Why Is Network Security Important?

Feb 06, 2026

As the number of cyber attacks continues to rise, so does the importance of network security. According to statistics, global cybercrime damage costs are estimated at $10.8 trillion in 2026 and are projected to rise to $12.2 trillion by 2031.

But why do we need network security? 

In this blog post, we’ll take a look at the importance of network security and explore some of the key reasons why it’s essential for your business. 

Why Do We Need Network Security? 

A network attack is an unauthorized action on the digital assets within your organization’s network. Network attacks are usually carried out by malicious parties to alter, destroy, or steal your private business information. To gain access to your internal systems, attackers usually target the perimeters of networks. 

So, why do we need network security? The answer is simple: the costs of cybercrime can be devastating for businesses. As a result, according to CloudSecureTech, 60% of small businesses that suffer a cyber attack shut down within six months.

Cybercrime costs include:

• Damage and destruction of data

• Stolen money

• Lost productivity

• Theft of intellectual property

• Theft of personal and financial data

• Post-attack disruption to the normal course of business

• Forensic investigation

• Restoration and deletion of hacked data and systems

• Reputational harm

These monetary losses all demonstrate the importance of network security for your business.

Why Network Security Is Important 

1. Protection of Information 

The importance of network security lies in the fact that it prevents cybercriminals from accessing your sensitive data. 

As cyber attacks become increasingly sophisticated, your business is in greater need of advanced tools to prevent criminals from gaining unauthorized access to sensitive business information. These tools include:

• Firewalls

• Biometrics

• Encryption 

• System data back-up

• User level permissions 

Without thorough network security practices in place, your business is at serious risk of having company records, passwords, client data, and other sensitive information stolen by unethical hackers and unauthorized users. 

2. Increasing Risk of Data Breaches 

The average number of data breaches per year affecting small businesses continues to increase as more companies migrate to digital environments for shared data. 

And the biggest cybersecurity threat to organizations comes from within them. Stanford University found that employee errors, whether intentional or accidental, account for 88% of data breaches.

Through network security training, employees are equipped with the skills needed to effectively manage cyber risks in operational roles within an organization. A managed service provider (MSP) can not only safeguard the infrastructure of your network, but also train your employees in network security best practices.

Here’s how.

3. DDoS Attacks That Disrupt Your Website or Network Connection

It’s important for your business to invest in network security so that in the case of a security breach or DDoS attack, you will not be left vulnerable. A distributed denial of service (DDoS) attack is an attempt to make your business’s network unusable by flooding it with traffic from multiple sources. 

These attacks can cause your networks to slow down significantly, making them unable to handle normal tasks, resulting in huge losses for the company. 

Good network security involves maintaining secure systems and policies that are implemented regularly and tested before use. By doing this, you can rest assured that your networks are safe from DDoS attacks and other cyber threats and ensure smoother operations throughout your day-to-day activities.

Here is how DDoS attacks work.

4. Ensuring Regulatory Compliance

Network security is an important aspect of regulatory compliance because it helps safeguard confidential information and systems from malicious activities and cyber attacks. 

To maintain regulatory compliance, you must protect your corporate networks from vulnerabilities, reduce the risk of data leakage, and maintain a secure environment for conducting business transactions.

Keeping data safe by utilizing a robust type of network protection plan ensures compliance with standards set forth by governing bodies and sets a reliable foundation for keeping information secure and confidential – another reason why network security is important. 

5. Establishing Consumer Confidence 

By offering network security systems, you can give your clients the peace of mind that their most important assets – their computer systems, online networks, and data – are safe and protected from network threats with proper information security. 

Implementing stronger authentication methods such as two-factor verification and biometric recognition protects your data from theft, manipulation, or misuse by third-party entities – ensuring legitimate authorship of the information entered.

These measures go a long way towards building consumer confidence, as your clients can rest assured that their online activities are protected with proper security measures when doing business with you.

The Importance of Network Security and Finding the Right Managed Service Provider
