Extended detection and response (XDR) delivers security incident detection and automated response capabilities for security infrastructure. XDR integrates threat intelligence and telemetry data from multiple sources with security analytics to provide contextualization and correlation of security alerts. XDR must include native sensors, and can be delivered on-premises or as a SaaS offering. Typically, it is deployed by organizations with smaller security teams.
SIEM is a configurable security system of record that aggregates and analyzes security event data from on-premises and cloud environments. SIEM assists with response actions to mitigate issues that cause harm to the organization and satisfy compliance and reporting requirements. 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. Identifying and investigating security events of interest 3. Supporting manual and automated response actions 4. Maintaining and reporting on current and historical security events
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.”
