CyberPost Advisory

External attack surface intelligence

What can an attacker see about your organization?

CyberPost Advisory maps your external attack surface, identifies security weaknesses, and turns external exposure into actionable intelligence.

You can't protect what you can't see.

Your external attack surface is larger than you think.

Initial exposure check

How exposed is your organization?

Start with a limited external exposure check. Enter your organization's domain to see what is publicly visible from the internet.

The initial check is designed around passive, publicly available information. No intrusive testing is performed against any domain without written authorisation.

The problem

Your external attack surface is constantly changing.

New subdomains, cloud services, third-party platforms, certificates and forgotten systems appear continuously — often without the knowledge of the IT function responsible for defending them.

  • Assets are created faster than they are inventoried.
  • Exposure changes without any internal change request.
  • Attackers enumerate the same public information you have never reviewed.

Flagship engagement

Know what an attacker can see before they do.

CyberPost Advisory performs a structured assessment of your organization's external attack surface to identify what is publicly visible, what may be vulnerable, and where your organization should focus its attention first.

From Exposure to Action

CyberPost Advisory follows a simple process: find what is visible, understand what is weak, validate what is real, and reduce what matters.

01 — Discover

External Attack Surface Assessment

What does the internet reveal about your organization?

We map the systems, infrastructure, applications, and services that are externally visible to your organization.

Explore External Assessment

02 — Identify

Vulnerability Assessment

Which exposed systems could become entry points?

We identify vulnerabilities, insecure configurations, outdated technologies, and other weaknesses across externally accessible systems.

Explore Vulnerability Assessment

02 — Identify

Credential Exposure Assessment

Are your organization's credentials already exposed?

We assess publicly available breach and infostealer-related exposure associated with organizational identities and domains.

Explore Credential Exposure

03 — Validate

Web Application Security Assessment

Could your internet-facing applications be abused?

We assess externally accessible applications for security weaknesses that could expose systems, accounts, or sensitive information.

Explore Web Application Security

03 — Validate

Penetration Testing

What happens when the defenses are actively tested?

Authorized penetration testing validates whether identified weaknesses can be exploited and determines their real-world impact.

04 — Protect

Continuous External Monitoring

Your attack surface changes constantly.

Continuous monitoring helps identify changes to your externally visible environment before they become forgotten exposures.

04 — Protect

Security Remediation

We help you fix what we find.

CyberPost Advisory can help organizations prioritize findings, coordinate remediation, and reduce their external exposure.

  • Remediation planning
  • Risk prioritization
  • Security configuration improvements
  • Vulnerability remediation guidance
  • Retesting
  • Executive reporting

Philosophy

See Your Organization Through an Attacker's Eyes.

An attacker does not begin with your internal network. They begin with what the internet reveals.

CyberPost Advisory maps this external perspective and turns it into actionable intelligence.

How it works

Three steps. One clear picture.

01

Discover

We map your externally visible environment.

02

Assess

We identify weaknesses, exposure, and potential risk.

03

Act

We provide prioritized recommendations and help you reduce exposure.

One assessment. A clearer understanding of your external risk.

Principles

Why CyberPost Advisory?

External Perspective

We begin where an attacker begins: the public internet.

Executive Clarity

Technical findings are translated into understandable business risk.

Evidence-Based

Findings are supported by evidence rather than vague security assumptions.

Action-Oriented

We don't stop at identifying problems. We help organizations understand what to do next.

Security Risk Doesn't Look the Same in Every Industry.
