The review connects public exposure, configuration, access, dependencies and continuity. It separates genuine urgency from foundational improvements and turns both into a practical order of action.

What the assignment should give you

  1. 01A clear view of exposed assets and access
  2. 02Priorities based on likely impact
  3. 03A risk-reduction plan aligned with available resources

How the assignment works

How the assignment works

A short, explicit process adapted to the sensitivity of the situation.

  1. 01

    Scoping

    We define the decision to support, relevant assets, constraints, authorised sources and required confidentiality.

  2. 02

    Investigation

    Collection and analysis follow the agreed scope. Facts, hypotheses and areas of uncertainty remain clearly separated.

  3. 03

    Prioritisation

    Each finding is assessed by reliability, likely impact and the effort required to act.

  4. 04

    Delivery

    You receive a readable synthesis, useful evidence and a roadmap that can be put into practice.

Possible deliverables

Possible deliverables

  • External exposure map
  • Prioritised findings report
  • Hardening and hygiene plan
  • Continuity scenario and incident first steps

Common situations

Common situations

  • Before launch or major change
  • After an alert, visible leak or incident
  • To frame a security roadmap

Before the assignment

Frame a useful decision

A useful exposure baseline starts with assets genuinely under control and clear authorisation boundaries. The review connects external discovery, accounts, configuration and recovery; any intrusive testing needs separately agreed scope.

Information to gather

  • Domains, services and owners to include
  • Critical journeys and known incidents
  • Observation window, exclusions and technical contacts

Decisions to prepare

  • Which access or service should be reduced first?
  • Which exceptions have an owner and expiry?
  • Which restoration capability needs rehearsal?
  • How is a lost event found?
  • Should every API be cached?
  • Is HTTPS enough?
  • Must all old software be replaced?
  • Does no-cache mean no storage?
  • Can a database edit change a passkey’s RP ID?
  • Are a matching digest and valid signature enough?
  • Do three received rows prove three events were retained?
  • Does a CNAME pointing to an error page prove the subdomain can be claimed?
  • Is checking event.origin enough to accept a command?
  • Does a small archive or extraction filter guarantee safety?
  • Is successful ACME renewal enough to close the change?

Illustrative assignment

Situation
An acquisition brings domains and services with no shared inventory.
Work
Cross-check domains, owners, providers and critical journeys; confirm authorisation before active testing; rank each exposure by actual effect.
Deliverable
An owned asset register and reduction plan with closure evidence, dated exceptions and a recovery test.

Example acceptance criteria to agree during scoping

  • Each priority asset has an owner and an authorisation boundary.
  • Forbidden access is denied in authorised tests.
  • Closure records correction evidence and remaining risk.

FAQ

Frequently asked questions

Practical answers to help frame the need before an initial conversation.

Does a cyber exposure review involve intrusive testing?

Not by default. The review starts with external exposure, visible configuration and material supplied with authorisation. Any active testing requires a separate, explicit scope and approval.

What do we receive after the review?

The deliverable ranks findings by impact and urgency, explains corrective measures, identifies possible owners and proposes a realistic order of action.
