Group 4 Networks provides co-managed IT services to Toronto businesses that already have an internal IT lead or small team but need senior backup, after-hours coverage, security depth, or specialist capacity without hiring two more full-time engineers. Co-managed isn't outsourcing — your IT manager keeps strategic control, owns the relationships, and stays the face of IT to ownership. We slot in behind them: handling tier-2 and tier-3 escalations, running 24/7 monitoring, managing patching and backups, owning security operations, and stepping in when your internal lead is on vacation, in a project crunch, or facing something outside their experience. For Toronto firms in the $5M–$50M revenue range, this model typically costs 30–50% less than expanding the internal team and gives you immediate access to senior expertise you couldn't otherwise hire. We bring our toolset (Syncro, ScreenConnect, Huntress, SentinelOne) and our documentation discipline, but defer to your team's preferred ticketing system, change management, and reporting cadence. Common engagements look like: internal lead handles users and projects, G4NS handles infrastructure, security, and night/weekend coverage; or internal team owns daily operations, G4NS owns the quarterly strategy review and security posture. We work as a true extension of your team — joining your standups, attending your vendor reviews, and adding our name to internal documentation, not replacing it.
