DDoS protection encompasses the technologies, strategies and services designed to defend against Distributed Denial of Service attacks, in which malicious actors flood a target system with enormous volumes of traffic to exhaust its resources and render it unavailable to legitimate users. Modern DDoS protection typically operates at multiple layers—network, transport and application—using techniques such as traffic scrubbing, rate limiting, geo-blocking and behavioural analysis to distinguish genuine requests from attack traffic.
For organisations subject to compliance frameworks like ISO 27001 or DORA, DDoS protection is a critical component of availability management and business continuity planning. A successful DDoS attack can disrupt customer-facing services, trigger SLA breaches and even serve as a smokescreen for more targeted intrusions, making robust mitigation capabilities essential for both operational resilience and regulatory compliance.
