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.

Clawback feature performs well but analytics and integration capabilities need improvement

The integration capability with other threat intelligence platforms is not optimal, as I have experienced difficulty in sending logs to our SIEM. Cisco Secure Email Threat Defense's flexibility could be enhanced while it mostly integrates with cloud solutions, but not on-premise. 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. Regarding room for improvement, the significant number of false positives should be addressed. The solution does not adapt to behavioral analytics and does not make changes when it sees a pattern.

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 mitigates DDoS attacks."

"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 is simple to use."

"The blocking feature is very good."

"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."

"Cloudflare is simple to use."

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

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

More Cloudflare One pros

"Regarding stability, Cisco Secure Email Threat Defense is very stable."

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

"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."

"This solution is easy to use."

"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."

"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."

"Cisco Secure Email Threat Defense's best features include user management of graymail, enhancing security awareness by allowing users to manage cold calls, sales-based items, and ensuring email compliance."

More Cisco Secure Email Threat Defense pros

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

"The most useful feature of this solution is to share files with external parties and we can use this functionality to share files internally too."

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

"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."

"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."

"Kiteworks is easy to manage and maintain with a user-friendly interface and I recommend it to anyone that requires a file-sharing system that supports SFTP."

"The solution can be used remotely; it's easy to upload and share files."

More Kiteworks pros

Cons

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

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

"Our customers no longer use Cloudflare because its service is subpar."

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

"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."

"Our customers no longer use Cloudflare because its service is subpar."

"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 response time for support must be reduced."

More Cloudflare One cons

"The solution is a bit expensive."

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

"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."

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

"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."

"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."

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

"The pricing could always be better."

More Cisco Secure Email Threat Defense cons

"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."

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

"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."

"There is no offboarding process for end-users in Kiteworks. It's a manual process. There is no automated syncing with LDAP and checking to see if the account is still active. It's a manual process to get people out of here, which isn't the best way."

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

"File location could be improved."

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

"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

"The solution is not that 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."

"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 prices are slightly 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 solution's pricing lacks transparency."

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

"The solution’s pricing is manageable."

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

"It is expensive compared to other vendors."

"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."

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

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

"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."
