Use the hardening tool of the Security Center to see your hardening compliance score, compare it with previous scores, and change the settings to improve your compliance score and security posture.

The Hardening settings specify recommended values for the security related properties and plugins in the ServiceNow AI Platform. The hardening tool calculates the hardening setting compliance score as a percentage. This number indicates how compliant your instance is with the Security Center hardening settings.

The formula for calculating the hardening compliance score:

• Each hardening setting has a risk score between 0-10.
• The score equals the sum of all the compliant risk scores divided by the sum of all risk scores.

For example, if the sum of all the compliant risk scores is 25.4, and the total for all risk scores is 34.9, then the compliance score will be (25.4 /34.9) × 100 which equals 72.7. This decimal gets rounded up to the nearest whole number and will therefore be equal to 73.

This calculation is automatically performed on the first of the month, or after an installation or re-installation of ServiceNow Security Center.
