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
