Each service below addresses a specific gap in how most Greater Baltimore businesses are running Microsoft 365 today. Here is what each one does, what it prevents, and what happens to organizations that skip it.
Microsoft 365 Migration
M365 Migration and Tenant Deployment
Complete migration from Google Workspace, on-premises Exchange, hosted email, or another M365 tenant — including mailbox migration, calendar and contacts, SharePoint and Teams buildout, and DNS cutover. We stage data migration in the background and minimize cutover downtime to under an hour. Post-cutover, we configure the tenant’s security baseline before the first user logs in, so the environment is never running at default settings.
Covers: Exchange Online mailbox migration, SharePoint site and document library setup, Teams structure and governance, OneDrive configuration, DNS and MX record cutover, user onboarding.
Without it: migrations handled without a security-first configuration step deliver a tenant that is live, functional, and fully exposed — MFA off, sharing wide open, Defender at minimum sensitivity.
Microsoft Entra ID
Identity and Access Management (MFA + Conditional Access)
Entra ID (formerly Azure Active Directory) controls who can sign into your Microsoft 365 environment and from where. We enforce multi-factor authentication for every user, configure Conditional Access policies that block logins from unrecognized devices and high-risk sign-in locations, and apply Privileged Identity Management for administrator accounts. This is zero trust identity: no login is trusted by default. For defense contractors, Entra ID Conditional Access maps directly to the NSA at Fort Meade 800-171 access control requirements under CMMC Level 2.
Prevents: account takeover via stolen credentials, login from unauthorized devices, admin privilege abuse, credential stuffing attacks.
Without it: a phished or reused password opens your entire M365 environment — mail, files, Teams, and every connected application. Missing MFA documentation is the most common reason cyber insurance claims are denied.
Microsoft Defender for Office 365
Email Security and Anti-Phishing
Defender for Office 365 Plan 1 and Plan 2 deliver Safe Attachments (detonating suspicious files in a sandboxed environment before delivery), Safe Links (real-time URL scanning at click time), anti-phishing policies, and spoof intelligence. We configure DMARC, DKIM, and SPF records so attackers cannot impersonate your domain when emailing your clients. DMARC enforcement is a CMMC Level 2 requirement and a growing expectation from cyber insurance underwriters. For Greater Baltimore maritime law firms and professional services companies, domain spoofing prevention is a direct defense against the business email compromise that cost $16.6 billion in FBI-reported losses in 2024.
Prevents: phishing credential harvesting, malicious attachment delivery, domain spoofing for BEC, zero-day email exploits.
Without it: M365’s default anti-spam filtering blocks obvious junk but misses sophisticated phishing campaigns built specifically to impersonate known senders and evade signature-based filters.
Microsoft Intune
Device Management and Compliance Enforcement
Microsoft Intune enforces device compliance policies — encryption, screen lock, OS patch level, and approved application installation — before a device is allowed to connect to Microsoft 365. Conditional Access policies tied to Intune block non-compliant or unmanaged devices from accessing Exchange, SharePoint, and Teams. For healthcare organizations, device management is part of the HIPAA Security Rule’s workstation use and workstation security controls. For defense contractors, it supports the NSA at Fort Meade 800-171 control 3.1.18 (control the connection of mobile devices) under CMMC Level 2.
Prevents: unpatched device access, personal device data leakage, lost device exposure, non-compliant endpoint access to regulated data.
Without it: a personal phone running an outdated OS with no encryption and no remote-wipe capability has the same access to your Exchange mailbox and SharePoint files as a managed corporate laptop.
Microsoft Purview
Data Governance and Compliance (DLP, Sensitivity Labels, eDiscovery)
Microsoft Purview provides data loss prevention policies that detect and block sharing of regulated data — PHI patterns for HIPAA, CUI markers for defense contractors, PAN data for PCI scope. Sensitivity labels classify documents and enforce encryption and access restrictions throughout their lifecycle, whether the file is in SharePoint, emailed, or saved to a USB drive. eDiscovery and retention policies support litigation holds and regulatory record-keeping requirements. For defense contractors, Purview sensitivity labels configured to mark CUI documents support the NSA at Fort Meade 800-171 control 3.13.16 under CMMC Level 2.
Prevents: accidental PHI sharing via SharePoint, CUI exfiltration via email, litigation hold failures, uncontrolled document access by former employees.
Without it: any user can email a SharePoint folder containing patient records to a personal Gmail address, and the system will complete the action without warning or logging.
SharePoint and Teams Governance
SharePoint and Teams Governance
Left unmanaged, Microsoft 365 tenants accumulate hundreds of Teams channels, SharePoint sites, and guest accounts created ad hoc by users without guardrails. We implement governance policies: Teams creation controls, lifecycle management with automated expiration and review, guest access policies with regular review cycles, external sharing settings locked to the minimum necessary, and sensitivity labels applied to Teams and SharePoint sites to enforce data handling rules. For Baltimore hospitality businesses, SharePoint external sharing policies keep payment-adjacent document libraries out of reach of anonymous link sharing.
Prevents: data sprawl, orphaned guest access, accidental public document exposure, compliance scope creep from unmanaged Teams.
Without it: three years of ungoverned Teams growth leaves you with 200 channels, 40 guest users from vendors who left two years ago, and no visibility into which SharePoint sites are sharing what with whom.
Third-Party M365 Backup
Microsoft 365 Backup
Microsoft’s built-in retention covers platform failures but does not protect against ransomware-driven cloud file encryption, accidental deletion beyond the recycle bin window, or malicious insider deletion. We deploy independent, immutable third-party backup covering Exchange Online, SharePoint, OneDrive, and Teams — with configurable retention up to seven years for healthcare and legal compliance requirements. Recovery is granular: a single email, a document version, or an entire mailbox, restored in minutes from a clean, attacker-inaccessible copy. For Maryland-regulated healthcare providers, documented backup and recovery procedures are part of the HIPAA Security Rule’s contingency plan standard.
Prevents: permanent data loss from ransomware, accidental deletion beyond Microsoft’s retention window, insider threat data deletion, compliance retention failures.
Without it: Microsoft’s own service agreement recommends third-party backup. When ransomware encrypts OneDrive-synced files and version history is exhausted, the answer is “data is gone” — not “restored in an hour.”
Microsoft 365 GCC and GCC High
GCC and GCC High for Defense Contractors
Commercial Microsoft 365 plans do not meet DFARS 252.204-7012 requirements for Controlled Unclassified Information. GCC (FedRAMP Moderate authorized) is the minimum environment for most DoD CUI and satisfies DFARS baseline requirements. GCC High (FedRAMP High authorized) is required for ITAR-controlled technical data and certain sensitive CUI categories. We assess which environment your program data requires, manage GCC/GCC High tenant provisioning and eligibility documentation, migrate mailboxes and SharePoint content from your commercial tenant, configure the security baseline, and maintain the environment to CMMC Level 2 standards. Greater Baltimore defense contractors tied to the HII the federal contracting corridor supply chain, Johns Hopkins programs, and JBLE should assess GCC/GCC High need today — not when a prime contractor asks for proof.
Prevents: DFARS violation for CUI in a non-compliant environment, False Claims Act exposure, contract ineligibility.
Without it: storing CUI in a commercial M365 tenant is a DFARS violation regardless of how many other security controls are in place. The environment itself must be FedRAMP Moderate authorized at minimum.
