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.
The security threat intelligence products and services market refers to the combination of products and services that deliver knowledge (context, mechanisms, indicators, implications and action-oriented advice), information and data about cybersecurity threats, threat actors and other cybersecurity-related issues. The output of these products and services aims to provide or assist in the curation of information about the identities, motivations, characteristics and methods of threats, commonly referred to as tactics, techniques and procedures (TTPs). The intent is to enable better decision making and improve security technology capabilities to reduce the likelihood and impact of a potential compromise. Threat intelligence (TI) products and services support the different stages of a TI process life cycle. In particular, this involves defining the aims and objectives, collecting and processing intelligence originating from various sources, analyzing and disseminating it to different stakeholders within the organization, and regularly providing feedback on the entire process. These products and services support ongoing security investigations and assist in preventing future breaches by prioritizing infrastructure hardening. TI tools and services are most commonly cloud-based products and services, but can also be delivered “as a service.”
