A firewall can either be software-based or hardware-based and is used to help keep a network secure. Its primary objective is to control the incoming and outgoing network traffic by analyzing the data packets and determining whether it should be allowed through or not, based on a predetermined rule set. A network’s firewall builds a bridge between the internal network or computer it protects, upon securing that the other network is secure and trusted, usually an external (inter)network, such as the Internet, that is not assumed to be secure and trusted.
Many personal computer operating systems include software-based firewalls to protect against threats from the public Internet. Many routers that pass data between networks contain firewall components and, conversely, many firewalls can perform basic routing functions
Palo Alto Networks, Inc. has pioneered the next generation of network security with an innovative platform that allows you to secure your network and safely enable an increasingly complex and rapidly growing number of applications. At the core of this platform is the next-generation firewall, which delivers visibility and control over applications, users, and content within the firewall using a highly optimised hardware and software architecture.
Palo Alto Networks® next-generation firewalls detect known and unknown threats, including in encrypted traffic, using intelligence generated across many thousands of customer deployments. That means they reduce risks and prevent a broad range of attacks. For example, they enable users to access data and applications based on business requirements as well as stop credential theft and an attacker’s ability to use stolen credentials.
As security architects consider how to provide comprehensive threat protection for their enterprises, including intrusion prevention, web filtering, anti-malware and application control, they face a major complexity hurdle managing these point products with no integration and lack of visibility. Gartner estimates that by 2019 80% of enterprise traffic will be encrypted and 50% of attacks targeting enterprise will be hidden in encrypted traffic.
FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance including encrypted traffic. FortiGate reduces complexity with automated visibility into applications, users and network and provides security ratings to adopt security best practices.
FortiGate enterprise firewalls offer flexible deployments from the network edge to the core, data center, internal segment, and the Cloud. FortiGate enterprise firewalls leverages purpose-built security processors (SPUs) that delivers scalable performance of advanced security services like Threat Protection, SSL inspection, and ultra-low latency for protecting internal segments and mission critical environments.
FortiGate NGFW provides automated visibility into cloud applications, IoT devices and automatically discovers end to end topology view of the enterprise network. FortiGate is a core part of security fabric and validated security protect the enterprise network from known and unknown attacks.
