Why do we talk about a “white vest” in German, when we want to say that a person is of integrity? The expression originates from a time when clean clothing symbolised impeccable conduct. Anyone who had a “white vest” had a clean record and nothing to reproach themselves for – an image that remains highly appropriate in our industry to this day.
As a company operating in the security sector, we bear responsibility – not only towards our clients, but also towards the general public. That is why we require all employees to provide a criminal record certificate that is no more than three months old.
A security service provider is only as good as its people. We place great importance on carefully selected colleagues who are a professional and personal fit for the corporate culture of Safety Line.
The German security industry employs more than 290,000 people – a key factor in internal security. (Source: de.statista.com)
There are over 5,700 security service providers in Germany (as at 27 January 2026; source: listflix.de)
With such density, it is essential that we stand out – through verified reliability, clear values and consistent quality assurance.
The criminal record certificate is only one component – but an indispensable one.
Since 2019, the nationwide Security Guard Register has existed, recording all security companies and their personnel. Authorities can use it to digitally review qualifications and reliability, and to assess them on a daily basis. (Source: destatis.de)
