Why Leading ISPs Are Replacing Arbor with Radware for DDoS Protection


In an age where digital resilience is paramount, choosing the right DDoS protection solution is no longer optional—it’s essential. For organizations relying on robust, scalable security, Radware is emerging as the preferred alternative to legacy systems like Arbor (NETSCOUT). Here's why top-tier ISPs and MSSPs are switching, and how your business can benefit from this evolution.

Radware vs. Arbor: A High-Level Comparison

Radware’s DDoS protection and infrastructure security solution, powered by its cutting-edge EPIC-AI™ platform, delivers superior defense against modern cyber threats. Unlike Arbor, which often depends on manual intervention and legacy systems, Radware employs real-time behavioral analysis, machine learning, and automation to block attacks before they cause damage.

The ROI of Smart Automation

One of the most compelling reasons organizations are migrating from Arbor is automation. In a recent comparative study by a Tier 1 ISP:

  • Radware achieved 99.1% attack mitigation accuracy, outperforming Arbor's 59.77%.
  • 39.33% fewer manual interventions were needed with Radware.
  • This equates to $1.67 million/year in productivity savings for organizations in the Americas alone.
