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

"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare DDoS mitigates DDoS attacks."
"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."
"Cloudflare, in my opinion, was easy to implement."
"Cloudflare Access is a stable solution."
"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."
"It is a stable solution."
"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."
"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."
"It saves a lot of time wasting, for example, phishing attacks distract a user's attention and forged emails waste a lot of time, and this solution helps protect user data."
"Email service is one of the services that we offer at Galaxy, and Cisco ESA has improved our business so much that our customers want to maintain their business with us for email security, with over 500 domains on our email platform and improved profitability in everything."
"We like the in-built features, like the email filtering based on the IP and domain, and Cisco has its own blacklisted domains and IPs, which is very good because this filters around 70 percent of emails from spam and we are seeing fewer false positives with this."
"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."
"The strong point of the solution is that we hardly get any spam emails because of Cisco Secure Email."
"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."
"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."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"Online Protection's most valuable feature is its admin interface."
"It is an easy solution."
"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."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
"You can use the product to create special accounts."
 

Cons

"The initial onboarding was causing us some confusion."
"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."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"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."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Cloudflare DDoS has poor technical support."
"Operating and tuning the product is difficult."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"The tool's pricing can be improved."
"The user interface needs massive improvement. While the device works fine and it's not complicated to write policies, renaming menu items and showing policy flow in conjunction with the application could help."
"Licensing is quite complicated for a number of customers, including ourselves."
"We have Microsoft and we have the E5 licenses, they have more EDR responses on certain emails. That's something that Cisco ESA on the cloud doesn't have. They don't do anything about MITRE attacks. They only detect if there is a malicious email or a threat and they remove it."
"I would like them to add some clustering or high availability features."
"The initial setup was complex because I have two sites with physical clusters."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"I would like more functionality and how to use it for Level 2 type staff. The biggest issue is it needs to be easier to use and navigate."
"Performance and speed should continue to be improved."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
"The security compliance features need to be improved. Sometimes, a client's mailbox becomes full because of retained information and not because of mail. I would like to see improvement in block rules as well."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"The product's end-of-life cycle could be extended."
"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."
"The licensing can be on the expensive side, especially in the cloud space."
"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
 

Pricing and Cost Advice

"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."
"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."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"The solution is expensive."
"There are additional fees for adding features."
"You're going to get what you pay for. If you're not willing to pay the price of Cisco, you're not going to get a product that's as good as Cisco. I don't think Cisco is overpriced, because for the last two years I've been comparing it to Microsoft and Cisco has been cheaper and given us more features."
"It is a super big router that costs a few hundred thousand dollars."
"The product is bundled with Microsoft 365."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"On a scale of one to ten, where one is cheap, and ten is very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
"The product is expensive."
"The tool's pricing is excellent."
"It is a low-price solution."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"It's a high price."
