The message informs that the senhasegura browser did not recognize the certificate of the accessed web page as secure.
In some cases, you can download the certificate on the senhasegura operating system using the orbit fajita import-ca command, as described in the ‘Orbit Command Line Interface’ manual. Some certificates will be recognized by the application, but it is worth stressing that no self-signed certificate is recognized as authentic and consequently not all downloaded certificates will fail to show this message.
It is important to remember that this is not a factor that could compromise the application or the environment in any way, but just a message stating that the site certificate is not recognized as safe, but the usability will be the same.
