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.

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.

Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.

Quotes from Members

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

Pros

"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"The blocking feature is very good."
"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."
"Cloudflare, in my opinion, was easy to implement."
"Cloudflare is simple to use."
"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 Access is part of the Zero Trust philosophy."
"I'm very satisfied with the environment and the dashboard."
"Its threat detection capabilities have been beneficial."
"The most valuable feature of the solution is the tool's ability to prevent phishing attacks."
"The most valuable feature of the solution is its interface, allowing users to get around the solution easily. The integration capabilities in the solution are also very easy."
"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."
"FortiMail is a stable product."
"FortiMail effectively filters all emails coming to our mail server, blocking malicious ones automatically."
"The most valuable features of this solution are anti-spam, sender reputation, and antivirus."
"The technical support is excellent."
"It has a really nice web-based administration console."
"It is scalable."
"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."
"The solution's stability is very, very good. I didn't face any problems in the last year."
"The initial setup was easy. The configuration process is very straightforward."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"The security features provided by Microsoft are robust."
"I rate Microsoft Exchange Online Protection (EOP) nine out of ten."
 

Cons

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Operating and tuning the product is difficult."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Feedback could be enhanced."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"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 tool should provide on-premise versions. Currently, all versions are cloud-based."
"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."
"The only drawback to this solution is that the firmware is frequently updated, and each update results in downtime."
"My company pays around 28.000 Egyptian Pounds per year for this program. It is rather expensive in my opinion."
"The product should work on licensing and provide more detail once the license is selected for the customer."
"I would like the integration to be easier."
"Fortinet FortiMail should allow more flexibility with the content rules."
"The solution lacks to provide more visibility when there is a problem, and it needs to be tracked."
"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."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"Besides price, the main room for improvement includes the sandbox or something similar; the usability that solutions are focused on."
"The solution must improve the user experience."
"The product needs more granularity. Some features, like encryption, are not available."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"The price could be lower."
"The reporting needs a little bit of improvement."
