Connect to your opportunity
As a Cybersecurity Controls Testing Analyst supporting the Control Testing Program, you will help execute a structured controls assurance model that validates the design and operating effectiveness of security controls through automated and manual control testing, effectiveness-based testing, and drives identified gaps through to remediation and closure.
You will work closely with the Cyber Compliance Manager and technical stakeholders across the organisation to deliver well-evidenced control assessments, validate remediation submitted by risk and control owners, and support the program’s wider reporting and governance activities. The role suits someone who is comfortable moving between hands-on technical testing, structured documentation, and proactive stakeholder follow-up.
Key Responsibilities
- Support execution of the Control Testing Program, including automated control testing (e.g. identifying tool integration opportunities and mapping source systems so they can provide continuous automated results), alongside manual, effectiveness-based testing of security controls.
- Maintain and update the control testing framework, including control-to-standard mappings, technical test queries, policy configuration checks, and clearly defined pass/fail criteria.
- Perform control testing across identity, endpoint, network, and infrastructure-based controls, including evidence collection, validation, and documentation.
- Apply risk management experience to understand how tested controls contribute to risk reduction, assess the impact of control gaps, and support risk-based prioritisation of remediation activities.
- Perform compliance validation of risk remediation activities submitted by risk and control owners, assessing whether the evidence provided adequately closes the identified gap.
- Follow up proactively with risk and control owners on outstanding remediation activities, tracking progress through to closure and escalating overdue items where required.
- Identify, track, and report control gaps, risks, and non-compliance issues to stakeholders, and support the development of remediation recommendations.
- Maintain ServiceNow (or an equivalent GRC/ITSM platform) workflows for remediation tracking and control lifecycle management.
- Collaborate with cross-functional technical and compliance stakeholders to ensure testing is consistent, well-evidenced, and aligned to industry standards (e.g., ISO 27001, NIST SP 800-53, CIS Controls, SOC 2).
- Support the Compliance Manager in preparing testing updates, KPI and dashboard inputs, and reporting materials for senior leadership, and contribute to standardised testing templates and methodologies.
- Stay current on control testing methodologies, regulatory developments, and industry best practices to inform testing priorities.

Regulation and controls are standard practice in our industry and Deloitte is no exception. These controls provide important legal protection for both you and the firm. We are subject to a number of audit regulations, one of which requires that certain colleagues abide by specific personal independence constraints (e.g., in relation to any financial interests and employment relationships). This can mean that you and your "Immediate Family Members" are not permitted to hold certain financial interests (shares, funds, bonds etc.) with audit clients of the firm, and also prohibitions on certain employment relationships (e.g., you are not permitted to hold a secondary employment role with SEC audit clients of the firm whilst being employed by the firm).
