A corporate-heavy trust layer beneath a modern interface.

M923 Advisory is designed as a high-trust business advisory experience with conservative data boundaries. The public website is marketing-facing, while financial-data workflows remain server-side and token-based.

This whitepaper summarizes the current v1 posture for the website and portal preview. It is intended for prospective clients, partners, and diligence reviewers and may evolve as the operating environment matures.

The site is built with Next.js and deployed on managed infrastructure. Public pages are separated from server-side API routes that access financial-data providers. The browser never calls Plaid directly.

Plaid integrations use sandbox credentials in v1 for demonstration purposes. Access tokens are supplied through environment configuration, not embedded in client-side code.

Financial-data connectivity is tokenized through Plaid. M923 does not collect or store online banking credentials. Where account data is processed, the goal is to present masked account summaries, operational metrics, and categorized transaction signals that support business advisory workflows.

The current portal preview uses sandbox or local demo data to demonstrate the user experience truthfully and conservatively.

Access to operational systems should follow least-privilege principles and environment-based secret management. Sensitive credentials are expected to remain in deployment secrets, not source code.

Application logging should be sanitized so that raw bank credentials, account numbers, and full transaction descriptions are not written to logs.

M923 maintains a bias toward transparency and containment. Security events should be investigated promptly, scoped carefully, and escalated according to materiality, contractual obligations, and applicable law.

Vendor dependencies with access to sensitive or regulated information should be reviewed periodically for security posture, contractual fit, and operational necessity.
