Cisco Umbrella's cloud-delivered security enables an immediate improvement in security and compliance posture. That's because DNS is at the heart of every internet connection request. Securing the DNS layer means blocking malicious domains, IP addresses, and cloud applications before a connection is ever established. More than 30,000 organizations depend upon Umbrella DNS to deliver a fast, safe, and reliable internet experience that is simple to deploy and easy to manage. A recent study by GigaOM ranked Cisco #1 in DNS-layer security, and our DNS security contributed to Miercom ranking Cisco #1 in the industry in its laboratory testing of SSE threat efficacy. When you are looking to build upon DNS-layer protection with additional user protection capabilities, including ZTNA, SWG, CASB, DLP, and more, see Cisco Secure Access. Cisco Secure Access features a single client, single manager, and single policy construct protection for multi-function internet access protection and integrated

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.
