Vulnerability Assurance

External Attack Surface Assessments

Identify internet-facing assets, exposed access paths, and ownership gaps before prioritizing external vulnerability remediation.

Understand what your organization exposes to the internet

External exposure can grow through cloud deployments, remote support, acquisitions, and forgotten services. An attack surface assessment examines the assets associated with your authorized scope and helps establish who owns them. The aim is a defensible inventory of exposure and next actions, not a claim that every associated internet asset has been discovered.

What the service covers

Map the authorized footprint

Start with approved domains, known infrastructure, and ownership records. Review discovered assets with your team before treating them as in scope for active testing; a shared name or hosting relationship is not proof of ownership.

Prioritize exposure for investigation

Identify externally reachable administration, obsolete services, unexpected hosting, and unclear responsibility. Assess the business purpose of each exposure and route technical weaknesses into an authorized scanning or testing workflow.

Practical deliverables

Scope and deliverables are agreed before work begins. Depending on your environment, the engagement can include:

  • An external asset inventory with ownership confidence and coverage limits.
  • Prioritized exposure findings and investigation tasks.
  • Recommendations for ongoing asset reconciliation and change review.

Is discovery authorization to test an asset?

No. Discovery does not establish permission. Active testing requires confirmation of ownership or appropriate third-party consent and a written scope. Shared infrastructure and supplier systems need particular care.
