Capital One builds a custom tokenization engine that preserves format, detokenizes on demand, and serves roughly 15k TPS / 160B ops per month while keeping high availability; teams adopt it in under a month (≈ one developer-month). Detection uses a homegrown scanner that scans S3 buckets and data lake exports (databases are dumped to S3), costs about $50k per PB, yields ~30% SSN false positives, and forces SLAs (10‑day triage, 120‑day remediation); free‑text, images and encrypted files remain the hardest gaps.
