Built for Manhattan professional-services firms

Law firms, financial advisors, medical practices, and creative studios all share the same three IT problems: identity, endpoint security, and backup. We solve those three properly, then keep them boring — so your team can bill hours instead of fighting their laptops.

What “managed” actually includes

Full endpoint management (NinjaOne + Intune), Microsoft 365 administration (Entra, Exchange, SharePoint, Teams), immutable cloud backups, mail security, MFA/Zero Trust rollout, onboarding and offboarding runbooks, and quarterly business reviews. No per-ticket charges.
