AI for Zero-Day Attack Detection

Detect zero-days with AI-powered behavioral analytics, anomaly detection, and sandboxing that surface novel threats with clear evidence.

Zero-days exploit unknown vulnerabilities, often using novel payloads and living-off-the-land techniques. AI detects them by modeling normal behavior and spotting deviations across endpoints, network, identity, and cloud. Sandboxing and deception add observable behaviors for higher confidence. Explainability and safety guard against disruptive false positives.

Alerts with evidence (process, network, sandbox), risk scores, recomme

Feedback loops, drift monitoring, red-teaming, and staged rollout of high-sensitivity detections.

Detect exploit chains, LOLBins, memory injection, privilege escalation.

Normalize events, enrich with asset/user context, and store sandbox artifacts. Integrate with EDR/NDR/SIEM/SOAR for actions and timelines.

RBAC, encryption, and retention controls for telemetry and artifacts.

Frequently asked questions

What is the role of evidence, audit trails, and change control in detecting zero-day attacks?

Evidence, audit trails, and change control for detections.

How can we measure the effectiveness of containment strategies and identify areas for improvement?

Track containment success, rollback rates, analyst validation, and red-team results.

What happens when a behavioral anomaly detects a memory-only exploit that traditional signature-based detection misses?

Behavioral anomaly caught a memory-only exploit missed by signatures.

How do sequence and entropy features help identify covert communication channels like DNS C2?

Sequence and entropy features flagged covert DNS C2, enabling quick block.
