runZero vs Sevco: asset inventory facts side by side

SHORT ANSWER

runZero describes 3 of the five approaches on the pages we read and Sevco describes 2; they differ on Agent-based inventory, CMDB-centred inventory and Exposure management. On collection, runZero works without new agents 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.

How do their approaches compare?

Top bar: runZero
Lower bar, lighter: Sevco Security

Full bar: described on the vendor's pages we read
Hatched bar: described with a condition (another product, a higher tier, or part of the approach)
Stub: not in our sources (it may exist; we did not find it)

The bars show what each vendor's own pages describe, or how your answers weigh the five approaches. They are not a measure of how well a product works.

What are the facts, side by side?

Fact	runZero	Sevco Security
Positioning	An asset discovery platform that runZero describes as CAASM: active scanning, passive discovery for fragile OT networks and integrations, with each asset profiled against nearly 1,000 attributes.	Sevco describes itself as an exposure management platform that centralizes vulnerabilities and security control gaps, prioritizes them, and automates and validates remediation, with an accurate asset inventory and asset intelligence as its foundation.
Deployment	SaaS or on-premises, including air-gapped environments; no agents, authentication or appliances required.
