What is co-managed IT support?

Co-managed IT combines your internal IT function with a defined external service. You keep strategy, budget and business relationships; DSC takes on the agreed support, engineering or security work.

That can mean specialist help for an established department, extra capacity across several sites, or cover for a smaller team.

Your IT leadership: Owns strategy, budget, business priorities and the decisions reserved to your team.
Named DSC contacts: A Service Desk Manager and Account Director, with technical and management escalation routes agreed at onboarding.
Existing systems: Supported tools and subscriptions can stay. We recommend changes for security, reliability, supportability, operational need or cost.

What co-managed support adds.

Use the partnership where it adds capacity: escalations, specialist engineering, planned cover and decisions that need another experienced view.

Monthly reporting records activity, risks, recovery checks and agreed actions. Reviews give your IT lead a place to prioritise the next work.

Augment your teamEscalation support, an agreed share of the queue and planned capacity for the work your team cannot absorb.
A virtual CTO on demandArchitecture, security design and roadmap input for your leadership team, scoped as engineering or advisory time.
Cover for the gapsHoliday, sickness and peak-demand cover planned in advance. Extended hours and emergency cover are agreed separately.
Agreed in writingSupported systems, owners, response targets, approval rights and the point at which work becomes a separately scoped project.

Signs it is time to bring in a co-managed partner.

Operational demand consumes project timeSupport across users, locations and suppliers leaves little room for migrations or infrastructure improvements.
Specialist work has no clear ownerIdentity, security operations, recovery or architecture needs more depth than the current team can provide.
Assurance work is growingISO 27001, Cyber Essentials and client due diligence need current evidence and a record of decisions.
Cover depends on a few peopleA small team or a specialist role needs holiday cover, documented procedures and another escalation route.

How much does co-managed IT support cost?

Start with the per-user platform fee, then add a committed engineering block. All figures below exclude VAT.

Co-managed platform: From £22per user, per month, plus engineer time
2 engineering days a month: £1,200per month, in addition to the platform fee
4 engineering days a month: £2,200per month, in addition to the platform fee

The platform fee covers monitoring, patching, the security baseline and escalation. Engineer time is bought as a committed monthly block.

We quote against the users or devices, systems, sites and functions you ask us to cover. Additional projects, extended hours and supplier subscriptions are identified separately.

Support and escalation

Your team: Business risk decisions, system ownership and approval of actions that could interrupt operations.
DSC: Configured monitoring, patching and the security services in scope. Where managed backup is included, daily checks and monthly restore tests.
Agree before service starts: The monitored estate, MDR arrangements, alert routing, containment authority, recovery priorities and human response hours.

Projects, migrations and change

Your team: The business case, priorities, access to system owners and approval of the change and its acceptance criteria.
DSC: Agreed design and engineering work, such as Microsoft 365, server or cloud migrations. Test results and a documented handover.
Agree before work starts: Scope, dependencies, change windows, recovery steps, budget and the work included in the monthly time block.

Governance and technical leadership

Your team: Policy ownership, risk acceptance, budget and reporting to your leadership or board.
DSC: Technical recommendations, service reporting, evidence and roadmap input. Named owners for agreed actions.
Agree before service starts: Review frequency, required reports, evidence access, decision makers and the route for unresolved risks.

Common questions

What's the difference between co-managed and fully managed IT?

With co-managed IT, your internal function keeps agreed responsibilities and DSC supplies defined support, engineering or security services alongside it. Fully managed IT gives DSC responsibility for running the agreed IT service. Both models need a service schedule covering systems, decisions, service hours and escalation.

Will you replace our internal IT person?

Co-managed support works alongside your existing person or team. They retain business relationships and the responsibilities you choose to keep. We add agreed capacity, specialist engineering and cover. The model also works with established IT departments supporting several sites.

How is co-managed IT priced?

The platform starts at £22 per user per month, plus committed engineering time, excluding VAT. Published blocks are 2 days for £1,200 or 4 days for £2,200 per month. The written quote records supported systems and responsibilities. See our pricing.

Do you cover out-of-hours and emergencies?

Extended support and emergency cover can be agreed separately. Our standard service window is 9am to 5.30pm, Monday to Friday, excluding England and Wales public holidays. Configured monitoring runs continuously; human investigation and response follow your contracted hours. We record escalation contacts and response targets before service starts.

Can co-managed support help with security and compliance?

Yes. We can take on agreed security operations, MDR arrangements, technical remediation and evidence work. DSC is an appointed Cyber Essentials and Cyber Essentials Plus certification body, and is ISO 27001 certified by a UKAS-accredited certification body. Your organisation retains its policy and risk decisions. See our cyber security services and governance and audit.
