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.

Improves decision-making with clear verdict explanations and works well across multiple environments
I know that a lot of time has been invested in improving the efficacy of the platform, and it shows; it performs very well. Moving forward, I think our focus should be on how to achieve better integration with other systems. While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value. This would allow it to be integrated more closely with the workflows of various teams and could potentially increase its market appeal. From my perspective, the tool itself functions exceptionally well, which gives me confidence in the system. I want to see this functionality extend to other tools that I use, enabling faster automation and improved workflows for the team, particularly from a security operations standpoint. I have no critiques regarding the tool itself. They've done an outstanding job and are maintaining high quality throughout their development process. They have a great product, and it's essential that they continue to uphold that standard, even though it requires significant effort.

Quotes from Members

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

Pros

"Cloudflare is by far the most effective solution that I have come across."
"Enables me to work from two locations."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"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 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."
"Cloudflare, in my opinion, was easy to implement."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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."
"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"The product is easy to deploy and maintain."
"I'm quite satisfied with the graphical user interface for Barracuda products."
"The solution's most valuable feature is impersonation detection."
"The solution is straightforward to set up."
"The main benefits Barracuda Email Protection provides for us are saving time and money because we don't run into any kind of attack or disruption in the mail service that we may face, including ransomware attacks."
"We found Barracuda to be more efficient, easy to use, and customizable."
"The beauty of Barracuda Email Protection is that it is easy to manage and simple to deploy."
"Overall, the auditability and the ability to evaluate the information in Sublime through various mechanisms made me very comfortable with setting these capabilities to auto-remediation."
"I like its ability to detect and block."
 

Cons

"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."
"Cloudflare DDoS has poor technical support."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"For the topic of improvement, providing some training material is one of my suggestions."
"The onboarding process can be improved a little bit."
"Feedback could be enhanced."
"Lacks a VPN feature to provide a secure connection to the data center."
"They can still improve."
"Barracuda Email Protection can be improved by enhancing the reporting feature."
"Barracuda Email Protection needs better reporting and more robust integration with security awareness training platforms and third-party solutions."
"There is room for improvement, particularly in reaching out to technical support during deployment."
"I would like to see some additional functionality in terms of employee monitoring, as part of a work-from-home security solution."
"The solution's reporting mechanism is a little poor and could be improved."
"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."
"The ability for users to look at their own quarantine box needs improvement. So at the moment, it doesn't give you the ability to see every email that has been quarantined. No end-user has the ability to see what's being quarantined. It's only people who have access to the back-end platform that can actually see what has been quarantined. The end user doesn't know if they have an email that has been quarantined, only if they're expecting something that didn't come through."
"While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value."
 

Pricing and Cost Advice

"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."
"The prices are slightly expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"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 solution's pricing lacks transparency."
"Price-wise, this product is middle-of-the-road."
"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."
"The product is expensive."
"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."
"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."
"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 price of Barracuda Essentials is better than some of the competing products."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
