Co-Managed IT Services
Build a Stronger IT Department. Keep Full Control.
Give Your IT Department the Bandwidth to Do More
Your IT team knows your business. But between keeping systems stable, supporting users, and delivering projects, there isn’t enough time for the work that moves the business forward.
The Problem
Without extra capacity, you end up choosing between:
- Delaying projects and improvements
- Pushing upgrades and cybersecurity to “later”
- Burning out the team trying to do it all
The S3 Co-Managed Approach
We don’t replace your team, we strengthen it.
Every co-managed partnership starts with our Infrastructure Management foundation so your core systems are monitored, patched, and running smoothly 24/7.
From there, you choose the modules you want:
- User Support (Helpdesk, 7–7 + 24/7 emergency): Ultra-fast response by chat, phone, email; AI-assisted triage; vendor coordination; remote & onsite; full ticket transparency and user portal.
- Cybersecurity (SOC & IR): Real-time monitoring and incident response; EDR, SIEM, DNS filtering; compromised credential monitoring; vulnerability scanning; patching; awareness training; compliance support.
- Strategic IT Planning (vCIO): Annual alignment sessions; 3-year roadmap & budget; stack recommendations; board-ready materials and presentation support.
- Project Execution & Management: Dedicated PM; delivery across Microsoft 365, Azure, Windows Server, VMware, Fortinet; clear scope, timelines, and accountability.
- Shared Tools & Automation: PSA/RMM/monitoring, documentation, self-service portals, and AI/automation to speed up assignment, prioritization, and resolution.
You keep control and visibility. We do the heavy lifting.

Frequently Asked Questions
The main difference between co-managed and managed IT services lies in the level of involvement and control your business retains over its IT operations.
Our Managed IT Services are a complete outsourcing solution where we manage all aspects of your IT infrastructure. This includes day-to-day management, cybersecurity, and strategic planning, allowing you to focus on core business functions without the complexities of IT management. It’s ideal for businesses without an in-house IT team or those looking to free up internal resources.
Our Co-Managed IT Services, in contrast, are a collaborative approach designed to complement your existing in-house IT team. We provide additional expertise, resources, and tools to fill gaps, handle specific projects, or offer specialized skills your team might lack. This model maintains your internal control over IT operations while offering the flexibility to scale support as needed.
Key Differences:
- Control: Co-managed services allow businesses to maintain greater control within their IT operations, whereas managed services are more hands-off, with our team taking full responsibility.
- Flexibility: Co-managed IT provides tailored support to meet specific needs, making it highly flexible, while managed IT offers a comprehensive, all-in-one solution.
- Target: Co-managed services are best for businesses with an existing IT team needing extra support, whereas fully managed services are suited for businesses looking to outsource their IT.
Absolutely! Our co-managed IT services model is built on flexibility and customization to meet your specific business needs. We understand that every one of our clients has unique requirements and capabilities, and our goal is to complement your in-house IT team.
It depends on your preferences. For some clients, we fully manage the cybersecurity stack—EDR, SIEM, patching, training, monitoring, and more.
For others, cybersecurity is handled internally by their IT team or outsourced to a third-party provider. We’re flexible and adapt to the model that works best for you.
That’s normal. It’s common for clients to start with infrastructure only and later add cybersecurity, projects, or user support. Sometimes the opposite happens: an IT team may take back user support in-house. Our agreements are flexible, and we adjust as your team and business evolve.
