What we operate

Day-to-day administration, end-to-end.

Nine disciplines under one team. We pick up your tenant where it is, harden the gaps, and run it forward without surprises.

Tenant configuration

Subscriptions, domains, organizational settings, and tenant-wide policies aligned to your compliance posture.

User lifecycle

Joiner / mover / leaver workflows. Provisioning, license assignment, group membership, and clean off-boarding.

Identity & MFA

Conditional access, sign-in risk policies, MFA enforcement, and privileged identity management with break-glass accounts.

Security baselines

Defender for Office 365, anti-phishing, attachment sandboxing, URL detonation. We tune thresholds for actionable signal, not noise.

License optimization

Audit underused licenses, right-size your tier mix, surface savings without taking features away from users who use them.

Compliance & audit

Retention policies, eDiscovery, audit log review, DLP rules, and USA data residency configuration where required.

Reporting & analytics

Monthly tenant health reports, login analytics, license usage trends, and security incident summaries, written so leadership can read in five minutes.

Migration & co-existence

From G Suite, on-prem Exchange, or legacy M365. Hybrid co-existence during cutover. Mailbox migrations run outside business hours.

Backup & recovery

Third-party backup of mailboxes, OneDrive, SharePoint, and Teams. Granular restore. Backups verified weekly, not just scheduled.

Why GR IT

What sets our M365 admin team apart.

Four facts about how we operate. Concrete, not aspirational.

Microsoft CSP since 2022

Direct billing relationship with Microsoft means licensing escalations go through partner channels, not consumer support queues.

500+ tenants under management

Pattern recognition across hundreds of USA deployments. We have already seen the issue you are about to hit.

5-minute P1 SLA, 24/7

Round-the-clock administration from a US-based team. Real engineers responding, not first-line ticket triage.

USA data-residency depth

Tenant provisioning in Microsoft's USA region with compliance documentation for DPL, NYDFS Part 500, and Wall Street requirements.

Industries we work with

Microsoft 365 for the way your sector actually works.

Six verticals where we run M365 day-to-day. Different compliance constraints, different DLP rules, different user-lifecycle realities, same managed-administration layer underneath.

Real estate

Heavy SharePoint use for property files, automated workflows for tenant onboarding, mobile-first access for site visits and inspections.

Healthcare

Clinics, hospitals, and medical groups. Patient data segmented through sensitivity labels, retention policies aligned to USA healthcare regulations.

Financial services

Asset managers, family offices, and fintech. Conditional access for regulated work, dedicated DLP rules for client communications.

Hospitality

Hotels and restaurant groups. Front-of-house Outlook for reservations, back-office SharePoint for SOPs, Teams for shift coordination.

Trading & logistics

Multi-entity trading houses with offices across MENA. Cross-tenant licensing, regional admin delegation, audit logs by entity.

Professional services

Law firms, accounting practices, consulting groups. Information barriers, eDiscovery readiness, client-confidentiality DLP rules.

Self-managed vs managed

What you actually get.

A side-by-side of the gaps we see most often when we audit a tenant that has been running self-managed for a year or more.

How it works

A clear engagement model.

Whether we are taking over an existing tenant or building a new one, the engagement runs through these four stages.
  1. 1

    Discovery & audit

    1-2 days

    Free one-hour audit of your existing tenant, MFA coverage, conditional access, license usage, Defender baseline, DKIM/DMARC alignment. Output: a written remediation plan you can accept or adjust.

  2. 2

    Remediation

    1 week

    Apply security baselines, close MFA gaps, tune Defender, clean up licensing. Communicated in advance, executed in scoped change windows.

  3. 3

    Operations

    Ongoing

    Day-to-day administration: tickets, change requests, monitoring, monthly health reports. Priority-tiered SLAs (P1 5min · P2 10min · P3 30min).

  4. 4

    Strategic review

    Quarterly

    Tenant health, compliance posture, license optimization, and roadmap. The output is a written summary your leadership can read in five minutes.

We migrated from on-prem Exchange to Microsoft 365 with GR IT across two weekends, both invisible to staff. The follow-up review caught two policy gaps before they became audit findings. We have since folded their team in as our managed M365 admin.
