Polish detector coverage built around PESEL-led workflows
FastPII helps regulated organisations handling Polish data protect AI traffic with six detectors tuned to the structures found in customer support, onboarding, and internal casework. The Polish pack brings PESEL, business identifiers, and surrounding location fields into one security layer before the request reaches a model.
Polish pack summary
The Polish pack is useful whenever PESEL, business identifiers, and address data may appear together in the same AI-bound prompt, queue item, or case summary.
Six detectors for Polish citizen, business, and address records
The detector set covers the structured identifiers that matter most in Polish workflows, plus the location fields that often accompany them in free text.
PESEL
NIP
REGON
Postal code
Address
Phone
Mod-10-aware PESEL handling with Article 9-sensitive flagging
Structured validation matters most when identifiers drive automated masking, escalation, or audit decisions in front of AI systems.
Mod-10 for PESEL
FastPII can use Mod-10 logic when reviewing PESEL values, helping teams distinguish likely genuine identifiers from lookalike strings before protection or policy decisions are applied.
GDPR Article 9 flagging
PESEL encodes biological sex. FastPII can flag that fact for workflows that require stricter review, tighter masking, or escalation before the request is forwarded to an AI provider.
from fastpii import FastPII
client = FastPII()
result = client.protect(
"Proszę sprawdzić zgłoszenie klienta. PESEL 90010112345, NIP 5250001009 i adres Warszawa, ul. Marszałkowska 1.",
mode="redact",
)One policy layer for mixed Polish traffic
In practice, AI requests rarely contain PESEL alone. They usually arrive with names, addresses, business identifiers, or phone numbers. FastPII lets that whole bundle move through one detection, protection, governance, and audit workflow.
Add Polish identifier depth before requests move to the model layer
Use the Polish pack when PESEL-led workflows need checksum-aware review and protection tied directly to policy and audit outcomes.
