F5 BIG-IP Local Traffic Manager and NetScaler are competitors in the application delivery controller market. F5 BIG-IP appears to have the upper hand due to its extensive customization and integration capabilities alongside its hardware performance, making it preferable for complex environments.
Features: F5 BIG-IP Local Traffic Manager stands out with advanced functionalities like iRules, iControl, and iApps, ensuring high customization for complex applications and impressive hardware performance for load balancing. In comparison, NetScaler is valued for its flexible deployment models, strong SSL offload capabilities, and detailed application reporting.
Room for Improvement: Users of F5 BIG-IP note the high cost and complicated configurations, requesting more straightforward licensing and better support for low-end platforms. NetScaler, while offering cost-effective scalability, faces criticism for its pricing and lack of flexibility in advanced customizations, although its underlying architecture is well-regarded.
Ease of Deployment and Customer Service: F5 BIG-IP provides robust support with a comprehensive community network, but its complex configuration often requires skilled partners. NetScaler is noted for its ease of use in deploying network architectures, though its customer service occasionally lacks the quick expertise available with F5.
Pricing and ROI: F5 BIG-IP is considered expensive, but its feature set justifies the cost for large enterprises, delivering significant ROI by enhancing security and performance. NetScaler, though cheaper than F5, faces criticism for pricing, with a need for competitive pricing to better align with its ROI and feature value.
The major return on investment is the security of our data.
I would rate the technical support of F5 BIG-IP Local Traffic Manager (LTM) nine out of ten.
Overall, my experience with F5 is very good compared to Radware.
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.
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.
