Offensive Security Analyst

Within Information Security we blend risk strategy, digital identity, cyber defense, application security and technology solutions as we consider the entire security lifecycle. You will join a team of hardworking, security‑focused individuals dedicated to supporting, protecting and enabling the business through innovative, secure solutions that provide speed to market and business value.

As an Offensive Security Analyst on the Attack Surface Management team, you will play a key role in evaluating and reducing EY’s digital exposure through hands‑on penetration testing and adversarial simulation. Working under the guidance of the Exposure Management Lead, you will identify, assess and help mitigate vulnerabilities across EY’s global attack surface. This role goes beyond traditional scanning by actively emulating threat actors, performing penetration testing and assessing the true impact of security weaknesses.

Your responsibilities will include supporting the validation of third‑party risk assessments, identifying misconfigurations and exposed assets, and ensuring security standards are applied across EY’s digital ecosystem. You will also contribute to strengthening Continuous Threat Exposure Management and Attack Surface Management efforts by providing actionable insights that improve proactive defense and reduce overall business risk.

The Analyst will apply offensive security techniques to assess EY’s external and internal attack surface, identifying vulnerabilities across web applications, APIs, cloud environments, networks, and infrastructure. This includes testing proof‑of‑concepts to validate exploitability and determine real‑world impact. The role involves emulating adversary tactics to test detection and response capabilities, as well as conducting reconnaissance and asset discovery to uncover unmanaged or exposed assets.

The candidate will support third‑party and supply chain risk validation efforts by reviewing assessments or conducting targeted testing where required. Collaborating closely with security engineering, blue teams, and business stakeholders, the analyst will help prioritize remediation efforts based on risk severity and exploitability. Additionally, the role will contribute to enhancing processes, playbooks, and reporting standards within the Vulnerability Discovery and offensive security functions.
