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.

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

"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."

"Enables me to work from two locations."

"Cloudflare DDoS mitigates DDoS attacks."

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

"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."

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

"It will take the blow rather than our applications should an attack occur."

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

More Cloudflare One pros

"Barracuda Email Protection has positively impacted our organization because we rely on it to stop spear-phishing and phishing overall, enabling us to conduct our business securely."

"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."

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

"Barracuda Email Protection has positively impacted my organization by increasing our email protection and security significantly, with our security increasing from forty percent to sixty-five percent, especially when dealing with all the threats that come through emails."

"At the moment, I am working with Sophos Cloud, Sophos Intercept X; when they introduced the XDR, we used it, and then when they introduced the Optix, we used it, and then we upgraded our subscription with them to MDR, so we are now utilizing Sophos Cloud Central MDR."

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

"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."

"The solution is straightforward to set up."

More Barracuda Email Protection pros

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

"The features and functionalities are much better than Microsoft's in-built Defender plan, and this product has helped us to protect our organization from any malware attack in the past."

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

"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."

"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."

"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."

"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."

More Cisco Secure Email Threat Defense pros

Cons

"They don't have a person to provide support for customers using the solution under their free plan."

"For the topic of improvement, providing some training material is one of my suggestions."

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

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

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

"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."

"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."

More Cloudflare One cons

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

"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."

"The product must enable bulk user management."

"Customers chose a different product after experiencing a problem when they upgraded the firmware, which caused the system to restart multiple times during working hours."

"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."

"The customer service and support could be improved if the support were available directly in Europe. Currently, the support is often managed from India, so we sometimes need to wait due to the time zone difference. It would be quicker and better if the support were provided by European staff."

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

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

More Barracuda Email Protection cons

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

"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 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."

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

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

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

"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."

"The solution is a bit expensive."

More Cisco Secure Email Threat Defense 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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The prices are slightly expensive."

"The solution is not that expensive."

"The solution's pricing lacks transparency."

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

"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."

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

"The product is 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."

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

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

"Barracuda licensing model is good."

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

More Barracuda Email Protection pricing and cost advice

"It is expensive compared to other vendors."

"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."
