Running outdated and unsupported versions of software could be posing a risk to enterprise systems, new research has suggested.
A new report from authentication specialist Duo Security into the security health of user devices found that around a quarter of all Windows devices used by businesses around the world are running unsupported versions of Internet Explorer.
Another two per cent of Windows devices are also running versions of the operating system that are no longer receiving security updates.
As a result, Windows users may be exposed to over 700 known vulnerabilities.
Google Chrome was found to be the most up-to-date, with 82 per cent of users currently on the latest version, compared to 58 per cent of Edge and Internet Explorer 11 users, and 66 per cent of Firefox users.
The report cited Google's feature of automatically rolling out updates without user approval as a key driver in its strong performance.
Nevertheless, the weaknesses exposed in the report could have particularly noticeable impact on business mobile users.
Mike Hanley, director of Duo Security, said: "Today obviously users can work from anywhere and more and more work on their personal devices.
"Approximately one in five access attempts for data comes from a mobile device for business use. This has a huge impact on security for organisations, because when you’re talking about BYOD most IT departments don't have visibility into the devices that are being targeted".
The report is likely to strengthen the need for many companies to implement a strong and deliverable BYOD policy.
