Expertise across cyber security

Cyber security covers distinct disciplines across assurance, risk, controls, identity, vulnerability management and compliance. Rullion recruits experienced professionals who protect systems and help organisations evidence that security remains effective as technology and threats change.

Cyber Assurance

Confidence in security depends on being able to evidence that controls work as intended. Rullion currently supports assurance leadership across audits, risk assessments, control implementation and mitigation activity within the Nuclear sector, where governance and regulatory scrutiny are particularly high.

Cyber Risk & Governance

Turning technical risk into clear organisational decisions requires more than security knowledge alone. Roles can span risk assessments, security plans, policy, standards and oversight, helping teams understand which controls matter, how they should be governed and where regulatory requirements affect delivery.

Security Engineering & Controls

Protecting systems in practice means implementing and maintaining the right technical controls. Requirements can span identity, networking, Windows security, firewalls, hardening and wider protection measures across on-premise and Cloud Infrastructure, with the exact stack shaped by the client environment.

Identity & Access

Controlling who and what can access technology environments is central to reducing unnecessary exposure. Identity roles can include access management, governance and cloud identity platforms, often working closely with infrastructure, security and operational teams across complex organisations

Vulnerability Management

Finding weaknesses is only useful when organisations can prioritise and act on them. Vulnerability roles combine technical assessment with risk judgement, remediation planning and stakeholder communication, helping teams focus effort where exposure and operational impact are greatest.

Security Audit & Compliance

Evidence, standards and controls need to stand up to scrutiny. Rullion requirements have included ISO 27001, COBIT, privacy and regulatory obligations, with audit findings communicated across technical teams and management. Wider assurance needs can also connect with Background Screening and workforce compliance.

Cyber Leadership

Setting cyber direction means balancing emerging threats with regulation, business priorities and operational reality. Senior leaders oversee assurance, risk, controls and security operations while shaping long-term capability. For director and senior leadership appointments, explore Executive Search.

Security Readiness

Ready for regulated cyber environments

Cyber roles are shaped by the systems, threats, controls and regulatory environment behind them. Technical knowledge matters, but so do assurance, judgement and the ability to communicate risk clearly.

Assurance & Risk

Current Rullion cyber requirements include risk assessments, risk management plans, security audits and assurance of control implementation. We look at how candidates have assessed threats and vulnerabilities, challenged evidence and translated findings into practical action. That matters in regulated organisations where cyber assurance is not a one-off exercise but part of the system lifecycle.

Security Controls

Current cyber work spans Azure identity and networking, Windows security controls, firewalls, hardening, testing and vulnerability management. The exact technology changes by environment, so we use tools and controls as part of the brief rather than the whole assessment. Strong candidates also need to understand how controls are selected, implemented, maintained and evidenced.

Regulated Context

Cyber professionals in critical infrastructure may work within formal governance, legal, privacy and security requirements that affect every technical decision. Current Rullion requirements include regulated nuclear experience and standards such as ISO 27001. We consider whether candidates understand how security risk, audit findings and controls operate when accountability and assurance must be visible to both technical and non-technical stakeholders.

Why Rullion

Cyber recruitment grounded in assurance

Cyber security recruitment needs context behind the job title. Rullion considers the systems, security controls, assurance responsibilities, regulatory environment and stakeholders around the vacancy, helping clients distinguish essential security experience from capability that can transfer.

Live regulated cyber experience

Current Rullion recruitment includes a Cyber Assurance Lead supporting a major nuclear programme, covering audits, cyber risk, control implementation, privacy and regulated security requirements. That live work keeps our understanding connected to real critical infrastructure environments.

Risk and controls understood

Assurance, engineering, governance and vulnerability roles solve different parts of the security problem. Our briefs look at where responsibility sits, from assessing risk and challenging evidence to implementing controls, rather than treating every cyber vacancy as interchangeable.

Technical depth with stakeholders

Cyber professionals often need to explain technical findings to managers, operational teams and wider stakeholders. We consider whether candidates can communicate risk and mitigations clearly as well as understand the controls, standards or technologies behind them.

Experience can transfer

Strong cyber capability can move between sectors when the technology and risk environment are comparable. Direct experience matters more where national security, regulation, operational technology or specialist assurance requirements materially change how cyber security is governed.

Workforce support beyond recruitment

Cyber demand can sit within a wider technology transformation, creating connected needs across cloud, infrastructure, data and software. Rullion can support permanent and contract hiring, MSP delivery and Statement of Work where the requirement broadens beyond a single vacancy.

What is influencing cyber security recruitment?

Cyber hiring is shaped by changing threats, regulation and technology rather than one fixed skills list. Demand can move between assurance, controls, identity, cloud security and vulnerability management as organisations modernise systems and strengthen governance.

Assurance follows the lifecycle

Security assurance continues after implementation. Controls, risks and system use change over time, creating demand for professionals who can assess evidence, audit controls and help organisations maintain confidence as environments evolve.

Cloud changes security boundaries

Cloud adoption changes how identity, networking and controls are designed and operated. Current Rullion cyber requirements include Azure environments, showing why cloud knowledge increasingly sits alongside wider assurance and risk capability.

Regulation shapes the brief

Legal, privacy and sector requirements can materially change cyber responsibilities. Employers need to be clear where direct regulated-environment experience is essential and where strong security capability can transfer from another complex organisation.

Risk must be communicated

Technical findings only create value when stakeholders understand the consequence and required action. Cyber Security professionals who can explain risk, assurance gaps and mitigations clearly are important where decisions involve both technical teams and senior management.

Controls need ownership

Security controls move from design into implementation, operation and maintenance. Hiring briefs become stronger when organisations define whether the role is assessing controls, engineering them or owning assurance across the lifecycle.

Projects we’ve supported

Rullion supports technology recruitment in complex, regulated environments where cyber assurance, security controls and operational resilience sit close to wider digital and infrastructure delivery.
