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

"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."

"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."

"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 Access is part of the Zero Trust philosophy."

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"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."

"This solution is easy to understand and easy to configure."

More Cloudflare One pros

"With Barracuda Email Protection, the features I find most valuable are spam filtering, as it is primarily used for spam protection."

"The most valuable features of Barracuda Essentials are it's a trusted name and is rated very high on review sites. It blocks high percentages of spam and junk email and it's in the cloud. They have hardware appliances, but this is in the cloud. The solution is very effective at blocking malware and blocking spam and this is what we are looking for. There's not a whole lot of complexity, you want a solution that is very good at blocking out all of the unwanted emails."

"The most valuable features of Barracuda Email Protection are flexibility and customization."

"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 best feature of Barracuda Email Protection is that it provides protection for Microsoft 365."

"The main benefits Barracuda Email Protection provides for us are saving time and money because we don't run into any kind of attack or disruption in the mail service that we may face, including ransomware attacks."

"We found Barracuda to be more efficient, easy to use, and customizable."

"The solution is straightforward to set up."

More Barracuda Email Protection pros

"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."

"The most valuable feature is the straightforward setup."

"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."

"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."

"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."

"The integration rate is very high in Kaspersky, which is why most of our customers like it."

"The most valuable features are the anti-phishing and anti-spam capabilities."

"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."

Cons

"The initial onboarding was causing us some confusion."

"Lacks a VPN feature to provide a secure connection to the data center."

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

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

"Our subscription plan for the solution has a limitation of bot signatures."

"Cloudflare DDoS has poor technical support."

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."

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

More Cloudflare One cons

"The technology works on a supervised engine, but it would be better if it ran on an unsupervised engine."

"Barracuda Essentials can improve by continually adding more features."

"The policies are set up in Barracuda by default; we don't have any control over them."

"The solution's graphical user interface (GUI) could be improved visually."

"There is room for improvement, particularly in reaching out to technical support during deployment."

"Barracuda Email Protection can be improved by enhancing the reporting feature."

"The email encryption could be improved."

"Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings."

More Barracuda Email Protection cons

"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."

"The solution is not 100 percent stable and that can use improvement."

"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."

"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."

"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."

"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."

"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."

Pricing and Cost Advice

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

"The solution's pricing lacks transparency."

"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."

"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."

"Cloudflare Zero Trust Platform's pricing is good."

"Barracuda licensing model is good."

"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."

"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."

"The product is expensive."

"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."

"We didn't have to pay a lot for the solution because we got it from a good vendor with a good user volume."

"The price of Barracuda Essentials is better than some of the competing products."
