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.

Quotes from Members

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

Pros

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

"The solution has different options that can be used to differentiate DDoS attacks."

"Clover is the best product globally."

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

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

"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."

"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 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."

More Cloudflare One pros

"The archiving and search features are very good."

"When we got the service, it included the email archiver with unlimited storage."

"The most valuable features are security and ease of use."

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

"I would rate the solution nine out of ten."

"The beauty of Barracuda Email Protection is that it is easy to manage and simple to deploy."

"The most valuable aspect includes attempts to spoof or compromise domains from external sources."

"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."

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

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

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

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

Cons

"The software has automated alerts, but the automated alerts are not available in the mobile app."

"The response time for support must be reduced."

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

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

"Lacks 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."

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

"For the topic of improvement, providing some training material is one of my suggestions."

More Cloudflare One cons

"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."

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

"Barracuda Email Protection needs better reporting and more robust integration with security awareness training platforms and third-party solutions."

"Customers chose a different product after experiencing a problem when they upgraded the firmware, which caused the system to restart multiple times during working hours."

"The product must enable bulk user management."

"Two to three months back, we got fraudulent emails in which someone in the organization was being blamed."

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

"They could simplify the licensing and the pricing."

More Barracuda Email Protection cons

"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."

"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."

"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."

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

Pricing and Cost Advice

"The prices are slightly expensive."

"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's pricing lacks transparency."

"The solution is not that 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 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 product is expensive."

"Price-wise, this product is middle-of-the-road."

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

"The price is similar to that of Microsoft 365."

"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 solution's pricing is moderate, where it is neither cheap nor expensive."

"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."

"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."

More Barracuda Email Protection pricing and cost advice

"The solution is not expensive."

"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
