The Myth of the Solo IT Manager: Why Small Businesses Are Outgrowing the One-Person IT Department

For many small and medium-sized businesses, the idea of a “solo IT manager” has become almost mythical — a lone technical hero responsible for everything from resetting passwords to architecting cloud strategies, managing cybersecurity, supporting end users, deploying new systems, and keeping the entire business operational. It’s no doubt an appealing idea: one person, trusted and talented, handling all things technology. Affordable. Familiar. Convenient.

But as modern IT environments grow more complex — and as threats and expectations evolve — the myth of the all-capable, endlessly available one-person IT department is becoming increasingly risky and unrealistic.

In reality, the solo IT manager is expected to perform the work of an entire department. And while many IT professionals are incredibly capable, relying on one individual to “do it all” can expose an organization to significant operational, security, and financial risk. This blog post will break down why the solo-IT-manager model no longer fits today’s business landscape — and what small businesses should consider instead.

The Modern IT Landscape Has Outgrown One-Person Teams

Technology ecosystems have evolved far beyond the traditional help desk and basic server maintenance. Even the smallest businesses now rely on:

• Cloud infrastructure
• SaaS applications
• Mobile device fleets
• Identity and access management
• Cybersecurity monitoring and threat detection
• Compliance reporting
• Backup and recovery
• Network configuration
• Vendor management
• AI-powered tools and workflows

The list could be even longer for certain industries or companies. And each of these areas requires specialized knowledge not only to deploy, but to maintain, secure, and optimize.

A solo IT manager can be exceptional, could have experience in a variety of areas — but it’s impossible for one person to remain deeply knowledgeable in every discipline while also handling day-to-day support. The expectation isn’t just unrealistic; it’s unsustainable.

Security Threats Have Outpaced Single-Person Capacity

Cyberattacks are no longer just a concern for large enterprises. SMBs have become primary targets because they often lack the layered defenses and around-the-clock monitoring that larger businesses have. From 2024-2025, 72% of SMBs reported being affected by cyber crime.

A single IT manager simply cannot do all of these things alone:

• Monitor threats 24/7
• Perform continuous patching and vulnerability scanning
• Investigate suspicious activity in real-time
• Respond immediately during off-hours
• Stay current with every new exploit, trend, and security control
• Manage cyber insurance requirements
• Build and test a robust disaster recovery plan

Even for well-funded security teams, this work is challenging. For one person? It’s nearly impossible. When a business relies on one individual, a single phishing attack, misconfigured firewall rule, or unpatched system can spiral into a costly incident — not because their IT manager is unskilled, but because the workload is too large for one human being to handle.

The “Bus Factor” Problem

The bus factor is a measurement of the risk resulting from information and capabilities not being shared among team members, derived from the phrase “in case they get hit by a bus”. In this case, it refers to how vulnerable an organization is if the solo IT manager suddenly becomes unavailable. 

For example, if the solo IT manager is sick, on vacation, dealing with a family emergency, retires or resigns – the entire business is immediately exposed. Critical tasks will inevitably stall. Security monitoring stops. Problems begin to accumulate. And knowledge gaps become painfully visible. 

Companies often discover too late that their solo IT manager was also their:

• Only network engineer
• Only cybersecurity practitioner
• Only cloud admin
• Only SaaS administrator
• Only application support provider
• Only hardware technician

Losing that institutional knowledge can trigger costly downtime, delays, or forced rebuilds of undocumented systems. Or worse, if the solo IT manager doesn’t pass their knowledge onto the next person, key information could be lost forever. 

Burnout Is Inevitable (and Expensive)

Even highly skilled IT professionals are not immune to burnout — especially when they’re effectively running an entire department alone. Solo IT managers regularly juggle:

• Back-to-back help desk requests
• Strategic planning
• Security responsibilities
• After-hours emergencies
• Exec-level reporting
• Major infrastructure projects

This level of workload leads to chronic burn out. Under constant pressure, even the best IT professionals can struggle to keep up with documentation, patch schedules, or long-term planning. When the work overload hits, businesses often face high turnover — and a difficult, expensive recruiting process to replace them.

Technology Is Too Strategic to Be Handled by One Person

Businesses no longer view IT as a “support function.” It’s now a strategic driver of business growth and productivity, competitive advantage, customer experience and revenue generation. But strategic IT and day-to-day IT operations are very different. Expecting one person to balance the task of both “keeping the lights on” and “transforming the business” is asking them to divide their focus in ways that aren’t realistic. When IT becomes strategic, it requires:

• Project planning
• Resource allocation
• Budget forecasting
• Security roadmaps
• Technology adoption strategies
• Vendor governance
• Data management frameworks

These tasks often fall by the wayside when a solo IT manager is drowning in urgent support tickets.

What Small Businesses Should Consider Instead

Small and mid-sized businesses don’t necessarily need a full in-house IT team — but they do need more than a single point of failure. The most effective model for SMBs today tends to be a co-managed services approach, combining internal staff with external support. 

1. A Small Internal Team or Key In-House Role

Even one dedicated employee can be valuable for:

• Managing end users
• Overseeing daily operations
• Understanding business-specific workflows
• Coordinating with leadership

But that person shouldn’t be responsible for everything. 

2. Managed Service Providers (MSPs) or Co-Managed IT

Working with an MSP can offload critical but time-consuming responsibilities such as:

• 24/7 monitoring
• Patch management
• Cloud oversight
• Backup and disaster recovery
• Cybersecurity services
• Help desk overflow

This allows the in-house IT manager to focus on strategic work or overseeing daily tasks rather than constant firefighting.

3. Cybersecurity Partnerships

Because SMBs face the same threats as large enterprises, outsourcing security functions can strengthen risk posture without hiring a full security operations team.

Services can include:

• Managed SIEM
• Managed detection and response
• Vulnerability management
• Incident response planning
• Compliance support

Many managed services providers can offer these types of niche services or a full package depending on the business needs.

4. Documentation and Knowledge Sharing

No matter the model, businesses must ensure:

• All systems are documented
• Credentials and configurations are tracked
• Processes are standardized

This reduces organizational risk and supports continuity.

Wrapping Up

The solo IT manager model may have worked in the past when technology environments were simpler and cyber risks were lower. Unfortunately that strategy is just not feasible in today’s IT landscape. IT now requires a team approach — whether internal, outsourced, or a blend of both. Small businesses that recognize this shift can improve uptime and strengthen cybersecurity,while reducing burnout and better supporting their employees and customers.

Holding onto the myth of the solo IT manager may feel cost-effective, but in reality, it’s the opposite. It introduces risk, slows innovation, and places an unfair burden on talented IT professionals who want to help the business grow — but can’t do it alone.
