There are a variety of different types of firewalls available. Packet-filtering firewalls – for example – perform simple checks of all the data that arrives from a network router, sources, destinations and other forms of surface-level data like IP addresses. Whereas a web application firewall or WAF works by blocking, filtering and monitoring data as it travels throughout websites and applications. Each firewall has different applications and benefits to suit specific business needs, so there’s no doubt there’ll be something out there for you.
do I need a firewall?
In short, yes. If your team use computers or devices that connect to the internet then you should invest in some sort of antivirus or firewall protection. Firewalls are a good solution for offices or commercial buildings because they block unwanted malware or hackers from entering the network system. Besides, firewalls are designed to provide comprehensive protection for larger networks with multiple devices, rather than – say – a single computer in a home setting.
