CIRT Analyst

Cyber Security Analyst (Contract)
Location: Cheltenham (Ideally 1 day per week onsite)
Contract: 6 Months
Rate: £300 per day (Inside IR35)

The Opportunity Our client, a leading organisation, is looking for an experienced Cyber Security Analyst to join a high-profile programme on an initial six-month contract.

This role is heavily focused on technical application security assessments, supporting a major project by reviewing a large volume of applications and ensuring they meet security standards before deployment. Whilst there is some exposure to Cyber Incident Response activities, this is very much a hands-on security assessment role where you'll be expected to work independently and manage a consistent technical workload.

What you'll be doing

• Assess approximately 300 applications from a technical security perspective.
• Build, configure and manage virtual machines within VMware to support application testing.
• Execute security scans against executables and installation packages.
• Identify vulnerabilities and provide clear remediation recommendations.
• Use vulnerability management tools such as Qualys (or similar) to assess security risks.
• Support ongoing cybersecurity project delivery within a high-profile programme.
• Assist with Cyber Incident Response activities where required, including security monitoring and investigation.

What we're looking for We're looking for someone who can hit the ground running with experience in:

• VMware virtual machine creation and management.
• Application and executable security testing.
• Vulnerability assessment and remediation.
• Qualys or comparable vulnerability management tooling.
• Working independently with minimal supervision.
• Strong technical judgement and attention to detail.
• Experience within cybersecurity, infrastructure or security operations environments.

Desirable experience includes:

• Microsoft Defender or Microsoft Sentinel.
• SOC or CIRT environments.
• Incident response or security monitoring.
• PowerShell or Python scripting.
• Knowledge of MITRE ATT&CK or security frameworks.

Why apply?

• Immediate start on a high-profile security programme.
• Flexible hybrid working.
• Long-term project with meaningful technical work.
• Opportunity to support both project delivery and incident response.
• £300 per day (Inside IR35).

If you're an experienced Cyber Security professional with strong vulnerability assessment experience and are available for your next contract, we'd love to hear from you.
