Yes. On Professional plans you add your logo and firm name. On Firm plans you get full white-labeling including a custom domain (e.g., verify.yourfirm.com) so clients never see "BasilTax."
All SSNs and PII are redacted before any AI processing. Data is encrypted at rest and in transit. We never sell, share, or use client data for model training. See our security page.
