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.

Improved email security has reduced spam, simplified encrypted mail, and strengthened user trust
The best features Barracuda Email Protection offers include good spam filtering and very good sandboxing of all links, as well as good encryption. It also has integrated logging for user management of their own spam. It has better filtering technology, so few are false positives as well, with excellent anti-spam engines and logging. It is extremely easy to install, configure, and set up, and there is excellent message tracking for folks that say they have not received an email they were expecting. Integrated logging and user management make my daily work easier because it is very easy to log in and to manage this tool, hence making it a very good tool for email protection. It also has excellent, easy-to-add designated users as site administrators, and it is competitively priced. It has a user-friendly portal, strong cloud-based features, and no additional maintenance cost, along with responsive support. Barracuda Email Protection has positively impacted my organization by handling encryption better than any other tool I have used before, which has increased our email protection significantly. Our security has also increased from forty percent to sixty-five percent, especially when dealing with all the threats that come through emails. It has been a great tool because we can handle email delays and delays on file scanning. When our partners are happy, we are very happy, and it has helped us have less time chasing bad emails. The fast implementation of encrypted mail keeps employees working with less interruption since they are happy, satisfied, and secure.

Provides reliable real-time email protection and offers competitive pricing features
Regarding Kaspersky Security for Mail Server, I have not compared with other solutions, but I will compare and provide feedback. It is a reliable and fast security solution, and I can say it blocks better than other competitor software. Kaspersky Security for Mail Server has support for Windows and Linux, but regarding improvement, I have to dig deep and will have to do research on that. I have not checked into much detail about what can be better in Kaspersky Security for Mail Server. I have checked in general. If given some time, I can check and compare with other solutions. Regarding Kaspersky Security for Mail Server, I have found this is quite a good solution. It has a good response and good detection capability. I have not checked other products, so I cannot give any detailed or specific feedback regarding that. From what I have checked from Kaspersky mail security, it is satisfactory.

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."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare DDoS mitigates DDoS attacks."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"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."
"The blocking feature is very good."
"Cloudflare Access is part of the Zero Trust philosophy."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"At the moment, I am working with Sophos Cloud, Sophos Intercept X; when they introduced the XDR, we used it, and then when they introduced the Optix, we used it, and then we upgraded our subscription with them to MDR, so we are now utilizing Sophos Cloud Central MDR."
"The solution's most valuable feature is impersonation detection."
"This is one of the easiest, safest, and most secure solutions for security and email archival."
"When we got the service, it included the email archiver with unlimited storage."
"I'm quite satisfied with the graphical user interface for Barracuda products."
"Barracuda Email Protection has positively impacted my organization by increasing our email protection and security significantly, with our security increasing from forty percent to sixty-five percent, especially when dealing with all the threats that come through emails."
"The most valuable aspect includes attempts to spoof or compromise domains from external sources."
"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"With both of them working together, we have the perfect solution for mail."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
 

Cons

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The onboarding process can be improved a little bit."
"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."
"Feedback could be enhanced."
"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 customer service and support could be improved if the support were available directly in Europe. Currently, the support is often managed from India, so we sometimes need to wait due to the time zone difference. It would be quicker and better if the support were provided by European staff."
"Barracuda Email Protection needs better reporting and more robust integration with security awareness training platforms and third-party solutions."
"Barracuda Email Protection can be improved by enhancing the reporting feature."
"There is room for improvement, particularly in reaching out to technical support during deployment."
"I wish the interface of Barracuda Email Protection could have worked in a more responsive way, as sometimes I feel it is slow or laggy when I try to interact with it."
"The platform's pricing needs improvement."
"The licensing and pricing need to be improved."
"The technology works on a supervised engine, but it would be better if it ran on an unsupervised engine."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"The solution is not 100 percent stable and that can use improvement."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
 

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."
"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 solution's pricing lacks transparency."
"The prices are slightly expensive."
"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 solution's pricing is moderate, where it is neither cheap nor expensive."
"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."
"The price is similar to that of Microsoft 365."
"We pay annually. They never charged us for anything else. And they were quite a bit under that $20,000 mark. It was $19,074. And they've been pretty good about not skyrocketing the price or anything like that. It has gone up. It's gone up to $24,000 in 2020."
"Price-wise, this product is middle-of-the-road."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a seven out of ten."
