Take control of your IT system
Before we talk about tools: is your IT system really under control today? The seven questions below will tell you in two minutes.
Is your IT system really under control?
Answer honestly — there's no right answer to give, just a status check.
- Do you know which applications are genuinely critical to your business?
- Do you know what they depend on — servers, databases, integrations, providers?
- Is that knowledge held by a single person in your organisation?
- Does your IT provider know more about your IT system than your own company does?
- Do you know which contracts are tied to your critical applications?
- Before a change, can you identify what it risks impacting?
- Could you explain your IT system to a new IT manager tomorrow morning?
If several answers are "no", your problem probably isn't a lack of IT tools. It's a lack of visibility and control over your IT system.
What "being in control" of your IT actually means
Regardless of any tool, control of an IT system rests on four verifiable pillars:
An up-to-date inventory
Every application, server and service has a record: what it's for, who owns it, when it was last verified.
Explicit dependencies
For every component, what it depends on and what depends on it is written down somewhere — not just in one person's head.
Shared knowledge, not concentrated
If the person who "knows everything" is away for a week, the organisation keeps running and deciding.
A history of changes
You can answer "what changed, and why" for any component, without reconstructing it from memory.
How Alerion answers these four pillars
Alerion doesn't replace your IT expertise — it turns these four pillars into a living, automatically maintained repository.
What does this application depend on?
Alerion's IT mapping builds an interactive graph of your components and their dependencies — the question that usually takes a meeting is answered in one click.
See IT mapping in detail →Where are my main IT risks?
Alerion automatically detects inconsistencies — missing dependencies, absent owners, contradictory statuses — before they become incidents.
What do I risk breaking if I change this?
Impact analysis simulates a change before it's executed, based on the real dependency graph.
See change impact analysis in detail →What happens if the person who knows everything is gone?
Alerion's knowledge base centralises and versions what your organisation knows about its IT system — browsable, exportable, independent of any one person.
Secure IT knowledge continuity →What deserves my attention today in my IT system?
Every morning, a summary recaps overnight risks, detected changes and suggested improvements — no need to go looking for the information.
