The team provides the Board and Executive Management Team with independent insight into the security of our most important information, helping to inform security decisions at the highest levels of the business.
AE operations range from a few weeks to more than a year. Each engagement emulates different internal and external threat actors, testing a broad range of systems, processes and assumptions. The variety and complexity of this work creates continuous opportunities to tackle challenging problems, develop technical expertise and work as part of a highly collaborative team.

Researching threat actors, target environments and defensive controls to design realistic attack paths and operation-specific kill chains
Developing custom tooling, tradecraft and tactics, techniques and procedures (TTPs) to support offensive operations
Executing adversary emulation operations, contributing to operational decision-making and adapting approaches as new information emerges
Documenting and sharing technical knowledge, operational experience, OPSEC techniques and ways of working
Providing subject matter expertise on emerging cyber threats and offensive security techniques
Contributing to the continuous improvement of team tooling, processes and operational capabilities

Ability to make sound decisions and deliver results in ambiguous, fast-changing environments
Administrator-level experience in Windows 11 and Linux systems
