What is a firewall?
A Firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization’s previously established security policies.
Firewall is a software program (or hardware) that protects computer networks from hacker-initiated cyber-attacks. It serves as the first line of defense in network security by efficiently monitoring traffic and preventing unauthorized access and the transmission of unwanted content.

We use the third generation of firewall technology, also known as Next Generation Firewall (NGFW) has evolved. It is capable of detecting and blocking sophisticated attacks with new-age security policy enforcement.
Firewalls serve as a first line of defence:
Monitors Network Traffic
The benefits of firewall security begin with the ability to monitor network traffic. Data entering and exiting your systems can create opportunities for threats to compromise your operations. By monitoring and analyzing network traffic, firewalls use pre-established rules and filters to keep your systems protected. With a well-trained IT team, you can adjust your levels of protection based on the traffic passing through your firewall.
Stops Virus Attacks
Nothing can disrupt your digital operations more quickly and severely than a virus attack. With hundreds of thousands of new threats emerging every day, it is crucial to establish strong defenses to maintain the health of your systems. Firewalls offer a clear advantage by allowing you to regulate your system's entry points and prevent virus attacks. The potential cost of damage from a virus attack on your systems could be incalculably high, depending on the type of virus.
Regrettably, the shift of businesses towards digital operations has attracted thieves and malicious actors. As data theft and ransomware attacks increase, firewalls play a crucial role in preventing unauthorized access to your data, emails, and systems. A firewall can effectively block hackers or discourage them from targeting your systems.
In a data-driven world, a much-needed benefit is stopping spyware from gaining access and getting into your systems. As systems become more complex and robust, the entry points criminals can use to gain access to your systems also increase. One of the most common ways unwanted people gain access is by employing spyware and malware—programs designed to infiltrate your systems, control your computers, and steal your data. Firewalls serve as an important blockade against these malicious programs.
