• Analyze NodeZero findings, attack paths, vulnerabilities, compromised credentials, privilege escalation opportunities, and lateral movement paths.
• Validate automated findings through manual testing where appropriate.
• Translate NodeZero attack-path findings into actionable remediation recommendations.
• Prioritize exposures based on demonstrated exploitability and potential business impact.
• Track remediation of NodeZero findings and perform follow-up validation.
• Use Horizon3.ai results to identify weaknesses in preventative and detective security controls.
• Collaborate with infrastructure, network, identity, and security engineering teams to eliminate validated attack paths.

Attack Path Analysis:

• Analyze how individual vulnerabilities can be chained together to create a meaningful security risk.
• Identify potential paths from: Initial access Credential compromise Privilege escalation Lateral movement Domain/enterprise compromise Access to critical systems.
• Use offensive-security techniques to validate high-risk attack paths.
• Identify excessive privileges, insecure trust relationships, weak authentication, vulnerable services, and network segmentation weaknesses.
• Recommend controls that break or eliminate attack paths.

Vulnerability Management & Risk Prioritization:

• Analyze vulnerability scanner output and identify exposures requiring remediation.
• Validate high-risk vulnerabilities through authorized exploitation.
• Prioritize vulnerabilities using: CVSS CISA KEV Exploit availability Asset criticality Business impact Threat intelligence Actual exploitability Attack-path context.
• Identify vulnerabilities that present immediate or material risk to the organization.
• Partner with infrastructure and application teams to establish remediation plans.
• Retest vulnerabilities after remediation.

Threat Intelligence:

• Research emerging vulnerabilities, exploits, threat actors, malware, and attack techniques.
• Monitor CVE disclosures, CISA Known Exploited Vulnerabilities, vendor advisories, and exploit intelligence.
• Determine whether emerging vulnerabilities affect organizational assets.
• Translate threat intelligence into exposure-management priorities.
• Map vulnerabilities and attack techniques to the MITRE ATT&CK framework.
• Provide actionable threat intelligence to SOC and Incident Response teams.

Adversary Simulation & Security Validation:

• Support authorized adversary emulation and purple-team exercises.
• Simulate realistic attacker behaviors to validate security controls.
• Test preventative and detective controls against known adversary techniques.
• Identify security-control gaps and detection weaknesses.
• Work with SOC and Security Engineering teams to improve detection and prevention capabilities.
• Document lessons learned and develop recommendations for improving defensive controls.

Security Engineering Collaboration:

• Partner with Security Engineering to remediate validated security exposures.
• Work with Network Engineering to address segmentation and exposed-service risks.
• Collaborate with Identity teams to address excessive privileges, authentication weaknesses, and Active Directory exposures.
• Work with Cloud Security teams to identify cloud infrastructure and identity risks.
• Partner with Application Security teams on application and API vulnerabilities.
• Provide offensive-security expertise during architecture and security-control reviews.

Reporting & Documentation:

• Produce detailed penetration testing and exposure-management reports.
• Clearly document: Vulnerability Attack vector Evidence Exploitability Attack path Business impact Risk rating Remediation recommendation.
• Present technical findings to security and IT stakeholders.
• Translate highly technical offensive-security findings into business-oriented risk statements.
• Maintain testing procedures, methodologies, playbooks, and documentation.
