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.
DEMİRHAN ÇAVUŞOĞLU - PeerSpot reviewer
A tool for centralized management including inventory and sales tracking
Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.

Quotes from Members

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

Pros

"It is a fast and secure DNS."
"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 a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"It is a fast and secure DNS."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"It's very simple and predictable, because Barracuda provides a vision of the current state of your application. It gives you an understanding of what is happening on your site and any attempts against you at your source. This is the main value that Web Application Firewall provides our company. These aspects are also the main reason for this documentation process."
"The solution's most valuable feature is that it actually protects our website, and it provides all the required security functions."
"The most valuable features of Barracuda Web Application Firewall include advanced bot protection, DDoS protection, and addressing the top ten vulnerabilities."
"Has a good dashboard."
"I find the solution very stable."
"We only need one subscription to be protected against both active DDoS and offline DDoS attacks."
"One of the strongest points is its robust issue discovery capabilities. Barracuda invests significant efforts in identifying and resolving issues. They have multiple products that work in tandem to perform these checks, which is beneficial because it automates security updates. This is the primary reason I recommend it to my customers."
"It significantly improved our overall web security posture, addressing intrusions and enhancing control over web URLs in our environment."
"Content Switching provides flexibility for routing traffic as desired to designated real servers. It also provides good geo capabilities through its GSLB feature."
"I like the solution's simplicity compared to Citrix's on-prem solutions."
"We have good customer support."
"The load balancing and VPN features are most valuable. AAA authentication is also valuable."
"The analytics are a great feature."
"An essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently."
"Enables a Web service that offers persistent client-server connections, IP restriction, URL rewrite (such as remove "/assets/" path from client-side URL path), and cache for CSS or JS files... You can easily use the GUI to set up all these requirements on the same network device within 20-30 minutes. (If you do the same steps on CLI, it might take less time.)"
"The most valuable feature of Citrix NetScaler was the seamless integration. Additionally, the UI is good."
 

Cons

"DNS Management."
"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."
"The documentation could improve for Cloudflare DNS."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"The solution could be more user-friendly."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"We encountered a few glitches while implementing API security features into the product."
"The platform's pricing needs improvement."
"Barracuda Web Application Firewall's load balancing feature could be improved."
"There are some vulnerabilities that are reported across the tools offered by Barracuda for some devices, which need to be taken care of from an improvement perspective."
"If you know nothing about networks, then you can't set it up."
"An area for improvement in Barracuda Web Application Firewall is attack identification. Other banks identified attacks and tracked logs that the solution wasn't able to identify because of its ready-made rules pre-deployed by the vendor. My organization raised this issue with the technical support team. Another area to improve in Barracuda Web Application Firewall is its service desk. The team resorted to stonewalling because they couldn't accept that a feature was missing in the solution, and it was only after a lot of drilling down that the service desk team accepted that, and would be adding that feature in the future. My organization had to submit a report to the Reserve Bank of India with information on the logs identified and the attacks that happened, and that there was a failure on the part of the Barracuda Web Application Firewall. The Reserve Bank of India conducts a tri-monthly cyber risk audit in all Indian banks. Even smaller banks identified and caught attacks that my organization wasn't able to do, so I was looking into other solutions that competitor banks could be using because Barracuda Web Application Firewall failed to identify some of the attacks."
"Barracuda Web Application Firewall’s scalability needs improvement."
"The solution needs to leverage some additional features to a broader scale of software-defined networks."
"Technical support could be improved."
"I feel that Citrix NetScaler's customer support needs to improve."
"I think there is always room for improvement in this type of solutions. For example, I think the GUI should be easy to understand."
"Does not include security. A web application firewall would be a nice addition."
"Some of our customers have questioned the security of this solution lately, wondering whether it is safe or not, so enhancements in this respect would be good."
"Citrix is more expensive than Horizon."
"I would like to see multifactor authentication added to this solution to improve the security."
"The SLB could be better, and they should improve it."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"The cost primarily depends on the size of the organization."
"That is one of the great features. I was able to access the majority of the features and services for free."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"We don't have any issues with the price."
"We are using the free version."
"The price of the solution is expensive."
"The price is reasonable, more so than other products."
"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 pricing is reasonable."
"In my opinion, the product is fairly priced."
"For small companies, the price is very expensive because the WAF is an enterprise-level application, not intended for smaller businesses. In my opinion, the price is right for enterprise-level use."
"The product is expensive."
"While I would have to check on the price of the solution, I feel it to be okay and it matches the market price."
"Regarding pricing, while it's expensive, I can't comment on the exact ROI without a budget analysis. However, in terms of service quality, it's worth the price."
"For partners, NetScaler is not as expensive price-wise versus F5."
"Our licensing fees including technical support are approximately $3,500 USD."
"It is very pricey, but we get it. If you need the best, money shouldn't be a problem."
"It's not for startups or SOHO."
"The solution is expensive compared to one of its competitors."
"For the specific use case that my customers primarily engage with, I would give the pricing a rating of seven out of ten."
"The tool is cheap."
