AI Threat Detection
The use of machine learning models to detect security threats — anomalous access patterns, exfiltration precursors, novel attack techniques — in real time.
Full Definition
AI threat detection applies supervised and unsupervised learning to security telemetry: identity events, network traffic, endpoint behaviour, cloud API calls, data-access patterns. Models trained on known-good baselines surface anomalies — an account suddenly reading from stores it has never touched, an API key making calls from a new country, an endpoint uploading unusual volumes to an unknown destination — faster and at wider coverage than rule-based detection can achieve alone.
For privacy specifically, AI threat detection accelerates the detection half of GDPR Articles 33-34, DPDP Rule 7 and PDPA breach obligations. Faster detection shortens the gap between compromise and discovery, which is the single largest driver of breach cost in the Ponemon annual reports. The flip side: AI threat detection models are themselves AI systems in scope of the EU AI Act's governance obligations and of the privacy framework, since the telemetry they ingest contains personal data about users and employees. The models are high-trust components and need their own data-governance, bias and explainability treatment.
