Centralized security has protected APIs and optimized multi‑cloud traffic management
F5 Distributed Cloud Services has been used for two years for DDoS protection, and there is a particular feature called API protection. Within API protection, there is malicious user mitigation, which is one particular technology that has been implemented. This is a kind of advanced bot attack prevention. Malicious user mitigation is an AI/ML-based technology that was introduced by the F5 team, and this particular MUG protects rate limiting. If some users are having anomaly detection or someone is trying to do a bot attack, it will create a CAPTCHA challenge for that particular user alone and not for all users. For example, if someone is trying to act as a rogue, it will create a CAPTCHA challenge in the backend system on that particular system, so they cannot try again and again at the same time. It is for a concurrent session, and it will give the CAPTCHA challenge. This MUG, malicious user mitigation, prevents bot attacks. F5 Distributed Cloud Services includes the real-time intelligence feature, which helps with threat response strategies from a threat intelligence perspective. For example, if there are geo-restrictions or geo-based restrictions, sometimes people may come in through proxy-based servers, and it will prevent that. The load balancing feature optimizes application performance. Observability is the basic piece where F5 got introduced. This observability piece provides end-to-end visibility on the application performance. It gives complete end-to-end visibility across network latency and application performance issues. Sometimes when it is getting more than 200 pages, it throws errors such as 300, 400, or whatever has been configured, including 500 errors. F5 Distributed Cloud Services has helped improve traffic management efficiency. Most applications are hosted in the Check Point and F5 firewall, F5 web application firewall, where applications and traffic management can be accessed in a single dashboard. Automated threat detection is a basic feature of F5 Distributed Cloud Services meant for that purpose. There are two scenarios with automated threat detection, which is provided by F5. It is a completely machine learning solution that came from the bot defense, and it automatically protects against sophisticated attacks.

Load balancing and secure access have supported complex migrations and automation at scale
NetScaler has positively impacted my organization because I work for a system integrator and deploy it for customers. Many customers are really happy with NetScaler, except for the pricing, as Citrix has changed a lot of their pricing in the last two or three years when they transitioned to Cloud Software Group. However, despite that, I know customers are really satisfied with the technical capabilities that NetScaler provides. While I do not have specific outcomes or metrics from my customers, I think using Core Logic has made it much easier for the big municipality I mentioned to implement NetScaler as a total solution, thus speeding up their automation. There are likely many benefits, but I lack benchmarks or timing figures to quantify that.

Quotes from Members

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

Pros

"Technical support from F5 is good compared to Cisco and HP."
"F5 is known for being the best load balancer in the market. Customers with an existing module can easily adopt additional modules without investing in new hardware."
"F5 Distributed Cloud Services is the market leader in load balancers and manages traffic really well."
"The main benefit is Web App Security, offering a complete security package from DDoS to web application firewall, API protection, and bot mitigation."
"Elastic environments are the most valuable features because I can pull these apps and migrate the on-premises environment to the Distributed Cloud environment, and this capability is very strong and the security regarding the apps is really very powerful."
"F5 Distributed Cloud Services provides a single unified console for security operations, network operations, and DevOps across all environments."
"In a multi-cloud or distributed cloud, there are many protection possibilities from data to web application or API protection, including bot mitigation."
"I appreciate the UI of F5 Distributed Cloud Services and the backend cost, alongside the actual value proposition that they provide with the load balancer, which is excellent."
"We use the product for load balancing and as a reverse proxy solution."
"It is a stable solution. It crashed only once, four years ago...There is a return on investment using the solution."
"Citrix Netscaler makes it easy to provide services to end users, offering better visibility into user sessions compared to VMware. However, instability in network or machine can cause headaches as it's hard to pinpoint issues. SSL offload feature enhances security posture by providing secure connectivity between end users and backend systems. We use additional Azure remote security solutions for comprehensive protection."
"Manageability and visibility are good."
"The most valuable feature for us is the application firewalling in Citrix NetScaler, ensuring only valid traffic enters our environment."
"Citrix is a complete solution for those looking for an all-in-one; it's all there, the NetScaler gateway, remote access, internet access, optimization, load balancing, Citrix desktop publishing, and VDAs, so you can create a complete solution with Citrix."
"Load Balancing and SSL offloading are key features."
"The most valuable feature is the capability of performing load balancing in a virtual environment."
 

Cons

"The worst experience is that with so many solutions available, it is very complicated to know all of the solution modules, and the offers from F5 Distributed Cloud Services are vast."
"For small players, it is completely not worth it."
"The pricing could be adjusted to better meet the needs of typical customers in regions like Poland, where the product is considered too expensive."
"One area where F5 Distributed Cloud Services can be improved is in API security, which can be enhanced."
"The main issue is integration with other parts or products of F5, like on-premise WAF. There are some problems, mainly from the perspective of implementation and customer expectations, which sometimes differ from reality."
"Last year there was a downtime of 30 minutes across the cloud distributed console, and that was the only impact observed."
"The solution is a bit more expensive than some of the available solutions in this region. One solution in particular that I noticed was cheaper was Kemp."
"There is room for improvement regarding the pricing policy for Citrix offices."
"I will try to migrate all the tools to the cloud because there is more lab and more VPN scalability available in the cloud. It is not available on-premises."
"I think the interface could be better. I think some customers struggle with that."
"Quality assurance could improve by ironing out security vulnerabilities before releasing upgrades."
"The technical support could be better. Whenever I contacted support, I rarely got the solution that we needed. And most of the time, I finished fixing the problem by looking on the internet or by finding documents about the problem on Google."
"It is difficult to customize. It is more difficult to customize than F5, for example."
"We would like the licensing model for this product to be improved, as it isn't currently very transparent. There isn't a standard package available, and each extra feature creates an additional cost."
 

Pricing and Cost Advice

Information not available
"The client pays for the Citrix NetScaler license annually."
"We get value for money. Its price is fair. I don't think it is overpriced."
"Citrix ADC could improve the price and make it less expensive, other competitors have a better prices. This would allow Citrix ADC to keep dominating the market."
"It is true that it is a bit pricey compared to newer technologies coming to the market. For example, A10 is a load balancer that does everything that Citrix can and it does a lot more than what NetScaler does when it comes to the security space, and their prices are so cheap. Every box comes with its own license and support built into it. When you compare that with NetScaler, you have to buy licenses separately, you have to buy a support agreement that is going to be separate. A small NetScaler, even if it is a VPX which is a virtual server, could cost you close to $150,000 to $200,000 dollars. So the pricing is really high."
"Licensing is adequate. I wanted to have a more prominent license, but until I do they don't give enough support. The additional cost would be too much."
"The tool is cheap."
"We have all the features and functions of Citrix because we have a premium license."
"After deployment, Citrix Netscaler shifted to a subscription-based license scheme for support, which is slightly more expensive."
