Portal Modernization on Azure20–40% Cost Reduction, 99.9% Availability
Sails Software modernized a background screening platform's candidate portal on Azure — cutting infrastructure spend by 20–40%, maintaining 99.9% availability under peak loads, and significantly reducing candidate drop-off.
The client was absorbing escalating on-prem infrastructure costs from rigid legacy database clusters while candidate drop-off rates climbed due to unresponsive verification forms — compounded by the absence of enterprise single sign-on and gaps in data security and PII compliance controls. Sails Software re-architected the entire platform on Azure, hardening the security posture end to end.

- Sails Software as part of a Portal Modernization on Azure initiative migrated a background screening platform from on-prem legacy database clusters, reducing infrastructure spend by 20–40%.
- A .NET 8 and Blazor rebuild of the candidate portal significantly reduced candidate drop-off on mobile and low-bandwidth connections.
- Azure SSO, Microsoft Intune, and Vanta closed identity, endpoint, and PII compliance gaps across the platform estate.
- Datadog observability confirmed 99.9% platform availability under peak screening loads.
The Situation
A background screening and verification platform serving enterprise HR and staffing clients was facing a compound infrastructure problem: legacy on-prem database clusters were generating escalating costs with no path to elastic scaling, the candidate-facing verification portal was causing high drop-off rates on mobile and low-bandwidth connections, and the absence of centralized SSO was creating friction for enterprise clients managing large screening volumes. On top of this, data security measures fell short of the PII compliance obligations inherent to a background screening business. The platform needed a modern foundation — not incremental patches, which is why Sails Software undertook a full Portal Modernization on Azure engagement.
Infrastructure costs were rising without performance improving. The business was paying more for the same — or worse — delivery while candidates were abandoning verification workflows at the point of completion.
HR Technology & Background Screening — serving enterprise HR functions and staffing organizations with candidate verification, identity screening, and compliance workflows.
Identity governance, PII protection, and data security obligations require secure, audit-ready access controls and platform availability commitments that legacy infrastructure could not guarantee.
Why the Status Quo Was Unsustainable
Strategic Need
- Reduce escalating on-prem infrastructure costs without sacrificing platform capability
- Rebuild the candidate portal to reduce verification form drop-off
- Centralize identity governance with enterprise-grade single sign-on
- Establish data security controls and PII compliance fit for a screening platform
- Maintain 99.9%+ availability during peak screening periods
- Create a scalable foundation for future feature development
Key Challenges
- Escalating on-prem infrastructure costs on rigid, inflexible legacy clusters

- Absence of centralized single sign-on (SSO) across the platform estate
- Lack of data security measures and PII compliance controls
- No elastic scaling capability to handle peak screening demand
- Legacy stack blocking future feature delivery velocity

How Sails Software Executed the Engagement
Infrastructure Audit & Migration Planning
This Portal Modernization on Azure phase mapped the full on-prem legacy estate — identifying cost drivers, availability risks, security gaps, and migration dependencies before committing to a migration sequence.
Data Layer Migration
Executed the Azure SQL Managed Instance migration with zero data loss and minimal downtime — establishing the scalable, cost-efficient data foundation for the modernized platform.
Portal Rebuild, SSO & Security Implementation
Re-architected the candidate portal on .NET 8 and Blazor, deployed Azure SSO, and rolled out Microsoft Intune and Vanta — delivering responsive UX, centralized identity governance, and an audit-ready compliance posture.
Observability & Validation
Deployed Datadog across the full platform stack — establishing the monitoring baseline that confirmed 99.9% availability and provided the evidence base for enterprise SLA commitments.
Measurable Results from the Engagement
20–40% Absolute Reduction in Infrastructure Spend
Migrating from rigid on-prem legacy database clusters to Azure cloud infrastructure and Azure SQL Managed Instance eliminated the fixed-cost overhead of maintaining inflexible infrastructure — delivering a 20–40% absolute reduction in infrastructure spend while simultaneously improving reliability and scaling capability.
99.9% Platform Availability Under Peak Screening Loads
The modernized Azure-hosted platform, monitored via Datadog, maintained 99.9% availability across peak demand periods — replacing the instability and manual operational burden of the legacy stack with a reliable, observable foundation.
Candidate Drop-off Significantly Reduced
The rebuilt candidate portal — responsive, mobile-optimized, and re-engineered for low-bandwidth environments — significantly reduced candidate abandonment at the verification completion stage, improving throughput for enterprise clients.
Centralized Enterprise Identity Governance
Azure SSO deployment centralized identity governance across the entire platform estate — eliminating per-client authentication complexity and providing the audit-ready access control that enterprise HR clients require.
Improved Security and Simplified IT Operations
Microsoft Intune brought every endpoint under unified management while Vanta established continuous compliance monitoring — closing the PII and data security gaps of the legacy environment and reducing the day-to-day operational burden on the IT team.

Common Questions
Enterprise technology leaders ask these questions when evaluating this type of engagement.
Azure SQL MI is a fully managed PaaS database engine that handles patching, backups, and high availability — capabilities the client's platform required without the operational burden of managing rigid on-prem legacy clusters. The 20–40% infrastructure cost reduction was a direct result of moving from fixed-capacity on-prem infrastructure to a consumption-aligned managed service.
By migrating to Azure-hosted infrastructure with built-in redundancy, deploying Datadog for real-time observability and proactive alerting, and establishing automated recovery processes. The combination of resilient infrastructure and active monitoring replaced the reactive, manual operations model of the legacy platform.
The legacy portal used forms that were unresponsive on mobile devices and degraded significantly on lower-bandwidth connections — common in candidate environments. The Blazor rebuild addressed both problems with a mobile-first, performance-optimized component architecture, significantly reducing drop-off at the verification completion stage.
Microsoft Intune was implemented for unified endpoint management and Vanta for continuous compliance monitoring, alongside Azure SSO for centralized identity governance. Together these closed the data security and PII compliance gaps in the legacy platform and gave the client an audit-ready security posture appropriate for a background screening business.
