Armis Centrix™ vs NetSPI Cyber Asset Attack Surface Management (CAASM): Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise security teams managing sprawling IoT, OT, and medical device environments will get the most from Armis Centrix™ because its agentless discovery actually works across protocols most tools ignore. The platform covers all four NIST Identify and Detect functions, with particular strength in continuous asset monitoring and vulnerability prioritization that cuts through noise in environments with thousands of unmanaged devices. Not the pick if you need deep forensic analysis or incident response automation; Centrix prioritizes visibility and risk ranking over post-breach investigation. Mid-market and enterprise security teams drowning in unmanaged cloud and SaaS sprawl need NetSPI Cyber Asset Attack Surface Management for its agentless discovery across internal, cloud, and SaaS environments without requiring infrastructure changes. The platform maps asset relationships and correlates vulnerabilities to control gaps, directly supporting NIST ID.AM and ID.RA functions that most teams skip. Skip this if your attack surface is still mostly on-premises and static; the real value unlocks when you have fragmented cloud tenants and shadow SaaS nobody's tracking.
