- RADIUS network devices are free
- Switches, access points, controllers, and every other RADIUS client are unlimited on both plans in their RADIUS role: the authentications they carry are never a device charge. You never pay for plumbing.
- Users vs devices
- A user is a person who authenticates, over 802.1X, TACACS+, or a certificate. A device is a MAC-authenticated endpoint or a machine that signs in on its own.
- One identity, one charge
- The same person on a laptop, a phone, and a switch console counts once when they authenticate as the same normalized identity within the month. For RADIUS the identity is the login's email address when it carries one, otherwise the username; for TACACS+ it is always the username; both are lowercased. Two different normalized identities are counted separately.
- Certificate authentication
- When a user certificate and a machine certificate authenticate together, only the user is billed. The machine is not counted again.
- TACACS+ managed devices
- Network equipment that administrators sign into through TACACS+ counts as a device at $1 per month. RADIUS network devices remain free.
- Metered from logs
- Counts come from accepted authentications in your logs, not from a directory, so you pay only for identities that actually connect.
- No proration
- The Business minimum and the Enterprise base fee are charged in full for every month in which your account is still active when that month's charge is calculated, shortly after the month ends. There is no proration for a partial first or last month, or for a month in which you change plans. The $50 paid at signup is that first Business month.
- Plan changes
- Switching on an Enterprise feature moves your account to Enterprise as soon as an account owner accepts. Any month in which your account is on Enterprise at any point is billed as Enterprise, in full. Moving to Business takes effect at the end of the month. Virtual appliances and SAML sign-in must be removed first; other Enterprise features stop, and their settings are kept. Business pricing applies from the following month.
