PowerDNS solutions are focused on large-scale DNS service providers, including mobile and fixed-line broadband operators, and hosting and cloud service providers. PowerDNS also underpins scalable security solutions from market-leading vendors. Providers trust PowerDNS to deliver an excellent user experience and protection against DDoS and malware attacks, as well as ensure internet performance for hosters and ISPs. DNS, as the ‘phonebook of the internet’, is a vital part of the infrastructure, needed to provide users with an optimized internet experience. Almost without exception, every action on the internet, from visiting a website, using a service via a mobile app or checking and sending emails, starts with the client looking up the IP addresses of the service using the domain name system. As such, DNS forms a critical control point on the internet, which processes lots of information and personal data. -
