Services
Six areas where we deliver measurable value
We are not generalists. Each area is a capability developed in production environments with demanding regulatory requirements.
Enterprise Azure networking
Hub-and-spoke and Virtual WAN topologies with a deliberate routing design, segmentation and traffic inspection — including custom NVAs.
Hub-and-spoke Virtual WAN Custom NVAInfrastructure as Code
Reproducible infrastructure expressed in Bicep, Terraform or ARM — with validation, versioning and a complete audit trail.
Bicep Terraform ARMAzure DevOps and CI/CD
Deployment pipelines with quality gates, environment separation and least-privilege access control.
Azure Pipelines GitHub Actions Release gatesFinOps and PowerShell automation
Cost control and tagging standards enforced across estates containing tens of thousands of resources.
PowerShell Tag governance Cost ManagementGovernance and compliance
Landing zones, subscription hierarchy and policy that sustain compliance without blocking product teams.
Landing Zone Azure Policy RBACArchitecture and security reviews
An independent assessment of an existing Azure estate, with risks ranked by business impact.
Well-Architected Security review Audit Technical depth
Where the reference documentation ends
Enterprise architectures rarely fit the diagrams in the portal. We work at the intersection of routing, security and automation — where design decisions carry real regulatory and financial consequences.
Hub-and-spoke and Virtual WAN
A classic hub with your own NVAs where full control is required, or Virtual WAN where managed scale, multiple regions and branch-to-branch connectivity matter more.
Routing and traffic inspection
Explicit route tables, BGP sessions and prefix filtering, path symmetry for stateful appliances, and east-west inspection in Azure Firewall or your own NVA.
Infrastructure as Code
Versioned Bicep and Terraform modules with policy validation and a complete audit trail for every change made to production.
Automation at scale
PowerShell automation operating across tens of thousands of resources: tag enforcement, FinOps reporting and drift detection.
Products
Tools born out of real project needs
Both products are built on experience gathered during enterprise audits and implementations.
SecureCloudScan
Coming soonAn Azure security scanner. It detects misconfigurations, excessive permissions and deviations from good practice before they turn into an incident.
- Resource configuration analysis
- Risk prioritisation
- Freemium model
AtestoCloud
Coming soonAutomated Azure infrastructure diagramming. It reconstructs the real topology of an environment and visualises dependencies and attack surface.
- Diagrams from live environments
- Security visualisation
- Architecture documentation
Engagement model
How we run projects
- 01
Current state assessment
A review of architecture, configuration and process. The result is a report listing risks ranked by their impact on security, compliance and cost.
- 02
Target design
Architecture documentation with the reasoning behind each decision, the options considered and their consequences — in a form you can take to an architecture board.
- 03
Delivery as code
Implementation through Infrastructure as Code and CI/CD pipelines. Every change is reproducible, reviewed and reversible.
- 04
Handover and governance
Workshops with your team, operational documentation and the controls needed to sustain the standard after the project ends.
