Take control of your full attack surface.

Halo Security is a fast, easy, and scalable external attack surface management platform that gives security leaders deep visibility into their internet-facing assets.

Continuous Asset Discovery
Agentless Scanning
Integrated Penetration Testing
Risk-based Prioritization

Manage risk on the modern external network.

Traditional vulnerability and risk management solutions were designed for traditional networks. Halo Security takes the attacker’s perspective to help you identify, assess, and monitor the risks across clouds, third-party providers, and organizational silos.

Trusted by security leaders at companies of all sizes

Discover assets, fast.

You can't protect assets you don’t know about. Our automated solutions identify and catalog known and unknown domains, hostnames, and IP addresses exposed to the internet.

  • Agentless discovery with daily updates
  • Optional connectors with cloud providers like AWS, GCP, Azure, and Cloudflare

Easily contextualize, search, & categorize.

The rich data we collect brings you the context you need to understand what the asset is, what’s running on it, and who’s responsible for it.

  • Easily search and filter targets by technology, ports, locations, issues, and more.
  • Automatically tag and organize targets using advanced rule sets.

Uncover risks
beyond CVEs.

Our agentless vulnerability detection is tuned for internet-facing assets and goes beyond simply detecting known vulnerabilities (CVEs). And yes, we detect those too.

  • Identify issues like subdomain takeovers, domains for sale, forgotten projects, and misconfigured cloud services.
  • Daily scanning keeps your data up-to-date.

Measure &
eliminate risk.

Measure and report on your external risk posture, while prioritizing the issues that matter most.

  • Track the posture of targets, groups of targets, and your full attack surface with risk scores.
  • Prioritize issues using severity ratings and the Known Exploited Vulnerability (KEV) catalog.
  • See details and straightforward remediation guidance on every issue that’s detected.
  • Easily assign and track remediation progress.

Find answers in seconds, not days.

When the next Log4j strikes, you don’t want to be caught running manual exercises to find out if you’re using that software. The Halo Security platform makes it easy to find the most critical insights about your attack surface in seconds.

  • Which assets are hosted outside of the US?
  • Which websites have content-security-policy headers?
  • How many versions of jQuery do we use?
  • Which IPs have port 21 open?
  • What TLS certificates expire this month?
  • How may third-party scripts do we use?
  • What forms are loaded over HTTP?

Built for your workflow.

We offer agentless scanning and single-pane-of-glass visibility out of the box. But we also make it simple to move your data where it makes sense for you.

  • Cloud connectors automatically bring new asset details into the Halo Security platform.
  • Workflow integrations make it easy to get Halo Security data into the tools your team already uses.
