David Sandin, product manager of Clavister shows how new approaches to delivering next-generation security can benefit your business.

The firewall has been the first line of cyber defence for companies for the past 20 years. Firewalls used to be relatively simple devices – in effect, a border control on your network that allows or denies access to certain types of traffic, based on the resources the traffic is trying to access. For example, can a remote user connect to the email server, yes or no?

However, threats to networks have evolved from this simple scenario, which means that network defences have had to evolve, too. Enter next-generation firewalls (NGFWs). In addition to allowing or denying network connections, they deliver better, faster and more intelligent security than conventional firewalls, to support the more complex traffic generated by use of web applications.

Next-generation firewalls (NGFWs) deliver better, faster and more intelligent security than conventional firewalls, to support the more complex traffic generated by use of web applications.

They inspect the content of network traffic, looking for malware and other threats, blocking stealthy intrusion attempts, and controlling the types of web application available to specific users. For example, can someone in the accounts team connect to Youtube, yes or no? NGFWs effectively add X-ray scanning and advanced detection technology to a border control, making defences more advanced and better able to secure modern networks against current and emerging stealthy threats. And these threats are both real, and costly.
