Mobile threat defense (MTD) products protect organizations from malicious threats on iOS and Android devices, at the device, network and application levels. To successfully attack a mobile device, mobile malware must circumvent the controls built into mobile OSs, such as those for app store curation and native mobile OS hardening. MTD products tend to focus on preventing and detecting anomalous behavior by collecting and analyzing indicators of compromise, as well as expected behavior. MTD products gather threat intelligence from the devices they support, as well as from external sources, and use an analysis engine that resides in the cloud, on-premises or on an MTD app installed on devices.
