A building has:

Similarly, digital networks use:
- Firewalls
- Antivirus software
- Encryption

to stay protected from hackers and threats.
Whenever data travels between devices or systems, network security helps keep that information safe.

Companies store a lot of important information online:

Without proper security, this information can easily be stolen or leaked.
Prevents Cyberattacks
