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.

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.

Quotes from Members

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

Pros

"Cloudflare, in my opinion, was easy to implement."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"This solution is easy to understand and easy to configure."
"Clover is the best product globally."
"Cloudflare is by far the most effective solution that I have come across."
"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."
"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."
"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."
"I'm quite satisfied with the graphical user interface for Barracuda products."
"The archiving and search features are very good."
"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."
"The most valuable features of Barracuda Email Protection are flexibility and customization."
"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"The solution's most valuable feature is impersonation detection."
"I would rate the solution nine out of ten."
"It has an efficient email filtering feature."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"The solution is stable."
"The features and functionalities are much better than Microsoft's in-built Defender plan."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"I highly recommend it as one of the best choices."
 

Cons

"Feedback could be enhanced."
"For the topic of improvement, providing some training material is one of my suggestions."
"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"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 free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"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."
"The initial onboarding was causing us some confusion."
"Two to three months back, we got fraudulent emails in which someone in the organization was being blamed."
"They could simplify the licensing and the pricing."
"The platform's pricing needs improvement."
"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."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"The policies are set up in Barracuda by default; we don't have any control over them."
"Sometimes, in some cases, this might end up with their teams being unfocused or a bit thin and stretched and super busy."
"There is room for improvement, particularly in reaching out to technical support during deployment."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"The pricing could always be better."
"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"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."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"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."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The solution's pricing lacks transparency."
"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 solution is not that expensive."
"The prices are slightly expensive."
"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."
"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."
"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 is similar to that of Microsoft 365."
"The solution's pricing is moderate, where it is neither cheap nor expensive."
"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."
"The product is 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."
"The feedback from vendors and customer is that it is expensive."
"The solution’s pricing is manageable."
"It is expensive compared to other vendors."
"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."
