What does your IT system actually depend on?
A list of applications is not a map. Here's what a real IT map needs to contain — and how Alerion keeps it up to date.
Signs of an insufficient IT map
- Your inventory is a list, not a dependency graph.
- No one knows for certain which components would be affected if a server went down.
- Your last complete mapping is more than a year old.
A real IT map isn't just about listing what exists — it documents how the components hold together.
What a complete IT map needs to contain
The components themselves
Applications, servers, databases, integrations — each with an identified owner, not just a name.
The dependencies between them
What each component needs to function, and what depends on it — in both directions.
The linked contractual elements
The licence contract, the responsible provider, the renewal date — a map that ignores contracts leaves a financial and legal blind spot.
Detected inconsistencies, not just the declared state
A reliable map flags what's missing or contradictory — an absent owner, an inconsistent status — instead of simply reflecting what it was told.
How Alerion maps your IT system
The graph is maintained automatically, rather than rebuilt at every audit.
What does this application depend on?
An interactive graph of your IT components and their dependencies, maintained automatically rather than rebuilt at every audit.
What would be affected if I touched this component?
Each component's blast radius is computed directly from the graph — explore impact paths in one click.

Inconsistencies — missing dependencies, contradictory statuses, orphaned entries — are detected automatically rather than left to manual review.
