Pentest People is a UK-based security consultancy specialising in providing Penetration Testing as a Service to all its clients. Our innovative approach to security testing merges the benefits of consultant-led penetration testing with ongoing vulnerability assurance through our advanced SecurePortal. This provides clients with a continuous, living threat management system throughout the duration of the contract, rather than a single point-in-time assessment.
We are expanding our Incident Response team and are looking for a DFIR Consultant to join us in tackling some of the most challenging cybersecurity threats. This role requires strong analytical thinking, excellent problem-solving skills, and the ability to perform in a fast-paced environment.
As part of our dynamic team, you’ll play a critical role in mitigating cyberattacks and enhancing our clients’ security posture to prevent future incidents.

TECHNICAL SKILLS:

• Experience in incident response and investigation using tools like SIEM, SOAR, and EDR platforms.
• Proficiency in digital forensics and log analysis across Networking, Windows, Mac, Linux, or Cloud environments.
• Strong understanding of evidence collection and prioritisation procedures.
• In-depth knowledge of NIST 800-61 incident response lifecycle, including containment, eradication, and recovery.
• Experience in digital forensics, including evidence acquisition and chain-of-custody practices.
• Familiarity with frameworks such as MITRE ATTACK, Lockheed Martin Kill Chain, or the Diamond Model.
• Ability to perform dynamic malware analysis.
• Knowledge of open-source IR tools such as Velociraptor, Eric Zimmerman Tools, Chainsaw, Volatility, SOF-ELK, or DFIR-IRIS is preferred.

DESIRABLE QUALIFICATIONS:

• Industry certifications such as ECIH, Security+, BTL1, CySA+, or SC-200 are a plus.

ABOUT YOU

• Experienced in managing stakeholders during live incidents to minimise disruption.
• Strong communication skills with the ability to stay calm and effective under pressure.
• Able to align client deliverables with industry best practices.
• Skilled in proactive threat intelligence and analysis to support IR operations.
• Proactive, responsible, and eager to contribute to the growth of the Incident Response team.
  While this role is advertised as remote, it will require occasional visits to client sites and the office as needed. Candidates must be based in the UK and have the right to work, as we are unable to provide sponsorship at this time. If you do not have SC eligibility, you must meet the requirements for SC, as this may be a necessary criterion.
  We understand that job descriptions offer only a glimpse of the role. For more details, please feel free to reach out or apply, and we will be happy to provide additional information. Pentest People is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
