What is a firewall?

A firewall is an element of network security designed to act as a gatekeeper for incoming and outgoing traffic, allowing safe traffic through and stopping potentially unsafe connections, based on a set of pre-set security policies.

 

Is a firewall also an antivirus?

They are two separate security solutions, with firewall responsible for protecting the network at the protocol level, and the antivirus offering protection for internal software

 

Does a firewall stop viruses?

No! While the firewall can protect you from receiving connections from an untrusted sources, and filter all connections for risk, antivirus is still responsible for protecting your system from viruses. The more cutting-edge firewalls, like Sangfor’s Next Generation Application Firewall (NGAF), can be integrated with an array of additional security devices, offering protection from viruses.

 

Does a firewall stop ransomware?

Firewall can help protect your network, but firewall alone can’t guarantee protection from ransomware. Although, if you have the NGFW like Sangfor’s Next Generation Application Firewall (NGAF), that can be integrated with an array of additional security devices, offering protection from ransomware.

 

Do I need a firewall if I have a VPN?

VPN and Firewall both serve different purpose. VPN help to hide data from other guy's monitoring and Firewall help to avoid other guys illegally access your data/device. If both – Firewall and VPN are configured correctly, then they function very well in unison that offer amalgamated strengths, and functions.

 

Is a firewall a router?

There are both hardware firewalls, like a router, or software firewalls, each providing unique benefits. If configured correctly, the firewall and router working together will provide added security protection.

 

Does a firewall detect threats to my network?

If a malicious packet does try to enter your network, your firewall will ideally detect that threat and disallow it access to the network. Older firewall has becoming increasingly unreliable at threat detection, but newer Next Generation firewalls have proven themselves up to the challenge.

 

Do firewalls block any essential traffic?

There is always the chance of a firewall blocking access to essential traffic – but only if it’s malfunctioning or if security policies have been set incorrectly. This is where simple operation and maintenance come in. Pop-ups, alerts and automatic policy reviews are just a few functions available with newer firewall technology, like NGAF.
