Real-Time Inference for Cybersecurity
Quick Definition
Generating ML predictions on-demand as requests arrive, typically with latency requirements under 200ms for user-facing features.
Full glossary entry →Cyber threats operate at machine speed—ransomware encrypts files in seconds, account takeovers happen in milliseconds, network intrusions propagate faster than human reaction time allows. Real-time ML inference is the only way to detect and block threats as they happen rather than discovering them in log review hours later. Sub-100ms inference latency is a hard requirement for effective prevention, not just detection.
How Cybersecurity Uses Real-Time Inference
Network Intrusion Detection
Score every network packet or flow against a trained anomaly detection model in real time, flagging deviations from baseline behaviour for immediate SOC investigation.
Account Takeover Prevention
Score every login attempt against a real-time risk model incorporating device fingerprint, IP reputation, behavioural biometrics, and session history within 50ms of authentication.
Malware Classification at the Endpoint
Run on-device ML inference to classify unknown file behaviour as malicious or benign before execution completes, without requiring a cloud roundtrip.
Tools for Real-Time Inference in Cybersecurity
NVIDIA Triton Inference Server
High-throughput, low-latency model serving at the network edge for security models where every millisecond of latency matters.
Apache Kafka
High-throughput event streaming backbone for routing security events to inference endpoints and action systems in real time.
AWS SageMaker Endpoints
Autoscaling real-time inference for cloud-based security scoring that handles traffic spikes during active incidents.
