How this list is ordered. Specifiction scores each tool on how fully its maker documents it, whether its prices are published, where the research puts it, the platforms it runs on and whether it can be tried for free (how we rank). Makers can also buy a numbered place (how Specifiction is paid for).

Monitoring frequency, asset limits and API access also help clarify operational fit. Bitdefender Total Security, runZero and Qualys External Attack Surface Management are among the named options. Free-plan availability and paid-from pricing provide cost context alongside the discovery and monitoring details. Consider which environments and asset sources you need to track, and how often you want changes revisited.
