Exposure assessment / External attack surface

See the footprint beyond your asset list.

Your organization presents a larger public footprint than its main website. OPSEQ connects domains, internet-facing services, public records, and visible relationships into an assessment your team can review, assign, and act on. Start with the outside view, then focus validation on the exposures that matter.

OPSEQ / AT A GLANCE

Public asset relationships become an attributed inventory with ownership questions.

01 / Exposure assessment

Establish what belongs to your organization.

Begin with agreed domains, business names, and known infrastructure. Research expands that starting point into a candidate inventory, recording the evidence behind each association. An asset that resembles your organization is not automatically yours. Your team helps resolve uncertain ownership before active validation proceeds, keeping discovery useful without treating every public connection as an authorized target.

FOCUS POINTS

  • Primary domains, subdomains, and related web properties
  • Public service endpoints and visible hosting relationships
  • Ownership confidence, source references, and unresolved questions

02 / Exposure assessment

Connect discovery to a business concern.

An inventory becomes useful when it helps explain risk. We review what is publicly reachable, what the service appears to do, and how that exposure relates to your operating environment. A forgotten support portal and an intentional marketing site deserve different attention. Potential attack paths are documented as hypotheses until an agreed test provides supporting evidence.

FOCUS POINTS

  • Unmaintained or unexpected services that warrant review
  • Public entry points associated with sensitive workflows
  • Priorities based on evidence, reachability, and business context

03 / Exposure assessment

Give the inventory an owner and a next step.

The handoff distinguishes assets to retain, investigate, restrict, or retire. Each finding identifies the observed condition and the reasoning behind its priority. Teams can use the report to reconcile their own inventory and assign work. A later reassessment can compare the agreed footprint after changes, with its coverage and timing defined in advance.

FOCUS POINTS

  • Asset-level actions and suggested responsible teams
  • Clear boundaries between confirmed exposure and inference
  • A defined baseline for a future comparison

BEFORE YOU BEGIN

Common questions.

Can we start without a complete asset inventory?

Yes. A few confirmed domains and organization identifiers can establish a starting point. Newly associated assets still need ownership review and authorization before active testing.

Does this include continuous monitoring?

The assessment covers an agreed scope and period. Recurring reviews can be scoped separately, with a defined cadence and comparison baseline.
