Migrated Without Drama.
Hardened From Day One.
IntermixIT delivers Microsoft 365 hardening and migration services for businesses across Harrisburg, Lancaster, York, and Central Pennsylvania, moving email, files, and teams to the cloud without data loss, then locking the tenant down and managing it for the long run.
- Migrate email and files with zero data loss
- Lock down identities with MFA and access controls
- Meet HIPAA and insurance requirements
- Keep your tenant managed, monitored, and tuned
A Default Microsoft 365 Tenant Is an Open Door
Microsoft gives you the tools, not the configuration. Out of the box, weak MFA coverage, legacy protocols, and wide-open sharing leave most tenants far more exposed than anyone realizes. If something gets in through those gaps, it reaches the email, files, and calendars the whole company works from. IntermixIT migrates, hardens, and manages Microsoft 365 as one service.

FAQ
Microsoft 365 Questions, Answered
Straight answers about hardening, migration downtime, costs, and managed Microsoft 365.
What is Microsoft 365 hardening?
Hardening is the security configuration Microsoft leaves to you: enforcing MFA, blocking legacy authentication, controlling sharing, and monitoring the tenant.
A default Microsoft 365 tenant trades security for convenience. IntermixIT closes those gaps with conditional access, least-privilege admin roles, email protection, and 24/7 monitoring, then keeps the configuration current as Microsoft changes.
Will there be downtime during a Microsoft 365 migration?
With proper planning, downtime is minimal and usually invisible to your team.
We stage migrations so mail keeps flowing during cutover, files sync before switch day, and users are onboarded in waves with support standing by. Most teams simply log in Monday morning to a faster, cleaner environment.
How much do Microsoft 365 hardening and migration services cost?
Pricing depends on your user count, how much data is moving, and the level of hardening and ongoing management you need.
Rather than one-size-fits-all packages, IntermixIT builds agreements around your environment and budget. During your Discovery Session we review your tenant, identify the gaps that matter most, and recommend a plan with clear, predictable pricing.
Can you work with our internal IT team?
Yes. Co-managed Microsoft 365 gives your internal team enterprise tooling with our engineering depth behind it.
Many internal teams keep day-to-day administration and hand IntermixIT the security configuration, migrations, and monitoring. Your team stays in charge; we keep the tenant hardened.
How quickly do you respond to support requests?
Our average response time is 15 minutes, and most issues are resolved remotely.
When hands-on help is needed, our technicians, who are all IntermixIT employees, serve businesses throughout Harrisburg, Lancaster, York, Mechanicsburg, Camp Hill, Carlisle, and Central Pennsylvania.
How hard is it to switch providers or move tenants?
Easier than most businesses expect, and we manage the transition for you, including taking over an existing tenant.
Whether you are leaving another provider, consolidating tenants after an acquisition, or moving off on-premise servers, our structured onboarding documents everything, secures admin access, and migrates in stages with no gap in protection.
What is not included in Microsoft 365 services?
Migration, hardening, monitoring, and day-to-day management of your covered tenant are all included. Larger one-time efforts are scoped separately as projects.
Efforts such as multi-tenant consolidations, custom SharePoint development, and third-party application integrations are quoted as defined projects with clear pricing approved before work begins, so there are never surprise invoices.
Can you help with compliance and cyber insurance requirements?
Yes. Microsoft 365 configuration is central to most compliance frameworks and cyber insurance questionnaires.
IntermixIT aligns your tenant with HIPAA and PCI expectations through access controls, retention, encryption, audit logging, and the documentation to prove it. From healthcare practices to accounting and law firms, compliance support is built in.
