Firewalls can be a central part of IT security as some maybe software firewalls such as complementing anti-virus programmes for PCs. In layman terms, firewalls are like bounces or doormen which strand at the entrance to various types of networks, computer, applications, database and other resources which they are used to restrict traffic incoming (and outgoing) traffic and determined whether to let certain data pass through the entrance or whether to reject the data from passing through the system.
But the term “firewall” is far too broad to be of much use to IT security buyers. There are many different types of firewalls, each of which works in different ways to protect different types of resources, both within data centres and corporate perimeters and outside in the cloud.
Packet-filtering network different firewalls provide essential network protection which assists with getting rid of unwanted traffic from getting into the network this could be a security breach, especially for corporate networks. They work by applying a set of network firewall security rules which allows or denies data packets. This is typically used to protect unwanted traffic from coming into the network. The typical rules are to deny entry to all traffic except for designated ports using specific protocols or specific IP addresses.
With our products, there are many operating systems that serve with our firewalls. Such as open source software such as Pfsense and other like Untangle, Sophos, Debian, Smoothwall, ClearOS, m0n0wall and many more. We also serve network firewalls such as next-generation firewalls (NGFW) such as NSHO-001 and NSHO-002 which inspects the content of packets to give administrator far greater control.
The next generation firewalls serve a greater purpose than our traditional firewalls which protects the network from unwanted data traffic, However, they work in a different way to achieve better results for larger networks and withstanding many users and traffic towards the network.
