Bitsight Attack Surface Intelligence

Attack Surface Intelligence

Bitsight combines external attack surface intelligence and AI-driven threat intelligence into one solution. Discover every asset, prioritize business-critical vulnerabilities, and lock down exposure before attackers find it.

Uncover blind spots and make unknown assets, known.

As organizations grow, their digital footprints expand, increasing the number of vulnerabilities and attack vectors. Bitsight Attack Surface Intelligence offers real-time visibility into assets, prioritizes critical risks, and helps strengthen defenses.

Bitsight Attack Surface Intelligence (ASI) goes further than traditional EASM by fusing real-time discovery with AI-curated threat intelligence from the deep, dark, and clear web. The result: a single view of every known and unknown asset, with active threat context, business-criticality scoring, and early warning on emerging exploits so that security teams can act on the exposures that actually matter.

Where attack surface management meets cyber intelligence.

Continuous discovery

Automatically discover and map every externally facing asset, including domains, subdomains, IPs, certificates, cloud services, SaaS exposure, and shadow IT for real-time visibility in a single view,

  • Inventory all internet-facing systems: domains, subdomains, IPs, hosts, software, CVEs, certificates, cloud storage, and exposed services
  • Detect shadow IT and unsanctioned assets across AWS, Azure, GCP, and SaaS environments
  • AI-synthesized asset summaries surface anomalies and high-risk exposures instantly

Asset prioritization

Cut noise and focus on the exposures that matter, including: assets ranked by business criticality, exploit likelihood, and active threat context.

  • User-defined asset classification by business criticality, ownership, and regulatory exposure
  • AI-driven risk scoring that combines asset value with real-time threat intelligence
  • Customizable labels, tags, and on/off monitoring toggles for every discovered asset

Real-time threat intelligence

Correlate every asset with active threat context from the clear, deep, and dark web, and prioritize based on real-world exploit likelihood, not just CVSS scores.

  • Prioritize vulnerabilities with Bitsight's DVE (Dynamic Vulnerability Exploitability) Score — informed by active exploitation, dark web chatter, and ransomware targeting
  • Auto-attribute high-risk CVEs to affected assets and devices, mapped to MITRE ATT&CK
  • Run threat hunting and incident response investigations scoped to your specific assets

Seamless scalability

Built for the world's largest enterprises to secure attack surfaces across subsidiaries, business units, and post-M&A environments.

  • Automatic asset mapping from day one with no manual onboarding required
  • Multi-tenant architecture for parent companies, subsidiaries, and managed-service deployments

Attack Surface Intelligence FAQs

What is Attack Surface Intelligence (ASI)?

Attack Surface Intelligence (ASI) is an evolution of External Attack Surface Management (EASM) that combines continuous asset discovery with real-time threat intelligence from the clear, deep, and dark web. Where traditional EASM tells you what is exposed, ASI tells you which exposures are actively being targeted, enabling security teams to prioritize and remediate based on real-world threat context rather than just CVSS scores.

Why is ASI important for modern organizations?

As organizations adopt cloud, expand globally, and grow through M&A, their digital footprints expand faster than security teams can track — averaging 30% unknown or unmanaged assets across most enterprises. Each blind spot is a potential entry point. ASI continuously discovers every asset, correlates it with real-time threats from the deep and dark web, and surfaces the exposures attackers are actively targeting — closing the gap between what's exposed and what's defended.

What are the key benefits of ASI?

  • Prioritized Risk Management: Focus resources on the most critical vulnerabilities with real-time, actionable intelligence to reduce noise and alert fatigue.
  • Scalable Security: Seamlessly secure assets during periods of growth or digital expansion.
  • Proactive Threat Defense: Identify emerging threats, uncover unknown assets, and mitigate vulnerabilities before attackers can exploit them.
  • M&A and Subsidiary Visibility: Map the digital footprint of acquisition targets and subsidiaries to surface inherited risk during due diligence.
  • Regulatory Compliance: Meet requirements under NIS2, DORA, SEC cyber disclosure, NIST CSF, and ISO 27001 with continuous asset monitoring and exposure tracking.

What's the difference between EASM and Attack Surface Intelligence?

External Attack Surface Management (EASM) focuses on discovering and inventorying internet-facing assets — domains, IPs, certificates, cloud services, and shadow IT. Attack Surface Intelligence (ASI) extends EASM by adding real-time threat intelligence from the deep, dark, and clear web, so security teams know not just what is exposed, but which exposures are actively being targeted by threat actors.

How does Bitsight ASI compare to other EASM platforms?

Bitsight ASI differentiates from other EASM platforms in four ways: (1) integrated threat intelligence from 1,000+ underground forums and 7M+ daily intelligence items, (2) the proprietary DVE Score that prioritizes vulnerabilities based on real-world exploit likelihood (not just CVSS), (3) named recognition as a Leader in the Frost Radar™ for EASM and a Visionary in the 2026 Gartner® Magic Quadrant™ for Cyber Threat Intelligence Technologies, and (4) deep integration with Bitsight's broader cyber risk intelligence platform spanning third-party risk and security ratings.

What asset types does Bitsight ASI discover?

Bitsight ASI discovers and maps every externally facing asset, including domains, subdomains, IPs, hosts, certificates, software, CVEs, cloud storage, SaaS services, exposed databases, and shadow IT across AWS, Azure, GCP, and other cloud environments. Assets are automatically attributed to your organization via Bitsight's AI attribution engine and continuously refreshed as your footprint evolves.

How does Bitsight ASI integrate with vulnerability management and SIEM tools?

Bitsight ASI integrates with leading vulnerability management, SIEM, SOAR, and ITSM platforms — including Splunk, Microsoft Sentinel, ServiceNow, Jira, Tenable, and Qualys — to push asset inventories, prioritized vulnerabilities, and threat intelligence directly into existing security workflows. A robust API supports custom integrations for any internal tooling.

Which industries does Bitsight ASI support?

Bitsight ASI supports attack surface management across financial services (banks, insurance, capital markets), healthcare and life sciences, energy and utilities, manufacturing, retail, technology, and government. Industry-specific use cases include subsidiary mapping for global banks, OT/IT convergence visibility for energy providers, HIPAA-aligned asset monitoring for healthcare systems, and CMMC/FedRAMP supplier oversight for U.S. government contractors.
