5 Identity Controls Every Organization Should Implement
Most security incidents don’t start with a sophisticated attack. They start with a login that shouldn’t have worked. MFA is a critical baseline — but it’s not the finish line. Here are five high-impact identity controls you can implement in Microsoft 365 (often with licensing you already own) to reduce takeover risk without adding new tools or headcount.
Identity is the new perimeter
The old model assumed everyone worked inside the office and the firewall kept threats out. That model is gone. Today, users sign in from home, hotels, client sites, and personal devices. When an identity is compromised, the attacker looks exactly like an employee — and they can access email, files, and client data quietly for weeks.
5 identity controls to implement beyond MFA
These controls are practical, high-impact, and achievable for lean teams. Start with the highest-return items first, then layer in the rest. Small configuration changes compound quickly.
1) Conditional Access
Context-aware sign-in rules that evaluate risk signals in real time (location, device, user risk, client app).
Start here: block legacy authentication + require MFA for all admin roles.
2) Least Privilege
Reduce the blast radius. Admin access should be rare, time-bound, and tied to documented role requirements.
Start here: audit Global/Exchange/SharePoint Admin roles and remove anything without a current business reason.
3) Separate Admin Accounts
No single account should do everything. Daily email accounts shouldn’t also be Global Admin accounts.
Start here: create admin-only accounts (no mailbox) for anyone doing administrative work.
4) Reduce Legacy Authentication
Legacy auth bypasses modern controls. It’s a common target for password spray and account takeover attempts.
Start here: review Entra sign-in logs by “Client App” to identify dependencies before deprecating.
5) Monitor Risky Sign-ins
You don’t need a 24/7 SOC — you need cadence + a simple response routine for flagged sign-ins.
Start here: schedule a 15–20 minute review twice a week of Identity Protection alerts.
Quick win: Admin audit
Ask one question today: who has admin access in Microsoft 365 — and do they still need it?
This 30-minute check often reveals more identity risk than people expect.
Achievable—even for lean teams
A common objection to security hardening is bandwidth. IT teams are stretched, and security feels like “a project.” The reason these five controls are worth prioritizing: they’re measurable configuration improvements that can be phased in without adding new tools or headcount.
Your next step
Start with clarity. Before you can fix what’s wrong, you need to know what’s misconfigured, what’s disabled, and where your real exposure lies.

Harden with minimal interruption
Fortify delivers a structured, phased path to Microsoft security hardening that’s designed to stick in real-world environments.
Make it routine
Identity protection works best when it’s reviewed consistently: alerts, risky sign-ins, admin access, and policy drift.
Ready to harden identity without adding new tools?
Start with a baseline and a clear, prioritized plan. Then implement improvements in phases — aligned to Microsoft best practices and built for the realities of lean teams.

Is MFA still important?
Yes — MFA is a critical baseline. The issue is that attackers have adapted (phishing, legacy auth bypass, session theft). These additional controls reduce takeover risk significantly.
Do we need new tools to implement these controls?
Usually not. Many organizations already own these capabilities within Microsoft 365 licensing. The work is primarily configuration, verification, and creating a simple review routine.
What’s the fastest place to start?
Start with admin access: review who has Global/Exchange/SharePoint Admin roles and remove anything without a current documented business reason. Then implement Conditional Access basics (block legacy auth + require MFA for admins).
How often should we review risky sign-ins?
Twice a week is a strong starting cadence for most lean teams. A 15–20 minute review routine can materially reduce the time-to-detect suspicious activity.
How do we know what’s misconfigured or disabled today?
