More About Corero
Corero Network Security focuses on DDoS protection for network operators, cloud and hosting providers, and enterprises that operate internet-facing services. Its offerings are positioned as inline, real-time defenses that System Integration Testing (SIT) in the traffic path to identify and block DDoS traffic while allowing legitimate traffic to continue flowing. This approach targets availability risks for services such as consumer broadband, enterprise connectivity, hosted applications, gaming, and content delivery platforms.
In many deployments, Corero technology (DDoS protection) integrates with edge routers, switches, and scrubbing centers to form a layered defense. Traffic may be steered to Corero appliances or virtual instances for inspection, with policy-based actions that include rate-limiting, filtering, or blocking of attack vectors. The solutions are designed to work with standard internet routing and transport protocols such as Border Gateway Protocol (BGP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and ICMP, as well as with common peering and transit architectures used by Internet Service Providers (ISP) and large-scale data centers.
Corero’s platform (network security) typically uses packet inspection, traffic profiling, and behavior-based detection techniques to distinguish DDoS traffic from normal usage. It addresses volumetric attacks, protocol attacks, and application-layer DDoS patterns within the scope of inline mitigation. For enterprises and providers that already use cloud scrubbing services or upstream mitigation, Corero can operate as an additional inline layer that filters attacks closer to the source, which can reduce the load on upstream links and complement existing security stacks such as firewalls and intrusion prevention systems.
For operational teams, Corero offers dashboards and analytics (security analytics) for visibility into attack characteristics, including source distributions, targeted services, and mitigation rules applied. These capabilities support incident response processes, Service Level Agreement (SLA) reporting for service providers, and capacity planning. The solutions are commonly integrated into network operations centers and Security Operations (SecOps) centers through standard interfaces and management APIs, allowing correlation with other monitoring tools.
Within an enterprise IT and telecom marketplace directory, Corero fits into categories such as DDoS protection, network perimeter security, and service provider security. Its offerings are relevant to network engineering, security architecture, and operations functions that manage high-bandwidth, multi-tenant, or latency-sensitive services, where maintaining availability during hostile traffic events is a primary requirement.
