has allowed our users to be able to concentrate on the emails that they do receive. Previously, our users had to deal with nine million additional emails across the organization, which is nearly 1,000 emails per user to have to deal with a month. That's a massive amount for our staff to deal with and probably several hours of their time. We have a lot of clinical staff, being a hospital. We want to make our staff as productive as possible. By removing a lot of that spam and phishing type emails, this allows them to do their job."
"The logs are easily readable and help diagnose problems, although they can be difficult to find initially. The solution addresses our email security, but for the rest of our security, we would use multiple vendors. It covers everything through email, like antivirus, IDS, and IPS."
"The Cisco Secure Email Gateway, in my opinion, is a really good device."
"This is a great product with wonderful support."
"Because we scan products, and there is a lot of critical data, security is very important in these cases."
"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."
"Microsoft EOP's most valuable feature is a shared mailbox."
"You can use the product to create special accounts."
"It provides security to both on-premises and Azure infrastructures."
"The initial setup is just a standard process."
"Overall, I think it's really a great product."
"It is useful for local users and our company because we use Microsoft 365."
"The most valuable feature of Microsoft Exchange Online Protection is the accidental release of information protection capabilities, and additionally, the solution is easy to use."
 

Cons

"Feedback could be enhanced."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"For the topic of improvement, providing some training material is one of my suggestions."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The response time for support must be reduced."
"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."
"The initial onboarding was causing us some confusion."
"I would like them to add some clustering or high availability features."
"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."
"The product's GUI for the dashboard needs improvement."
"It would be nice to have an easier way to check on the health of the system, how stressed these appliances are. Sure, you can do it, but it would be helpful to have an easier way to do it, maybe even at a glance."
"The solution needs to improve its advanced phishing filters. It is very good at filtering things which have bad reputations. However, when phishing or malicious emails are new or coming from a legitimate source, we don't feel that the solution is working."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"While Cisco offers excellent solutions and innovations, the pricing may not be suitable for everyone. The cost of the software is relatively high. In the current market, there are numerous competitive alternatives that focus on security, enterprise networks, and various other aspects. Cisco, being a comprehensive provider, extends its expertise across data, servers, storage, and security, making them a preferred choice for many enterprises. However, when it comes specifically to security solutions, there are other vendors that specialize solely in this domain, offering competitive options."
"It takes time to harmonize information from the email log events with higher level reporting tools."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"Microsoft Exchange Online Protection is quite a difficult product."
"We would like the solution to have more in-built intelligence in the way that it reviews potential security risks, rather than our team constantly having to update the policies."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
"I am somewhat happy with technical support from Microsoft. Sometimes it takes a while to get through to the right person or team."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
"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."
 

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 solution's pricing lacks transparency."
"The solution is not that expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Cloudflare Zero Trust Platform's pricing is good."
"The prices are slightly 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."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"In my previous organization, avoiding four instances of CryptoLocker within an estimated six month period is approximately $600,000 in lost time and effort. Our five year cost was about a million dollars, and the four outages that we had equated to 65 percent of that five year cost."
"It is a reasonably priced solution."
"As per market availability, this solution is more expensive than other vendors."
"The price is significantly high."
"It is an expensive product. I rate its pricing an eight or nine."
"We were using Proofpoint and then we switched to Cisco... reportability was one of the main reasons we switched, but the biggest one was cost. If you can get an equivalent functionality for a better price it's wise to do so. That's what our primary decision came down to: We could get equivalent functionality at a lower price point."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"Online Protection is fairly expensive."
"The tool's pricing is excellent."
"The pricing of the solution is reasonable."
"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 price of Microsoft Exchange Online Protection is reasonable."
"The solution is priced high and could be less expensive compared to other solutions."
"The product is bundled with Microsoft 365."
"The solution should reduce the cost."
