There’s been a lot of speculation as to how much Windows Defender (now Microsoft Defender) will impact the endpoint security market. With the continued prevalence of Windows devices in the corporate endpoint landscape, these endpoints continue to be the most vulnerable and most often attacked. With an increasing cadre of endpoint alternatives with better perceived security available to business users, Microsoft is clearly motivated to close this gap by fortifying the security of these devices in a way that enables its continued dominance in the corporate endpoint market. With a majority of organizations now utilizing Defender in a meaningful way, Microsoft is beginning to gain a foothold as a layered security control on the endpoint, but why aren’t organizations ready to go all in with Defender? And with the recent announcements for Mac support, and Linux support on the way, can Microsoft up its game and become a significant player in endpoint security, changing the endpoint security landscape moving forward?
