Load Balancer Privacy By Default is not a feature you bolt on; it’s a baseline. When every request crossing your network hides sensitive metadata, risk drops fast. The load balancer becomes the gate, not a leak point.
Most deployments still ship with verbose logging and traffic inspection turned on. This default exposes client IPs, User-Agent strings, and session identifiers. Each field can be exploited or combined to profile users. Privacy by default flips this. Discard or anonymize at the edge. Retain only what is required for operational health: status codes, timestamps, and aggregate metrics.
A privacy-focused load balancer configuration starts with endpoint sanitization. Strip query parameters from logs. Remove referrer headers before they hit downstream services. Replace IP addresses with irreversible hashes or regional groupings. Disable diagnostic trace modes in production. Ensure SSL termination enforces modern cipher suites so intermediaries cannot read payloads.
