Learn from the latest global observations.

Know the risks to your organization, even if you don’t own the assets

Your attack surface extends to supply chain partners, third-party vendors and acquired companies. Control those risks and find the right stakeholders to quickly mitigate issues.


Centralize oversight of your organization’s attack surface risks by monitoring for vulnerabilities with supply chain partners and third-party vendors.

  • Traditional asset inventory is slow and error-prone

    Don’t assume third parties or acquired companies can provide an accurate picture of their security, including assets created on your behalf.

  • Attack surface reduction

    Adding partners or acquiring a company shouldn’t mean inheriting security risks. Control your attack surface and stop risks before they become headlines.

  • Supporting stakeholders

    Improve security by ensuring risky asset management is routed to the responsible stakeholder, whether in your organization or a third party.

Your partners = your risk

Your partners = your risk

Complete Attack Surface Management

An attacker view of your attack surface

Internal scans are only as effective as the assets inventory they review. Scanning from the outside-in ensures a complete view of all internet-connected assets that pose a risk to your organization, especially if they belong to someone else.

  • Don’t inherit risk through M&A

    Just as Xpanse can build a record of your assets, it can do the same for an acquired company.

  • Discover third-party exposures

    Xpanse Link finds the internet-connected assets owned by third-party vendors or supply chain partners that could put your organization at risk.
