What is Arbor Sightline
Arbor Sightline is a network visibility and DDoS detection platform used by network operators to monitor traffic, identify anomalies, and support mitigation workflows. It ingests flow telemetry (for example, NetFlow/IPFIX/sFlow) and related routing/context data to provide baselining, alerting, and incident investigation for large networks. The product is commonly deployed by service providers, large enterprises, and security operations teams that need continuous traffic analytics and integration with DDoS mitigation systems.
Flow-based traffic visibility
Sightline centers on flow telemetry collection and analysis to provide broad visibility across high-throughput networks without requiring full packet capture everywhere. This approach fits environments where always-on packet inspection is impractical due to cost or performance constraints. It supports baselining and anomaly detection using historical traffic patterns to help teams distinguish normal peaks from attack behavior.
DDoS-focused detection workflows
The product is designed around DDoS use cases such as volumetric attack detection, top talker analysis, and rapid incident triage. It provides dashboards and alerting that align to common operational workflows in network operations centers and security operations centers. It also supports exporting events and telemetry to external systems for incident response and reporting.
Integrates with mitigation stack
Sightline is typically used as the detection and analytics layer that can integrate with mitigation controls (for example, traffic diversion/scrubbing or on-prem mitigation appliances). This separation of detection from enforcement can fit organizations that already operate routing, firewall, or dedicated mitigation infrastructure. Integration options help reduce manual steps during mitigation and post-incident analysis.
Not a full web security suite
Although it supports DDoS detection and related security analytics, Sightline is not a complete web security platform for application-layer protections such as WAF policy management, bot management, or API security. Organizations often need additional tools for HTTP-layer threats and application security controls. This can increase overall solution complexity for teams seeking a single consolidated web security product.
Depends on telemetry quality
Detection accuracy and investigative depth depend on the availability and fidelity of flow data and supporting network context (for example, routing information and correct exporter configuration). Incomplete sampling, inconsistent exporter templates, or gaps in telemetry coverage can reduce confidence in alerts and limit forensic detail. Teams may need network engineering effort to tune exporters and validate data pipelines.
Operational tuning and expertise
Effective use typically requires baseline tuning, alert threshold calibration, and ongoing operational processes for incident handling. Teams without prior DDoS operations experience may face a learning curve in interpreting traffic anomalies and translating them into mitigation actions. Large deployments can also require planning for collector capacity, retention, and integration with existing monitoring and ticketing systems.
