Defend against attacks to help keep your data and network secure

Distributed denial of service (DDoS) attacks compromise your connectivity by sending attack traffic to a server, website, or network resource. This unwanted traffic floods your network. Overloads systems. Slows down services. And can make your network vulnerable to a more malicious attack down the road.

Businesses in any industry are vulnerable. Those hosting sensitive info — like customer information, business records, or financial data — are more at risk. But your enterprise can take defensive measures with Comcast Business DDoS Mitigation Service, available with our Ethernet Dedicated Internet Service.
