Security Center overview
The Security Center answers the two questions every Salesforce admin gets asked in an audit:
Your org's security score
Every analyzed org gets a security score — a single number summarizing how safely the org is configured, so you can track posture over time and compare orgs at a glance.
Analyzing user access
The Security Center is user-first: instead of burying you in abstract findings, it shows you people — who they are, what they can do, and why.
Access lookup: who can touch this?
The access lookup answers the reverse question: not "what can this user do?" but "who can do this?". It's the fastest way to answer audit requests like "list everyone who can read the SSN field" or "who can execute this Apex class?".
