Microsoft 365 — secure by baseline, not by hope.
Conditional Access, identity hardening, Defender XDR, audit logging, DLP, Purview. Configured to your tenant baseline with documented evidence, monitored under our SOC.
Microsoft 365 hardening scope
Conditional Access policies
Risk-based sign-in, device compliance, named locations, app-based access. Reviewed monthly, exception register maintained.
Identity hardening
MFA enforcement, passwordless rollout where supported, privileged identity management (PIM), break-glass account hygiene, guest-access governance.
Microsoft Defender XDR
Defender for Office 365 (email), Defender for Endpoint, Defender for Identity, Defender for Cloud Apps — tuned, not factory-default.
Audit logging + retention
Unified audit log enabled, exported to a SIEM you own, retention aligned to your compliance scope (90 days minimum for most baselines).
DLP + sensitivity labels
Microsoft Purview policies for ePHI, PCI, PII, or CUI scope. Labels applied automatically where supported, with end-user-driven exceptions.
Monthly tenant report
Sign-in risk events, compliance posture deltas, license-cost optimizations, recommended Conditional Access changes — sent to your executive team.
What an M365 hardening assessment delivers
A line-item posture review against the controls that actually matter. Sample shown, anonymized from a real engagement.
Conditional Access policy 'Require MFA for all users' active
3 of 5 Global Admins still on SMS — schedule cutover
Policy active; 0 legacy-auth sign-ins last 30 days
Entra ID P2 features available but not configured
DMARC at p=quarantine; ready to move to p=reject in 30 days
Mailbox-intelligence on; 4 executives in protected-users list
Dynamic delivery on; click-time URL rewriting active
Transport rule not deployed — recommended for BEC defense
Defender P2; 248 of 248 devices reporting
Windows compliant; macOS and iOS compliance policies pending
ASR rules not enabled — high-leverage hardening
Purview unlicensed or unconfigured
DLP on email only — extend to Teams, SharePoint, OneDrive
Audit log on; retention at default 180 days — extend to 365
Alerts firing into a shared inbox no one watches at 2 AM
Industries this fits best
The pattern works anywhere; these are where the operational lift is most visible.
Healthcare
HIPAA-aligned configuration, ePHI sensitivity labels, BAA-ready posture.
Financial Services
FFIEC-aligned identity controls, audit retention beyond regulatory minimum.
Legal
Privilege-preserving DLP, client-matter labeling, deletion-resistance review.
Professional Services
Client-data segregation across mailboxes, sites, and Teams.
Standard versions should be verified from the official source before contractual reliance.
Questions before we start.
We already pay for M365 E5 — what changes?
Licenses get you the features. They don't configure them. We turn the E5 stack from theoretical capability into measured, documented, monitored controls.
Will Conditional Access lock out our executives?
Not when designed properly. Rollout starts in report-only mode, exceptions are explicit, break-glass accounts are tested before enforcement. We've never locked an executive out of a tenant we configured.
Does this replace our existing EDR?
Not necessarily. Defender for Endpoint is excellent for Windows + macOS. If you run SentinelOne, CrowdStrike, or another EDR, we integrate rather than rip-and-replace.
