Microsoft 365 Security

Your identity is your

perimeter. Protect it.

If your organization uses Microsoft 365, your Entra ID (formerly Azure AD) is the front door to everything- email, files, apps, and data. These are the five steps Microsoft recommends to harden it. We’ve simplified each one so you can do it yourself- or hire us to do it for you.

Why this matters right now

  • 50 Million Password Attacks Daily

    Microsoft observes this across Entra ID tenants- most organizations are not using strong authentication.

  • Phishing is the #1 reported cybercrime

    Per FBI IC3 reports- credential phishing was used in the most damaging attacks of recent years.

  • MFA blocks 99.9% of account compromise

    The single most impactful thing you can do- and most organizations still haven’t fully deployed it.

The five Initiative Checklist

Harden your Microsoft 365 identity – step by step.

Based on Microsoft’s official security guidance for Entra ID. Each step includes what to do, how hard it is, and the option to bring us in.

Credential Hardening

Strengthen your credentials

Moderate Effort

Password-based attacks are still the most common way accounts get compromised. Spear phishing and password spray campaigns succeed because most organizations rely on passwords alone. These four actions close the most critical gaps.

Enable MFA for all users

Use Microsoft Entra Security Defaults (free) or Conditional Access (P1/P2) to require multi-factor authentication across your tenant. This single step blocks the vast majority of attacks.

Enable banned password protection

Turn on Microsoft Entra Password Protection to block commonly attacked passwords and custom terms. Traditional complexity rules don’t work — this does.

Remove password expiration policies

NIST and Microsoft research both confirm forced expiration makes security worse — users pick weaker, predictable passwords. Remove expiration and rely on breach detection instead.

Enable password hash sync

If you use hybrid identity (on-prem AD + cloud), enable password hash synchronization. This enables leaked credential detection and provides a cloud auth fallback if your on-prem environment is hit by ransomware.

Attack Surface Reduction

Reduce Your Attack Surface

Significant Effort

Every unnecessary access point is a potential entry for an attacker. This step is about closing off the doors you’re not using- legacy protocols, unrestricted admin access, and unchecked app permissions.

Block legacy authentication protocols

Apps using POP3, IMAP4, SMTP, or older authentication methods bypass MFA entirely. Identify legacy auth in your sign-in logs and block it via Conditional Access or Security Defaults.

Restrict access with Conditional Access

Define who can access what — and block everything else. Apply policies based on user group, device compliance, network location, and risk level. Verify explicitly; trust nothing by default.

Review and restrict admin roles

Apply least-privilege. Most admins don’t need Global Admin. Audit who has privileged roles, remove unnecessary assignments, and ensure admin accounts are cloud-only — not synced from on-prem.

Privileged Identity Management (PIM)

Require just-in-time activation for privileged roles. No permanent standing access. Admins activate the role when they need it, with MFA and approval, and it expires automatically. Requires Entra ID P2.

Restrict user consent for apps

Prevent users from granting third-party apps access to company data without admin review. Require admin consent for all OAuth apps — or at minimum, restrict consent to verified publishers only.

Move to passwordless authentication

Windows Hello for Business, Microsoft Authenticator app sign-in, or FIDO2 security keys eliminate password risk entirely. Passwordless is the long-term goal — start planning the migration now.

Automated Response

Automate Threat Response

Significant Effort | $ Requires P2 License

The time between when an account is compromised and when you respond determines the damage. Microsoft Entra ID Protection uses machine learning to detect risky behavior and can automatically respond – blocking access, requiring MFA, or forcing a password reset – before a human has to act.

Configure sign-in risk policies

Create Conditional Access policies that trigger on suspicious sign-in characteristics — unfamiliar location, anonymous IP, atypical travel. Require MFA for medium risk; block high-risk sign-ins.

Configure user risk policies

If Entra ID detects that a user’s credentials are likely compromised — leaked password, anomalous behavior — automatically require a secure password change with MFA before access is restored.

Integrate Microsoft Defender XDR

Connect Defender for Endpoint, Defender for Office 365, Defender for Identity, and Defender for Cloud Apps to feed signals into Identity Protection.

Set up monitoring and alerting

Route Entra ID logs to Microsoft Sentinel, Azure Monitor, or your SIEM. Establish alert rules for critical events. Make sure someone is reviewing risky sign-in and risky user reports daily.

Risk policy configuration requires Entra ID P2 and careful tuning to avoid alert fatigue and false positives.

Visibility and Monitoring

Use cloud intelligence

Moderate Effort

You can’t protect what you can’t see. Microsoft 365 generates enormous amounts of security-relevant data — sign-in logs, audit trails, risk detections — but most organizations never look at it. These steps turn on visibility and connect your data to actionable intelligence.

Monitor Entra ID audit and sign-in logs

Review sign-in and audit logs regularly. Look for unusual sign-in patterns, admin role changes, app consent grants, and sign-ins from unexpected locations or devices. Set a log retention policy.

Monitor Entra Connect Health (hybrid)

If you’re running hybrid identity with AD FS or Azure AD Connect, monitor the health of your synchronization infrastructure. Treat hybrid infrastructure like your most critical asset.

Review risky sign-ins and risky users daily

Entra ID Protection surfaces two key reports: risky sign-ins (is this really the legitimate user?) and risky users (accounts that show signs of compromise). Review both. Investigate and dismiss or remediate.

Audit app consent permissions

Review what OAuth permissions users have granted to third-party applications. Malicious apps can gain persistent access to mailboxes, files, and data through consent phishing. Revoke anything suspicious.

Setting up log export, SIEM integration, and building a regular security review cadence is something we can establish for you.

User Enablement

Enable end-user self-service

Low Effort

Security friction drives users toward workarounds. Give your team the tools to help themselves, and you reduce helpdesk burden while maintaining security. These are the self-service capabilities Microsoft provides in Entra ID that most organizations don’t fully deploy.

Enable self-service password reset (SSPR)

Let users reset their own passwords securely — without calling the helpdesk. Requires users to register backup authentication methods. Reduces helpdesk tickets and eliminates a social engineering attack vector.

Enable self-service group and app access

Let group owners manage their own groups. Let users request access to applications through a governed workflow rather than emailing IT. Entra Entitlement Management automates access lifecycle and expiration.

Implement access reviews

Schedule regular reviews of group memberships, application access, and privileged role assignments. Entra access reviews notify the right people and automatically remove access that isn’t reconfirmed.

Audit app consent permissions

Connect your HR system to Entra ID so accounts are created when employees are hired and disabled immediately when they leave. No manual offboarding gaps. No lingering access after someone’s last day.

SSPR registration campaigns, access review schedules, and HR-driven provisioning setup are straightforward engagements with positive payoff.
