Insiders recently indicated that Google was moving away from using Windows internally due to security reasons. In response to this, Microsoft offered a blog post supporting their own case.
“There is some irony here that is hard to overlook,” writes Brandon LeBlanc. “For starters, check out this story from Mashable a few months ago where it was reported that Yale University had halted their move to Gmail (and their move to Google s Google Apps for Education package) citing both security and privacy concerns.”
“When it comes to security, even hackers admit we re doing a better job making our products more secure than anyone else,” noted LeBlanc. “And it s not just the hackers; third party influentials and industry leaders like Cisco tell us regularly that our focus and investment continues to surpass others.”
The post goes on to note that Microsoft updates Windows frequently to close security loopholes and that Windows 7 has additional features, like BitLocker, Parental Controls and Address Space Layout Randomization to protect its users.
