Network security architecture
A network designed so that one incident does not become a company-wide crisis.
Value for your organization
- What do we get?
- A documented, segmented network with clean firewall policies, ready to contain an incident.
- Why trust you?
- Led by a consultant with more than 20 years designing and securing networks for banking, the public sector, healthcare and defense.
- How long does it take?
- Review and report in 1–2 business weeks, depending on the size of the organization. Implementation is then planned in phases.
- What do you need from us?
- About 3–4 hours of your team’s time in total: a kickoff meeting, access to the information we request, and the results presentation.
- How will we know it worked?
- Updated diagrams, justified rules, and documentation you can present to auditors, customers and insurers.
Context
Many organizations have grown their network in stages and moved services to the cloud without a common security design. The result is infrastructure that is hard to document, with accumulated firewall rules and no separation between critical areas. This service puts that infrastructure in order and prepares it to grow safely.
What it brings
- Visibility
- A clear map of your network, its connections and its critical points.
- Containment
- Separate zones so a problem in one area does not reach the others.
- Order
- Firewall policies that are clean, documented and justified.
- Consistency
- The same level of security on your local network and in the cloud.
- Evidence
- Documentation ready for auditors, customers and insurers.

Frequently asked questions

- Changes are made in agreed maintenance windows, each with a rollback plan.
- Do you work with our IT team or current provider?
