Network exposure
Whether the server is reachable beyond the hosts that need it, and how listen and firewall settings are configured.
Technology Security
Protect the database your application trusts most.
PostgreSQL is trusted with the data that matters, and its security rests on a small set of decisions — who can connect, how they authenticate, what their role can do, and whether the connection is encrypted.

Where PostgreSQL security is won or lost
PostgreSQL gives you precise control over access — and that precision is exactly what gets misconfigured. Host-based authentication rules that are too permissive, roles that carry more than they need, superuser handed out for convenience, and connections left unencrypted are the recurring themes.
We assess who can reach the server, how the authentication rules are written, what each role can actually do, and whether transport is encrypted — then hand back a hardening plan ordered by how directly each item leads to data loss.
Coverage
What we secure on a PostgreSQL deployment
The decisions that determine whether the database is defensible.
Host-based authentication rules
The rules that decide who may connect and how — the most consequential and most misconfigured control.
Roles and privileges
Least-privilege review across roles, and application accounts that carry more than they should.
Superuser sprawl
Who holds superuser and whether they need it.
Transport encryption
Whether connections require TLS, or credentials and data cross the network in clear text.
Risky extensions and settings
Extensions and defaults that widen what a foothold can do.
Version and patch status
End-of-life or unpatched versions with known vulnerabilities.
Deliverables
What you actually receive.
The report is the product. If it cannot be acted on by a developer and understood by a director, we have not finished.
Exposure and access findings
Who can reach and authenticate to the database, and what each role can do.
Least-privilege and role plan
The grants and superuser assignments to remove.
Hardening baseline
Authentication rules, TLS enforcement and safe defaults.
Re-test on fix
Confirmation each change closed the finding.
How we work
Six steps, and no surprises.
The same engagement model applies to every piece of work we take on, so you always know what happens next.
01
Scope
A 30-minute call, then a written scope: what is in, what is out, what we need from you and what it costs. Nothing starts before you sign it.
02
Authorise
Rules of engagement, testing windows, escalation contacts and a signed authorisation. Out-of-hours windows where production cannot take the load.
03
Test
Automated coverage first, then manual testing where judgement is required. Critical findings are reported the day we confirm them, not at the end.
04
Report
One report a developer can act on and an executive can read, with evidence, reproduction steps, business impact and a fix for every finding.
05
Remediate
A walkthrough call with your engineers. We answer questions on the fix, not just the finding.
06
Retest
A free retest cycle to confirm the fixes hold, and a clean summary you can hand to a customer, auditor or board.
Questions
PostgreSQL Security — answered.
The questions clients actually ask during scoping. If yours is not here, ask it directly.
Is the assessment safe to run against a production database?
Yes. It is read-only and non-disruptive; we never modify or delete data, and active checks stay within the agreed scope.
What is the most common serious PostgreSQL finding?
Overly permissive host-based authentication combined with a network path that should not exist — together they let someone connect who never should have been able to. Over-privileged roles are a close second.
Do you need superuser access to assess it?
It helps for the deepest review of roles and settings, but is not required. Without it we assess exposure and authentication externally; with a suitable account we review privileges and configuration directly.
