Questions we actually get
Straight answers about fit, scope, and how we work.
Book a call →What does managed IT from Limehawk cost?
Base managed IT is month-to-month with a 3-user minimum: unlimited user support plus the core security suite (endpoint detection and response, email filtering, and password management). Add-ons like managed firewalls, hosted phones, and server management are scoped on a call.
Why do you publish your incident reports?
Because every IT company says they're proactive and responsive, and none of them show their work. Each report documents a real problem, what we did, and what it cost the client in downtime. You can read exactly how we operate before you ever talk to us.
Who actually does the work?
Limehawk is a Knoxville managed service provider led by Corey Watson, who writes every report on this site. When you call, you reach the team that does the work, not an offshore call center and not a sales rep.
What areas do you serve?
We're headquartered in Knoxville and serve businesses across East Tennessee. Most of our work (monitoring, patching, security response, Microsoft 365 administration) is delivered remotely, with on-site visits when the problem calls for it.
What kinds of businesses do you work with?
Small and mid-sized businesses that depend on their technology: title companies, law firms, accounting firms, medical practices, insurance agencies, and manufacturers. If a computer problem costs you billable hours or a closing, we're built for you.
How do we get started?
Book a call. You'll talk to Corey. Fifteen minutes, no sales deck. If we're a fit, onboarding typically means deploying our management agent, a security baseline pass, and documenting your environment in the first two weeks.
