A Network Security Firewall manages network traffic by preventing threats from entering through other networks. APTs, zero-day threats, command and control servers, botnets, and other threats are some of the main dangers that network security firewalls guard against, which helps to improve network security. Consequently, network firewall security will aid in preventing user access by unauthorised parties. The scenario of company needs has altered as a result of growing adoption of Big Data, IoT, cloud computing, and other technologies. This is done to encourage maximum agility to attain competitiveness. As a result, worries about data breaches, account theft, unauthorised access, and other issues have grown. Consequently, network security is a top concern for businesses in order to reduce problems with data security. Additionally, Network Security Firewall aids businesses in safeguarding crucial applications so that staff members can focus on their work without having to deal with server outages, email outages, or data loss, which increases productivity. Organizations must protect their data as it is accessible virtually. In-house data centres are a more secure place for data than virtual cloud networks. Therefore, one of the main barriers preventing enterprises from adopting cloud computing is data security. Consequently, cloud-based firewalls are crucial for protecting the data stored in the cloud. Email security, online filtering, network traffic management, and other functions are offered by cloud-based Network Security Firewall. Since their data is accessible over the cloud network, organisations in sectors including retail, BFSI, and government will increasingly employ cloud-based solutions. To protect their corporate networks and sensitive data from cyberattacks, this is anticipated to increase demand for cloud-based security solutions. Increased use of cloud-based web and email services by businesses that need to secure their applications from sophisticated threats like ransomware, APTs, zero-day attacks, malware, and illegal access is another factor contributing to the rise of the cloud-based market. Services Provided by Network Security Firewall-
Nearly every medium-sized and large-sized business has a website and a network of other businesses that are linked to it. Network Security Firewall depends on network partitioning at the point where the internal network and the outside Internet meet. It is common to refer to the internal network (intranet) as the "trusted" side and the external Internet as the "untrusted" side. A firewall is a type of network device that separates an organization's internal network from the Internet and other external networks. To prevent illegal access to or from the internal network, a hardware, software, or combination system may be used. Every data packet that enters or leaves the internal network must travel through the Network Security Firewall, which inspects each one and rejects those that do not adhere to the set security requirements.
