THE MOBILE PROTECTION PARADOX Sitting around waiting for a virus or malware to attack your mobile device just doesn’t make sense. But that’s exactly what most security apps do – they wait for a threat to attack before they spring into action, and by then it can be too late. Plus, lots of the same apps that claim to be there to protect you also peep and pry into your personal data! PROTECTION THAT’S PROACTIVE Not us. At Quokka we think keeping your devices and your personal data safe is not a passive exercise – you have to be proactive. And proactive protection definitely shouldn’t mean your privacy is up for grabs. When it comes to mobile device security, we believe personal privacy and mobile security should live in harmony. Enter Q-Scout! Q-Scout’s proactive protection is always-on to keep you steps ahead of threats. It sniffs out security gaps, alerts you to any app that is behaving badly and tells you how to slam the door in bad guys’ faces…all before threats strike. Q-Scout also hunts for the ways hackers attempt to sneak in through your often overlooked access points like your camera or microphone (yes, they try that, too!) And it does it all without ever touching your private data or content. INTELLIGENCE IN ACTION (IT’S AS SMART AS IT SOUNDS) After identifying threats for more than a decade, our database is massive and wicked smart. Q-Scout uses “Actionable Intelligence” to uncover what the apps on your mobile device are secretly up to. Not everything may be a threat, but if it’s out of the ordinary – like an app accessing your camera without a logical reason – we let you know. Q-Scout gives you the power to tell those apps who’s boss. We push updates for every app and every device literally all the time, so you’re covered for every install, every day. Q-Scout also does all of its heavy computational powerlifting in the cloud, so you can keep on listening, scrolling, and getting those followers up without ever feeling a drag on performance. PROTECTION, WITH A LIGHT TOUCH All this protection comes without snooping into your private, personal data. We think your photos, texts, emails, playlists, and anything else uniquely, digitally “you” is always 100% yours. Q-Scout doesn’t need to dig into your beach pics or texts to Uncle Larry to spot security gaps, so we never do. It’s your device and your data – we’re just here to help keep it all safe. Start living your mobile life knowing you’re ready for threats before they even show up. Q-Scout puts you in control and leaves the bad guys out in the cold!
