Sound Familiar?
If you're nodding along, you're not stuck. We have handled these switches before, including difficult handovers where the outgoing provider didn't cooperate, and we can get you there safely.
See if Nimbus is the right fitHow Nimbus Works
Everyone says "proactive." When did your MSP last prove it?
"Proactive" is the most overused word in IT. Most providers say it, then wait for your call. So ask yourself: when did yours last reach out, unprompted, to tell you about something they had already done for you, and why it mattered for your business? If you can't remember, that's reactive with better marketing. Nimbus works the other way, with daily security monitoring, proactive patching, and continuous compliance review that happen before you notice, and we tell you what we did and why it protects you.
We build the security foundation most providers skip.
Strong IT starts beneath the surface: Microsoft 365 hardened and configured correctly, identity protected with Conditional Access and multi-factor authentication, devices enrolled and managed through Intune, and backups that are tested with confirmed restores. We build this baseline at every client, without exception. It is not an upsell, and it is never a stripped-down tier. It is the foundation every Nimbus engagement starts from.
We go beyond IT into compliance and strategic guidance.
For growing businesses, IT support is only the beginning. Nimbus gets you cyber-insurance ready, with the controls and documentation your carrier and auditor actually want to see, plus business reviews, vCISO advisory, and Illinois compliance support when your industry calls for it. We are not just your IT company. We are the security and compliance partner your business needs as it grows.
What's Included
Responsive help desk, Microsoft 365 administration, device enrollment and management, patch management, daily monitoring, and user lifecycle management, all included in your monthly plan. No surprise hourly charges. No per-ticket billing.
Defender XDR, Conditional Access, identity protection, security awareness training, penetration testing, tested backups with confirmed restores, cyber insurance readiness, and Illinois compliance support when your industry needs it. Security is the floor at Nimbus, not an add-on and never a tier.
Business reviews, vCISO services, cyber insurance evidence packages, and IT project delivery for migrations, infrastructure upgrades, and environment transitions. We are a long-term strategic partner, not just a helpdesk.
