SimpleumCheck – get to know your Mac better

Knowledge protects

We have developed SimpleumCheck to give you a little insight into which security settings exist and which ones you have activated. It is very important to us that SimpleumCheck is also seen as a kind of “learning program”. Now you can get a little deeper into how the computer and various programs work, and get information about security settings with the help of the action instructions.

Unfortunately, it will be necessary in the future for us all to know better how the computer works in depth and what effects various settings have.

Security Advisor for macOS

Private and Business

SimpleumCheck is a free “security advisor” for Mac. This resourceful little program makes a security check on the computer and shows you what security settings you should make.
On our website we inform in detailed F.A.Q. articles about where and how you can change the settings.

SimpleumCheck is suitable for the private user (Basic-check) as well as for business use (Professional-check). The Paranoid check is aimed at people with very profound computer knowledge and/or special protection needs.

Security versus ease of use and functionality

The Security triangle

Perfect security is a great idea but difficult to implement in practice. Few users will accept it before they can work with the computer to make twenty settings, perhaps on a daily basis. It is always important to establish a balance between ease of use, functionality and security.

Security triangle

The security triangle model is defined by three cornerstones: security, ease of use and functionality. For the user it is most comfortable when the ball rests harmoniously in the middle.

For example, if Bluetooth is turned off, ease of use and functionality are lost, but further security is gained.

Basic-, Professional- and Paranoid-Check

Currently, seventy parameters are checked

Check classes

Basic-Check, Professional-Check and Paranoid-Check provide enlightenment and certainly also some astonishment about which security settings are not enabled by default. All three stages of the checks are always automatically run. You can decide what recommendations you want to follow. The Basic-Check and the corresponding changes of the settings are recommended for each user.

The Professional-Check is particularly valid for professional/business use and is also aimed for secret holder etc… However, we recommend that each user also look at these results and consider the recommendations.

Those who would like to follow the recommendations of the Paranoid-Check are ready to give up comfort and functionality for a high level of security. Here, for example, Bluetooth and the microphone are turned off.
