As the need for security on the internet continues to grow, one of the the guardians of the networked world lays claim to an enviable record.
In its 13 years in business, VeriSign says it has maintained a "100% up time" service in operating the infrastructure that controls the internet.
The firm has a crucial role in the day-to-day operation of the internet - two of the world's 13 root servers, which direct global internet traffic, are managed by the firm, it routes every web address ending in .com or .net and it issues secure digital ceritifcates to protect more than 900,000 web servers on the net.
