The Top 10 Secure Score Actions That Deliver the Biggest Risk Reduction
For many organizations, especially manufacturers balancing IT, OT, and lean staffing, Microsoft Secure Score can feel like just another dashboard metric. But behind that percentage is one of the most powerful, data‑driven roadmaps for reducing cyber risk across identity, devices, apps, and data.
Microsoft continuously analyzes real‑world attack patterns across billions of signals. The result? A prioritized list of actions that deliver the highest measurable reduction in breach likelihood.
Here are the 10 Secure Score improvements that consistently deliver the biggest security gains, and why they matter.
- Enforce Phishing‑Resistant MFA (Top Risk Reducer)
Password‑based attacks remain the #1 entry point for breaches. Phishing‑resistant MFA, such as Microsoft Authenticator number matching, FIDO2 keys, or Windows Hello for Business, shuts down entire categories of credential‑theft attacks.
Why it matters:
- Stops phishing, replay, and MFA fatigue attacks
- Required for cyber insurance and many compliance frameworks
- Protects both IT and OT identities
- Apply Conditional Access for Risky Sign‑Ins
Conditional Access is Microsoft’s “if this, then that” policy engine for identity. High‑impact policies include:
- Block legacy authentication
- Require MFA for risky sign‑ins
- Require compliant devices for sensitive apps
Why it matters: Conditional Access is the backbone of Zero Trust, verifying every access attempt, every time.
- Disable Legacy Authentication (One of Microsoft’s Highest‑Value Actions)
Legacy protocols like IMAP, POP, and SMTP AUTH cannot enforce MFA and are heavily exploited by attackers.
Why it matters:
- Eliminates a massive attack surface
- Prevents password‑spray attacks
- Required for modern authentication and compliance
- Enable Safe Links and Safe Attachments
Email remains the most common initial attack vector. Microsoft Defender’s Safe Links and Safe Attachments provide real‑time scanning and detonation of malicious content.
Why it matters:
- Stops ransomware before it reaches users
- Protects Teams, SharePoint, and OneDrive, not just email
- Reduces human‑error risk
- Enforce Device Encryption (BitLocker)
Lost or stolen devices are a major data‑loss risk. BitLocker encryption ensures data is unreadable without proper authentication.
Why it matters:
- Required for most compliance frameworks
- Protects sensitive manufacturing IP
- Prevents breach escalation from compromised endpoints
- Require Device Compliance Policies
Secure Score heavily weights device compliance because unmanaged or non‑compliant devices are a top breach vector.
High‑value compliance controls include:
- OS version requirements
- Antivirus and EDR enforcement
- Disk encryption
- Block jailbroken/rooted devices
Why it matters: You cannot protect what you cannot manage, compliance policies ensure every device meets baseline security.
- Enable Admin Role Protection (PIM)
Privileged accounts are crown jewels for attackers. Azure AD Privileged Identity Management (PIM) enforces:
- Just‑in‑time access
- Approval workflows
- Time‑bound admin roles
Why it matters: Reduces standing admin privileges, one of the biggest risk reducers in any environment.
- Turn On Automated Threat Investigation & Response (AIR)
Microsoft Defender can automatically investigate suspicious activity and remediate threats.
Why it matters:
- Reduces response time from hours to minutes
- Ideal for lean IT teams
- Stops lateral movement early
- Protect Sensitive Data with DLP Policies
Data Loss Prevention (DLP) helps prevent accidental or malicious data exfiltration.
Why it matters:
- Protects customer data, IP, and regulated information
- Reduces insider‑risk exposure
- Supports compliance audits
- Enable Security Defaults (For Smaller Environments)
For organizations without complex Conditional Access needs, Security Defaults provide a strong baseline.
Includes:
- MFA for all users
- Blocking legacy authentication
- Modern authentication enforcement
Why it matters: A fast, free, high‑impact way to harden identity.
Why These Actions Matter for Manufacturers
Manufacturers face unique challenges:
- Shared workstations
- Remote plants
- Legacy OT systems
- Limited IT staffing
- High‑value IP targeted by nation‑state actors
These Secure Score actions directly reduce the most common attack paths used against manufacturing environments, especially identity‑based attacks, which now account for more than 80% of breaches.
