PII & FILE SECURITY FOR BUSY CTOS
Databunker Pro is the vault for user records and sensitive files — with the access controls and audit trail legal asked for. Map every PII field and sensitive file with Claude, lock them down, and make legal happy.
Plus senior engineers on call to help you implement controls.
Already protecting 20M+ records in production. Self-hosted or cloud.
No deck. No sales pitch. A Databunker engineer maps where your user data and files live, and shows you the access + audit setup legal wants — in 20 minutes.
# Ask Claude or Cursor:
"Find every PII field. Plan the migration to Databunker Pro."
→ 47 PII fields found across 9 services:
users.email src/auth/signup.js:42
orders.shipping jobs/import.py:118
logs.payload.phone worker/process.ts:73
...
# Then save each user in Databunker Pro
curl -X POST /v2/UserCreate -H "X-Bunker-Token: $TOKEN" \
-d '{"profile":{"email":"al@x.com","card":"4532..."}}'
{ "status": "ok", "token": "a21fa1d3-..." }Self-host with Docker Compose, Kubernetes, or OpenShift.
“Lock down user data and files, control who can access them, keep an audit trail.” Simple to ask for. But your records are scattered across a dozen systems, your files sit in buckets nobody reviews, and no one can produce a clean log of who touched what.
User records are spread across a dozen databases, 10 Cognito pools, and the service the engineer who left built. Granting access control across all of them — let alone proving it to an auditor — is a week of Slack archaeology.
KYC selfies, ID scans, signed contracts — uploaded to S3 with IAM rules set once and forgotten. Who can download them? When did they last? Legal wants an answer you don’t have.
Access logs are scattered across CloudTrail, app logs, and database audit — where they exist at all. The one thing legal asked for — an authoritative trail of every access — is the hardest to produce.
Scattered data multiplies your attack surface. An ORM bug, a dependency CVE, or a forgotten staging dump leaks real customer names, emails, and cards — and lands on every future pen-test report and security questionnaire.
THE DATA & FILE LOCKDOWN SPRINT
A time-boxed sprint: Databunker Pro plus 40 hours of senior engineering. We lock down your highest-risk records and files together — then your team owns the proven pattern to finish the rest, with no lock-in.
The software
40 hours of senior engineering
We’ll scope the sprint to your stack and tell you whether 40 hours is enough — or if your sprawl needs more.
Once your records and files live behind one vault — with a policy and an audit log on every access — the parts of your job that used to be impossible become routine.
Every record and file has a policy. Granting access, revoking it, or proving it to an auditor is one query — not a week of Slack archaeology.
KYC selfies, ID scans, signed contracts — each one access-controlled and audited. You know exactly who pulled which file, and when.
One authoritative log of every access to every record and file. Hand it to legal, an auditor, or a regulator — no reconstruction across five systems required.
When a prospect’s security questionnaire asks who can touch user data and files, you answer with one diagram and one audit log. Reviews that stalled deals now close them.
The whole migration, in 30 seconds of SQL. Same primary keys, same joins, same indexes — just no PII anywhere except the vault.
Traditional databases store PII directly in tables, making data vulnerable to exposure through logs, backups, and SQL injection attacks—even with RDS encryption enabled.
CREATE TABLE users (
id SERIAL PRIMARY KEY,
email VARCHAR(255), -- Exposed in logs, backups, queries
first_name VARCHAR(100), -- Visible to all database users
last_name VARCHAR(100), -- Accessible via SQL injection
phone VARCHAR(20), -- Stored in application logs
ssn VARCHAR(11), -- High-risk data exposure
created_at TIMESTAMP
);Databunker Pro is a secure user table replacement and vault that encrypts sensitive data (PII, payment info, KYC) and swaps it in your database with safe random tokens.
CREATE TABLE users (
id SERIAL PRIMARY KEY,
user_token UUID -- Safe to store anywhere
);All user-sensitive records are encrypted and securely stored in Databunker’s internal PII vault, featuring fuzzy search, record versioning, encryption key rotation, and multi-tenancy. Fast and secure record lookup is enabled through hash-based search indexes.
Remove PII from your system — compliance becomes trivial
Book a 20-min architecture review →Self-hosted, open-source-friendly, no signup. Four commands and you have a tokenization API on localhost:3000 🔗.
git clone https://github.com/securitybunker/databunkerpro-setup.git
cd databunkerpro-setup/docker-compose-pgsql
./generate-env-files.sh
docker compose up -dThen open http://localhost:3000 — the web UI walks you through generating your root token, wrapping key, and Shamir shares.
curl -X POST http://localhost:3000/v2/UserCreate \
-H "X-Bunker-Token: $ROOT_TOKEN" \
-d '{"profile":{"email":"alice@example.com","card":"4532015112830366"}}'PII goes in. A safe UUID token comes back. Store the token in your application database — never the raw record.

kubectl port-forward service/databunkerpro 3000:3000Three moments in a normal week. Each used to consume your team for days. Now they take minutes — because the data lives in one place, and you can answer for it.
Monday morning
Your DPO pings you: “European customer wants their data deleted.” You point them at the portal. Five minutes later, done. The week-long fire drill is now a Slack thread.
Wednesday afternoon
Enterprise prospect sends a DPA addendum: Indian customer data must stay in Mumbai. Your sales engineer answers on the same call: “Already covered — here’s the architecture diagram.” The deal closes on schedule.
Friday afternoon
Your SOC 2 auditor asks for proof of data location. You hand them the architecture diagram and one access log. The conversation ends in twenty minutes — not three weeks of Slack archaeology.
That is what “paid down PII tech debt” actually looks like — not a slide in the board deck, a line in the next quarter’s wins.
Three CTOs who made the migration. What they got back.
"Databunker Pro saved us 6 months of dev time. The API was a breeze to integrate, and we passed our PCI audit with zero issues."
— Elliot S., Software Director at Cashware
"We ditched our custom encryption for Databunker Pro. It’s faster, more secure, and the team loves the PHP & Python support."
— Sergey M., Cloud Architect at Signature IT
"Open-source roots and military-grade security? Databunker Pro was a no-brainer for our SaaS platform."
— Dmitry K., R&D Manager at Accelario
Six features that turn "consolidate everything to Databunker" from a risky migration into one you only do once. Each one is a tool your senior engineers can defend in design review.
Analytics gets tokens. Support sees last-4. Security gets full reveal. All by policy — not by writing if-statements in twelve services.
CRBAC + masking policies
Hashed search indexes let support find “Johnatan Smyth” even though the vault stores it encrypted. No decryption, no plaintext leak.
Fuzzy search on encrypted data
Every create, every update, every export — captured with an integrity hash. Answer “what did this profile look like on March 14?” in one API call.
Record versioning + audit trail
PostgreSQL Row-Level Security at the database layer means a query for tenant A literally cannot return tenant B’s rows. The database enforces it. Your team doesn’t have to remember to.
Multi-tenancy with RLS
Master key encrypted with your AWS KMS, Azure Key Vault, or HashiCorp Vault. Rotation re-wraps the master key once — your millions of records stay untouched.
BYOK + zero-downtime key rotation
Group users by tenant, region, or processing context. Hand the DPO portal to your privacy team to run DSARs and consent — without engineering involvement.
Group management + DPO portal
Same vault, same evidence, same answer to “where does the data live?” — across every framework your enterprise prospects ask about.
One vault answers consumer-rights requests in seconds — across India and California — with the same audit trail and the same architecture diagram.
Tokens replace PII and card data in your app. Most systems drop out of audit scope. Both frameworks see one source of truth instead of twelve.
Encryption, access control, audit log, key rotation — all evidence your CPA firm can export in one click, not reconstruct across systems.
No. Databunker is written in Go for near-native performance. Token lookups add single-digit milliseconds. We handle 20M+ records in production with no performance issues.
Databunker supports high availability with database replication (PostgreSQL/MySQL). Your tokens remain valid and your app continues to function — PII lookups queue until recovery.
Yes. Start by tokenizing one service or one data type. Databunker runs alongside your existing database. No big-bang migration required.
You choose. Self-host on-premises, in your own cloud VPC, or let enterprise clients host their own vault in any region. You control the data residency.
Self-hosted, cloud, or hybrid — Databunker fits the architecture you already have, and gives you back a single source of truth for PII.
