Clean Data Into Your Existing Stack
Built for Contact Centers Operating at Scale
Calls where customers read credit card numbers digit by digit. Years of archived transcripts that compliance never cleared for AI training. Hundreds of thousands of interactions daily that need protection before storage.

Years of Call Data. No Way to Use It.
A global contact center provider wanted to build AI-driven call summaries to improve performance and customer satisfaction, but years of unstructured Japanese call transcripts contained customer PII that blocked safe storage and analysis. Manual and Python-based redaction tools lacked the accuracy and scalability the volume required.
Limina Unlocked the Archive
Limina de-identified years of accumulated Japanese call data with custom rules for contact center language, catching PII in natural conversational speech where standard tools failed. Container deployment kept all data in-house. With the archive clean, the contact center now applies real-time de-identification prior to storage on every new call, turning compliance into a foundation for AI development rather than a barrier to it.
Frequently Asked Questions
What customer data should contact centers protect?
What customer data should contact centers protect?
Payment information—credit cards, CVVs, bank accounts—for PCI DSS compliance. Healthcare details—diagnoses, medications, medical record numbers—for HIPAA compliance in healthcare support centers. Account numbers, SSNs, addresses, and personal identifiers that create privacy risk when stored in CRM systems and quality management platforms. Beyond standard identifiers, Limina catches partial information like "card ending in 4532" and conversational fragments where customers share sensitive details across multiple sentences.
How does call transcript redaction affect PCI DSS scope?
How does call transcript redaction affect PCI DSS scope?
Transcripts containing credit card numbers bring your call analytics platform, CRM, and data warehouse into PCI scope with extensive security requirements. Redacted transcripts containing no payment data fall outside scope entirely—you store calls for QA, fraud pattern analysis, and agent training without PCI audit obligations applying to those downstream systems. This reduces compliance costs and simplifies security architecture for every system that only needs call content, not payment data.
How does Limina handle payment data the way customers actually say it?
How does Limina handle payment data the way customers actually say it?
Customers don't read card numbers in clean sequences. "My card is 4-5-3-2, wait, sorry, 4-5-3-3" gets detected. "The last four digits are 9-0-1-0" triggers redaction. Numbers split across sentences, corrected mid-reading, or referenced as "card ending in 4532" are all caught. Limina handles real-world speech patterns rather than only catching perfectly formatted card numbers read in sequence.
Can we still do quality assurance on redacted conversations?
Can we still do quality assurance on redacted conversations?
Yes. Redacted conversations preserve everything QA teams need except customer identities and payment details. Agent tone, empathy, problem-solving approach, script compliance, resolution effectiveness, and customer sentiment all remain analyzable. Format-preserving pseudonymization lets you track the same customer across multiple interactions without storing their real name. QA teams evaluate agent performance without needing access to sensitive customer data.
Does our data leave our environment?
Does our data leave our environment?
No. Limina deploys as a container in your on-premises environment or VPC. All processing happens inside your existing security perimeter—no third-party cloud processing, no external transmission. This matters especially for contact centers: call transcripts, chat logs, and customer communications never flow to external services before they're protected.
How does Limina handle multilingual contact center operations?
How does Limina handle multilingual contact center operations?
Limina works across 52 languages with region-specific detection for financial and personal identifiers across North America, Europe, Asia, and Latin America. Canadian SINs, UK NHS numbers, European IBANs, and Japanese personal identifiers are all detected alongside standard PCI from a single deployment. The system handles code-switching when agents and customers mix languages mid-conversation—common in multilingual contact centers and global support operations.
