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.

Streamlined global file sharing with user-friendly interface and self-service capabilities

I'm not a network expert, however, there must be some room for improvement. Perhaps there could be a notification to users about their bandwidth or network packet loss. If users receive such notifications, they can understand any disruptions are due to issues with their network or bandwidth rather than the site or Kiteworks. Additionally, I work from offshore India, and I told my client manager to communicate with the Kiteworks forum salesman regarding one feature. I noticed the Kiteworks login UI is very basic, lacking customization. Allowing more HTML tags to add hyperlinks or user-friendly information on the home page would be very useful.

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

"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."

"I'm very satisfied with the environment and the dashboard."

"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."

"Clover is the best product globally."

"It is a stable solution."

"It's a perfect solution from my perspective; it's easy to understand and easy to configure."

More Cloudflare One pros

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

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

"I don't see any other email security solution that stacks up against them."

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

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

"The investment in Barracuda Email Protection is quite good for us because we see the value of money on it, as we are saving a lot with Barracuda Email Protection, going from paying close to 300,000 to now sitting at 100,000."

"This is one of the easiest, safest, and most secure solutions for security and email archival."

"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."

More Barracuda Email Protection pros

"The benefits that Kiteworks has provided to its customers in terms of data sovereignty."

"As a file-sharing application, it's an absolute 10 out of 10."

"The best part of this solution is that we can generate multiple reports about how the data is transferred and about user information or IP."

"Scalability is impressive."

"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."

"The most valuable aspect of Kiteworks is undoubtedly the private content network. This feature is particularly beneficial for us. Furthermore, it serves as a centralized platform that enables us to track and manage our information exchange."

"We can see when people are sending things. We can definitely see who is sending to whom. From the administrative logs, we can see who is sending to an outside entity, and those logs are retained for quite a while."

"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."

More Kiteworks pros

Cons

"I would like them to include a VPN feature to provide a secure connection to the data center."

"Feedback could be enhanced."

"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."

"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 free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

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

"The response time for support must be reduced."

"The initial onboarding was causing us some confusion."

More Cloudflare One cons

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

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

"The solution's reporting mechanism is a little poor and could be improved."

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

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

"They could simplify the licensing and the pricing."

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

More Barracuda Email Protection cons

"We mainly had stability issues with kiteworks, where we were pushing the limits of its capability."

"File location could be improved."

"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."

"I would like to see immediate releases of fixes because now it takes at least a week. If that time span can be reduced to one day or two days, that would be very helpful for users so that things are sorted and transactions work smoothly."

"It could be more stable. In the next release, it would be better if it was more stable with improved performance."

"In my experience, their technical support can be a little slow."

"It would be nice if Kiteworks could provide a free version of the platform so that it could be used for a certain number of file transfers. We could be charged a fee if we exceeded the number of allotted file transfers."

"The one feature, which I have also requested directly to Kiteworks, is to have a scheduled upgrade function. Currently, one of my engineers logs in after hours for the upgrade. We're a hospital, and we're 24/7, but the primary users are seven to five. So, we log in the early evening just to push a button to tell it to do the update. It would be nice if that could be very easily scheduled."

More Kiteworks cons

Pricing and Cost Advice

"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 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 prices are slightly expensive."

"The solution is not that expensive."

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

"The solution's pricing lacks transparency."

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

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

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

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

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

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

"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."

"Barracuda licensing model is good."

More Barracuda Email Protection pricing and cost advice

"The license management is changing and confusing. If I could make one change to it, it would be better license management through the API."

"They changed it midstream. We were being charged a certain flat rate for SFTP traffic. For whatever reason, at the beginning of the year, our pricing changed, and we are now being charged more for using a feature of the product than we were when we first bought it. That has been our experience with billing. It turned out to be more expensive than when we started with it."

"The solution is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."

"I believe it's a little costly, but given the faith that we put into it from a security perspective to maintain the integrity of our patient information that is being transferred through this system, that's a small price to pay. So, on the surface, it might look like a lot of money, but depending on the need for security, which is where we feel it shines, it's okay price-wise."

"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."

"The price of Kiteworks is reasonable."
