Why it shows up like this
Unreviewed registry note: A line item formatted as DUO SECURITY* CISCO on your bank or credit card statement indicates a software subscription charge from Cisco Systems, Inc. / Duo. Duo Security is an enterprise cybersecurity business that delivers two-factor authentication and single sign-on access tools. When this descriptor appears on your statement, it reflects monthly or annual billing for the Duo Security Multi-Factor Authentication Platform.
Unreviewed registry note: Duo Security bills organizations primarily on a per-user licensing model. Unexpected charges often happen when an IT department upgrades an organization beyond the free 10-user tier to paid editions like Duo MFA or Duo Access. Charges can also fluctuate when new staff members are provisioned into company identity systems, triggering automatic seat additions. Similar to other enterprise access management tools like Okta or Auth0, subscriptions renew automatically on a recurring monthly or annual schedule using the payment card registered in the administrator console.
