Netscout strengthens operational resilience

July 24, 2026

Netscout, a provider of observability, AIOps, cybersecurity, and DDoS attack protection solutions, has announced continued investments in infrastructure and technology to double its Arbor Cloud DDoS attack mitigation capacity to 33 Tbps, which is aimed at keeping critical digital services available during DDoS attacks, protecting revenue-generating digital operations, supporting always-on AI-driven businesses, and maintaining customer trust. 

Netscout says that this capacity enhancement, coupled with its recent acquisition of DDoS network and infrastructure, reinforces its commitment “to delivering industry-leading cloud-based DDoS defence at global scale”.

“With the increased use of AI, threat actors are targeting organisations whose defences are vulnerable to the new, more complex DDoS attacks designed to take down critical infrastructure,” stated Carlos Morales, SVP and general manager, Arbor Cloud, Netscout. “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 defences for uninterrupted availability has become a business risk imperative. Arbor Cloud plays a key role in achieving that objective.” 

Increasing Arbor Cloud capacity provides significant advantages, including: 

  • Greater intelligent mitigation capacity – absorbs and blocks larger volumetric and more sophisticated attacks without losing effectiveness 
  • Multiple threat mitigation – handles multiple concurrent targets (e.g. from carpet bombing attacks) or multiple attack vectors simultaneously 
  • Consistent operational performance – protects critical infrastructure, ensuring capacity does not become a constraint as attack size and frequency increase 
  • Faster stabilisation post spikes – acts as a shield wall preventing attacks from reaching customer infrastructure and creating collateral damage that lasts well beyond when the actual attack subsides 
  • Operational confidence – provides added assurance for mission-critical sectors, like financial services, hospitals, retail, and the public sector, which require that protection remains available when legitimate traffic surges and cyberattacks occur simultaneously 

Arbor Cloud plays a critical role as part of Netscout’s multi-layered, adaptive DDoS protection, combining on-premises DDoS defence with cloud-based traffic scrubbing services that are tightly integrated via automated cloud signalling. This hybrid design stops attacks as close to the source as possible while seamlessly absorbing loud volumetric attacks in the cloud. Offering comprehensive global protection, Arbor Cloud is supported by a 24/7 Security Operations Centre staffed by Netscout’s DDoS protection experts. The capacity expansion is expected to be fully completed by the end of August.
