A hybrid mesh firewall (HMF) is a multideployment mode firewall, including hardware, virtual appliance and cloud-based options, with a unified cloud-based management plane. HMF’s are designed to support hybrid environments and evolving use cases by offering mature continuous integration/continuous delivery (CI/CD) pipeline integration, native cloud integration, and advanced threat prevention capabilities extending to Internet of Things (IoT) devices and DNS-based attacks. With the adoption of hybrid environments, clients prefer the same firewall vendor with centralized management and visibility of firewall policies across environments to ease administration and reduce operational complexity. As a result, the demand and adoption of cloud firewalls from the same on-premises firewall vendor is growing. Hybrid mesh firewalls support this use case through hardware, virtual and dedicated cloud firewall deployment types, along with cloud-based centralized visibility and management capability.
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.
The network intrusion detection and prevention system (IDPS) appliance market is composed of stand-alone physical and virtual appliances that inspect defined network traffic either on-premises or in the cloud. They are often located in the network to inspect traffic that has passed through perimeter security devices, such as firewalls, secure Web gateways and secure email gateways. IDPS devices are deployed in-line and perform full-stream reassembly of network traffic. They provide detection via several methods — for example, signatures, protocol anomaly detection, behavioral monitoring or heuristics, advanced threat defense (ATD) integration, and threat intelligence (TI). When deployed in-line, IDPSs can also use various techniques to detect and block attacks that are identified with high confidence; this is one of the primary benefits of this technology. Next-generation IDPSs have evolved in response to advanced targeted threats that can evade first-generation IDPSs. (Retired as of Mar-12-2026).
Security information and event management (SIEM) is a configurable system of record that collects, aggregates and analyzes security event data from on-premises and cloud environments. SIEM processes security event data for the purposes of threat detection, investigation and response. It natively supports data normalization and offers user-configurable detection content and reporting to orchestrate threat mitigation and satisfy compliance requirements. These solutions are delivered via a SaaS platform or client-hosted on-premises or private cloud. The security information and event management (SIEM) system must assist with: 1. Aggregating and normalizing data from various IT and operational technology (OT) environments. 2. Designing and executing near real-time monitoring and alerting content. 3. Enriching and investigating security events of interest. 4. Supporting manual and automated response actions. 5. Maintaining and reporting on current and historical event data.
