What is a Firewall?
Firewalls function as a defensive wall placed between the external threats such as hackers, malware etc. and your internal network. Kind of network that allows or not packets from entering the network according to its predefined security rules. Consider it as a bouncer, permitting good traffic within, and forbidding potential threats. Cyber risks that could compromise a business network and expose it to data loss, operational downtime or even financial loss.
Why Your Business Needs a Firewall
- Network Security: A firewall is there to protect your network from unauthorized access by monitoring all incoming and outcoming data packets.
- Data Protection: It protects sensitive information which includes customer details, financial statements, and intellectual property from cybercrooks.

Types of Firewalls
Selecting the right kind of firewall for your enterprise is crucial to achieve complete security onto it. Firewall TypesThis is in form of any but not limited to these :
1. Packet-Filtering Firewalls:
It is the most simple type of firewalls. It analyzes data packets and sorts them by defined security system rules. After the inspection the problem is that it is not able to determine if this traffic is a legitimate one or some threat.
2. Stateful Inspection Firewalls:
Stateful firewalls are more developed as compared to the packet-filtering firewalls, and they monitor the connection state when an active exchange of traffic is happening between a system and another. They give a more improved security from analysing whole data packets and its state.
3. Proxy Firewalls:
Proxy firewalls serve as gateways between users and the internet, managing network traffic at an application level. Content filtering is another service they can offer to censor websites that may be damaging to users.
4. Next-Generation Firewalls (NGFW) :
In addition to the standard functions of old firewalls, new functions have been added such as those for intrusion detection, application awareness and threat intelligence in NGFWs. Perfect for businesses needing all-around security.
How Firewalls Protect Your Business Network
Firewalls do many things to guard your network. They do this in such a myriad of ways, here are some of their key ways:
1. Monitoring and Blocking Suspicious Traffic
On the other hand, a firewall is designed to detect/monitor the traffic entering and leaving your network. It employs a collection of security rules to identify and stop threats within your network before they can reach your system.
2. Protecting Against DDoS Attacks
A Distributed Denial of Service (DDoS) attack wants to bring down your network by flooding it with more traffic than it can handle. Firewalls can help reduce the impact of DDoS attacks as the traffic streams are filtered and controlled, so your system can handle designed traffics.
3. Creating a Secure VPN:
In effect it acts like a Virtual Private Network (VPN) for employees from anywhere. By encrypting data, VPNs makes sure sensitive business information cannot be accessed by everyone even when using it while on the go.
4. Stopping Internal Threats
Threats from inside your environment can be as dangerous the ones on the outside, which is why firewalls are for both. They can also provide protection from in-house employees of the organization and prohibit access to areas of the network where they do not belong, prevent any possible internal attacks or lose of information due to an accident.
Best Practices for Firewall Management

2. Performance Analysis

3. Set Specific Rules
You can create a firewall based on your business requirements via the settings. As in other tools, creating a filter specifically allows to set the rules you need to refine your protection and block all traffic that e.g. may somehow endanger our network.
4. Regular Audits
Perform routine firewall audits to ensure all settings support your security policies. That way, you can catch the potential vulnerabilities before they turn into actual threats.
