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

"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."

"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."

"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."

"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 DDoS is better than its competitors for its security, deployment, and scalability."

"Cloudflare is simple to use."

"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."

More Cloudflare One pros

"The archiving and search features are very good."

"We now have a secondary backup of Office 365 that's much easier to retrieve compared to Microsoft. If someone deletes something in Office 365, we can get it back within Office 365, but it's difficult. Barracuda is much easier. There is a lot less management needed using Barracuda. The management becomes much easier for Office 365 and it's no longer on-prem, so there are fewer hours managing on-prem devices, servers, and things of that nature. We don't have network appliances anymore for the backup of our information."

"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 is straightforward to set up."

"The solution's most valuable feature is impersonation detection."

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

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

More Barracuda Email Protection pros

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

"The most valuable feature is the straightforward setup."

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

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

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

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

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

Cons

"Operating and tuning the product is difficult."

"Cloudflare DDoS has poor technical support."

"Lacks 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."

"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."

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

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

More Cloudflare One cons

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

"The platform's pricing needs improvement."

"I would like to see better integration with other products."

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

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

"I would like to see some additional functionality in terms of employee monitoring, as part of a work-from-home security solution."

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

"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."

More Barracuda Email Protection cons

"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."

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

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

"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."

"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."

Pricing and Cost Advice

"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 prices are slightly expensive."

"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The solution is not that 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 solution's pricing lacks transparency."

"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."

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

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

"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."

"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."

"Barracuda licensing model is good."

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

More Barracuda Email Protection pricing and cost advice

"My company makes annual payments towards the licensing costs solution."

"The solution is not expensive."

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

"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
