Infrastructure usually gets built twice: once quickly to go live, and once again later under pressure, when an audit or an incident exposes the gaps. Secure Infrastructure as a Service delivers the environment in a defensible state from day one - defensible to customers, regulators, and insurers - and we keep operating it afterward instead of walking away once the project ends.
What this includes
- Hardening of Azure tenant, Entra ID, and M365 against a recognised baseline (CIS, Microsoft Secure Score)
- Network segmentation and a Zero-Trust access model for cloud and hybrid environments
- Continuous patch and vulnerability management across servers, endpoints, and cloud resources
- 24/7 monitoring via Microsoft Sentinel with defined escalation paths
- Backup and recovery strategy with regularly tested restore runs
- Monthly evidence and status report for management and audit purposes
How we run it
Baseline review
Document current infrastructure, configuration, and access model. Flag gaps against the baseline.
Hardening
Close the critical gaps first, in priority order. Changes run in controlled windows, with a rollback plan.
Handover to operations
Bring monitoring, alerting, and escalation paths live. Responsibilities clearly split between you and us.
Ongoing operations
Patching, reviews, and evidence collection on a monthly rhythm. Incident escalation under an agreed SLA.
What you get
- Hardened, documented reference configuration for Azure and M365
- Ongoing 24/7 monitoring with defined response times
- Monthly status and evidence report (usable for audits)
- Direct escalation contact for security-relevant incidents
- Quarterly configuration review against the current threat landscape
- Clear handover documentation, should the service move in-house later
Why this matters
Most security incidents do not come from exotic attacks - they come from configuration drift: a firewall rule left open after a change, a patch that sat for three months, an account with excess privileges. Secure Infrastructure as a Service keeps the environment continuously at the agreed standard - not as a project report, but as an operating state we evidence every month.
Questions we get
Do you take over all of IT operations?
No. We take over security-relevant hardening, monitoring, and patch operations for the agreed infrastructure components. General IT support, application development, or helpdesk stay with you or your existing provider - we agree the interface clearly upfront.
Does this work with existing, grown infrastructure?
Yes, that is the normal case. The baseline review in phase one exists precisely for that: we do not take over an ideal world, we take over the real, organically grown environment, and prioritise hardening by risk rather than by wish list.
What happens during a security incident?
Escalation runs through a pre-agreed contact path with a defined response time. For deeper forensic work or crisis communication, we point to our Incident Response offering, which connects seamlessly with ongoing operations.
Is the service limited to Microsoft environments?
The focus is Azure, Entra ID, and M365, because that is the stack we know most deeply and the one most of our clients already run. Hybrid environments with on-premises components are possible - we clarify that in the first call.
