What is meant by Fortinet?

Fortinet’s well-known cybersecurity business focuses on creating and offering various network protection and cybersecurity solutions. The business provides a wide range of goods and services to shield people and businesses against online dangers, including malware, viruses, data leaks, and other assaults.

Fortinet’s solutions’ hardware and software components include its flagship FortiGate Firewalls, well-known for their robust threat detection and prevention skills.

Concept of Firewalls

To monitor and manage incoming and outgoing network traffic following the security regulations previously defined by an organization, firewalls are network security hardware or software solutions. They serve primarily as a firewall between trustworthy internal networks, like an organization’s intranet, and shady external networks, like the Internet. Computer systems, networks, and data must be protected against unauthorized access, cyberattacks, and other security risks via firewalls.

Firewalls inspect data packets as they pass between computers and networks. They use established rules or regulations to decide whether to let or prohibit traffic. The source or destination IP address, the port numbers, and the kind of network protocol used can all be used as bases for these rules. A network can use firewalls in various places, including on individual devices (host-based firewall), between network segments, and at the perimeter (external firewall). Firewalls are crucial to network security to prevent unauthorized access, identify and stop malicious activity, and build a security barrier to protect sensitive data and digital assets.
