The global information provider operates proprietary networks supporting hundreds of products, which require constant monitoring.
Malcolm Kelly, global IT security director responsible for operational security at Reuters, said in the past the task of security monitoring was a part of an IT job specification but "it was proving difficult to get dedicated staff for 24x7 monitoring".
Kelly's solution was to sign up with a third-party provider that could offer the company a global service.
One key benefit of the service is that it can offer an early warning of security threats to prevent unpatched laptops from infecting internal company networks. Kelly said, "NetSec monitors other businesses and the internet and so provides an early warning system."
Another contributing factor was that Reuters services are installed in many financial institutions and global businesses and some of the company's clients were asking for reassurances on IT security.
The service works by monitoring Reuters' Enterasys Dragon intrusion detection appliances on its networks. Security information on these devices is sent back to NetSec for analysis.
NetSec provides a secured-access web portal for Reuters which shows the status of security devices, current events, alarms and reports.
The contract with NetSec is part of Reuters' wider security strategy, which, Kelly said, will "enhance our security programme further by building a comprehensive 24x7 monitoring capability with global coverage and a centralised means to track and distribute information and actions about threats and vulnerabilities".
