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

"Enables me to work from two locations."

"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."

"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."

"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."

"Clover is the best product globally."

"Cloudflare is by far the most effective solution that I have come across."

"It will take the blow rather than our applications should an attack occur."

"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."

More Cloudflare One pros

"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."

"The features and functionalities are much better than Microsoft's in-built Defender plan, and this product has helped us to protect our organization from any malware attack in the past."

"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."

"It's very easy to deploy and configure."

"On ease of use, it rates very high."

"Secure Email Threat Defense's scalability is good."

"It has an efficient email filtering feature."

More Cisco Secure Email Threat Defense pros

"FortiMail is a stable product."

"This is a very stable product and all of our customers are happy that we use it."

"The features I find most valuable in Fortinet FortiMail include its robust security and ease of use."

"The number of false positives is minimal."

"These days, the threats by email are very high, and this solution provides our security."

"Fortinet FortiMail's most valuable features are its performance and security."

"The user quarantine feature in the solution is good...It is a stable solution."

"FortiMail has a low cost and high support."

More Fortinet FortiMail pros

Cons

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."

"The response time for support must be reduced."

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."

"They don't have a person to provide support for customers using the solution under their free plan."

"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."

"The onboarding process can be improved a little bit."

"The tool should provide on-premise versions. Currently, all versions are cloud-based."

"Feedback could be enhanced."

More Cloudflare One cons

"We encounter issues while searching for missing emails."

"The search area has room for improvement."

"The pricing could always be better."

"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."

"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."

"This solution could be improved by integration with Sandbox."

"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."

More Cisco Secure Email Threat Defense cons

"The security products stop their operations once the subscription period expires. It is a wrong policy. If I trust a product, it has to continue working even after expiry. It should have a grace period of 30, 40, or 60 days. We can extend the subscription during those days. In some places, subscription extensions can take up to six weeks. During the renewal process, the support offered by the company is very poor. It also reduces security. We pay for the expired period but do not get protection during those times. The user of Fortinet FortiMail should have a feature to see spam names."

"I think they should improve Fortinet FortiMail on-premises by enhancing its user interface."

"The tool needs to improve its pricing policy. Also, it needs to be more user-friendly. I would want it to improve email security as well."

"The solution's pricing is flexible and can be adjusted for African utility companies. Microsoft often offers special pricing formulas for African governments and organizations and it is similar to Fortinet FortiMail. In my country, government institutions receive discounted pricing from Fortinet FortiMail."

"I would like it if the solution could be more affordable."

"Header inspection and containerization, like on-prem premises sandboxing, need enhancement."

"The support could be faster because we've been receiving complaints from customers, they say that when they raise a ticket, it doesn't take 24 hours to respond, sometimes the support responds after three days. This is a lot of time."

"The solution doesn't scale easily."

More Fortinet FortiMail cons

Pricing and Cost Advice

"The solution's pricing lacks transparency."

"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."

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

"The solution is not that expensive."

"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."

"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 is expensive compared to other vendors."

"Price-wise, the solution is not far from Microsoft ATP. So, it is affordable."

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

"The price is acceptable for the support license it includes."

"Fortinet Fortimail has reasonable pricing."

"Fortinet FortiMail is a little bit expensive."

"The fees for Fortinet FortiMail can be complicated. However, overall the pricing is fair."

"There is a license required for this solution."

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