Halo Security delivers modern external attack surface management (EASM) designed for organizations that need comprehensive visibility into what’s exposed and enterprise-grade technology—without enterprise complexity, heavy staffing requirements, or endless alerts.
Designed to deliver rapid risk reduction at an affordable price, Halo’s EASM solution enables today’s lean teams to deliver fast value with the perfect amount of context so you can quickly remediate your issues without wasting time sifting through a data dump.
We let you see your internet-facing attack surface the same way attackers do. As organizations grow, their external attack surface expands quickly. New websites, cloud services, APIs, vendors, and acquisitions introduce exposure faster than most teams, especially lean or small teams, can track manually. Forgotten assets and misconfigurations become easy targets.
Our Halo external attack surface management platform is agentless, and our recursive discovery engine continuously discovers known and unknown internet-facing assets. You get a complete, up-to-date view of what’s exposed—so you can prioritize your efforts from a single pane-of-glass.

Visibility is only useful if it leads to action.
Unlike tools that stop at asset inventories, Halo helps teams understand and manage risk, not just collect data. We provide curated context and prioritized findings with a powerful dashboard that lets you easily organize, assign, and track issues. For lean teams, this means less noise, fewer repeat issues, and clearer priorities.
We detect changes as they happen. Discovered assets are enriched with context, changes are tracked automatically, and findings are organized so teams can focus on what’s most likely to be exploited.
Simplify security without sacrificing coverage. From firewall monitoring to penetration testing, you can easily apply the right resources to every asset from our centralized dashboard.
Halo brings discovery, monitoring, vulnerability scanning, and penetration testing together in a single external attack surface management solution. Automated scanning provides continuous coverage, while manual penetration testing reveals real-world attack paths that automated tools miss.
This hybrid approach helps mid-market teams get more value from testing—without managing multiple tools or expanding budgets.
Our black-box approach provides a second set of eyes on the effects of your security initiatives, so nothing falls through the cracks as you scale. Halo’s EASM can:
Halo gives your IT team continuous visibility and support as your business scales—without slowing you down.
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.
Expert support, without enterprise overhead.
Halo is built by experienced perimeter security practitioners who understand how attackers operate. Our platform includes access to remediation experts to validate exposure, discuss emerging risks, and help teams stay focused on what matters most.
For mid-market and lean teams, this means better decisions, faster progress, and fewer blind spots—without hiring more staff.
Whether you’re building your first external attack surface management program or replacing a platform that’s not producing the ROI you need, Halo helps you gain visibility—and turn it into action.

External attack surface management is critical because environments change faster than mid-market and lean teams can track manually. EASM provides continuous visibility, so risks don’t go unnoticed as your business grows.
No. Halo’s external attack surface management platform is designed to help you skip complex, overkill solutions, and get right to risk reduction. Our solution is designed for fast, efficient risk reduction and even includes access to experienced security practitioners for guidance, so it’s perfect for mid-market and lean IT teams.
We provide automated asset discovery, continuous monitoring, and visibility without agents or complex configuration. With flexible workflows and task assignments, your team can quickly track remediation status and stay informed of any attack surface changes.
Most organizations begin seeing results within days. Halo’s agentless external attack surface management platform starts discovering internet-facing assets as soon as it’s deployed—no software installation required.
This fast time-to-value makes it practical for mid-market and SMB teams that want rapid risk reduction.
Traditional vulnerability scanners focus on known assets. External attack surface management goes further by continuously discovering unknown and forgotten assets, monitoring changes, and providing ongoing visibility into everything exposed to the internet.
Halo is the next generation of vulnerability scanning, and we combine external attack surface management with penetration testing to give teams a more complete picture of exposure.
Yes. Halo’s external attack surface management platform continuously monitors cloud-exposed assets across AWS, Azure, and other environments, as well as SaaS applications, APIs, and third-party technologies.
This is especially valuable for mid-market organizations and lean teams with multiple clouds and quickly changing environments.
Yes. Halo Security is a PCI ASV (Approved Scanning Vendor), authorized to perform external vulnerability scans required for PCI DSS compliance.
Halo’s external attack surface management platform helps organizations identify and monitor internet-facing assets, while PCI ASV scans validate compliance requirements—so mid-market teams can manage security and PCI obligations in one place, without separate tools or vendors. Learn more.
Halo simplifies external attack surface management by consolidating discovery, monitoring, and testing into a single platform. Instead of juggling tools, spreadsheets, and manual reviews, teams get a centralized view of exposure that stays current automatically.
This helps mid-market teams maintain strong security without adding headcount.
Not at all. Halo is also used by IT, compliance, and risk teams to understand exposure, support audits, and validate changes during initiatives like cloud migrations or acquisitions.
Yes, we have straightforward pricing that even includes expert human remediation guidance when you need it. Halo is built to be accessible for mid-market and SMB organizations that need strong external visibility without enterprise pricing or operational burden. The platform delivers meaningful coverage and value without requiring large budgets or specialized staffing.
Halo is used by growing organizations across retail, ecommerce, healthcare, SaaS, financial services, and more—especially teams that need better visibility into internet-facing assets without adding complexity.
