The Top 5 Reasons Why Your Business Needs a Strong Firewall


In this age of global connectivity, protecting your business's assets and data is more important than ever. Almost all businesses are connected to the Internet for a wide variety of services. These include email, search, social media, and cloud storage. While much of this traffic is outbound, the fact is that the same Internet connection also allows inbound traffic. That is where having a strong hardware- or software-based firewall comes into play. You can use it to protect your business network from unauthorised access.

Here are the top five reasons why your business needs a strong firewall:

1. A Firewall Is Your First Line of Defence against Hackers and Other Unauthorised External Users

A firewall acts as a barrier, or shield, between your internal business network and the rest of the Internet. Without a firewall, it is possible for external users to access your private business assets. While many organisations use Network Address Translation (NAT) to bridge Internet and external IP addresses, NAT will not block incoming traffic. Only a firewall can do that. Without a firewall, your organisation's assets and data are at risk.

2. A Firewall Lets You Block Access to Unapproved Websites

In addition to stopping unauthorised external users from accessing your network, a firewall can stop your users from accessing specific external websites. For instance, you could set up a policy that blocks access to social media sites like Facebook from your network.

3. A Firewall Can Protect Your Business from Malicious Code

Some strong firewalls will inspect the traffic going into and out of your network. They look for and block viruses, worms, spam, and other unwanted Internet traffic. They will also log intrusion attempts as well as other violations to business policies. This enables you to examine unauthorised access attempts and other suspicious activity.

Many of these strong firewalls will also let you maintain a list of known malicious applications and known good applications. They will block the malicious applications, while enabling the good ones.

4. You Can Use a Firewall to Meter Bandwidth

A firewall can do more than just provide security. You can also use it to meter and limit the network bandwidth flowing through it. For example, you can limit the network bandwidth allowed for things like non-business videos, music, and images, thereby reserving bandwidth for higher priority business traffic.

5. You Can Use a Firewall to Provide VPN Services

Many firewalls provide site-to-site connectivity through Virtual Private Network (VPN) services. Through this VPN functionality, mobile device users and users at remote sites can securely access your internal network resources. This enhances productivity, collaboration, and data sharing.
