Google Workspace and Microsoft 365 settings that actually matter.
Turn on early
Enforce MFA, limit external sharing defaults, reduce risky apps, alert on suspicious login if available.
Admin hygiene
Dedicated admin account with MFA; break-glass procedure.
Offboarding
Suspend, transfer Drive ownership, check forwarding.

Founders often underestimate how quickly small gaps become expensive incidents. The gap is rarely a missing enterprise tool; it is missing ownership, missing MFA, or a shared password that outlived a contractor. Treat every login that can reset another login as critical infrastructure.
Write down where customer data lives—even if the list fits on one page. Email, CRM, billing, file storage, and chat backups are the usual suspects. When something goes wrong, that map is the difference between calm containment and improvisation.
Security habits beat security theater. A quarterly one-hour review of admin accounts, external shares, and backup restores will outperform a unread 40-page policy. Keep the ritual short so the team actually does it.
When you evaluate change, ask a simple question: does this reduce the chance that a single phished inbox can take over Google Workspace and Microsoft 365 settings that actually matter? If the answer is no, keep iterating. Prefer boring controls that survive busy weeks.
Document break-glass access. If the only person who can unlock the company vault is offline, you do not have resilience—you have a single point of failure wearing sneakers.
Practical checkpoints you can run this month
- Confirm MFA on email, banking, cloud admin, and code hosting
- Rotate any password that was ever shared in chat
- Test restoring one critical folder from backup
- Remove dormant accounts and unused OAuth apps
- Assign an owner for domain, DNS, and hosting logins
None of this replaces a professional audit when contracts or regulated data require one. It does create a foundation that prevents the most common early-stage failures while you build the product.
Revisit your checklist after each hire, each new SaaS tool, and each scare. Security is a living operating system for the company, not a certificate on the wall.
