F5 BIG-IP Local Traffic Manager (LTM) and NetScaler compete in the load balancing and application delivery category, with F5 having the upper hand due to its versatile integration and feature-rich offerings.
Features: F5 BIG-IP LTM offers iRules for scripting, iControl for management, and iApps for application templates, allowing flexible integration and comprehensive application environment support. It also includes intrusion prevention and a web application firewall, providing robust security. NetScaler provides strong load balancing and application delivery capabilities, including SSL offload and global server load balancing, with notable integration within Citrix environments that enhance user experience.
Room for Improvement: F5 BIG-IP LTM could be improved by reducing its initial cost and increasing the granularity of permissions. Users also desire better firmware quality and enhanced sync processes. NetScaler could improve by offering more stable operations, clearer documentation, and simplified configurations, as well as enhancing support responsiveness.
Ease of Deployment and Customer Service: F5 BIG-IP LTM is primarily deployed on-premises and is noted to be complex but supported by a strong community. However, some users report slower response times from support. NetScaler supports both on-premises and cloud deployments and has praised customer service, yet it faces challenges in initial deployments, with a desire for a smoother experience.
Pricing and ROI: F5 BIG-IP LTM is considered expensive, particularly for additional features, though users find the investment worthwhile due to its comprehensive capabilities. NetScaler's pricing is similarly high, yet it is seen as valuable, offering robust features that justify the cost. Smaller companies see pricing as a barrier, but those using NetScaler report satisfaction with its performance and capabilities.
The major return on investment is the security of our data.
Customer support is quite good but could be faster.
Overall, my experience with F5 is very good compared to Radware.
I would rate the technical support of F5 BIG-IP Local Traffic Manager (LTM) nine out of ten.
I expect faster resolutions when providing contact numbers while raising cases, as other companies typically do.
The pricing of F5 BIG-IP Local Traffic Manager (LTM) is on the higher side compared to competitors, but it is worth it.
The product is costly.
The impact of SSL offloading on reducing server load and latency is very much positive because whatever traffic we receive, we encrypt at our F5 BIG-IP Local Traffic Manager (LTM) level, which has definitely reduced the additional load and SSL decryption load on the servers, so it has very much helped us and it is very smooth; it will not take much time and will not impact our regular traffic.
R-series has better CPU and memory, leading to higher throughput with minimal downtime, making it a significant improvement over the I-series.
One of the most beneficial features of F5 BIG-IP Local Traffic Manager (LTM) is its ability to identify compromised traffic and its capabilities in authentication.

F5 BIG-IP LTM optimizes the speed and reliability of your apps via both network and application layers. Using real-time protocol and traffic management decisions based on app and server and connection management conditions, and TCP and content offloading, BIG-IP LTM dramatically improves application and infrastructure responsiveness. BIG-IP LTM's architecture includes protocol awareness to control traffic for the most important applications. BIG-IP LTM tracks the dynamic performance levels of servers and delivers SSL performance and visibility for inbound and outbound traffic, to protect the user experience by encrypting everything from the client to the server.
BIG-IP LTM provides enterprise-class Application Delivery Controller (ADC). You get granular layer 7 control, SSL offloading and acceleration capabilities, and advanced scaling technologies that deliver performance and reliability on-demand. The highly optimized TCP/IP stack combines TCP/IP techniques and improvements in the latest RFCs with extensions to minimize the effect of congestion and packet loss and recovery. Independent testing tools and customer experiences show LTM's TCP stack delivers up to a 2x performance gain for users and a 4x increase in bandwidth efficiency.
