BIG-IP software modules include BIG-IP ASM, BIG-IP LTM, BIG-IP DNS, BIG-IP APM and BIG-IP AFM among others.

Below is a high-level overview of the well-known BIG-IP software modules.

📌 BIG-IP Access Policy Manager

Secures, simplifies, and protects user access to apps and data. It controls access to resources by identifying, authenticating and authorizing the users.

📌 BIG-IP Advanced Firewall Manager

F5 BIG-IP AFM is a high-performance, stateful, full-proxy network firewall designed to protect data centers against incoming threats that enter the network on the most widely deployed protocols including HTTP/S, SMTP, DNS, and FTP.

📌 BIG-IP Advanced WAF/ASM

Provides protection against OWASP Top 10 Web Application Security risks. It proactively detects and mitigates bots, secures credentials and sensitive data, and defends against application DoS. Protects apps with behavioral analytics, bot defense, and app-layer encryption with dedicated Layer 7 protection.

📌 BIG-IP DNS

BIG-IP DNS distributes DNS and user application requests based on business policies, data center and network conditions, user location, and application performance. Provides hyperscale and security during high query volumes and DNS DDoS attacks.

📌 BIG-IP Local Traffic Manager

Manages network traffic so applications are always fast, available, and secure. The most widely deployed and most commonly used F5 BIG-IP module. It can be considered as the default module. It is much more than a load balancer!

BIG-IP LTM provides you the power to scale, automate and customize your applications and services faster and reliably.
