Exposed database: is your data open to the internet?

Open databases are one of the most common causes of large data leaks. We map your external surface for databases, caches and storage reachable from the internet — without authentication or with default passwords.

What we check

We map your internet-exposed attack surface and look for databases and data stores (e.g. PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, Qdrant, S3-like buckets) responding publicly — especially those without authentication or with default/weak credentials.

Why it matters

An exposed database isn't a vulnerability that needs chaining — it's often directly readable data. GDPR art. 32 makes protection a legal obligation, and exposed stores are one of the fastest routes to a notifiable data breach.

How Security Guru tests it

Maps external ports and services across your attack surface
Identifies database/cache/search services responding publicly
Tests for missing authentication and default credentials (non-intrusive)
Correlates exposed versions against known CVEs (via Threat Radar)

Common mistakes

Database bound to 0.0.0.0 instead of the internal network
Redis/Elasticsearch/Qdrant without auth 'behind the firewall' that happens to be open
Default password left on a managed database
Backup dumps or buckets with data publicly readable

What you get in the report

FAQ

Do you download our data?

No — the check is non-intrusive. We verify exposure and authentication status without exfiltrating content.

What do you cover?

Common databases, caches and search services (SQL, MongoDB, Redis, Elasticsearch, Qdrant, etc.) plus publicly readable object storage.

Is this part of the review?

Yes — exposed data stores are a core part of our external attack-surface review.
