Microsoft’s security technology chief is being replaced as part of a wider re-organisation of the company’s platforms and services division.
Security head Mike Nash, who for the last four years has led efforts to convince customers that Microsoft’s products are safe, is taking a sabbatical, said the firm.
With the rise in internet threats and Microsoft still being accused by detractors of not doing enough to make sure its products are up to the challenge, Nash’s role is now being filled by Ben Fathi.
Fathi has come in from Microsoft's storage division, where he was responsible for the Windows file server, network attached storage (NAS) and branch office businesses.
Nash has been with Microsoft since 1991 and was the first product manager for the Windows NT business operating system.
Microsoft said Nash would eventually be returning to the company in another, so far undefined, role.
Fathi will report to Brian Valentine, head of Microsoft's core operating system division.
Other divisions that make up the company’s platforms and services business have also seen senior management changes, as Microsoft moves forward with its on-demand web applications strategy.
