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.

Have raised concerns about scanning engines and automation while continuing to rely on layered protection strategies

Incident response is something that requires more development from Barracuda's side. Regarding room for improvement for Barracuda Forensics and Incident Response, for the product, developing or improving the scanning engine is important, but it's a bit tricky. I know that they are working on it heavily. The difference between Barracuda and Sophos is Sophos focused heavily on cybersecurity while Barracuda tried to increase their product portfolio. Sometimes, in some cases, this might end up with their teams being unfocused or a bit thin and stretched and super busy. However, there is room for improvement. The product is great. The teams that are supporting are great. But there is always room for improvement. Even if you have a product that you would give a rating of 10 out of 10, there is always room for improvement. The day we stop improving is the day we die. Regarding the scanning engine, Barracuda Forensics and Incident Response has a very good feature where you can create automated flows for how to handle specific emails that are detected as incidents. This needs a bit of an improvement. That's the only component of Barracuda Forensics and Incident Response that I believe requires improvement.

Quotes from Members

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

Pros

"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."

"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 blocking feature is very good."

"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 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."

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

"Clover is the best product globally."

More Cloudflare One pros

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

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

"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 solution is straightforward to set up."

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

"I'm quite satisfied with the graphical user interface for Barracuda products."

"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."

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

More Barracuda Email Protection pros

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

"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."

"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."

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

"The most valuable feature is the straightforward setup."

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

Cons

"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."

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

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

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

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

More Cloudflare One cons

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

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

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

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

"They could simplify the licensing and the pricing."

"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."

"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

"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."

"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."

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

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

"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 solution's pricing lacks transparency."

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

"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 solution is not that expensive."

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

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

"The prices are slightly expensive."

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

"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."

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

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

"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."

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

"The product is expensive."
