Backup recovery time calculator (RTO / RPO)
Free backup recovery time calculator. Enter data volume and restore throughput to estimate recovery time, compare it against your RTO, and understand your RPO from backup frequency.
-
Brute-force & rate-limit calculator
Free brute-force rate-limit calculator. Enter login attempts per minute and lockout settings to see how long it would take to crack common credential types — from 4-digit PINs to 8-character passwords.
-
Data breach cost estimator
Estimate the cost of a data breach based on records exposed, data type, industry, and jurisdiction. Covers regulatory fines, notification, legal, remediation, and business impact — with low and high range outputs.
-
Downtime cost calculator
Free downtime cost calculator. Enter your hourly revenue, outage duration, and how much of that revenue is actually lost versus delayed to see the real cost of an incident.
-
Password breach checker
Check if a password has appeared in known data breaches using the HaveIBeenPwned database. Your password is hashed in the browser — only a 5-character prefix of the hash is ever sent over the network.
-
Password entropy & crack-time calculator
Free password entropy and crack-time calculator. Enter a password length and character set to see its entropy in bits and an estimated time to crack against different attacker speeds.
-
Password policy strength calculator
Free password policy strength calculator. Enter minimum length, character requirements, and rotation period — see the entropy it guarantees and estimated crack times across five attack speeds.
-
Secure passphrase generator
Free secure passphrase generator. Create memorable multi-word passphrases using cryptographically secure randomness — nothing is transmitted, everything runs in your browser.
-
TLS certificate expiry calculator
Free TLS/SSL certificate expiry calculator. Enter issue and expiry dates to see days remaining, renewal deadline, and health status — with a configurable renewal buffer.
