Will the audit help us pass PCI-DSS, HIPAA or GDPR?

Yes. Every finding is mapped to the frameworks you report against: PCI-DSS (read/write auditing on cardholder data), HIPAA (role-targeted PHI-table auditing) and GDPR (data-access controls and logging), so the report serves as auditor evidence.

Do you review authentication and Row-Level Security (RLS) controls?

Yes. We audit pg_hba.conf rules and authentication methods (enforcing SCRAM-SHA-256), role privileges and least-privilege design, and we review or design Row-Level Security policies for sensitive tables.

Is the audit disruptive? Do you make changes to production?

No. Our audits are read-only and non-disruptive. Remediation happens only with your sign-off; we implement fixes with you or hand over a precise runbook.

How do you handle audit logging without flooding a busy database?

We deploy and tune pgAudit using object-level auditing on sensitive tables rather than logging everything, giving you a compliance-grade audit trail right-sized to your workload.

The Problem

"The instance is patched" is not the same as "the database is secure."

Your cloud provider secures the platform. It does nothing about the misconfiguration and excess privilege that cause most PostgreSQL breaches and failed audits, and it can't produce the evidence a regulator asks for.

👤

Excess privilege

Over-privileged roles & superuser sprawl

Cron jobs running as superuser, developers holding admin rights, service accounts with more power than the task needs. No managed-platform SLA reviews who can do what inside your database.

🌐

Network exposure

0.0.0.0/0 sitting in pg_hba.conf

Wildcard access rules, open listen addresses, and permissive RDS/Aurora security groups quietly widen the attack surface. The exposure is one line in a config file nobody re-reads.

🔓

Weak encryption

Unencrypted client connections

Traffic without enforced SSL/TLS is open to man-in-the-middle interception; unencrypted backups are an open door. "It works" is not the same as "it's protected in transit and at rest."

🧾

No evidence

"Who read this table, and when?"

A compliance audit rarely fails because the database was insecure; it fails because there was no proof it was secure: no tamper-evident audit trail, no documented access model, no evidence.

Bottom line

Most PostgreSQL breaches come from misconfiguration and excess privilege, not an unpatched CVE, and audits fail for lack of evidence. Mydbops closes both gaps: we find the exposure and give you the fix and the proof.

What's Included

What's inside a Mydbops PostgreSQL security audit: a fix-first report, not a scan dump

A deep, CIS-Benchmark-aligned review of your PostgreSQL estate, delivered with a clear report and a prioritized remediation plan, where every finding is risk-ranked and tied to a fix.

CIS Benchmark-Aligned Configuration Review

We assess your configuration against CIS Benchmark controls, including file permissions, logging, authentication methods, and secure defaults, scoring each finding by risk.

control-by-control · risk-scored

Authentication & Access Control Review

pg_hba.conf hardening, removal of trust/passwordless logins, SCRAM-SHA-256 enforcement, IP-range restriction, and elimination of wildcard access, ensuring only trusted clients connect.

pg_hba.conf · SCRAM-SHA-256

Roles, Privileges & Least-Privilege Audit

A full role/privilege map, superuser sprawl detection and least-privilege redesign (read-only, developer, admin) so no account carries more power than its job needs.

privilege map · least-privilege

Encryption: SSL/TLS In-Transit & At-Rest

Verify and enforce SSL/TLS for client-server traffic (defeating man-in-the-middle interception), certificate management, plus at-rest and backup encryption review.

TLS enforcement · cert hygiene

Network Security Assessment

Exposure analysis of listen addresses, ports, firewall rules and RDS/Aurora security groups to shrink the attack surface and close unauthorized network paths.

listen addr · ports · SG review

Auditing & Logging (pgAudit)

Deploy and tune pgAudit for a defined, compliance-grade audit trail covering SELECT, INSERT, UPDATE, DELETE, and DDL, answering "who did what, and when" without drowning a busy server.

pgAudit · object-level trail

Vulnerability Assessment

Version and patch-gap analysis, known-CVE exposure, insecure-extension review and SQL-injection surface checks, each paired with prioritized mitigation.

patch gaps · CVE · SQLi surface

Data-Access & Sensitive-Data Review (RLS)

Technical Depth

Real PostgreSQL security depth,the specifics, not a checklist

Our DBAs secure regulated, high-concurrency PostgreSQL in production every day. A Mydbops audit inspects, at minimum, these three pillars.

Access & Identity

Authentication, roles & least-privilege

Every rule and role, examined line by line — so a cron user never carries superuser rights.

trust/peer/md5 vs. SCRAM-SHA-256, password policy

pg_hba.conf rule-by-rule review, no 0.0.0.0/0

How We're Different

Audit vs. scanner vs. cloud default, what you actually get

DIY / open-source scanner

~90 checks

PGDSAT or KloudDBShield can flag CIS checks but not which ones actually put you at risk.

Raw pass/fail, no context or risk-ranking

No compliance mapping

Detection only — you triage the dump

Mydbops Security Audit

Expert judgment

The five findings that matter, how to fix them without breaking your app, and how to prove it to an auditor.

CIS review, expert-reviewed & risk-ranked

Findings mapped to SOC2/PCI/HIPAA/GDPR

Prioritized fix plan + re-test

Delivered by ISO 27001-certified DBAs

Cloud provider default (RDS/Aurora)

Platform only

The provider secures the platform. It does not review your configuration or privilege model.

No CIS benchmark review

No least-privilege / RLS redesign

Platform support, not a security audit

The judgment is the audit. A tool can list ~90 findings; it can't tell you which five put you at risk or how to prove closure to an auditor.

Common Questions

PostgreSQL security audit, answered

A structured, independent review of your PostgreSQL configuration, access controls, encryption, network exposure, logging and vulnerabilities, benchmarked against the CIS PostgreSQL Benchmark. You receive a risk-ranked findings report and a prioritized remediation plan, not just raw scanner output.

Yes. We assess your database against CIS PostgreSQL Benchmark controls authentication, file permissions, logging, secure defaults and more, then risk-rank each finding and recommend the fix. Our methodology is documented in our own PostgreSQL Hardening guide.

Yes. Every finding is mapped to the frameworks you report against. SOC2 gets DDL and connection/access tracking; PCI-DSS gets read/write auditing on cardholder data; HIPAA gets role-targeted PHI-table auditing; GDPR gets data-access controls and logging. The report is built to serve as auditor evidence, not just an internal to-do list.

Yes. We audit pg_hba.conf rules, authentication methods (enforcing SCRAM-SHA-256 over trust/md5), role privileges and least-privilege design, and we review or design Row-Level Security policies for fine-grained access to sensitive tables.

No. Our audits are read-only and non-disruptive, we assess without altering your live system. Remediation happens only with your sign-off, and we can either implement the fixes with you or hand your team a precise runbook.

We deploy and tune pgAudit using object-level auditing on sensitive tables rather than logging everything, which can generate hundreds of GB per day on a high-traffic server. You get a compliance-grade, tamper-evident trail right-sized to your workload.

Yes. We provide RDS/Aurora-specific security reports covering parameter groups, IAM authentication, security groups and encryption settings, the managed-platform controls the cloud default won't review for you.

Those tools flag CIS checks; they can't tell you which findings actually put you at risk, how to remediate without breaking your application, or how to prove closure to an auditor. A Mydbops audit adds certified-DBA judgment, prioritization, hands-on remediation and re-testing.

We're ISO 27001 & ISO 9001 certified and PCI DSS certified, with 10+ years securing open-source databases for 300+ teams. We've published 360+ technical articles and are active PostgreSQL community contributors, you're getting recognized expertise, delivered by certified DBAs.
