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.

Sample shown. The full M365 posture assessment covers 60+ controls across Identity, Email, Endpoint, Data, Apps, and Audit. Evidence is collected directly from your tenant under a read-only delegated app permission.

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.

Frequently asked

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.
