Real-time SQL protection for financial data

Safe Boundary intercepts every query that touches cardholder data, financial records, and transaction history, blocking attacks, masking PAN and PII automatically, and generating PCI-DSS audit evidence without a compliance team.

The threat

Financial data is the highest-value attack target

SQL injection remains the number one attack vector for financial databases. The financial sector averages $5.9M per breach , the highest of any industry outside healthcare.

AI agents connected to payment systems, fraud models, and customer data pipelines add a new attack surface that legacy database security tools were never designed for.

The compliance burden matches the risk. PCI-DSS requires:

Access Monitoring

All access to cardholder data environments logged and monitored

PAN Data Masking

Card numbers, IBANs and tax IDs are detected and masked at the proxy before results reach the caller.

SQL Injection Detection

Boolean-blind, UNION-based, and stacked-query patterns are caught and quarantined inline.

Audit Ready Forensics

Every decision is signed and forwarded to your SIEM with full identity and policy context.

Most teams spend 400+ engineering hours per year assembling this evidence manually. Safe Boundary generates it automatically.

Controls

What Safe Boundary enforces

Safe Boundary sits between your application and your database (PostgreSQL, Oracle, SQL Server, or MySQL) as a transparent proxy. Every query passes through it before reaching the database.

PAN tokenization, automatic, real-time

Credit card numbers are detected and masked in query results before they reach any application, service, or AI agent. No manual column tagging. Masking modes: full redaction, partial (****-****-****-4242), or tokenization.

SQL injection prevention, semantic, not signature-based

Every incoming query is parsed to a semantic model and analyzed for destructive patterns. Multi-statement smuggling, transaction-control bypasses (COMMIT inside a read-only call), second-order injection, and stacked queries are caught at the proxy, before they reach the database engine. Pattern-matching firewalls miss these because they read text, not structure.

Least-privilege enforcement at the database layer

Define exactly which tables, columns, and operations each service or AI agent can access. Enforced at the proxy, not trusted from the application.

Real human identity in the audit trail

Every query is attributed to the actual person or service, not just app_user. SSO with Okta, Azure AD, and SAML/OIDC maps connections to named individuals (PCI-DSS Requirement 8).

Time-limited access grants

Temporary elevated access for incidents, compliance reviews, or contractors, with automatic expiry. Every grant and query under it is logged.

Architecture

Architecture for regulated environments

For FinTech companies under PCI-DSS, routing database traffic or cardholder data through a third-party cloud is often a compliance disqualifier.

On Business and Enterprise, both the proxy and the AI classification service deploy inside your VPC, so database queries, PAN samples, and PII detection never leave your environment. Pro deploys the proxy in your VPC but keeps AI classification on shared infrastructure, which is typically out of scope for cardholder-data handling. The cloud control plane handles policies, model updates, and billing only, and never sees query content, result rows, or sampled values.

Architecturally enforced.

Compatible with:

PostgreSQL (Supabase, RDS, Cloud SQL, Azure Database, self-hosted), Oracle (Autonomous DB, RDS, on-prem), SQL Server (Azure SQL, Managed Instance, RDS, on-prem), and MySQL (RDS, Cloud SQL, Aurora, self-hosted).

Audit evidence

PCI-DSS compliance evidence, automatically

Four pre-built reports your QSA already knows how to read, produced continuously from the same query stream that enforces your policy, retained on a PCI-DSS-aligned schedule, and exportable straight into your evidence pipeline.

Structured evidence packages from your query log:

Cardholder data access log , every query that touched PANs and financial records

Admin action log , privileged operations, DDL, permission changes

Daily review attestation , PCI-DSS Requirement 10.7

SQL injection prevention report , blocked and rewritten attempts with rule details

Your QSA gets pre-digested evidence, not a raw log dump.
