OPERATIONS

Downtime cost estimator

For planning only. Enter your own assumptions; this is not a predictive model.

Illustrative total interruption impact—Labor cost + revenue impact; may overstate losses when the same activity is counted twice.
ACCOUNT HYGIENE

Passphrase length planner

Never enter a real password here. This is a theoretical search-space comparison, not an estimate of actual resistance to attacks.

Theoretical entropy, only if uniformly random—Real human-chosen passwords have less entropy. Use unique passphrases, a password manager, and MFA.

Where to go after the estimate

For account defenses, consult CISA guidance on passwords. For incident preparedness, see the CISA incident response planning guide.
