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.

Pros

"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."
"It will take the blow rather than our applications should an attack occur."
"Cloudflare Access is a stable solution."
"Enables me to work from two locations."
"The blocking feature is very good."
"It is a stable solution."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"I'm very satisfied with the environment and the dashboard."
"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."
"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."
"It has an intuitive, clear graphical interface where you can deploy your policies and understand the overall flow. There are a lot of things that you cannot handle on the graphic interface, like message filters. For this, you need to go to a lower level where you have more power, like command line interface. So, this solution has the best of both worlds. There are not a lot of bells and whistles. It is more practical with access to most features that you can configure."
"Introducing Cisco Secure Email Gateway systems was a set change for us and reduced the number of unwanted emails by a huge factor, a benefit that has continued from when we first got the devices until today."
"Overall, the ease of migration to Cisco's cloud email security from the on-prem solution was a positive experience."
"It's definitely worth looking at Cisco's cloud email security offering; it's surprisingly simple to get going with, it really is easier to use than the on-prem because of everything they have built into it, and it is surprisingly cost-effective."
"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."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"Overall, I think it's really a great product."
"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 initial setup was easy. The configuration process is very straightforward."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"I rate Microsoft Exchange Online Protection (EOP) nine out of ten."
"The solution's stability is very, very good. I didn't face any problems in the last year."
"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 email policy configuration options in Microsoft EOP are satisfactory."
 

Cons

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Our customers no longer use Cloudflare because its service is subpar."
"Our subscription plan for the solution has a limitation of bot signatures."
"The onboarding process can be improved a little bit."
"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."
"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."
"One of the things that Cisco could improve on with IronPort is the support."
"I would rate the stability a six out of ten. We had multiple issues with the stability."
"Better dashboards and more interactive overviews would be nice, but the current functionality is sufficient."
"More than a few steps are required to apply rules and these are not essentially intuitive."
"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."
"The area of license renewal should be improved. We normally renew our license every year. There is a feature called smart licensing, and I switched from the legacy mode to the smart licensing mode because of what I thought smart licensing does. I thought it would make licensing renewal seamless and very swift, but ever since I've switched to smart licensing, each time I want to renew my license, it is a whole lot of headache. The process is not smooth, and I had to keep calling Cisco TAC to see how the issue can be resolved. At one point, I wanted to revert back to the legacy mode, but I can't revert. Once you switch from the legacy mode to the smart licensing mode, you can't revert. They should improve on the visibility of the smart licensing mode so that it can indeed be smart and easier to use for the license renewal every year. That is one challenge."
"My opinion on the licensing of this solution is that it is a mess that needs sorting out. I am not particularly bothered by pricing as I administer it and make recommendations for people to buy or not to buy."
"I am not satisfied with the solution's reporting and logging."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"It kind of has a heavy footprint in terms of an implementation footprint."
"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."
"Microsoft Exchange Online Protection is quite a difficult product."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"The licensing can be on the expensive side, especially in the cloud space."
"The solution must improve the user experience."
"Our Exchange system is very locked down and secure, yet we still got hacked."
 

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 is not that expensive."
"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."
"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"It is a super big router that costs a few hundred thousand dollars."
"The licensing is a mess and needs sorting out. I am not really concerned about the pricing because I only make recommendations, not buying decisions."
"The licensing was all transferred."
"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."
"It is a relatively expensive option compared to other alternatives."
"The price is significantly high."
"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 solution is expensive but is backed by Microsoft's reputation."
"The price could be lower."
"The solution should reduce the cost."
"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."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"The product's pricing is competitive for the US market."
"The product is bundled with Microsoft 365."
"The pricing of the solution is reasonable."
