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.

Clawback feature performs well but analytics and integration capabilities need improvement
The integration capability with other threat intelligence platforms is not optimal, as I have experienced difficulty in sending logs to our SIEM. Cisco Secure Email Threat Defense's flexibility could be enhanced while it mostly integrates with cloud solutions, but not on-premise. The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious. Regarding room for improvement, the significant number of false positives should be addressed. The solution does not adapt to behavioral analytics and does not make changes when it sees a pattern.

Targeted email filtering has reduced spam and phishing and now saves significant investigation time
The best features of Fortinet FortiMail include its techniques and tactics, which are highly effective compared to other solutions such as Microsoft 365. Although Fortinet FortiMail may not be as advanced in some aspects, it is well recognized for its strong performance in handling spam and phishing. It performs thorough mail scanning and also offers a sandboxing feature that enhances protection. Fortinet FortiMail has had a positive impact on my organization by significantly reducing unwanted email activities such as spam and phishing. It provides accurate detection and generates results that often exceed what can be achieved through manual analysis. Since deploying Fortinet FortiMail, I have observed a reduction in investigation time by at least 20 to 30 percent.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Cloudflare is simple to use."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare Access is a stable solution."
"Cloudflare is by far the most effective solution that I have come across."
"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."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"The product offers protection, email security, anti-spam, and antivirus."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."
"This solution is easy to use."
"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."
"Cisco's technical support is very good."
"It's very easy to deploy and configure."
"FortiMail is an awesome product mechanically."
"The antiphishing capabilities are very good."
"From our experience with Fortinet FortiMail, we have found that it's a very strong platform for ensuring company security."
"It is a very reliable program and it works great."
"The anti-spam functionality is good and works well."
"The most valuable feature of the solution is the tool's ability to prevent phishing attacks."
"The spam filtering is great."
"The most valuable feature of Fortinet FortiMail is its fully detailed dashboard."
 

Cons

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"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."
"For the topic of improvement, providing some training material is one of my suggestions."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"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 initial onboarding was causing us some confusion."
"Feedback could be enhanced."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"The pricing could always be better."
"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
"We encounter issues while searching for missing emails."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
"Such kinds of things, raised from the point from the objective actually, we are using Fortinet FortiMail. We don't find any kinds of challenge or difficulties, but Fortinet FortiMail is more efficient and more effective for us. I don't know for other client, but for us, Fortinet FortiMail is very effective Like, for instance, if it is possible, let's say some kind of high threat is actually encountered if it could be possible to SMBs in our smartphone, or mobile apps, kinds of thing, if Fortinet FortiMail is available to monitor the thing using from our mobile phone from our smartphone. If such kinds of things are truly included, it will be more or good for us."
"Online support sometimes takes up to a week to get back to you."
"The UI could be better."
"The biggest room for improvement would be the deployment. It will be hard for someone who doesn't understand the interface to deploy. If you understand it, you can find your way around the problems."
"I would like the integration to be easier."
"I think they should improve Fortinet FortiMail on-premises by enhancing its user interface."
"It is not easy to install."
"The sandboxing features are not well done in Fortinet FortiMail, making it an area of improvement."
 

Pricing and Cost Advice

"The prices are slightly expensive."
"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."

"Cloudflare Zero Trust Platform's pricing is good."
"The solution's pricing lacks transparency."
"It is expensive compared to other vendors."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"The solution’s pricing is manageable."
"The feedback from vendors and customer is that it is expensive."

"It's not as that expensive with the competitive different brands. The products sell a lot."
"Pricing is straight-forward and renewable without complicated pricing structures."
"It is an expensive product."
"The tool is very expensive."
