EXTERNAL ATTACK SURFACE

External attack surface assessment

We discover domains, IPs, subdomains, services, cloud resources, panels and technologies visible from the internet. Assets are linked to ownership, actual exposure is validated, and the client receives a prioritized surface map rather than an unverified alert list.

External attack surface mapping
AUTHORIZED AUDITHUMAN VALIDATION
01 / ANALYSIS

From technical signal to a verifiable finding

Identify domains, subdomains, services, technologies and relationships visible from the Internet to reduce unknown exposure.

  • Related asset discovery
  • Reachable ports, services and technologies
  • Relationships between domains, applications and services
  • Prioritization of external paths requiring review
02 / WORKFLOW

How our Red Team works

Automation discovers; specialists validate

01

DISCOVERY

Define exactly which systems and actions are permitted before execution.

02

CONTEXT

Each signal is connected to the asset, exposure and potential impact.

03

VALIDATION

The specialist controls confirmation and final recommendations.

03 / CONTROL

Agreed scope and confidential evidence

Targets, evidence, vulnerabilities and results are shared only with authorized client contacts.

Evidence and context

Each signal is connected to the asset, exposure and potential impact.

Human validation

The specialist controls confirmation and final recommendations.

TECHNICAL SCOPE

What external attack surface analysis discovers

Infrastructure changes continuously. Forgotten domains, temporary services, staging environments and cloud assets can remain visible without being tracked by the team.

01

Domains, subdomains and DNS relationships

02

Exposed addresses, services and ports

03

Observable technologies and components

04

Panels, APIs and development environments

05

Cloud, CDN and provider relationships

06

Potential connections forming attack paths

OUTCOMES

External visibility to reduce unknown exposure

Observed asset inventory

Exposure and priority classification

Relationships across assets and technologies

Recommendations to reduce public surface

WHEN IT HELPS

When we recommend this assessment

✓

After migrations, acquisitions or cloud changes

✓

When the external inventory is outdated

✓

Before penetration testing or Red Team work

FREQUENTLY ASKED QUESTIONS

Direct answers before requesting an assessment

Is this the same as an internal inventory?

No. It shows what an external attacker can discover from the Internet within the authorized scope.

Are third-party assets tested?

Only relevant relationships are documented. Active testing is limited to explicitly authorized systems.

Can you find forgotten subdomains?

The methodology uses DNS, certificate and other signals to identify potentially unmanaged assets.

What happens after discovery?

Exposed assets are prioritized and can move into vulnerability validation or controlled testing if agreed.
