An apparatus for securing a cloud-provider system includes one or more network interfaces and one or more processors. The network interfaces are configured for connecting to a network. The processors are configured to allocate resources of the cloud-provider system for use by tenants of the cloud-provider system, to allocate to the tenants one or more Internet Protocol (IP) address ranges, to assign multiple IP addresses, scattered across the IP address ranges, for use by one or more honeypot servers, and to secure the cloud-provider system against hostile attacks, by processing network traffic associated with the assigned IP addresses using at least the honeypot servers.
