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.

Has faced challenges with configuration, taking actions, and learning curve but benefits from centralized management and good technical support

We have deployed Cisco Secure Email Threat Defense in two customer environments. It is still in development as a new product. Some customer requirements, such as sending logs to a Syslog server, are limited as ETD only supports sending audit logs. Customers have requirements for other system logs as well, which should be developed from their side. Another customer request is to restrict the IPs that can log in, which cannot be done from Cisco Secure Email Threat Defense yet. Any user with login details can log in. We can restrict the IPs in Cloud Mail Gateways, but not from Cisco Secure Email Threat Defense. It would be beneficial to improve this feature. Cisco Secure Email Threat Defense can take actions, such as requesting O365 to quarantine mail. In that case, the customer requires notification to the recipient from Cisco Secure Email Threat Defense. This option would be valuable if available. The real-time threat intelligence of Cisco Secure Email Threat Defense is an AI-based classification. It took one to two months to optimize the classification, but we still experience some false positives. Reducing the learning period would be beneficial. The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned. Reducing the learning time would be much better. Additional features desired in the next release include IP restrictions and user logging IP restrictions, ensuring only the customer environment can log in to Cisco Secure Email Threat Defense. Logs forwarding needs improvement as currently it only has audit logs. In Cloud Mail Gateway, we can create an IPsec tunnel to forward logs. However, in Cisco Secure Email Threat Defense, there is no option, and we must do API integration to send logs. Only SIM can get logs; Syslog cannot retrieve them.

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."

"The blocking feature is very good."

"Enables me to work from two locations."

"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 DDoS mitigates DDoS attacks."

"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."

"Clover is the best product globally."

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."

More Cloudflare One pros

"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 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."

"Regarding stability, Cisco Secure Email Threat Defense is very stable."

"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."

"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."

"The product offers protection, email security, anti-spam, and antivirus."

"Cisco's technical support is very good."

"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."

More Cisco Secure Email Threat Defense pros

"The product helps users handle security challenges as it offers prefiltering options and does relatively good incident reporting."

"Fortinet FortiMail is rated an eight for the protection and features it provides in the on-premises setup."

"The most valuable feature of the solution is the tool's ability to prevent phishing attacks."

"Through Fortinet FortiMail, we can perfectly authenticate each local mail service and mail release so that only authenticated mail goes out from our domain."

"After implementing FortiMail, the spam, and malicious emails we receive have significantly reduced, making it much simpler to manage."

"It is a scalable solution."

"Both logging and reporting are very good, as well as the antivirus profiles, content emails, content profile, and application profile."

"We do have, as of late, spam outbreaks, and this solution has been pretty reliable in dealing with them."

More Fortinet FortiMail pros

Cons

"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."

"The initial onboarding was causing us some confusion."

"The software has automated alerts, but the automated alerts are not available in the mobile app."

"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."

"Our customers no longer use Cloudflare because its service is subpar."

"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

More Cloudflare One cons

"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."

"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."

"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."

"The solution is a bit expensive. It could be cheaper."

"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 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."

More Cisco Secure Email Threat Defense cons

"Fortinet FortiMail can be improved in terms of its dashboard, which is small and not visually appealing, making deeper investigations difficult."

"ortiMail has some latency issues and sometimes takes time to receive emails."

"The dashboard is small, it doesn't have a huge dashboard that you can rely on, you need another application to work with it, which is why they created FortiAnalyzer."

"I believe there is room for enhancement in content and web security features."

"The infrastructure could be improved. The data leak prevention could also be better."

"The only drawback to this solution is that the firmware is frequently updated, and each update results in downtime."

"Issues with the current email search functionality."

"The IDE feature in Fortinet is not as good as the rest of the product because it's very difficult to deploy it."

More Fortinet FortiMail cons

Pricing and Cost Advice

"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 solution's pricing lacks transparency."

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"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 prices are slightly expensive."

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"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."

"It is expensive compared to other vendors."

"The solution’s pricing is manageable."

"The feedback from vendors and customer is that it is expensive."

"It is reasonable."

"You need to pay additional fees for premium support."

"Price-wise, you get what you pay for in Fortinet FortiMail. Apart from the licensing costs, no additional expenses are attached to the solution's pricing."

"In terms of licensing, we are using a virtual machine license for the single virtual server which it runs on. Doing it this way enables us to cut costs by only licensing FortiMail for our exact use case. If you need to expand in future, you can later buy extra licenses per virtual machine."

"The solution is quite pricey compared to other competitors in the market."

"There is a license required for this solution and it is on an annual basis. I am satisfied with the price."

"If you don't need the full bundle that includes everything, you have options for the small or medium enterprise environments."

"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."
