Abstract: The invention relates to a method for detecting vulnerabilities in a virtual production server of a virtual or cloud computer system, said system comprising one or more virtual servers. The invention comprises the following steps: a system for analyzing vulnerabilities in the virtual production servers is provided; the system for analyzing vulnerabilities connects to the virtual or cloud computer system; the system for analyzing vulnerabilities requests the cloning of the virtual production server in order to obtain a clone or a disk copy of the virtual production server; the clone or the disk copy is created in the virtual or cloud computer system; the system for analyzing vulnerabilities connects to the clone or to the disk copy; the system for analyzing vulnerabilities analyzes the vulnerabilities of the clone or of the disk copy; the clone or the disk copy is erased; a report analyzing the vulnerabilities of the clone or of the disk copy is generated.
