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.

Provides robust email security features but requires improved modernization and complexity management
Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

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 Access is a stable solution."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare is by far the most effective solution that I have come across."
"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 capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"The solution has different options that can be used to differentiate DDoS attacks."
"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."
"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."
"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. 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."
"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."
"It has an efficient email filtering feature."
"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."
"The product offers protection, email security, anti-spam, and antivirus."
"On ease of use, it rates very high."
"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."
"Its threat detection capabilities have been beneficial."
"It is one of the most efficient solutions in our environment. We have more than nine hundred users. All of these users are protected by Fortinet FortiMail."
"This is a very stable product and all of our customers are happy that we use it."
"The important feature is the application control, which makes administration much easier. It also has an intrusion prevention feature. There's also the wireless functionality, which works well with Huawei devices."
"The most valuable feature of the solution is the tool's ability to prevent phishing attacks."
"Both logging and reporting are very good, as well as the antivirus profiles, content emails, content profile, and application profile."
"I highly recommend the product; the product is easy and there's no complexity, it's easy to use, easy to learn, easy to upgrade, easy to apply any changes, and it offers a good price versus quality balance."
"The biggest implementation my team has done for Fortinet FortiMail was for more than five thousand people, and the most valuable feature was its anti-spam feature."
 

Cons

"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."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"They don't have a person to provide support for customers using the solution under their free plan."
"The initial onboarding was causing us some confusion."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Operating and tuning the product is difficult."
"Our customers no longer use Cloudflare because its service is subpar."
"This solution could be improved by integration with Sandbox."
"The solution is a bit expensive. It could be cheaper."
"The physical appliance has been discontinued, although the platform still exists."
"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."
"We encounter issues while searching for missing emails."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"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."
"Limited ability to upgrade hardware may lead to some performance issues that might otherwise be improved."
"The IDE feature in Fortinet is not as good as the rest of the product because it's very difficult to deploy it."
"Fortinet FortiMail can be improved in terms of its dashboard, which is small and not visually appealing, making deeper investigations difficult."
"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."
"For example, there was malware in some emails that weren't detected in some of the Fortinet FortiMail sessions, but it should have been configured from my company's end to better catch scam emails, but overall, the solution is okay."
"I would like the integration to be easier."
"Online support sometimes takes up to a week to get back to you."
"In my opinion, points for improvement for Fortinet FortiMail include sometimes the speed and fine-tuning the false positive problems, especially with the signed PDF attachments and the whitelist and blacklist."
 

Pricing and Cost Advice

"The solution is not that expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution's pricing lacks transparency."
"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 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 prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
"The feedback from vendors and customer is that it is expensive."
"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 reasonable."
"If you don't need the full bundle that includes everything, you have options for the small or medium enterprise environments."
"You need to pay additional fees for premium support."
"There is either an annual or six-month charge to use this solution. Fortinet FortiMail is cheaper than Proofpoint or Cisco Security, or other email security appliances."
"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."
"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 tool is very expensive."
"Compared to its competitors, Fortinet's products are available at a higher price range."
