Firewalls are an essential part of cybersecurity for small businesses. They protect networks by monitoring internet traffic, blocking cyber threats, and preventing unauthorised access to business systems. Small businesses are often targeted by cybercriminals because they may have fewer security resources than larger organisations. A reliable firewall helps protect sensitive information, supports secure online activities, and reduces the risk of costly cyberattacks. This guide explains why firewalls are important for small businesses and how they improve network security.
