Network security protects your entire attack surface

Network Security, Defined and Explained

Organizations and branches need both high-performance networks and strong security. Fortinet’s Network Security Solution is an integral component of the Fortinet Security Fabric that enables complete visibility and provides automated threat protection across the entire attack surface.

Powered by a single operating system it delivers industry-leading security, unmatched performance, Network security refers to the technologies, processes, and policies used to defend any network, network traffic, and network-accessible assets from cyberattacks, unauthorized access, and data loss. Every organization, from small businesses to the largest enterprises and service providers, in every industry requires network security to protect critical assets and infrastructure from a rapidly expanding attack surface. Network security must protect at the many edges of the network and also inside the network, with a layered approach. Vulnerabilities exist everywhere, from devices and data paths to applications and users. Because organizations encounter so many potential threats, there are also hundreds of network security management tools intended to address individual threats or exploits or assist with other mission-critical infrastructure needs, such as continuous compliance. Organizations should prioritize network security solutions that cover the multitude of threats, using a platform approach that prioritizes integration and automation.and reduces complexity.

Network Security, Defined and Explained

Fortinet’s Security-driven Networking strategy tightly integrates an organization’s network infrastructure and security architecture, enabling the network to scale and change without compromising security. This next generation approach is essential for effectively defending today’s highly dynamic environments – not only by providing consistent enforcement across today’s highly flexible perimeters, but by also weaving security deep into the network itself.

The Importance of Network Security

Today’s threat environment is always changing, and from distributed denial-of-service (DDoS) attacks to ransomware, the frequency, volume, and sophistication of cyberattacks show no signs of slowing down. All organizations require network security because even a minor disruption to network infrastructure—such as a minute of downtime, or a lag in service performance—can cause damage to an organization’s reputation, bottom line, or even long-term viability. Catastrophic cyberattacks, which often begin as seemingly benign intrusions that inadequate network security tools failed to catch, can force organizations to pay crippling fines and even close their doors for good.

Types of Network Security Solutions, Devices, and Tools

A very critical component of network security is a next-generation firewall (NGFW). But to truly protect the network, other technologies are required, and effective network security requires a holistic approach that integrates the firewall with other important capabilities. Essentially, to protect an organization’s entire attack surface, a layered approach with security solutions for all areas of the network must work together as an integrated and collaborative security fabric.

Network Security

Next-Generation Firewall
Traditional firewalls have been around for decades, and are a standard security product in use by a majority of organizations. But as the threat landscape has evolved, so too has firewall technology. A next-generation firewall (NGFW) moves beyond a traditional firewall’s port/protocol inspection and blocking techniques to add application-level inspection, intrusion prevention, and intelligence from sources outside the firewall.
Security Subscription Services
Protect Your Organization from the Constantly Evolving Threat Landscape

FortiGuard Security Subscriptions refer to the different security options you can choose to add on to your Fortinet devices. FortiGuard Security Subscriptions can help customer stop in-flight threats, eliminate attacks from common entry points, proactively prevent and detect breaches, and secure their expanded attack surfaces. FortiGuard Labs, the threat intelligence and research organization at Fortinet, provides the security updates to the detections and prevention capabilities to these security add-ons.

WAN Edge

SD-WAN
SD-WAN solutions enable digital transformation for organizations by leveraging corporate WAN to a deliver better application experience, reduce costs, and simplify operations at the WAN edge. SD-WAN enables deep application identification, including encrypted traffic and dynamic multi-path steering across hybrid connectivity options—MPLS, LTE 4G/5G, or broadband—ensuring organizations can quickly and easily access business-critical applications.
LTE

The number of connected devices organizations need to manage is growing rapidly, and new technologies such as SD-WAN and 5G are transforming the way businesses operate. Establishing and maintaining internet connectivity across an increasingly distributed environment is critical for business execution and competitiveness, but it can be a challenge for conventional networking approaches. These challenges include:

  • Networks are sprawling and the number of connected devices is growing
  • Continuous connectivity is critical for business continuity and competitiveness
  • Cable/DSL also offers less than 99.999% uptime—and it can’t be deployed everywhere
  • MPLS networks are costly and not scalable for current business needs

Cloud Edge

Secure Access Service Edge (SASE)
With networks expanding beyond the WAN edge to thin branch networks and the cloud, traditional hub and spoke infrastructure models centered around the corporate data center begin to break down. A new networking and security strategy is required that combines network and security functions with WAN capabilities to support the dynamic, secure internet access for a “work from anywhere” workforce. That strategy is Secure Access Service Edge, or SASE.

SASE extends networking and security capabilities beyond where they have typically been available, allowing users, regardless of location, to take advantage of firewall-as-a-service (FWaaS), secure web gateway (SWG), zero-trust network access (ZTNA), and a medley of other threat detection functions.

LAN Edge

Switching
Legacy Ethernet LANs face many challenges including exponential growth in devices and applications, increased throughput demands from wireless LANs, and complex security implementations. Rather than asking how to secure traditional Ethernet LANs, Fortinet takes a security driven networking approach offering Ethernet as an extension of the security infrastructure through FortiSwitch and FortiLink. Further in the most recent release of FortiOS 6.4 base NAC functionality is included with no additional licensing. FortiSwitch offers a broad portfolio of secure, simple, and scalable Ethernet switches ideal for Secure SD-Branch and applications ranging from desktop to data center.
Wireless
The most common form of access at the LAN Edge for users these days is Wi-Fi. Wireless Access Points can be added to any network to provide Wi-Fi access to employees and guests alike. The challenges of adding wireless to a deployment go far beyond the physical installation of the hardware.

Network IT demands more capability and reliable security from fewer components to save on cost and simplify the environment. Fortinet’s Wireless LAN equipment leverages Security-driven Networking to provide secure wireless access for the enterprise LAN edge.

Perfect for deployments from the campus to the SD-Branch, FortiAPs are Fortinet Security Fabric enabled, providing the broad visibility, automated protection, and integrated threat intelligence required to protect the valuable assets and data of organizations worldwide.
