The posting
The Offensive Security Analyst on the Web Application & Fraud Testing team conducts threat-driven security testing of Vanguard's critical client-facing web applications. This role applies nascent adversarial TTPs to validate whether existing controls detect and prevent the fraud tradecraft currently emerging in the threat landscape. Findings from this work directly inform detection improvements and control remediation across the enterprise.
Core Responsibilities
- Beyond traditional application testing, this operator will help design and execute realistic scenarios that stress-test cyber fraud detection and response, and partner with defensive teams in exercises to validate that our controls fire when they should.
- Assesses the risk and business impact of identified findings, applying defensible severity ratings based on likelihood, exploitability, and exposure. Thinks critically about remediation guidance so that recommendations to partner teams are practical, proportionate to the risk, and address root cause rather than symptom.
- Fosters and supports junior talent through informal leadership and coaching. Mentors junior team members to improve their technical acumen.
- Applies emerging adversarial tradecraft against client facing web application infrastructure through rigorous control validation to improve reactive and proactive threat driven operations.
- Conducts penetration testing, vulnerability assessments and threat modeling. Evaluates risks and makes recommendations.
- Provides written assessments focused on threats, vulnerabilities, and technologies relevant to Vanguard Infrastructure.
- Leads with IT and business teams to ensure prompt and effective distribution of findings so incidents are effectively addressed. Provides department support to the business on enterprise-wide security initiatives and projects.
- Participates in special projects and performs other duties as assigned.
