Rate Limit to Protect the ServerDetect and Block Bots and Bad ActorsCreate and Enforce Dynamic Signatures
Analyze Application Stress and Continually Tune Mitigations.
Start of AttackIdentify AttackersAdvanced Attacks
Persistent Attacks
Multiple Layers of Protection
Even basic attacks can take an unprotected server down quickly.
Persistent attackers will adjust tools, targets, sources and attack volume to defeat static DOS defenses.
The F5 approach protects the server from the first moment of the attack and then analyzes the attack tools, sources and patterns to refine mitigations.
These sophisticated protections maximize application availability while minimizing false positives.
