Operationalize Continuous Threat & Exposure Management (CTEM) across critical applications and business services

• Define CTEM scope around critical business services, crown-jewel applications, sensitive data, material APIs, and externally exposed assets.
• Consolidate exposure signals from application testing, attack-surface management, cloud security, vulnerability management, penetration testing, bug bounty, and threat intelligence.
• Establish a common exposure taxonomy and risk model that incorporates exploitability, reachability, business criticality, threat activity, and compensating controls.
• Maintain an evidence-backed view of application exposure rather than relying primarily on scanner severity.

Cloud & Modern Architecture Security
Provide application security guidance for:

• Cloud-native applications

• Microservices

• APIs

• Containers

• Kubernetes

• Serverless architectures

• Artificial Intelligence and Machine Learning applications

• Third-party integrations

  • Application vulnerability management

• Possesses at least one of the following certifications (o4 comparable alternative):

  • CISSP

  • CSSLP

  • GIAC Secure Software Programmer (GSSP)

  • GIAC Cloud Security Automation (GCSA)

What Success Looks Like:
Within the first 12–18 months, this leader will

• Complete a comprehensive assessment of the organization's Application Security maturity.

• Develop and execute a multi-year Application Security transformation roadmap.

• Fully integrate security into CI/CD pipelines across major engineering organizations.

• Implement meaningful risk-based application security metrics and executive dashboards.

• Reduce application vulnerability remediation times while improving engineering satisfaction.

• Standardize threat modeling, secure code review, and security testing practices.

• Develop measurable improvements in software security posture without negatively impacting developer productivity.
