Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Anne-Aimee Wollerich - PeerSpot reviewer
Managing bot traffic effectively enhances usability for non-technical users
Barracuda Web Application Firewall lacks some of the more specified and structured features offered by solutions like Tenable. Although Tenable is more expensive and less easily deployable, its features are more deepened and chiseled, particularly for IT personnel. For example, Tenable provides more comprehensive dark web scanning capabilities, which Barracuda could improve upon.
DevenderVannela - PeerSpot reviewer
Ensures efficient traffic management and robust security while simplifying complex configurations
The best features for Microsoft Azure Application Gateway basically protect your application and provide security-related features and also divert the traffic to different instances of your application. I have used URL-based routing, which helps manage traffic efficiency. It is a bit hard to manage in the long run, but it does provide value. I have used the gateway's Web Application Firewall feature, which enhances security as it is the first entry point to your network from the outside world. It helps protect against unwanted requests and other threats that can be configured. Regarding the integration with Azure Active Directory, it helps with authentication processes to configure all the users or the groups. The monitoring capabilities on Azure provide insight into application performance and potential threats because monitoring comes with many products. On Azure, you have Azure Monitor itself to help you monitor the application by collecting data. You have Application Insights and the logging workspace on Azure. By combining these three, you can implement monitoring solutions on Azure applications. Auto-scaling is important because it helps in resource management for customers. Scaling is one of the key features of moving to cloud for any customer. During peak times or special events, such as retail site promotions, user load increases significantly. To address this, based on the number of incoming requests or server capacities such as CPU and memory, you can automatically identify these peak scenarios and configure either scaling up or down automatically based on certain parameters.

Quotes from Members

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

Pros

"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"The most valuable feature of Cloudflare DNS is security."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The most valuable feature is its usability."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"It's very user-friendly."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"Parameter Protection is a valuable feature."
"We run it with no downtime, because it has good support."
"The most valuable feature is the rule set."
"The most valuable feature of this solution is the simplicity of configuration."
"Has a good dashboard."
"The customer service and support are exceptional, and I would give them a ten out of ten."
"It is stable and the performance is good."
"We only need one subscription to be protected against both active DDoS and offline DDoS attacks."
"We use the product in front-end and back-end applications to do the load balancing smartly."
"Microsoft has a vast variety of tools, and it blends very well."
"The health probe is pretty good for your backend health. It tells you whether it's communicating and talking to the endpoint correctly. It is quite useful."
"The most valuable feature is WAF."
"Microsoft Azure Application Gateway gives us a lot of benefits, including domain mapping."
"The simplicity of the solution and its ability to integrate easily with others are its most valuable aspects."
"The most valuable feature of the solution is traffic management."
"Some of the key features of this solution are the low-level maintenance required, floating proxy service, and load balancing."
 

Cons

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"Integration involving API with other products could be more user-friendly."
"The solution could work at being less expensive. It costs a lot to use it."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."
"The pricing could be improved."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"If you know nothing about networks, then you can't set it up."
"It is not stable nor mature."
"Barracuda Web Application Firewall lacks some of the more specified and structured features offered by solutions like Tenable."
"There's potential for improvement in the platform's CMS integration."
"The usability of the interface could be improved."
"I would suggest that someone implementing this product is knowledgeable in the IT field, and with the network needs. It is complex."
"We get false positives about phishing emails."
"This product could easily progress to be among the industry leaders. I think they need to improve enterprise level automation. It integrates with a small number of vulnerability scanners, so report results should be imported manually; same for SIEM integration."
"For the first-time user, it is difficult to understand so the user-interface needs to be improved."
"Scalability can be an issue."
"The solution should provide more security for certificate-based services so that we can implement more security on that."
"Microsoft needs to work on their documentation."
"The solution can sometimes feel a little cumbersome unless you're a professional infrastructure person."
"There is room for improvement in the pricing model."
"Application Gateway’s limitation is that the private and the public endpoint cannot use the same port."
"The solution is easy to use overall, but the dashboard could be updated with a better layout and graphical design so that we can see the data a bit easier. Microsoft could also add more documentation. The documentation Microsoft provides doesn't tell us about resource requirements. We found that the instances we had weren't sufficient to support the firewall, so we had to increase them."
 

Pricing and Cost Advice

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The price is reasonable."
"A free version of the solution is available."
"We are using the free tier of the solution."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"There are no additional costs beyond the standard licensing fees."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"Cost is a bit on the higher side. Big companies can afford it."
"While I would have to check on the price of the solution, I feel it to be okay and it matches the market price."
"The product pricing was competitive for the value it offers regarding security features."
"The price of this solution is okay."
"The pricing is reasonable."
"The product is expensive."
"Barracuda costs us $8,000 per year. Barracuda costs $20,000 for a full subscription, when you try to protect multi-site infrastructure, in different geographical zones and for different data centers. If you have only one site, Barracuda will be cheaper."
"The pricing is less compared to other web applications."
"The tool's pricing model is pay-as-you-go."
"Microsoft Azure Application Gateway is expensive."
"Microsoft Azure Application Gateway has less price than other application gateway solutions."
"I would rate the pricing a three out of ten, with ten being cheap and one being expensive."
"Every solution comes with a license and cost. Microsoft provides the license and the total cost is for the maintenance every year."
"Between v1 and v2, there is a lot of change in the pricing. It is very costly compared to AWS."
"I rate the price of Microsoft Azure Application Gateway an eight out of ten."
"The price of the solution can be reduced a bit."
