Qualys vs Sevco: asset inventory facts side by side

SHORT ANSWER

Qualys describes 4 of the five approaches on the pages we read and Sevco describes 2; they differ on CAASM aggregation, Agent-based inventory, External attack surface management, CMDB-centred inventory and Exposure management. On collection, Qualys relies on its own agent and Sevco works without new agents. Many estates run two of these approaches together, so the question is often which pair, not which one; we do not score either.
