Client Background

Sagemont Advisors is a compliance-focused consulting firm that manages multiple client-facing portals, including compliance management and onboarding systems. Each portal required secure, unified access while minimizing user friction. To support its growing client base, Sagemont partnered with NextGen Coding Company to implement a centralized authentication solution that simplified access and ensured compliance with HIPAA and GDPR standards.

The Problem

Managing authentication separately across multiple portals created challenges for Sagemont Advisors. Users faced repeated logins, inconsistent security policies, and limited flexibility in authentication methods. Administrators struggled with fragmented role management and lacked real-time visibility into login activity. The firm needed a modern authentication framework that could:

  • Enable Single Sign-On (SSO) across portals.

  • Provide Multi-Factor Authentication (MFA) and passwordless login options.

  • Integrate seamlessly with identity providers such as Azure Active Directory and Google Workspace.

  • Deliver centralized admin controls for permissions and access management.

  • Support scalability during compliance deadlines when login traffic spikes.

Without modernization, the platform risked user frustration, administrative inefficiency, and exposure to compliance risks.

Our Solution

NextGen designed and deployed a comprehensive authentication system leveraging Auth.js (formerly NextAuth.js) as the foundation, supported by modern security best practices.

Centralized and Flexible Authentication

  • Single Sign-On (SSO): Enabled one login across all Sagemont portals, reducing friction and improving navigation.

  • Multiple Providers: Integrated OAuth 2.0, OpenID Connect, JWT, and social logins (Google, LinkedIn) for user flexibility.

  • Passwordless Login: Deployed Magic Links and WebAuthn-based biometrics for secure, fast access without credentials.

Advanced Security Layers

  • Multi-Factor Authentication (MFA): Configured with Duo Security and Google Authenticator for OTPs, push notifications, and biometrics.

  • Adaptive Authentication: Middleware flagged untrusted devices or unusual locations, requiring additional verification.

  • Encrypted Session Handling: Sessions stored securely with Prisma ORM and AWS Key Management Service (KMS).

Administrative Control

  • Role-Based Access Control (RBAC): Administrators managed roles and permissions across portals.

  • Centralized User Dashboard: A Next.js/React interface provided real-time session visibility and user management.

  • Compliance Alignment: Full adherence to HIPAA and GDPR through secure tokens, cookies, and encrypted data flows.

Monitoring and Scalability

  • Real-Time Alerts: Integrated with AWS CloudWatch for suspicious activity detection and proactive threat response.

  • Scalable Infrastructure: Deployed on Vercel with serverless architecture to auto-scale during peak logins.

Results

The unified authentication system achieved measurable improvements for both users and administrators:

  • 95% reduction in breaches: MFA and adaptive security eliminated nearly all unauthorized access attempts.

  • 40% faster logins: Single Sign-On streamlined workflows across portals, reducing user frustration.

  • 30% adoption of passwordless access: Users embraced biometric and Magic Link logins for speed and security.

  • 25% less admin overhead: The centralized dashboard simplified role management and reduced manual tasks.

  • 1.5 million logins supported monthly: Scalable serverless infrastructure maintained zero downtime during compliance peaks.

  • 35% boost in satisfaction: Surveys highlighted seamless access, improved convenience, and stronger security features.

  • Enhanced compliance confidence: HIPAA and GDPR adherence improved trust among corporate clients.

Why It Matters

For organizations like Sagemont Advisors, authentication is more than a technical feature—it’s a foundation of trust. A modernized identity system not only strengthens security but also improves productivity, user satisfaction, and regulatory compliance. By streamlining login processes and eliminating vulnerabilities, Sagemont gained an authentication framework built for scale and resilience.

Frequently asked questions

What did NextGen actually build in this engagement?
NextGen designed and shipped a production system end to end: architecture, data model, application code, integrations, security review, and deployment. A senior U.S.-based team owned delivery from discovery through launch, and the client kept full ownership of the codebase and cloud accounts.
How long does an engagement like this take?
Most engagements of this shape run eight to sixteen weeks from kickoff to production. A discovery and architecture sprint takes two to three weeks, the first working release lands around week six, and the remaining time covers hardening, integrations, and rollout support.
What technologies were used?
This engagement was delivered with OAuth, AWS. A senior U.S.-based team owned the architecture and the implementation, and the client kept full ownership of the codebase and cloud accounts.
Can NextGen deliver a similar outcome for us?
Yes. We start with a paid discovery sprint that produces an architecture, a scope, and a fixed price or a staffed team plan. From there you can proceed with a fixed-scope build or a dedicated team. Book a call and we will scope your project against this case study.
