Data Security

Trustworthy AI starts
with trusted data.

The data layer we have hardened for years in production — databases, pipelines, access control — now guarding what feeds your models.

FOUNDATION

The layer everything stands on.

AI did not make data security obsolete — it multiplied it. Data that once sat safely inside a database now flows into prompts, embeddings, logs and third-party APIs. Every retrieval corpus is a fresh copy of your crown jewels with a new audience.

We have spent years running PostgreSQL platforms and streaming pipelines in production — that is the DoThinkData practice. DoThinkSecure applies the same field experience to the data boundary of AI systems.

Data layer: structured rows flowing into a secured pipeline
01

Database Security Hardening

PostgreSQL-centric hardening from a team that runs it in production — not a checklist, a discipline.

What we do

  • Authentication and TLS everywhere; SCRAM and certificate rotation
  • Roles, row-level security and least privilege down to schema level
  • Audit logging (pgaudit) with a review cadence that fits your team
  • Configuration and patch discipline; upgrades without downtime
  • Secrets hygiene: no credentials in configs, prompts or agent toolbelts

Deliverables

  • A hardening assessment with priorities
  • Applied configuration changes, reviewed and reversible
  • An audit-log review rhythm
02

Encryption & Key Management

Encrypted at rest, in transit and — increasingly — in use. Keys held by process, not by people.

What we do

  • Encryption at rest and in transit, end to end
  • Column-level encryption and tokenization for PII
  • Key management: generation, rotation, separation of duties
  • Envelope encryption for multi-tenant and AI workloads
  • Data masking for non-production and analytics copies

Deliverables

  • An encryption design that fits your stack
  • A key management runbook
  • Masked staging pipelines — refreshable, like everything else we build
03

Secure Data Integration

Change-data-capture and streaming pipelines (Debezium, Kafka Connect) that stay healthy, trustworthy and observable.

What we do

  • Least-privilege credentials and segmentation between trust zones
  • Integrity checks and reconciliation at every hop
  • Health monitoring with alerting — pipelines that fail loudly, not silently
  • Schema governance and safe evolution
  • Our own Java wrapper exposes Debezium / Kafka Connect health as JMX metrics — battle-tested in production

Deliverables

  • A pipeline security review
  • Monitoring wrapper deployment and dashboards
  • Incident runbooks for pipeline failures
04

Securing the AI Data Boundary

What may enter a prompt is a security decision, not an accident. This is where data security and LLM security meet — and where most AI incidents are actually prevented.

Pairs with retrieval security on the LLM side of the boundary.

What we do

  • Classification: what data may reach models, embeddings and third-party APIs
  • Minimization and masking before retrieval or embedding
  • Chunk-level access control aligned with source-of-truth permissions
  • Ingestion provenance and poisoning prevention for corpora
  • Vector store hardening and retention policy

Deliverables

  • An AI data boundary policy your teams can follow
  • Applied masking and access controls
  • Corpus provenance and poisoning checks
