The solution provides deep visibility into network communications and helps identify hidden attacks that may not be detected by traditional security tools such as IDS/IPS, antivirus, or endpoint-only protection.
Guardsix NDR uses dedicated sensors to passively monitor traffic from key network segments and operates as part of the unified Guardsix platform, enabling correlation with SIEM, SOAR, endpoint telemetry, and other security data.
Guardsix NDR capabilities ensure network security visibility and provide the ability to:
- Monitor network traffic across critical infrastructure segments without interfering with production systems;
- Detect anomalous behavior, lateral movement, command-and-control activity, and other suspicious network patterns using behavioral analytics and machine learning;
- Identify indicators of compromise and hidden threats that may not be visible to traditional IDS/IPS, antivirus, or endpoint-only tools;
- Analyze application and transport-layer protocols, including HTTP, DNS, SMB, TLS, SSH, and encrypted traffic metadata;
- Map asset relationships and communication patterns to support investigation, segmentation analysis, and threat hunting;
- Correlate NDR detections with Guardsix SIEM and trigger automated response actions through Guardsix SOAR, including host isolation, IP blocking, ticket creation, and analyst notification.
With Guardsix NDR, organizations can:
- Improve situational awareness across network segments and critical infrastructure environments;
- Uncover risks and attack paths that remain outside the visibility of endpoint or perimeter-only controls;
- Accelerate SOC investigations with richer context on assets, communications, and affected systems;
- Streamline detection-to-response workflows through integration with SIEM correlation and SOAR automation;
- Strengthen protection of hybrid, distributed, and sensitive environments without changing the existing network architecture.
Key Features
Sensor-based traffic analysis provides continuous visibility into selected network segments, including data center, perimeter, core network, and internal VLAN environments.
- Behavioral baselining helps identify deviations from normal network activity, including unusual communication patterns, abnormal service usage, and unexpected host behavior.
- Network threat detection covers suspicious connections, reconnaissance activity, lateral movement indicators, command-and-control patterns, and potentially compromised assets.
- Protocol-level inspection allows the solution to analyze enterprise network communications across common protocols such as DNS, HTTP, SMB, TLS, SSH, and related traffic metadata.
- Encrypted traffic analytics use TLS handshake characteristics and fingerprinting techniques to detect suspicious encrypted sessions without decrypting payload content.
- Asset relationship analysis helps security teams understand communication dependencies between systems and identify unusual or risky interactions inside monitored segments.
- Flexible traffic collection supports SPAN, port mirroring, TAP, PCAP, NetFlow, and sFlow, allowing deployment across different physical, virtual, and hybrid network architectures.
- Centralized dashboards and analytical views help SOC teams investigate incidents, validate alerts, review affected assets, and understand network activity in context.
- Integration with Guardsix SIEM and SOAR extends NDR detections with log correlation, incident enrichment, automated response actions, and structured case management.
Guardsix is a unified cybersecurity operations platform combining SIEM, SOAR, NDR, and endpoint telemetry. Recognized for its deep integration capabilities and advanced automation, Guardsix is trusted by public institutions, critical infrastructure, and enterprise customers across Europe.
