What is Evidence-Based Vulnerability Management (EBVM)?

Evidence-Based Vulnerability Management is a proactive cybersecurity methodology that shifts the industry away from reactive, volume-based patching toward a deterministic approach. For decades, security teams have managed endless lists of theoretical vulnerabilities. An evidence-based approach replaces this probabilistic guessing with absolute Contextual Certainty through validation of real-world threats.

Instead of relying solely on static Common Vulnerability Scoring System (CVSS) scores or internal vulnerability backlogs, this methodology prioritizes remediation by verifying external asset reachability, confirming the presence of active Proof-of-Concept (PoC) exploits, and tracking government intelligence such as the CISA Known Exploited Vulnerabilities (KEV) catalog. The goal is to identify and secure the raw, unvarnished edge of a network before adversaries deploy automated scanners to hunt for unpatched environments.

How ThreatNG Powers Evidence-Based Vulnerability Management

ThreatNG provides the required external visibility and threat validation to execute an evidence-based exposure management program. Operating as an unauthenticated external scout, ThreatNG maps a digital footprint exactly as an adversary sees it to secure the enterprise against high-impact vulnerabilities.

Connectorless External Discovery

Traditional asset management tools require agents, authenticated API connections, or manual internal seed lists, creating a dangerous illusion of coverage. ThreatNG employs overlapping modules to externally identify infrastructure without requiring internal agents, API permissions, or seeds.

• Technology Stack Investigation: Actively scans the external footprint to uncover unmanaged servers and exposed platforms, such as Microsoft SharePoint.

• SaaS Discovery and Identification (SaaSqwatch): Tracks externally identifiable SaaS applications to map hidden or unapproved shadow cloud collaboration instances that bypass central governance.

• DNS Intelligence: Analyzes domain records and routing information to uncover hidden technology footprints across the digital supply chain.

Evidence-Based External Assessment

ThreatNG stops security teams from relying on theoretical vulnerability lists by providing continuous, evidence-based assessment.

• Example 1: SharePoint Deserialization Flaw Assessment: When a severe Microsoft SharePoint Server deserialization flaw (such as CVE-2026-45659) is disclosed, ThreatNG tracks the CVE against the CISA KEV catalog and active PoC exploits. If DarCache identifies active public exploit listings, ThreatNG validates that the weaponization lifecycle has escalated from theoretical to imminent, allowing teams to prioritize immediate patching.

• Example 2: Header and Infrastructure Exposure Analysis: ThreatNG analyzes HTTP responses and inspects headers for missing security controls or outdated technologies. This provides evidence of structural weaknesses on specific subdomains before a threat actor tests the application for vulnerabilities.

Strategic Reporting and Continuous Monitoring

To maintain continuous protection, ThreatNG transforms raw external data into actionable risk management insights.

• Executive and Board Reporting: By mapping explicit exploit paths, ThreatNG provides Chief Information Security Officers (CISOs) with a definitive, verified security posture for reporting to the Board of Directors.

• Regulatory Compliance Mapping: ThreatNG maps exposed assets directly to regulatory frameworks like HIPAA, GDPR, and DPDPA, while proactively identifying unmitigated risks that could trigger mandated SEC disclosure events, such as Form 8-Ks.

Investigation Modules and Attack Path Mapping

ThreatNG moves beyond surface-level vulnerability data to deliver deterministic, exploit-path intelligence. The DarChain Methodology chains an external exposure directly to its business consequence.

• Example 1: Sensitive Data Leakage via Archived Documents: ThreatNG investigates how adversaries scrape archived versions of company websites (like the Wayback Machine) to find deprecated environments. The investigation module maps how attackers extract accidentally exposed embedded PDFs or XLSX files, analyze the metadata for API keys or credentials, and use that data to execute targeted phishing campaigns or account takeovers.

• Example 2: Subdomain Takeover Execution: ThreatNG investigates deprovisioned cloud-hosted environments where the DNS CNAME record remains active. The module illustrates how an attacker registers the abandoned resource to control the legitimate subdomain, allowing them to host malware or masquerade as the trusted enterprise.

Threat Intelligence Repositories

ThreatNG anchors its findings in empirical threat intelligence to validate risk severity. The ThreatNG Vulnerability Intelligence Repository (DarCache) tracks CVEs alongside a 4-Dimensional (4D) model. This model continuously monitors the CISA KEV, Exploit Prediction Scoring System (EPSS) probabilities, and active PoC exploits to provide concrete evidence of adversarial interest.

Cooperation with Complementary Security Solutions

ThreatNG acts as a high-fidelity external auditor and intelligence engine, feeding real-time, external ground truth directly into complementary internal security platforms.

• Cooperation with Cyber Risk Quantification (CRQ): Traditional CRQ platforms often rely on statistical guesses, actuarial tables, and internal questionnaires. ThreatNG feeds real-world indicators of compromise and behavioral data into these models, serving as a telematics chip to ensure that financial risk calculations are based on external reality.

• Cooperation with Web Application Firewalls (WAF): ThreatNG explicitly validates that defensive controls are actively functioning on newly discovered assets. WAF Discovery confirms whether public-facing SharePoint servers or cloud portals are shielded by active complementary edge defenses.

• Cooperation with Security Information and Event Management (SIEM) & Vulnerability Management (VM): By replacing chaotic multi-day manual fire drills with decisive action, ThreatNG feeds external exposure data into SIEM and VM solutions to enrich internal alerts and ensure security teams address true, actionable risk rather than theoretical noise.
