Clario Tech has a good reputation in the security and privacy industry and they have completely revamped the software as well as their marketing strategy. The current parent company of Mackeeper i.e. Mackeeper has come a long way since then. Moreover, the fact that Mackeeper used to be so hard to uninstall did not help either. This was mainly because Mackeeper's third-party affiliates used extremely aggressive marketing tactics to promote it and the company (Zeobit LLC) did nothing to prevent them from using shady promotion tactics such as pop-ups, unsolicited emails, automatic downloads, etc. In the past, Mackeeper has been under heavy criticism in the Apple community. The current version of the software is actually pretty good at what it does: protecting your Mac from malware and keeping it running at its best. Since then, Clario has taken over the development and distribution of Mackeeper.
At the end of 2019, Clario Tech, a London-based security & privacy company, acquired Mackeeper and its operations from Kromtech. In 2015, Kromtech Alliance Corp, a German-based IT investment and development company, purchased Mackeeper from Zeobit.
It was originally developed and distributed by Zeobit LLC. Mackeeper is a security software with features broadly categorized in four areas: Cleaning, Performance, Security, and Privacy.
