企业的很多业务系统已经逐步延伸至移动智能终端。为了防止非法人员窃取企业的电子资料,很多企业将各种电子文件用天喻加密软件(InteKEY)进行了加密保护。KeyFile是专为移动智能终端设计研发的电子文件防泄密APP,KeyFile在经过授权的移动智能终端上能正常使用InteKEY加密后的电子文件,而在没有授权的移动智能终端上不能使用这些加密文件的。有了KeyFile,InteKEY加密文件可以在移动智能终端上安全地使用了。KeyFile必须与InteKEY V8.2或之后的版本配合使用。

Verdict
The clearest difference is in-app purchases: KeyFile at none against Alarm One's 3. KeyFile also leads on iOS requirement (11.0 vs 26.0). Alarm One's advantage is update cadence (every 2 weeks vs every 3 months). On price, ads and device support there is nothing between them.
