Case Study

Azure Cost Reduction & Security Readiness Case Study

TekClarion reduced the monthly Azure run-rate for a U.S. alternative-investment platform while strengthening cloud security controls and preparing SOC 2 / ISO 27001 readiness evidence.

Operating problem

The Azure environment was carrying avoidable spend while security evidence needed to mature.

The estate ran across a multi-subscription hub-and-spoke Azure architecture with AKS, App Service, Azure SQL, ADLS Gen2, Event Hubs, Front Door, Application Gateway, Key Vault, Databricks, Synapse, Log Analytics and Sentinel in scope.

The business needed a cost-down program that did not weaken reliability or delay compliance readiness. Spend reduction, access control, cloud security posture and audit evidence had to move together.

Work performed

TekClarion treated cost reduction as controlled cloud operations, not isolated resource deletion.

Storage and data estate cleanupReviewed ADLS Gen2, snapshots, disks, backups and retained data patterns to identify orphaned, duplicated and over-retained resources.
Networking and perimeter reviewAssessed public IPs, load balancers, Front Door, Application Gateway and network-security configuration for unnecessary cost and control exposure.
Compute and database right-sizingReviewed virtual machines, AKS usage patterns, Azure SQL configuration and analytics workloads for right-sizing, scheduling and reserved-capacity opportunities.
Security-control hardeningImproved RBAC, PIM, Conditional Access, MFA coverage, Defender posture, Sentinel logging and process controls in parallel with spend reduction.
Readiness evidenceOrganized evidence and operating artifacts needed for SOC 2 and ISO 27001 readiness rather than leaving the work as undocumented portal changes.
0170% run-rate reduction

Monthly Azure run-rate was reduced beyond the original 50% target.

02Secure Score to 82%

Security posture improved while the cost-down program was executed.

03100% MFA and PIM coverage

Privileged access and identity controls were tightened.

04Zero production downtime

Changes were executed without production downtime from the optimization work.

Evidence left behind

The result was a cleaner Azure estate with stronger control visibility.
