ML, NLP & LLM Data Compliance Tools for Microsoft SQL Server

As businesses modernize their infrastructure with LLM, NLP, and ML-based technologies, compliance with regulations like GDPR, HIPAA, and PCI DSS remains a top concern. This article explains how native features in Microsoft SQL Server and advanced automation from DataSunrise help enterprises secure and govern sensitive data effectively. We’ll explore real-time audit, dynamic masking, sensitive data discovery, and cross-environment policy enforcement—starting with what SQL Server offers out-of-the-box.

Native SQL Server Tools for Data Compliance

Real-Time Auditing with SQL Server Audit

Microsoft SQL Server includes a robust SQL Server Audit feature that allows administrators to capture database-level activity in real-time. You can create server or database audit specifications to monitor SELECT, INSERT, DELETE, or EXECUTE actions on sensitive tables.

Example configuration:

-- Enable audit at server level
CREATE SERVER AUDIT Audit_SQLSecurity
TO FILE (FILEPATH = 'C:\AuditLogs\', MAXSIZE = 100 MB);

-- Enable the audit
ALTER SERVER AUDIT Audit_SQLSecurity
WITH (STATE = ON);

-- Create database audit specification
CREATE DATABASE AUDIT SPECIFICATION AuditSensitiveTables
FOR SERVER AUDIT Audit_SQLSecurity
ADD (SELECT ON dbo.CustomerData BY PUBLIC),
ADD (INSERT ON dbo.Payments BY PUBLIC)
WITH (STATE = ON);

Dynamic Data Masking

Dynamic Data Masking (DDM) in SQL Server protects sensitive information by hiding it from non-privileged users. Unlike static masking, DDM is applied at query runtime without changing the actual data.

Example configuration:

CREATE TABLE dbo.EmployeeRecords (
    EmployeeID INT,
    Name NVARCHAR(100),
    SSN CHAR(11) MASKED WITH (FUNCTION = 'partial(1,"XXX-XX-",4)'),
    Salary MONEY MASKED WITH (FUNCTION = 'default()')
);

With DDM, internal stakeholders can work with real data formats without ever seeing real values—helping enforce the least privilege principle.

Security Management and Discovery

Microsoft SQL Server includes features to enhance security posture. These include Row-Level Security, Transparent Data Encryption, and access policy configuration. However, SQL Server does not provide built-in sensitive data discovery across large, complex schemas or unstructured fields, nor does it offer automated classification or policy recommendations.

That’s where the second half of our solution comes in—extending Microsoft SQL Server with DataSunrise.

Zero-Touch Compliance Automation with DataSunrise

DataSunrise deploys Autonomous Compliance Orchestration for Microsoft SQL Server, combining NLP, ML, and LLM-based tools with zero-touch implementation. Available across cloud, hybrid, and on-prem setups, it supports non-intrusive integration modes such as sniffer, proxy, and native log monitoring.

This flexible deployment ensures continuous data protection while accelerating time-to-compliance with No-Code Policy Automation and Auto-Discover & Mask capabilities.

ML-Based Audit and Behavior Monitoring

DataSunrise applies Machine Learning Audit Rules to track suspicious behavior and ensure real-time activity monitoring. Its Compliance Autopilot aligns your audit scope with GDPR, HIPAA, SOX, PCI DSS, and CCPA policies by learning from previous incidents and behavior baselines.

For instance, if an internal user runs frequent SELECTs on encrypted salary fields, a behavior deviation alert is triggered with automatic risk labeling.

NLP-Powered Sensitive Data Discovery

The platform uses NLP Data Discovery to detect sensitive values, including PII and PHI, across structured and semi-structured fields. OCR scanning for image-based data fields enhances discovery accuracy—vital for hybrid environments with scanned PDFs or screenshots embedded in blobs.

These NLP engines auto-classify columns and apply masking or audit policies with surgical precision, ensuring compliance with SOX or GDPR without relying on manual labeling.

Dynamic Masking and Unified Policy Management

With Dynamic Masking tools in DataSunrise, security teams can apply context-aware masking rules based on user role, location, or behavior—enhancing both RBAC and compliance readiness.

Example use case: a finance analyst accessing from the corporate network gets full data, but remote access triggers field-level masking.

Real-Time Reporting and Compliance Evidence

Through the Compliance Manager, DataSunrise enables Audit-Ready Reporting with one-click generation of reports for auditors and regulators. These are automatically aligned with frameworks such as ISO 27001, SOC 2, and NIST 800-53.

Continuous Regulatory Calibration scans for compliance drift and emerging gaps weekly or monthly—eliminating blind spots in audit readiness.

Conclusion: Autonomous Compliance for SQL Server

By combining native SQL Server features with DataSunrise, businesses can unlock a Unified Security Framework across on-prem and cloud environments. Our solution integrates Zero-Touch Data Masking, ML Audit Rules, NLP Data Discovery, and Compliance Autopilot for full-spectrum coverage.

Unlike traditional tools that require constant manual oversight, DataSunrise delivers autonomous protection with real-time enforcement, centralized dashboards, and intuitive UI—cutting down on operational complexity and ensuring faster compliance with fewer resources.
