A computer implemented method is provided. A number of processor units identify a number of certificates for a device within a network to obtain a file path for each certificate. The number of processor units perform an internal scan of the device to obtain a port number for each active port associated with network protocol on the device. The number of processor units identify a certificate chain associated with each port number based on the network protocol for the device. The number of processor units compare content for each certificate from the number of certificates to the certificate chains for the device to generate a number of matches. The number of processor units generate a data structure including the file path of the certificate for each port on the device based on the number of matches.
