Axonius: Asset Inventory as the Foundation of Exposure Management

A lot of exposure management problems trace back to a simpler question that’s harder to answer than it sounds: what do we actually own? Axonius started life answering exactly that – Cyber Asset Attack Surface Management (CAASM) – before building exposure management capability on top of a genuinely solid inventory layer.

What is Axonius?

Axonius aggregates data from hundreds of existing tools – EDR, MDM, cloud providers, identity providers, vulnerability scanners, HR systems – via API, with no agents to deploy, to build a single, queryable inventory of every device, user, cloud asset, and SaaS application in the organisation. On top of that inventory, Axonius has built exposure management, SaaS management, and identity security modules that all lean on the same underlying asset graph.

Key features

• Agentless, API-based aggregation – connects to existing tools rather than deploying new sensors, pulling each tool’s own view of the estate.
• Adapter library – hundreds of pre-built connectors to common security, IT, and business tools, so onboarding is largely configuration rather than custom engineering.
• Query engine – a flexible query interface for asking questions like “which devices are missing an EDR agent and have an internet-facing vulnerability” across all connected sources at once.
• Coverage gap detection – specifically surfaces assets that are missing expected controls (no EDR, no patch management enrolment) rather than only reporting on assets that are already monitored.
• Exposure and SaaS management modules – built on the same asset graph, extending from pure inventory into prioritised risk findings and SaaS sprawl visibility.

Who it’s for

Security and IT teams whose first problem is an incomplete or fragmented asset inventory rather than too many vulnerability findings. It’s particularly strong for finding coverage gaps – devices that should have an agent but don’t – which most vulnerability-first tools can’t see because those devices never show up in a scan.

Axonius vs the alternatives

Against CyCognito, Axonius works from the inside out (aggregating what your existing internal tools already know) while CyCognito works from the outside in (discovering what an external attacker would find). Against Tenable One and Brinqa, Axonius puts more emphasis on the asset inventory as the primary product, with exposure scoring built on top, rather than starting from vulnerability correlation.

Getting started

Axonius onboarding is largely a matter of connecting your existing tools’ APIs – a useful first exercise is running the “missing agent” or “unmanaged device” queries against your top few security tools to see how complete your current coverage actually is.
