IT Security refers to products and services that protect digital systems and data from cyber threats and unauthorized access. This category includes markets that focus on network security, identity management, data protection, and cloud security, enabling organizations to reduce risk, ensure compliance, and operate securely in a digital world.
Gartner defines the network firewall market as the market for firewalls that use bidirectional stateful traffic inspection (for both egress and ingress) to secure networks. Network firewalls are enforced through hardware, virtual appliances and cloud-native controls. Network firewalls are used to secure networks. These can be on-premises, hybrid (on-premises and cloud), public cloud or private cloud networks. Network firewall products support different deployment use cases, such as for perimeters, midsize enterprises, data centers, clouds, cloud-native and distributed offices.
