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

"Clover is the best product globally."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare is by far the most effective solution that I have come across."
"The solution has different options that can be used to differentiate DDoS attacks."
"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."
"Cloudflare Access is a stable solution."
"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."
"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."
"This product is the complete solution and the real deal."
"The tool's most valuable feature in preventing security breaches revolves around the area of malware protection that the product provides."
"There were detailed logs available. That was a seriously good feature... It turns out these were actually spoof emails that came into our environment. I got to know about them from the log system."
"Cisco's Secure Email integrates with Cisco Firewalls, utilizing the AMP as their anti-malware engine, which allows for information sharing between devices."
"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 tool has a DLP solution which we can implement. Its database is updated regularly."
"The product's initial setup phase was easy."
"It does a great job of preventing spam, malware, and ransomware."
"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."
"We like the holding facility that is available for potentially suspicious URLs, which allows a real-time review to be performed before the email reaches a user's inbox."
"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."
"The scalability is pretty good; it does what it is supposed to do."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"The email policy configuration options in Microsoft EOP are satisfactory."
 

Cons

"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"The response time for support must be reduced."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"They don't have a person to provide support for customers using the solution under their free plan."
"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."
"Cloudflare DDoS has poor technical support."
"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."
"The onboarding process can be improved a little bit."
"We have been struggling in the last month with Cisco encryption and with the S/MIME encryption. I don't know if it is an issue on our side or if these features of the solution are not working very well."
"If you are not a technical guy, it is hard to maneuver, but as soon as you work on it, it gets better and better. If there was a better way to know how to do things or how to find things, it would be good."
"I would like to see features like AI since it is currently an area that the product lacks."
"Cisco is already providing a very good environment with the IronPort solution, but there could be some more integration with other products. For instance, an integration with the EDR solution could be there to raise an alert."
"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam."
"Having Cisco Email Security as a standalone solution is not good enough. It needs to be combined with another solution."
"The graphical user interface is not user-friendly like other vendors. I find it very difficult at times to find some options on the UI."
"The solution needs to improve its backup."
"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."
"I think the implementation could be more streamlined."
"Our Exchange system is very locked down and secure, yet we still got hacked."
"Besides price, the main room for improvement includes the sandbox or something similar; the usability that solutions are focused on."
"The product's end-of-life cycle could be extended."
"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."
"The tool's classification for bulk email is cumbersome."
 

Pricing and Cost Advice

"The prices are slightly expensive."
"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"The solution is expensive."
"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."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"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."
"The price is significantly high."
"It is a relatively expensive option compared to other alternatives."
"Cisco Secure Email is expensive, but we get what we pay for."
"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."
"The product is expensive."
"It's a high price."
"The price of Microsoft Exchange Online Protection is reasonable."
"The solution falls on the higher or more expensive side of the spectrum."
"The price could be lower."
"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."
