Know the impact before you touch production

Infrastructure changes carry hidden risk. A firewall rule removal that seems routine can break five services nobody knew depended on it. Siriqo models the consequences of any change or compromise scenario against your live network — without touching a single production resource.

  • Model impact of rule changes, peering removal, or subnet changes
  • Compromise scenario simulation from any starting point
  • Results visualised on the interactive topology graph
  • Exportable for change advisory boards and incident records

The problem organisations face

Infrastructure changes carry hidden risk. Organisations routinely make changes without a clear picture of what else will be affected — until something breaks.

Firewall rule changes have unintended consequences

Removing or modifying a firewall rule seems straightforward until it turns out five other services were depending on the traffic it allowed. Without modelling, these dependencies are invisible until they break.

Compromise scenarios are hard to reason about at scale

During an incident, "what can this compromised host reach?" is an urgent question. In a complex multi-cloud environment, answering it by inspection takes hours. You need a live model to query.

Peering and subnet changes affect many teams

Removing a VNet peering or changing a subnet's routing affects workloads that depended on that connectivity. Getting a complete impact list before making the change is nearly impossible without tooling.

Change approval processes lack technical depth

Change advisory boards can only approve what they understand. Without a concrete blast radius analysis attached to a change request, approvals are based on assumptions rather than evidence.

What you get

  • Change impact modelling

    Understand which resources, services, and teams will be affected before making any firewall rule, peering, or subnet change.

  • Compromise scenario simulation

    Model what an attacker could reach from a compromised resource — the same analysis your incident responders need, available before an incident occurs.

  • Graph-visualised impact

    The blast radius is shown directly on the interactive topology map — affected resources highlighted with risk ranking, connections displayed in context.

  • Change management exports

    Export the full impact analysis for change advisory boards, incident records, or compliance evidence — with resource names, sensitivity levels, and affected teams.
