Establishing a Microsoft 365 identity risk baseline across every managed service provider (MSP) client is essential to delivering consistent, secure outcomes at scale. By creating a repeatable identity security standard, MSPs can reduce the frequency of account compromises, limit privilege abuse, and reveal risk exposure before it escalates into a breach. The core principle: standardize identity safeguards everywhere, adapt exceptions openly, and continuously audit for configuration drift so no tenant slips below the minimum bar.
Definition: Microsoft 365 Identity Risk Baseline for MSPs
A Microsoft 365 identity risk baseline is a documented, enforceable standard that defines minimum security controls for all client tenants. It typically includes requirements around multi-factor authentication (MFA), legacy authentication blocking, Conditional Access, privileged account management, emergency access accounts, audit logging, and application consent review. The intent is not cookie-cutter conformity, but a repeatable minimum security posture MSP-wide.
Why an Identity Risk Baseline Is Central for MSP Clients
Identity is the foundation of Microsoft 365 security, acting as the core control for access to email, files, admin functions, and third-party integrations. Unlike firewall or endpoint policies, weak or inconsistent identity controls almost always lead to compromise—from hijacked mailboxes to attacker lateral movement across services. For MSPs, sustaining a baseline is about scaling trust: one slip on a single tenant exposes client data, damages reputation, and adds avoidable support and escalation costs.
In practice, the challenge isn't knowing which controls are important, but maintaining the same level of protection across dozens, or hundreds, of clients—each with unique apps, exceptions, and business requirements. That’s why the baseline must be templated, documented, and subject to continuous validation—a process where a unified platform like Ixvara becomes critical for centralized visibility and control.
Core Elements of a Microsoft 365 Identity Risk Baseline
- MFA Enforcement for all users (especially admins)
- Legacy Authentication Blocking (disabling basic auth protocols such as POP, IMAP, SMTP AUTH)
- Conditional Access Policies to automate sign-in requirements and reduce attack surface
- Privileged Role Protection (separate admin accounts, minimal roles, just-in-time elevation)
- Emergency/BREAK GLASS Accounts documented, tested, and excluded from restrictive policies
- Application Consent Control (managing OAuth grants and reviewing third-party access)
- Audit Logging and Sign-In Review (continuous log monitoring and alerts)
Step-by-Step: Building the Baseline Across MSP Clients
Step 1: Document a Reference Standard
Start by reviewing your most secure tenant and comparing its settings to respected frameworks (such as Microsoft Secure Score and CIS benchmarks). Use this as the blueprint for the baseline. Write down exactly what is required:
- Who must use MFA? (answer: everyone, with exceptions documented)
- Which legacy protocols are blocked?
- What are the names, roles, and lifecycle of admin accounts?
- Do emergency accounts exist, and how are they protected?
Step 2: Policy Naming and Ownership
For cross-tenant clarity, standardize naming conventions such as SEC-MFA-ALL-USERS or SEC-CA-BLOCK-LEGACY-AUTH. Assign owners to each policy. Without explicit owners and review dates, key settings are easily forgotten as staff turn over.
Step 3: Separate Baseline from Exceptions
Do not dilute the baseline with tenant-specific exceptions. List the minimum requirements in one place and manage client deviations in a separate register. Good exceptions are temporary, well-justified, and reviewed regularly. Bad exceptions are unclear or permanent.
Step 4: Phased Rollout to Minimize Disruption
- Deploy policies in report-only mode where possible
- Pilot changes with a small group
- Monitor for unforeseen failures or business process impact
- Transition to enforcement tenant by tenant
- Document the status and a rollback plan
This phased approach is especially valuable when enabling Conditional Access or blocking legacy authentication, as business-critical apps or devices may be affected.
Step 5: Build in a Monthly Drift Review
The baseline can slip as changes are made, roles are reassigned, or new admins join. Schedule regular reviews:
- Weekly – Review risky sign-ins and admin activity
- Monthly – Inspect Conditional Access, MFA exceptions, app consent changes
- Quarterly – Audit privileged roles, emergency account integrity, and gap analysis
- After Incidents – Update standards based on lessons learned
A Practical MSP Identity Checklist
Every client should have, at minimum:
- MFA enforced (all users and admins)
- Legacy authentication blocked
- Conditional Access for risky sign-ins and privileged app access
- Separate admin identities, used only for administration
- Break-glass accounts validated and documented
- Audit logging enabled, reviewed regularly
- App consent disabled for standard users (unless needed, with documented exceptions)
- Mailbox forwarding and risky sign-in alerts configured
Where MSPs Often Go Wrong (and How to Avoid It)
- Treating identity hardening as a "set and forget" project
- Copy-pasting policies across tenants without checking fit or licensing
- Leaving legacy auth enabled for "one old device" that never gets replaced
- Granting full admin access for day-to-day tasks
- Allowing uncontrolled OAuth app consent
- Neglecting audit logging because "clients don’t see it"
- Skipping regular drift reviews after projects complete
To avoid these pitfalls, MSPs need cross-tenant visibility, tight process ownership, and an operational platform that connects the dots between identity, service desk, and infrastructure. This is where Ixvara provides distinct advantages, consolidating alerts, policy drift, privileged activity, and risky access in a unified layer for fast root cause analysis and action.
Ixvara’s Role in Sustaining a Microsoft 365 Identity Baseline
Maintaining a risk baseline for Microsoft 365 identities is not just about what controls are set, but about keeping them consistent as organizations and their users change. Ixvara is purpose-built to:
- Correlate identity events with service desk data and device inventory
- Surface and triage risky sign-in patterns and privilege changes automatically
- Monitor configuration drift, so when a baseline is violated, actions can be triggered in real time
- Reduce escalation by equipping Tier 1 support with the same context as senior engineers
For MSPs, this unified approach means lower operational overhead, higher consistency across tenants, and the ability to scale without adding engineering headcount—all outcomes that reinforce business value and client trust.

Measuring Success: Operational Metrics for Your Identity Baseline
- Percent of users and admins covered by MFA
- Number of open legacy authentication exceptions
- Count of privileged roles per tenant
- Volume of risky sign-in events per month
- Mean time to remediate identity alerts
- Total configuration drift incidents caught
Over time, these metrics should demonstrate improvement: fewer exceptions, faster closure of risky incidents, and higher policy compliance. If the numbers stall or worsen, review operational practices and increase review frequency.
Best Practices: Sustaining Identity Security Baselines
- Treat baselining as a continuous process, not a single project
- Automate reviews whenever possible to catch drift early
- Clearly document exceptions, including owner, justification, and expiration
- Test emergency accounts quarterly to avoid lockouts during incidents
- Regularly review app consent logs for unexpected access
- Empower service desk staff to act quickly when identity signals risk

FAQ: Microsoft 365 Identity Risk Baselines for MSPs
What is the main goal of a Microsoft 365 identity baseline for MSPs?
The main goal is to ensure a consistent, enforceable level of identity security for every managed tenant, reducing risk of compromise and eliminating siloed, ad-hoc controls.
How frequently should we review the baseline for each client?
Most MSPs benefit from weekly reviews of risky sign-ins and admin changes, monthly reviews of Conditional Access and exceptions, and quarterly privilege audits. Reviews should also occur after any major incident.
Why is blocking legacy authentication critical?
Legacy authentication bypasses modern controls like MFA and is a common vector for password spray and credential stuffing attacks. Blocking it is a high-return measure that significantly raises the security floor.
How should exceptions to the baseline be managed?
All exceptions must be clearly documented with a business owner, valid use case, and review or removal date. Avoid open-ended exceptions, as they quickly become permanent risks.
How does Ixvara help with identity baselines?
