OUTSIDE Guardian

Analyst-grade context.
After every scheduled scan.

Guardian correlates every verified observation into meaningful change intelligence: Exposure Drift, a living security checklist, evidence-backed recommendations, tailored remediation, grouped workflow alerts, and a weekly executive digest.

Review
A previously observed staging asset is publicly reachable again.
01
Your surface is bigger than you think

Every certificate, DNS record, and subdomain is public. Staging environments, old portals, and new APIs appear on the internet whether or not anyone is tracking them.

02
Attackers start with your domain

An outsider needs nothing but your domain to begin mapping infrastructure. OUTSIDE shows you exactly what that reconnaissance reveals — from the defender's side.

03
Facts, not fear

Every result separates observed fact from inference from possible risk, with confidence scores and evidence. No fabricated vulnerabilities, no sensationalism.

How it works

Enter a domain. Watch the footprint reveal itself.

01
Discover

Passive sources — certificate transparency, DNS, public web signals — surface hostnames and services.

02
Correlate

Assets are normalized and entity-resolved into a single graph with relationship confidence.

03
Classify

Weak signals combine into shadow-asset, non-production, and authentication classifications.

04
Explain

A transparent exposure score and evidence-backed findings tell you what to review and why.

Signature features

Built to be understood in twenty seconds.

Attacker View

A cinematic replay of how public information gradually reveals your infrastructure — starting from a single domain. Ideal for demos and board conversations. Depicts discovery, never exploitation.

Shadow asset detection

Correlated signals — legacy naming, graph isolation, dated technology, absence from your primary site — flag possibly forgotten assets, with the reasoning shown.

Change detection

Repeated scans diff your external surface: new hostnames, returning services, and technology shifts, so nothing appears unnoticed.

Explainable exposure score

A deterministic 0–100 posture score. Open “Why is my score 37?” to see every penalty and mitigation. It measures how contained your surface is — not a probability of being hacked.

Responsible use

A security product, built securely.

Passive by default

The external snapshot uses only public, non-invasive data sources. No exploitation, no brute force, no unauthorized access — ever.

SSRF & egress guarded

Targets are normalized and validated; private, loopback, link-local, and cloud-metadata ranges are refused at a single chokepoint.

Ownership verification

Deeper inspection is gated behind DNS TXT / file-based domain ownership verification. Unverified targets get a clearly-labeled external view.

Rate limited & auditable

Scan quotas, concurrency controls, request timeouts, and structured audit logging keep the platform from becoming a mass-scanning tool.
