Overview

NS1, now IBM NS1 Connect, specializes in DNS traffic steering and MultiCDN solutions to optimize application delivery. Founded in 2013 and acquired by IBM in 2023, it serves enterprises needing precise control over traffic routing across multiple CDNs and cloud providers. Its flagship product, NS1 Connect, uses real-time data and automation to enhance performance and resilience. Customers include large-scale organizations in tech, finance, and media sectors. The platform integrates with various CDNs and cloud services to manage global traffic efficiently.

Network & Architecture

NS1 operates a global network with 26 points of presence (PoPs) across North America, EMEA, APAC, and other regions, ensuring low-latency DNS resolution. Its architecture leverages authoritative DNS and real-time data for traffic steering, with robust peering to major cloud providers and CDNs. The platform supports hybrid deployments, combining on-premise and cloud DNS for flexibility. It excels in global coverage but may have less focus on niche regional markets like Africa or the Middle East compared to telecom CDNs.

Features

NS1 Connect offers DNS-based traffic steering with its Pulsar product, enabling decisions based on geolocation, latency, availability, cost, and real-user monitoring (RUM). It includes DDoS protection with autoscaling and filtering capabilities, ensuring resilience against attacks. Real-time analytics and RUM provide insights into network performance. The platform supports API-first automation and Terraform for infrastructure-as-code. Notable integrations include Catchpoint and ThousandEyes for enhanced monitoring.
