  • Work across global business and technology teams to build awareness of security initiatives, present recommendations to stakeholders, champion security strategy, and drive organization-wide adoption to reduce risk and improve security posture.
  • Analyze the Information Security program’s operational effectiveness, processes, and stakeholder feedback; identify improvements and optimize processes to increase program effectiveness and agility.
  • Monitor and evaluate emerging security technologies, industry trends, and evolving threats; assess their potential impact on the firm and adapt the security strategy accordingly.
  • Identify strategic opportunities for innovation within the security program and plan and propose research initiatives or pilot projects for security solutions, architectures, or processes, including business cases for new investments or approaches.
  • Partner with Information Security, Enterprise Technology, and Client Technology teams to address security and business needs as new capabilities are conceived and adopted.
  • Prepare and present high-level analyses, strategic plans, and roadmaps to executive leadership, supporting executive decisions with clear recommendations, data-driven insights, and projections.
  • Serve as an information security subject matter expert; maintain knowledge of the firm’s technology portfolio, security architecture, and business operations, and educate business units on the program’s strategic direction.

US oil producers hit record output as capital spending drops 49% and reserve replacement falls

An Ernst & Young study found US oil and gas producers reached record production in 2025 while becoming more selective with investments. The analysis of 30 major exploration and production companies, representing 43% of US oil and gas output, showed oil production hit a study-period high, yet reserve additions from extensions and discoveries declined 11% year over year and failed to fully replace production volumes for the first time since 2021. Total capital expenditures fell 49% year over year, whilst M&A spending declined 70%. Exploration spending dropped 11% to $4.8 billion, representing only 3% of total capital expenditures. Natural gas showed stronger fundamentals, with production rising 18%, reserves increasing 14%, and discoveries up 21%.

EY commits $100M to bonuses rewarding human skills alongside AI adoption

Ernst & Young's US division is allocating $100 million this fiscal year to bonus payments rewarding employees who demonstrate adaptability, innovation, and judgement. Individual spot awards reach $500, whilst employees or teams making significant contributions can receive between $10,000 and $25,000, five times the previous programme's ceiling. The initiative also covers AI experimentation. "What we recognise signals what we value," said Ginnie Carlier, chief talent and culture officer for EY Americas. The bonuses form part of a broader strategy to reshape employee development across all career levels. Other professional services firms are pursuing similar approaches. KPMG restructured its audit internship this summer to emphasise critical thinking, whilst PwC US introduced training combining AI proficiency with human qualities like empathy. EY reported AI-related revenue grew 30% year-over-year in 2025.
