Redaction
Redaction is removing or masking sensitive information (PII, secrets, credentials) from text, logs, documents, or outputs.
AI systems create rich telemetry. Without strong redaction, you risk leaks through logs, traces, caches, and debug UIs.
Explanation
Redaction can be rule-based, ML-based, or hybrid, and often replaces sensitive values with stable tokens to preserve analytics utility.

Why does Redaction matter for marketing teams in 2026?
AI systems create rich telemetry. Without strong redaction, you risk leaks through logs, traces, caches, and debug UIs. Companies that introduce Redaction in a structured way typically report 20–40% efficiency gains within the first 6 months.
How do I introduce Redaction in my company?
