An in-house IT manager cannot be an expert in security, cloud, networking and support while also covering nights and weekends. Co-managed IT keeps your team in the lead and adds Quantum's monitoring platform, security stack, escalation engineers and project capacity.

Sound familiar?

  • Your one IT person can never take a real vacation
  • Security tooling is too expensive to license for a small team
  • Projects stall because daily tickets come first
  • You need senior expertise a few hours a month, not a hire

What's included

  • Enterprise monitoring and management tools for your team
  • Security stack: EDR, email security, backup, vulnerability scanning
  • Tier-2/3 escalation and specialist engineers
  • After-hours and vacation coverage
  • Project resources for migrations and rollouts
  • Documentation platform shared with your staff

Frequently asked questions

Will you replace our IT staff?

No. Co-managed IT is designed to make your internal team more effective and give them a bench to lean on.

Who owns the tools and documentation?

You do. Documentation lives in a shared platform, and we structure licensing so you are never locked out if the relationship changes.
