Network security is a set of actionable measures organizations take to prevent accidental damage to sensitive network data. Poor security practices within an organization lead to the exposure of private data, including customer data. In addition, hackers are continuously looking for new vulnerabilities to exploit business networks and access data. The old security tools are not as effective in protecting the network and require specialized network security software to do the job. 

Network security software protects the network infrastructure from unauthorized access, misuse, and theft. It also helps keep sensitive data safe from cyber-attacks, ensures that the company meets regulatory compliance requirements, and avoids legal troubles. 

This guide covers the best network security software available in the market with its key features. Go through it and decide which one suits you the best. 

Why Do Businesses Need Network Security?

With the increasing use of technology, businesses rely more on their networks for data storage, communication, application usage, and other activities that malicious actors can compromise if not appropriately protected. In addition, securing business networks becomes even more crucial as the number and cost of data breaches and cyber crimes are increasing. The average cost of a data breach is $4.24 million, which further increases the demand for robust network security. 

Network security has become a vital aspect of all businesses. It helps organizations prevent data breaches that result in millions of lost revenue. Besides this, it ensures that sensitive customer data or financial information is not shared with unauthorized persons. Cybercriminals can sell this information on the dark web, use it for identity theft, or launch other cyber attacks. 

There are different components used to secure a network. This includes VPNs, firewalls, antivirus software, EDR, XDR, and more. All these components mix with the network security practices to secure the network from malware, spyware, ransomware, and other intrusions through accidental or intentional means. 

A reliable network protects organizational interests and operations and clients who exchange information with them and trust them to share their sensitive data. Here’s a reminder of the top benefits your business gain from having strong network security:

  • Builds trusts
  • Mitigate risks
  • Comply with regulatory compliance in your industry
  • Enables a modern workplace

As a whole, organizations must consider network security as it protects them from internal and external threats. By implementing network security protocols and practices, businesses can ensure that their systems are safe and can focus more on their business goals.
