Big organisations often use security devices of various brands. Maintaining and management of generated logs of theses devices is an important task for security monitoring. In a recent case, I was asked by an organisation whether they should buy the log analyzer appliance of a specific brand, which they had decided to buy two UTMs from. The organisation have some log analyzer appliances installed in the network. Also the products of the same brand may bring more compatibility and ease of use, the benefits of centralized logging and reporting should not be forgotten.
