See your external exposure before attackers do
Attack Surface Management helps you find what your organization exposes online, understand the risk, and decide what to fix first.

You cannot protect what you do not know you have.
Organizations add domains, cloud services, applications and third-party connections faster than inventories are updated. Forgotten or unmanaged assets stay reachable from the internet, often without an owner.
Security teams then work from an incomplete list. Scans cover known systems while exposed ones go unchecked, and long finding lists give no clear sense of which issue to fix first.
Capabilities at a glance
- External asset discoveryIdentifies internet-facing assets associated with your organization, including ones your own records may be missing.
- Asset visibilityPresents discovered assets in one view so teams can confirm what is theirs, what is unknown and what needs an owner.
- Exposure assessmentLooks at discovered assets for conditions that could be reached or abused from outside, so the exposure is described in concrete terms.
- Risk prioritizationRanks exposures so remediation effort goes first to the items that matter most, with the rationale visible to reviewers.
- Ongoing monitoringTracks changes over time so new or altered exposure is noticed after the first review rather than at the next annual test.
- Threat and risk contextPart of a connected exposure view, so exposure findings can be read next to threat and digital risk information.
From first input to a reviewed decision
The process moves from an unknown boundary to a maintained, prioritized picture of what is exposed.
- 01
Set the starting points
You provide known domains, brands and business units. These seed the search for related external assets.
- 02
Discover
Internet-facing assets linked to those starting points are identified and listed. Your team confirms or rejects each one so the inventory becomes reliable.
- 03
Assess exposure
Confirmed assets are examined for conditions that make them reachable or risky. Findings are described plainly so system owners can understand them.
- 04
Prioritize
Exposures are ranked by likely impact and ease of reach, and reviewers can adjust the order using what they know about the business. The result is a short list to act on first.
- 05
Monitor and repeat
The inventory is revisited over time so changes surface early. New items go through the same confirm, assess and prioritize steps.
Where teams apply it
Shadow IT and forgotten assets
Teams find services and sites that were launched outside normal change control. They can then assign owners or retire them.
Mergers and acquisitions
Security leads review the external footprint of an acquired company before connecting networks. This gives an earlier view of inherited exposure.
Pre-audit and assessment readiness
Compliance and security teams verify that the asset list used for assessment matches what is actually visible online. Gaps are closed before reviewers find them.
Cloud and application growth
As new cloud services and applications go live, the team checks what became reachable. Monitoring catches unintended changes.
Remediation planning
Security managers turn a long list of findings into a ranked plan for system owners. Work is sequenced by exposure rather than by volume.
What it helps your team do
A more complete inventory
Discovery helps close the gap between what you think you expose and what is reachable.
Focused remediation
Ranked exposure helps teams decide what to fix first instead of working through an undifferentiated list.
Clear ownership
Confirming each asset surfaces unowned systems, which is where exposure often hides.
Continuous awareness
Monitoring keeps the picture current between formal assessments.
Evidence for reviews
A maintained asset view supports internal reviews and discussions with auditors and assessors.
Questions we are often asked
What counts as an attack surface?
It is the set of systems, services and information an outsider can reach or learn about, such as websites, domains, cloud services and exposed interfaces. Attack Surface Management focuses on the externally visible portion.
Is this the same as a penetration test?
No. Attack Surface Management is about discovering and monitoring what is exposed. A penetration test is a time-boxed exercise that actively tests specific systems. They complement each other.
Will it find every asset?
No discovery method is complete. Results depend on the starting information you provide and on what is visible externally, which is why your team confirms and extends the inventory.
Does it fix the issues it finds?
It identifies and prioritizes exposure. Remediation is carried out by your system owners, and Valtrenix can advise on planning where engaged.
Which scanning methods and integrations are used?
Technical methods and integrations are confirmed during scoping and are not listed publicly. Your team will see them documented before any engagement begins.
