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.

Enginner at Millennium Information Technologies

Has faced challenges with configuration, taking actions, and learning curve but benefits from centralized management and good technical support

We have deployed Cisco Secure Email Threat Defense in two customer environments. It is still in development as a new product. Some customer requirements, such as sending logs to a Syslog server, are limited as ETD only supports sending audit logs. Customers have requirements for other system logs as well, which should be developed from their side. Another customer request is to restrict the IPs that can log in, which cannot be done from Cisco Secure Email Threat Defense yet. Any user with login details can log in. We can restrict the IPs in Cloud Mail Gateways, but not from Cisco Secure Email Threat Defense. It would be beneficial to improve this feature. Cisco Secure Email Threat Defense can take actions, such as requesting O365 to quarantine mail. In that case, the customer requires notification to the recipient from Cisco Secure Email Threat Defense. This option would be valuable if available. The real-time threat intelligence of Cisco Secure Email Threat Defense is an AI-based classification. It took one to two months to optimize the classification, but we still experience some false positives. Reducing the learning period would be beneficial. The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned. Reducing the learning time would be much better. Additional features desired in the next release include IP restrictions and user logging IP restrictions, ensuring only the customer environment can log in to Cisco Secure Email Threat Defense. Logs forwarding needs improvement as currently it only has audit logs. In Cloud Mail Gateway, we can create an IPsec tunnel to forward logs. However, in Cisco Secure Email Threat Defense, there is no option, and we must do API integration to send logs. Only SIM can get logs; Syslog cannot retrieve them.

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

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

"It is a stable solution."

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

"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."

"Cloudflare Access is part of the Zero Trust philosophy."

"Cloudflare is simple to use."

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

More Cloudflare One pros

"This solution is easy to use."

"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."

"The product offers protection, email security, anti-spam, and antivirus."

"It's very easy to deploy and configure."

"The advanced threat analytics and URL filtering in threat detection are good features that are working well."

"It has an efficient email filtering feature."

"The solution is stable."

"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."

More Cisco Secure Email Threat Defense pros

"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 can identify from which region our users are uploading or downloading files."

"The top two features are the two-factor authentication, which is pretty good. It's easily understood by the users. And their API is rather robust. We have numerous integrations that work off the API."

"It’s a great product that you should seriously consider and take the first step by training."

"The solution removes the limitations with file attachment size that is found with regular email."

"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."

"The solution can be used remotely, including from mobiles, and it's easy to upload and share files."

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

More Kiteworks pros

Cons

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

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

"Feedback could be enhanced."

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

"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."

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."

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

More Cloudflare One cons

"The pricing could always be better."

"The physical appliance has been discontinued, although the platform still exists."

"The solution is a bit expensive. It could be cheaper."

"The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration."

"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."

"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."

"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."

"The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned."

More Cisco Secure Email Threat Defense cons

"Perhaps there could be a notification to users about their bandwidth or network packet loss."

"There are always issues when there are bugs or upgrades. The challenge with upgrading is getting more storage from the customer. Every time we have a new version, it requires additional storage. This means that the customer would need to procure more storage for their server, which they don't like because it means additional cost to them. So, I think my request would be that the version upgrades don't require any significant storage requirement."

"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."

"There is one particular thing that is a nuisance."

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

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

"Kiteworks could benefit from enhancing the proposal knowledge base section, specifically regarding the type of work involved. Currently, the knowledge base seems insufficiently dedicated to this topic, making it challenging for new users to access the relevant administrative law. Improving the visual aids and providing clearer explanations could alleviate this issue."

"The system is extremely stable, but because it is a "COTS" system access is restricted and you must use the solution's support to make even simple changes, which increases the downtime."

More Kiteworks cons

Pricing and Cost Advice

"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."

"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 solution is not that expensive."

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

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

"The solution's pricing lacks transparency."

"It is expensive compared to other vendors."

"The feedback from vendors and customer is that it is expensive."

"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."

"The solution’s pricing is manageable."

"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."

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

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

"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."

"The price of Kiteworks is reasonable."
