Key Features and Functionality
Application Delivery and Load Balancing
- High-Performance Load Balancing: F5’s BIG-IP Local Traffic Manager (LTM) efficiently distributes traffic across multiple servers to ensure optimal application performance and availability. This includes layer 4-7 load balancing, supporting various protocols and application-aware routing.
- Global Server Load Balancing (GSLB): This feature delivers a consistent user experience globally by managing geographically distributed applications.
Application Security
- Web Application Firewall (WAF): The BIG-IP Application Security Manager (ASM) and Advanced Web Application Firewall (AWAF) protect web applications from attacks, including DDoS, web scraping, and credential stuffing. These modules offer PCI-compliant security, integrated XML firewalls, and continuous attack signature updates.
- Bot Management: F5’s solutions use advanced machine learning to identify and block malicious bots, ensuring the integrity of applications and infrastructure.
DNS Security
- DNS Services: F5’s DNS module, formerly known as the Global Traffic Manager (GTM), provides intelligent DNS resolution with support for DNSSEC. It can resolve each individual URL differently based on various metrics such as health and performance monitors, GeoIP, and EDNS0.
- DNS DDoS Attack Prevention: F5’s solutions help mitigate DDoS attacks and prevent DNS hijacking, protecting valuable domain names.
Network Functions Virtualization (NFV)
- F5 helps service providers virtualize their network functions, such as firewalls and load balancers, to improve agility and efficiency. Their service delivery platform supports the building and deployment of virtual network functions.
Cloud Services
