Lansweeper vs Qualys: asset inventory facts side by side

SHORT ANSWER

Lansweeper describes 3 of the five approaches on the pages we read and Qualys describes 4; they differ on CAASM aggregation, External attack surface management and Exposure management. On collection, Lansweeper offers its own agent and also works without one and Qualys relies on its own agent. Many estates run two of these approaches together, so the question is often which pair, not which one; we do not score either.
