Custom Client Identifiers: Smarter Client Tracking for Security Teams

Custom Client Identifiers: Smarter Client Tracking for Security Teams

Relying on IP addresses alone isn't enough to reliably track or distinguish clients—especially in modern, complex environments. That’s why we’ve introduced Custom Client Identifiers, giving your team the flexibility to define what a “client” really means based on your specific use case.

Whether it’s IP + User-Agent, IP + API Key, or Token + Product Identifier, you can now tailor client identification to suit your architecture and security goals.

Even better, Custom Client Identifiers can be pre-configured and reused as objects across multiple rules—so you don’t need to redefine the same logic every time. Set it once, use it everywhere.

With Custom Client Identifiers, you can:

• Log traffic more meaningfully
• Rate limit based on true client behavior
• Block malicious activity more accurately
• Detect attackers hiding behind shared IPs

Define clients on your terms—and take control of how your system sees and responds to them.
