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.

Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

Secures email by identifying threats and managing email policies effectively
The intuitive management interface feature makes email security policies very easy to implement as it's all about features that need to be enabled or disabled. Our investigation in any incident or mail is very useful as it provides all details about incoming mails, enabling thorough review and detection. The real-time threat intelligence feature is particularly useful as it detects all kinds of threats identified by incoming mails. The Impersonation license utilizes AI tools. Sometimes some phishing mails are reported as phishing, but they are not actually phishing mails. They are detected due to certain words and languages that appear suspicious but were generated by AI tools. Everyone or an advisor may use it for their own purpose or learning, even though it indicates that the mail detected is phishing when it's not.

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, in my opinion, was easy to implement."
"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 One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."
"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Avanan is a stable software. My company hasn't faced any issues, bugs, or problems with the performance of Avanan."
"Email inspection has saved many employees from spam attacks and viruses from unauthorized sources."
"The program has reduced the dangers related to phishing, malware, ransomware, and other vulnerabilities."
"In the overall experience, I have come to conclude that Avanan has the best email management tools that can prevent cyber attacks."
"Avanan Cloud Email Security has empowered teams with modern data security management knowledge and provided enough awareness that helps employees to prepare for any outcomes."
"Email Attachment Protection detects any insecure files and quickly blocks them to prevent the spread of viruses to other secure documents."
"Prevention of account takeover by ransomware attackers has solved long-term problems that had become normal in the company."
"Avanan is just outstanding on how efficient and effective their learning modules are to pick up on these different pieces."
"It can scale."
"The most valuable feature is the Antispam services, which are the basic services of a spam device."
"The solution helps us to block some blacklisted emails."
"My current company had no product before Barracuda, and we get a lot of added value from the various things it does, ranging from advanced threat protection and spam filtering to protection from viruses and email spoofing, plus cloud-to-cloud backup."
"The feature that sets Barracuda apart from other solutions is the Office 365 cloud-to-cloud backup."
"I appreciate that the product provides account takeover protection."
"This solution has helped to significantly reduce the amount of junk email that we receive."
"If you want to secure your network then you must acquire a spam filter and virus firewall; in my opinion, Barracuda is the best choice."
 

Cons

"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."
"Our customers no longer use Cloudflare because its service is subpar."
"Cloudflare DDoS has poor technical support."
"Feedback could be enhanced."
"For the topic of improvement, providing some training material is one of my suggestions."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"They should come up with a mobile application so that it can be more flexible."
"The cost can be reviewed to enable SMEs to acquire it and enjoy great security features."
"The email filtration system is not well set since it sometimes blocks useful emails that are safe."
"It should also offer a quick backup in case any email is wrongly quarantined or deleted to ensure no data loss."
"Familiarization with performance for new teams may take a long time."
"Integration with various SaaS offerings, who are leading in the SaaS market. Examples include: SNOW (ServiceNow), Salesforce.com"
"It should reduce the amount of time needed for thorough scanning."
"Email querying is not efficient throughout."
"Spam is not always detected, and it should be more automated. We have seen that some emails are allowed by these emails, which are then stopped by Microsoft."
"My customers were sending OPT bulk emails and Barracuda Email Security Gateway was not able to handle it. We have to go with another different solution, such FortiMail for the task. We are implementing these combinations of the Barracuda and FortiGate, for email security. The FortiGate FortiMail security gateway we use to send only the bulk email, not for receiving emails."
"The solution should add automatic alerts to the mobile."
"There are some times when legit emails are trapped on Barracuda and we are unable to get that information unless we actually log on to the network to find out."
"The deep scanning feature needs to be improved."
"The pricing of this solution could be improved."
"Regarding real-time intelligent features of the Barracuda Email Security Gateway, some spam emails are still being released by the ESG to the end users, so the functionality is not working appropriately."
"The solution could improve by adding DomainKeys (DKIM) functionality. This is something that is essentially required nowadays for outbound security. They do not have it on their on-premise solution appliance but they have alternate arrangements for their cloud solution."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution's pricing lacks transparency."
"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."
"The pricing is somewhere in the middle. I would rate the pricing a seven 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."
"Good pricing arrangement as an SaaS offering."
"Having the flexibility and modeling to do the pricing that best fits the needs of the organization is incredibly ideal. That is what Avanan does. They know exactly how many users are using it, etc. We can tune the invoicing associated with how we are using the product so we can charge it back to the shows appropriately."
"The product is not the cheapest in the market."
"Avanan’s price is comparable to Barracuda."
"The pricing of Avanan is reasonable."
"The licensing fees are part of a bundled support package that we pay for."
"The solution requires a license and we pay annually."
"The licensing cost is competitive, it's not too high and not too low."
"We find the solution's pricing okay."
"Barracuda Email Security Gateway is a cost-effective solution."
"The regular pricing was initially very reasonable, but three years ago, Barracuda revised their price list and SKUs, resulting in a significant doubling of the standard prices."
"We pay between $8 and $10 USD per user per month."
"The pricing for the product is fine."
