A business needs an information technology (IT) team, in-house or outsourced, to keep systems patched, protect data, manage access and respond fast when something goes wrong. The stakes are high: IBM’s Cost of a Data Breach Report 2026 puts the global average cost of a data breach at USD 4.99 million, a record high.
Key Takeaways
- According to IBM’s Cost of a Data Breach Report 2026, the global average breach cost USD 4.99 million, up 12% on the previous year.
- Verizon’s 2026 Data Breach Investigations Report found that 31% of breaches now start with software vulnerabilities, and 48% involve ransomware, so patching and backups are core IT work.
- An IT team does not have to be full-time staff: many small firms use a managed service provider or a hybrid model.
- Free frameworks such as NIST CSF 2.0 and CISA Cyber Essentials give any business a structure to follow.
When it comes to running a business of any kind, it has become imperative to protect yourself, your data, and your employees online. Online threats to businesses keep growing in cost and sophistication: IBM’s Cost of a Data Breach Report 2026 puts the global average cost of a breach at USD 4.99 million. Cyber attacks have increased.
Hackers, viruses, and malware have become increasingly sophisticated. It doesn’t matter whether you are in the tech industry or not, protecting your data and resources online is vital. Below are some reasons why you need an information technology (IT) team.
Prevent Attacks
In the best-case scenario, your IT team prevents any possible attacks. However, this is likely impossible. There will always be a threat to your technological infrastructure, even if you have a full IT team in place to watch for attacks and prevent them. Whether it’s by using encrypted software to organize and store data or employing better anti-malware, there are plenty of ways that your IT team prevents attacks. One way is to close the holes in your system.
Close Holes
One of the things you need is an IT team to close holes in your cybersecurity strategy. There can always be holes in cybersecurity no matter how good it is. When a team regularly looks for weaknesses in your defenses, it finds the gaps hackers could use to get into your network, devices, and servers before attackers do. Whether you are employing a team full time or are contracting professionals to give your cybersecurity strategy a boost, closing holes in the structure is a huge part of IT work.
Assess Risks
Another thing that you need to do when you are hiring an IT team is assess the risks involved. Not only will the team close holes in the security, but they can also alert you of overall risks and how to mitigate them. When it comes to risks and security issues, your IT team may not be able to solve every problem, but they can certainly let you know what to do, what to buy, and who to hire to lower those risks. Risks are inherent in any cybersecurity situation. It’s important to know what they are and what you need to do to prevent breaches and attacks.
Protect Data
Perhaps the most pivotal thing your IT team does is protect your data. Data has become one of the most valuable assets in the world. It doesn’t matter what business you’re in. Whether you are a company that uses data in your business model, or you just want to learn how to make your customers happy, protecting the data from being stolen or erased is a huge responsibility.
An IT team needs to overcome these threats and help your company protect the data that it has. The structure and organization of your data can also help protect it. It’s a lot easier when you know where everything should be. Data protection skills are in demand: the US Bureau of Labor Statistics lists a 2025 median pay of $129,180 per year for information security analysts and projects 21% job growth for 2025-35.
Respond to Breaches
Finally, one of the most important things any IT team can do is respond to breaches when they do happen. If a breach occurs, it’s all hands-on deck. A written incident response plan, with named roles and tested backups, makes that response faster and calmer. When a breach occurs, they must work overtime until they find the problem and fix it. As much as the IT team prevents breaches, they also must respond to them. The IT team should do everything in their power to respond quickly to any kind of breach. The problem might not have been the result of their actions, but it’s still their job to respond.
The tasks above are just a few reasons to make sure your IT team is competent. You might not have to hire a full team full-time, but you should make sure that you are working with some great IT professionals. These people aren’t cheap, but they will help you prevent breaches, attacks, and other security risks that could cost you a lot more money. Whether you are in the business of tech or not is irrelevant. These days, everyone needs a professional IT team to help them keep their information, data, files, devices, network, and servers safe. If you do not have dedicated IT support yet, start with the checklist below and decide whether in-house staff, a managed provider or a mix suits your business.
What Does an IT Team Do for a Business?
An IT team keeps a business’s technology working and secure. In practice that covers a predictable set of jobs:
- Patching and updates: installing security fixes on operating systems, applications and network devices. Verizon’s 2026 DBIR found software vulnerabilities are now the most common way attackers get in (31% of breaches), ahead of stolen passwords.
- Access management: creating and removing user accounts, enforcing multi-factor authentication (MFA) and giving each person only the permissions they need.
- Backups and recovery: running regular automated backups and testing that data can actually be restored, which matters because Verizon reports that 48% of breaches involve ransomware.
- Monitoring and response: watching for suspicious activity and leading the response when an incident happens.
- Help desk and planning: supporting staff, buying and configuring hardware and software, and planning upgrades.
In-House IT vs Managed IT Services
Businesses usually choose between hiring their own staff, outsourcing to a managed service provider (MSP), or combining the two. The right choice depends on size, budget and how much specialist knowledge the business needs. For a deeper comparison, see this guide to choosing in-house or outsourced IT support.
| Model | Best for | Strengths | Trade-offs |
|---|---|---|---|
| In-house IT team | Larger firms, regulated industries | Knows the business well; on site; full control | Salaries and training costs; hard to cover every specialty |
| Managed service provider | Small and mid-sized businesses | Access to a wider skill set; predictable contract | Less day-to-day presence; depends on contract terms |
| Hybrid | Growing businesses | Internal staff for daily needs, specialists for security or projects | Requires a clear division of responsibilities |
Hiring is competitive. The US Bureau of Labor Statistics counted 192,900 information security analyst jobs in 2025 and says the typical entry-level education is a bachelor’s degree. Readers considering the career can read how to get a job in information security.
Which Frameworks Can an IT Team Follow?
The NIST Cybersecurity Framework (CSF) 2.0, released by the US National Institute of Standards and Technology on February 26, 2024, organizes security work into six functions: Govern, Identify, Protect, Detect, Respond and Recover. NIST says CSF 2.0 is designed for all audiences and organization types, from the smallest schools and nonprofits to the largest agencies and corporations.
CISA Cyber Essentials, from the US Cybersecurity and Infrastructure Security Agency, is written for leaders of small businesses and of small and local government agencies. It groups its advice into six elements: Yourself, Your Staff, Your Systems, Your Surroundings, Your Data and Your Crisis Response.
A Starter Security Checklist for Small Businesses
CISA highlights three immediate actions for small organizations: back up data, implement multi-factor authentication and enable patch management. A practical first list for any IT team or provider:
- Turn on MFA for email, banking, cloud storage and admin accounts.
- Enable automatic updates and keep an inventory of devices and software so nothing is missed.
- Run automated backups, keep a copy separate from the main network, and test a restore. This guide explains why cloud backup and recovery matter.
- Use long, unique passwords stored in a password manager; the secure password generator creates random ones in the browser.
- Train staff to spot phishing, following steps such as those in protecting employees from spear phishing.
- Write an incident response plan with named roles and contact details, and rehearse it.
Does AI Change What an IT Team Does?
AI tools are now part of both attack and defense. Verizon’s 2026 DBIR reports that 15% of different attack techniques are now being bolstered by generative AI. On the defensive side, IBM’s 2026 report estimates cost savings of USD 1.93 million from extensive use of AI and automation in security, compared with organizations using none. An IT team decides which of these tools to adopt and keeps them configured correctly.
Frequently Asked Questions
