The software, also called Defender ATP, is already available on Windows and MacOS. It offers features like preventive protection, post-breach detection and automated investigation and response, according to Microsoft.
When it comes to mobile devices, Microsoft's Rob Lefferts told CNBC that the Defender software could help companies protect employees from things like malware and phishing attacks. Apple's and Google's app stores are "pretty safe," Lefferts told CNBC, but "malware does happen on those platforms."
It's unclear exactly when Microsoft will release the antivirus software for iOS and Android, though CNBC reports it'll be available later this year.
