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

"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare Access is a stable solution."
"Cloudflare is simple to use."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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."
"It is a stable solution."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"The product offers protection, email security, anti-spam, and antivirus."
"Cisco Cloud Mailbox is used for copying emails, anti-spamming, and securing the company's email, and we really enjoy the anti-spamming capabilities as well as the rejecting of bulk emails, which we can customize by adjusting the variables, and it is very user-friendly."
"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."
"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."
"This solution is easy to use."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"On ease of use, it rates very high."
"Fortinet FortiMail's most valuable features are antispam, antivirus, database, and data loss prevention (DLP)."
"The product's initial setup phase was very easy."
"When combining this solution with other Fortinet products, such as FortiGate, it integrates well and provides a comprehensive protection package."
"The GUI isn't hard to use. When we do a demo and explain the features of Fortinet products to our customers, they understand very quickly. They can easily manage their systems without us."
"It is a very reliable program and it works great."
"FortiMail is a stable product."
"The features I find most valuable in Fortinet FortiMail include its robust security and ease of use."
"FortiMail possesses notable strengths, and one key feature is its store-and-forward concept."
 

Cons

"Cloudflare DDoS has poor technical support."
"Our customers no longer use Cloudflare because its service is subpar."
"The onboarding process can be improved a little bit."
"Feedback could be enhanced."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The response time for support must be reduced."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"For the topic of improvement, providing some training material is one of my suggestions."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market."
"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."
"This solution could be improved by integration with Sandbox."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"We encounter issues while searching for missing emails."
"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."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools."
"They should add a lot of threat-intelligence feeds from different sources - not only from one source (FortiGuard)."
"My customers frequently ask to have detailed documentation for FortiMail and FortiWeb as they have in FortiGate. What they currently have is not enough."
"High Availability needs improvement."
"The solution is user-friendly to a degree but the dashboard needs improvement."
"Maybe FortiMail's integration could be better."
"I don't know if it is possible, but I would like to see Artificial Intelligence and machine learning introduced."
"The main area for improvement is the pricing."
"The logging information is sometimes not clear or easy to understand."
 

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's pricing lacks transparency."
"The prices are slightly expensive."
"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 is not that expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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 feedback from vendors and customer is that it is expensive."
"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 tool is very expensive."
"It is an expensive product."
"We paid approximately $30,000 for the solution. It is less expensive than some other solutions. We have one license that carries all the features that we wanted."
"Fortinet FortiMail is a little bit expensive."
"The pricing is on the higher side."
"The product's licensing part depends on the number of mailboxes and the hard disk needed by customers. The cost of the license depends on the number of mailboxes and the number of emails."
"Fortinet FortiMail is inexpensive."
"FortiMail has extra charges for installation, configuration, and project management."
