NETSCOUT Doubles Arbor Cloud DDoS Capacity to 33 Tbps in 2026

AI-driven, multi-vector DDoS attacks now approach 30 Tbps, forcing enterprises and service providers to rethink how they protect always-on digital services.

DDoS attacks have entered a new era. Mega-botnets such as Aisuru and Kimwolf are pushing attack volumes toward and beyond 30 Tbps, while adversaries combine simultaneous vectors, carpet bombing, and rapid hit-and-run tactics. For CIOs, CISOs, and infrastructure leaders, the question is no longer whether existing defenses can absorb one large flood — it is whether they can sustain operational resilience while multiple critical services are targeted at once.

What was announced

NETSCOUT (NASDAQ: NTCT) announced continued investment in infrastructure and technology to double its Arbor Cloud DDoS attack mitigation capacity to 33 Tbps. The expansion, spanning 16 global scrubbing centers, is expected to be fully completed by the end of August 2026. It follows NETSCOUT's recent acquisition of DDoS network and infrastructure, giving the company end-to-end ownership of the platform delivering cloud-based DDoS defense at global scale.

Unlike cloud mitigation services that simply add bandwidth, Arbor Cloud combines global mitigation capacity with global threat intelligence sourced from NETSCOUT's visibility into real-world internet attack activity. It operates as part of a multi-layered, adaptive DDoS protection design that unites on-premises defense with cloud-based scrubbing via automated cloud signaling, backed by a 24x7 Security Operations Center.

With the increased use of AI, threat actors are targeting organizations whose defenses are vulnerable to the new, more complex DDoS attacks designed to take down critical infrastructure. As enterprises increasingly rely on AI-powered applications and cloud-native services, while at the same time attack size and complexity continue to rise, implementing automated and proactive defenses for uninterrupted availability has become a business risk imperative. Arbor Cloud plays a key role in achieving that objective.

Why this matters

For financial services, healthcare, retail, and public sector organizations, DDoS resilience is now a board-level topic. Multi-vector attacks are the norm, response windows are shrinking, and AI-powered applications multiply the number of always-on services that must remain reachable. According to Markets and Markets, the DDoS protection market continues to grow, driven by more sophisticated attacks and accelerated cloud adoption.

A 33 Tbps mitigation platform gives IT directors and procurement leaders a clear answer to one of the toughest questions in security architecture: what happens when the attack is larger than any single site can absorb. By distributing mitigation across 16 scrubbing centers with consistent policy and intelligence, Arbor Cloud helps ensure that capacity does not become a constraint as attack size and frequency increase.

Technical details

• Global mitigation capacity: 33 Tbps across 16 scrubbing centers, fully owned end to end.
• Intelligent mitigation: Absorbs and blocks larger volumetric and more sophisticated attacks without losing effectiveness.
• Multiple threat mitigation: Handles multiple concurrent targets, including carpet bombing, and multiple attack vectors simultaneously.
• Consistent operational performance: Protects critical infrastructure so capacity is not a bottleneck when attacks scale.
• Faster stabilization post spikes: Acts as a shield wall that prevents collateral damage lasting beyond the attack itself.
• Hybrid architecture: On-premises Arbor defense integrated with Arbor Cloud through automated cloud signaling.
• Threat intelligence: Backed by NETSCOUT's global internet visibility and 24x7 Security Operations Center.
• Rollout: Capacity expansion expected to be fully completed by end of August 2026.
