Proper firewall configuration is also essential, as default features may not provide maximum protection against cyberattacks.Īs the digital landscape grows more complex due to more devices, users, and applications crossing through the network perimeters – especially due to the growing volume of IoT and end user devices – and less overall centralized control from IT and security teams, companies are becoming much more vulnerable to cyberattacks. As part of the first line of defense against cyberattacks, firewalls offer essential monitoring and filtering of all traffic, including outgoing traffic, application-layer traffic, online transactions, communications and connectivity- such as IPSec or SSL VPN- and dynamic workflows. While an advanced firewall can no longer single-handedly defend a network against today’s complex cyber threat landscape, these devices are still considered to be the foundational building block for creating a proper cybersecurity system. Without firewalls, computers and devices in your network are susceptible to h ackers and make you an easy target for attacks.

This prevents unauthorized users, devices, and applications from entering a protected network environment or segment. These rules can also prevent users within the network from accessing certain sites and programs.įirewalls are based on the simple idea that network traffic from less secure environments should be authenticated and inspected before moving to a more secure environment. Firewalls block incoming malware based on a set of pre-programmed rules. A firewall is a network security solution that protects your network from unwanted traffic.
