Find exposed internet-facing assets before you're attacked

AI writes exploit code in minutes. Attackers move within the hour. Halo finds what's exposed — including assets you don't know exist — and tells you exactly what to fix first.

You don't need more alerts. You need answers.

Most security platforms assume large teams, dedicated analysts, and unlimited time. Mid-market organizations operate differently.  Unlike most platforms, expert guidance is included. When your team finds something complex, Halo's security experts help you understand the severity and what to do about it. No extra cost. No additional services engagement.

 Book a Free Attack Surface Scan

Your attack surface grows every time you add a cloud service, spin up a new environment, or onboard a SaaS tool. Most teams don't know what's exposed until something goes wrong.

In this free scan, Halo's security experts will show you exactly what attackers can see on your external attack surface — including assets you didn't know existed.

No pressure. No contract. Just answers.

Halo provides:

  • Continuous, automated asset discovery with no agents to deploy
  • Visibility into forgotten projects, shadow IT, and cloud sprawl

  • Optional connectors for AWS, GCP, Azure, and Cloudflare

And when questions arise, our experts are available to help you interpret findings and decide what to tackle first.

Get context you can act on

Raw asset lists don’t reduce risk—understanding does.  Halo provides the right amount of curated context so you know what it is, what’s running on it, and why it matters, while avoiding an inefficient data dump. 

  • Search and filter assets by technology, ports, geography, and risk
  • Automatically tag and organize assets using advanced rule sets

  • Group targets by environment, business unit, or subsidiary

 See what's hiding in your attack surface 

 Most teams are surprised by what Halo finds in the first scan: forgotten subdomains, misconfigured cloud services, third-party exposures nobody owns. Walk through a real discovery and see how Halo surfaces what matters and filters out the noise.

How Halo Works

Circle with 1 icon Halo

Uncover real-world risks beyond CVEs and eliminate them faster. Attackers don’t limit themselves to known vulnerabilities, and neither should your security program. Halo Security detects CVEs and the exposure issues scanners routinely miss. But not all findings deserve equal attention. Halo helps you focus on the risks most likely to be exploited—and helps you fix them efficiently.

Circle with 2 icon Halo

Prioritize with confidence. We prioritize the alerts and curate the context so you can efficiently remediate issues without sifting through a time-consuming data dump. You can:

  • Track risk scores across assets, asset groups, and your full attack surface
  • Prioritize issues using severity ratings and the Known Exploited Vulnerabilities (KEV) catalog
  • See clear remediation guidance for every issue
  • Assign and track remediation progress across teams

Expert help when it counts. For high-impact or complex findings, Halo’s security experts are available to help you validate severity, understand exposure, and provide guidance on the most effective remediation path.
