Core CSP
Core Security (Fortra)
Core CSP is a purpose-built security system that is designed to monitor Internet Service Provider (ISP) and telecommunications subscribers for cyberthreats. This lightweight and scalable service provider solution passively monitors extremely large networks and identifies malicious activity on a subscriber network originating from PC, tablet, and mobile devices. ISPs and telecommunications companies must increasingly fend off cyber threats that hijack bandwidth capabilities. These attacks put subscribers at risk of having credentials stolen, falling victim to fraudulent transactions, or having devices commandeered and used for cryptomining, botnets, or other persistent attacks. DDoS attacks, often committed by botnets, are particularly problematic because they consume bandwidth with floods of requests, disrupting normal traffic or crashing the infrastructure entirely. Threat actors use networks to access any number of unsuspecting targets. -
