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.
TI products and services deliver knowledge, information and data about cybersecurity threats and other organization-specific threat exposures, including but not limited to indicators of compromise (IOCs), threat actor attribution and campaigns. The output of these products and services aim 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 risk and the chance of being compromised.
