Arbor Sightline Reviews & Product Details

NETSCOUT Arbor Sightline is a high-performance network visibility and DDoS detection platform engineered for the demands of large-scale service provider environments. It provides deep, real-time insight into IP traffic by ingesting and analyzing flow data such as NetFlow, sFlow, and IPFIX. For cybersecurity teams, this means having a continuous, comprehensive view of network behavior that enables rapid detection of anomalies, volumetric attacks, and stealthy threats that could otherwise evade traditional perimeter defenses. Designed with scalability and precision in mind, Arbor Sightline empowers practitioners to identify and respond to DDoS attacks with speed and accuracy. It correlates live traffic telemetry with global threat intelligence, allowing teams to pinpoint malicious activity and understand its context within the broader threat landscape. This intelligence-driven approach supports proactive defense strategies, enabling mitigation before service degradation or customer impact occurs. Arbor Sightline also integrates seamlessly with Arbor Threat Mitigation System (TMS) and other mitigation tools, automating response workflows and reducing the operational burden on security teams. Its centralized analytics and customizable dashboards streamline incident investigation and network forensics, helping practitioners reduce mean time to detect (MTTD) and mean time to respond (MTTR). For service providers managing complex, distributed infrastructures, Arbor Sightline is not just a visibility tool—it’s a critical component of a resilient, adaptive security architecture.

"Sightline goes beyond detecting DDoS"

4/5

What do you like best about Arbor Sightline?

I think the best feature in Sightline is the multiple ways we can detect DDoS attacks, using host based or network based signatures. Both of which we use to detect attacks toward our customers, as well as our own infrastructure. The system is easy to deploy in a virtual environment, requiring no additional hardware costs. Sightline is also easily integrated into our customer portal via the available API, which continues to improve with each release. My team is constantly logged into the system, and we see it used daily. The ATAC team is ready to assist with troubleshooting questions, or just general help on how to deal with certain attacks. This gives us confidence in the system, knowing Arbor is there to help. Review collected by and hosted on G2.com.

What do you dislike about Arbor Sightline?

My only issue with Sightline is the approach to the various licenses and features. When running locally on our own hardware, certain items, which as flows per second, shouldn't need an additional license. Review collected by and hosted on G2.com.

What do you dislike about Arbor Sightline?

I find it quite challenging to stop and mitigate DDoS attacks using Arbor Sightline because it can be very manual and labor-intensive without the right tools. This process can be exhausting and difficult. Additionally, I would appreciate more detailed documentation and expanded options in the API to improve integrations.
