Managed IT vs In-House IT for Manufacturing Companies: Real Cost Comparison

For manufacturing companies, deciding between managed IT and in-house IT is not merely a matter of price, but also of risk, downtime, and operational continuity. While an in- house IT solution may seem less expensive at first, it has many hidden costs (downtime, security gaps, turnover). Managed IT provides stable expenses, improved cybersecurity, and round-the-clock support. Usually, in the manufacturing industry, the risk of downtime and cyber threats is a more critical factor than the savings on salaries.

Often, the best solution is a hybrid IT model, where internal teams are backed up, not bought out, by external professionals.

What is the difference between managed IT and in- house IT?

Managed IT refers to an outsourcing model where IT operations, security, and support are handled by a third-party provider. On the other hand, in- house IT depends on internal staff for systems, infrastructure, and troubleshooting management.

Why This Decision Is Different for Manufacturing

Manufacturing IT isn't like office IT. It directly affects production.

Key differences:

  • IT failure can stop production lines
  • Systems include OT (Operational Technology), like PLCs and SCADA
  • Many environments rely on legacy systems that are hard to secure
  • Multi-site plants increase complexity

According to the Cybersecurity and Infrastructure Security Agency, manufacturing is a frequent target due to its operational impact and supply chain dependencies.

Real Cost Comparison: In-House vs Managed IT

True Cost of In-House IT

Most companies underestimate internal IT costs.

  • Salaries + benefits (often 20-30% above base salary)
  • Tools (RMM, security, backup, monitoring)
  • Training and certifications
  • After-hours coverage gaps
  • Downtime risk
  • Security limitations
  • Hiring delays and turnover

Data from the U.S. Bureau of Labor Statistics shows IT salaries are only part of total employment cost benefits, and overhead significantly increases total spend.

Managed IT Cost Structure

  • Fixed monthly subscription
  • Tools and platforms included
  • 24/7 monitoring and response
  • Access to specialized expertise (security, compliance)
  • Scalable support as operations grow

The Hidden Cost of Downtime in Manufacturing

Downtime is the cost most companies ignore and it's often the largest.

When IT fails:

  • Production stops
  • Orders are delayed
  • Revenue is lost
  • Supply chains are disrupted

There is no universal downtime cost; figures vary widely by plant, but industry research from the International Society of Automation and Siemens consistently shows downtime as a major operational risk.

Cybersecurity Risk: The Cost Most Companies Ignore

Manufacturing is now one of the most targeted sectors.

  • Verizon DBIR reports consistently rank manufacturing among the top attack targets
  • IBM Security (2024) states that the cost of a breach can range in the millions of dollars worldwide
  • Ransomware can stop production completely

Frameworks like the National Institute of Standards and Technology (NIST) require a focus on layers of security and monitoring/response efforts that are difficult to achieve internally.
Reality: Choosing an IT model = choosing your risk exposure level

When In-House IT Makes Sense

  • Single-site operations
  • Limited regulatory or compliance pressure
  • Low cybersecurity exposure
  • Strong internal expertise already in place

When Managed IT Makes Sense

  • Multi-site manufacturing operations
  • The internal IT team is overloaded
  • Increasing cybersecurity threats
  • Compliance requirements (NIST, CMMC readiness)
  • Need for predictable IT costs

The Reality: Co-Managed IT (Best of Both)

Most manufacturing companies don't fully outsource and shouldn't.

How it works:

Internal IT:

  • Handles plant-specific systems
  • Manages vendors and operations

Managed IT provider:

  • Delivers cybersecurity
  • Monitors systems 24/7
  • Supports compliance readiness
  • Provides escalation and expertise

This is where Consilien operates, augmenting internal teams, not replacing them.

Decision Framework: What Should You Choose?

Choose In-House IT if:

  • Your environment is simple
  • Downtime risk is low
  • You have strong internal expertise

Choose Managed IT if:

  • You need 24/7 coverage
  • Security risk is increasing
  • IT complexity is growing

Choose Co-Managed IT if:

  • Your internal team is stretched
  • You need better security and compliance
  • You want to keep control but reduce risk

Frequently Asked Questions

Is managed IT cheaper than in-house IT?
Often yes, especially for mid-sized manufacturers. In-house IT looks cheaper on a salary line item, but once you add benefits, tools (RMM, EDR, SIEM, backup), training, after-hours coverage, and the cost of unplanned downtime, the true number is typically higher than a managed IT subscription. U.S. Bureau of Labor Statistics data shows IT compensation continues to rise, while managed IT pricing is fixed and predictable.
Can you combine managed IT with internal IT?
Yes. This is called the co-managed IT model and it is the most common setup for manufacturers who already have an internal team. The internal team handles plant-specific systems and vendor relationships; the managed IT partner delivers 24/7 monitoring, cybersecurity, compliance support, and specialized escalation. It is a force multiplier, not a replacement.
How much downtime can an IT failure cause?
There is no universal figure; downtime cost varies by plant size, product type, and recovery readiness. Industry research from the International Society of Automation and others routinely lists unplanned downtime as a top operational risk for manufacturers, with single-day outages capable of producing six-figure losses for mid-sized operations.
What's the biggest risk of in-house IT?
Single-point-of-failure risk. One IT person on vacation, sick leave, or quitting can leave a manufacturer exposed for days. Combined with the cybersecurity coverage gap (most in-house teams cannot offer 24/7 SOC monitoring or specialized incident response), this is the failure mode that drives most mid-market manufacturers toward managed or co-managed IT.
Does managed IT support compliance requirements like NIST and CMMC?
Yes. A qualified managed IT provider builds compliance into the operating model rather than bolting it on. The NIST Cybersecurity Framework is the foundation for most manufacturing security programs, and CMMC builds on top of NIST 800-171 for defense supply-chain manufacturers. Managed providers deliver the monitoring, evidence collection, and policy documentation auditors expect.
How big does a manufacturer have to be before in-house IT makes sense?
Most manufacturers do not reach the headcount where a fully in-house IT department makes economic sense until somewhere north of 500 employees with multiple sites and dedicated specialists for security, networking, ERP, and OT. Below that, the co-managed model almost always wins on cost, resilience, and coverage. The Verizon Data Breach Investigations Report consistently ranks manufacturing as a top-five attack target, and that risk profile is hard to defend with a small internal team alone.

Understand Your IT Risk Before It Impacts Production

If you're unsure where your vulnerabilities are-or your team is already stretched-now is the time to take a closer look. We'll help you identify gaps, reduce downtime risk, and build a model that supports your operations without replacing your team.
