Managed Network Services vs. DIY: What Actually Works for SMB Security?

Small and medium-sized businesses (SMBs) are increasingly reliant on their IT infrastructure to operate smoothly. Yet, with rising cybersecurity threats and complex regulations, a pressing question emerges: Should you hire a managed network services team or build an in-house DIY setup?

Both approaches have benefits, but when it comes to security and efficiency, one stands out as the better option for most SMBs. Let’s explore the pros and cons and why security penetration testing is vital regardless of which path you pick.

1. Understanding the Options: Managed Services vs. DIY

What are Managed Network Services?

Managed network services involve outsourcing your company’s IT needs to an external team. These professionals monitor, maintain, and secure your network on an ongoing basis. They implement best practices, keep hardware and software updated, and respond quickly to potential threats.

What is a DIY In‑House Setup?

DIY means relying on an internal team—or sometimes just one person—to build and maintain your network. This approach gives you direct control and can save money upfront, but it also means you’re responsible for all upkeep, monitoring, and security.

1. Cost Considerations

For many SMBs, cost is the first consideration. An in‑house approach may seem less expensive because it doesn’t involve paying external service fees. However, the long‑term costs can quickly add up. Maintaining equipment, training staff, and responding to cyber incidents can lead to unexpected expenses.

On the other hand, managed network services operate on a predictable subscription model. You pay a fixed fee for a team of professionals with access to advanced tools and expertise, making budgeting straightforward. In many cases, this approach delivers a higher return on investment for SMBs.

1. Expertise and Scalability

Cybersecurity and network maintenance require highly specialised knowledge. An in‑house team may struggle to keep up with the latest threat vectors, new technologies, and best practices unless you’re prepared to hire dedicated cybersecurity staff.

Meanwhile, managed network services providers (MSPs) have access to deep expertise across disciplines and are able to scale services to match your growing business needs.

For example, if your company suddenly needs to secure a larger network due to a new office location or an expanded online presence, an MSP can accommodate that quickly. An in‑house team might require significant hiring and training efforts, making the process slower and more costly.

1. Compliance and Regulations

Depending on your industry, compliance with regulations can be challenging. An MSP often has experience aligning networks with these regulations and can help minimise the risk of costly penalties.

An in‑house approach may work for smaller businesses with less stringent compliance requirements, but for those subject to regular audits, the expertise of a managed network services team can be a significant advantage.

1. The Importance of Proactive Monitoring

Cyber threats evolve daily, making proactive monitoring vital. In‑house teams may lack the tools or staff required for 24/7 monitoring. An MSP typically operates a Network Operations Centre (NOC) that constantly monitors traffic, identifies anomalies, and applies patches and updates as needed.

With managed network services, threats can be neutralised before they cause damage. In a DIY setup, detection often occurs after the fact, when significant damage has already been done.

1. The Role of Security Penetration Testing

Regardless of the approach you choose, one critical component of any cybersecurity strategy is penetration testing. This process involves simulating cyberattacks to assess the resilience of your network. It identifies vulnerabilities in both the technology and human elements of your organisation.

For SMBs relying on in‑house setups, penetration testing can pinpoint areas where internal staff may need training or where hardware and software require strengthening. In the managed network services realm, penetration testing serves as an ongoing quality measure, ensuring that the service provider delivers on its promise of robust protection.

In both cases, regular testing provides actionable data that improves security, making it an essential investment regardless of your approach.

1. So, What Works for SMB Security?

For smaller businesses with basic needs and some internal expertise, a DIY approach can work, at least initially. However, as your company grows and your exposure to cyber threats increases, relying solely on in‑house staff can quickly become a risk.

Most SMBs benefit from working with a trusted managed network services partner. The predictable pricing, access to expertise, 24/7 monitoring, and scalability offered by MSPs provide significant benefits. Importantly, adding penetration testing to the mix ensures that your security measures evolve with your business and its threat landscape.

Final Thoughts

In the end, the right choice depends on your business’s size, resources, and risk tolerance. However, in an environment where cybersecurity threats evolve by the minute, partnering with a managed network services team and conducting regular penetration testing can save money, protect your reputation, and enable you to focus on growing your business.
