The short answer is that we need continuous protection against evolving and complex continuous cyberattacks.
Cyberattacks and attackers are evolving FAST and therefore it really comes down to answering two critically important questions:
A simple answer is to reduce risks at all layers of infrastructure, systems, policies, and people. A firewall is an important layer of security that significantly reduces the risk of network, data and resource access from outside.
A traditional modern router comes with a simple firewall that is unable to continuously protect a network for one simple reason: unlike a Firewall device basic routers do not come with continuously updated security services. Just like an advanced anti-virus program firewall security services are updated around the clock to cope with new threads.
In addition, a firewall that comes with a router does not provide the level of control and customization that is available in a firewall.
Router-based firewalls are typically built into routers and are designed to provide basic security features but may not provide as much control or customization as a firewall appliance.
Firewall appliances are standalone devices that are specifically designed to provide advanced security features for networks of all sizes. They can be more complex to set up and manage than router-based firewalls, but they offer more control and customization options. For example, they often provide more granular control over network traffic, advanced threat protection, and the ability to integrate with other security solutions.
Here are the Key Benefits:
Next-generation firewalls (NGFWs) provide advanced features and capabilities that traditional firewalls do not have. Some key benefits of deploying a next-gen firewall include:
