Where Zero Trust actually starts
Zero Trust isn't a product you buy. It starts with three unglamorous pieces of groundwork most organizations already half-have.
Sample article to show the layout. Replace it with your own writing.
Zero Trust is often sold as a platform. In practice it starts with groundwork that has nothing to do with a new purchase.
1. Know what you're protecting
You can't write access rules for systems you haven't listed. An accurate inventory of applications, data, and who owns them comes first.
2. Identity before network
Strong authentication and clean group membership do more than any new segment. Start with MFA on remote access and admin accounts, then remove stale accounts.
3. Small segments, explicit rules
A VLAN is not a security boundary on its own. Rules between segments should allow only what a service actually needs, and everything else should be logged.
What to measure
Track three numbers over time: admin accounts without MFA, stale accounts, and flows between segments with no matching rule. When they go down, you're making progress.
