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

"Enables me to work from two locations."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"It will take the blow rather than our applications should an attack occur."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"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."
"Cloudflare Access is part of the Zero Trust philosophy."
"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."
"For what you get for the product, the support, and the overall stability, it is definitely a good return on investment."
"Cisco's Secure Email integrates with Cisco Firewalls, utilizing the AMP as their anti-malware engine, which allows for information sharing between devices."
"It does a great job of preventing spam, malware, and ransomware. I can only go by what people have told me and what I've seen, but I have not seen spam in a year and a half to two years in my own company mailbox. And there are not a lot of catches where it's catching something that should have gotten through, either."
"We chose Cisco Iron Port as it delivers strong email security protection and our company needed it to protect the company's email systems from spam, email viruses, .exe files, unwanted email from unwanted sender etc."
"The return here is more security and fewer interruptions; it's more stability and productivity versus less productivity, and you could say that you're minimizing your costs by $65,000."
"It does a great job of preventing spam, malware, and ransomware."
"Capital expenditure is a significant consideration, and the impact on major expenditures prompts a careful analysis before onboarding the new product."
"The security features are valuable."
"We use the solution to receive emails. We do not use the calendar function as our clients are slow adaptors to the latest features."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"You can use the product to create special accounts."
"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."
"Online Protection's most valuable feature is its admin interface."
"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
"We can migrate seamlessly without any disruptions to our operations."
"It has a really nice web-based administration console."
 

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Cloudflare DDoS has poor technical support."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"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."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"I use the search all the time. Sometimes, it is hard to search for things and things are hard to find. People come to me all the time, saying, "This email didn't get through." Then, I go searching and don't find it on the first search. You have to think about alternative searches. I don't know if there is an easier way that they could help to find things. I don't know how they could simplify it, because now everybody else is using the cloud and everything is coming from Office 365, or whatever. It is just not the same environment from years ago where everybody had their own server and you could search easier."
"The tool's pricing can be improved."
"The area of license renewal should be improved. We normally renew our license every year."
"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."
"Having Cisco Email Security as a standalone solution is not good enough. It needs to be combined with another solution."
"The scalability must be improved."
"Licensing is quite complicated for a number of customers, including ourselves."
"The hardware is not up to the mark. Two to three times a year we have complete downtime."
"The tool is not 100% stable."
"The product needs more granularity. Some features, like encryption, are not available."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"The security features could be better and more secure in the next release."
"The licensing can be on the expensive side, especially in the cloud space."
"The product could be more stable. Microsoft products could be more stable because sometimes, even though they are updating some things, we cannot find those updates."
"The solution must improve the user experience."
"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."
 

Pricing and Cost Advice

"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 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."
"The prices are slightly expensive."
"The solution is not that 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 solution's pricing lacks transparency."
"There were no other costs in addition to the standard licensing fees."
"It is an expensive product. I rate its pricing an eight or nine."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"Cisco Secure Email is expensive, but we get what we pay for."
"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."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"It is a super big router that costs a few hundred thousand dollars."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"The price of Microsoft Exchange Online Protection is reasonable."
"Apart from the license fee for the solution, there are no additional costs."
"The product's pricing is competitive for the US market."
"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 price could be lower."
"The solution is priced high and could be less expensive compared to other solutions."
"The pricing of the solution is reasonable."
