Horizon makes it easier for operational teams to understand and discuss security risks and cyberthreats — and plan how to address them.

Skybox Horizon provides unprecedented visibility of the attack surface, including indicators of exposure, giving the insight needed to build a security management program ready to take on cyberthreats.


Integrated with the Skybox Security Suite, Horizon uses contextual intelligence gained from the consolidation and analysis of a variety of data sources to create a visual, interactive model that links network topology, connections and organizational hierarchy.

Horizon automatically finds indicators of exposure (IOEs) — such as unsecure device configurations, risky access rules and exposed, exploited and exploitable vulnerabilities — to give CISOs deep insight into the state of their security from the widest possible range of sources.

What’s an Attack Surface?

Everyone’s got one, but few know what it looks like. The attack surface is the sum total of all the ways in which an IT infrastructure is vulnerable to cyberthreats. Horizon brings your unique attack surface into a single, comprehensive view and provides insight into IOEs.

What are Indicators of Exposure?

A complement to indicators of compromise (IOCs) used to detect attacks that may have occurred, indicators of exposure (IOEs) give insight into potentially exploitable attack vectors before an incident actually takes place. They include issues such as exposed, exploited or exploitable vulnerabilities, unsecure device configurations and risky access rules.



With complete visibility of your network — on-prem, multi-cloud and OT — you have the context needed to make key security management decisions in the face of rapid change, growth and complexity.

Horizon gives security leaders fast insight to their entire attack surface as well as exposures to threats so they can:

  • Take prioritized action against their biggest risks
  • Improve strategy
  • Communicate security issues throughout the organization


Using the interactive attack surface model, drill down to specific sites or networks for quick summaries or zoom out for panoramic visibility across an enterprise. Focus on specific IOEs and risk levels for customized, layered attack surface views.


Visually and quanitfiably report to the board and executives the security status of your entire attack surface or specific business units or locations. Quickly show areas under imminent threat or network weaknesses, ensuring security is front and center across the organization and enabling informed, strategic decisions.

Horizon also provides quick comparisons of current and past IOE levels and charts IOE trends over time, so you can easily track progress toward internal security goals or compliance requirements.
