The situation

The volume and sophistication of financial threats was rising. The bank needed hands-on capability in the SOC rotation, able to work at pace under real pressure.

What we did

  • Defined the profile with the bank's cyber security team around hands-on SIEM and EDR experience.
  • Drew on a specialised pool of certified security professionals with five or more years of experience.
  • Screened on incident playbooks, malware analysis and real-time log monitoring.
  • Fast-tracked the process to complete the 24/7 rotation.

What was delivered

  • Placed an analyst monitoring network traffic, investigating alerts and executing incident response protocols.
  • SIEM rules fine-tuned to cut noise and false positives.
  • Updated threat intelligence feeds integrated into the monitoring system.
  • Active participation in post-incident review to strengthen the bank's defensive posture.

What changed

Mean time to detect
Improved through optimised alert monitoring and triage.
False positives
Substantially reduced, freeing the senior team for high-priority investigation.
Triage accuracy
High-priority threats identified and escalated with greater speed and clarity.

Frequently Asked Questions

Screening covered hands-on SIEM and EDR experience, incident playbooks, malware analysis and real-time log monitoring. The profile was defined with the bank's own cyber security team, so the technical bar matched the tooling in the environment rather than a generic security specification. A security operations centre runs at pace under real pressure, so candidates were assessed on what they had done during live incidents.

Marquee drew on a specialised pool of certified security professionals with five or more years of experience. Certifications held included CEH and CompTIA Security+. Experience was weighed alongside the certification rather than behind it, since a security operations centre rewards judgement under time pressure. Candidates were screened on incident playbooks and malware analysis together, because both come into play during a live investigation.

Marquee fast-tracked this search to complete the bank's 24/7 security operations centre rotation. Searching begins within twelve hours of a signed brief, against an industry standard of 48 to 72 hours before a first list appears, and an agreed shortlist follows in about eight days. A rotation that runs around the clock carries a standing requirement for cover, so the brief was treated as urgent from the first conversation.

Mean time to detect improved through optimised alert monitoring and triage. False positives reduced substantially once SIEM rules were fine-tuned, which freed the senior security team for high-priority investigations. Updated threat intelligence feeds were integrated into the monitoring system, and high-priority threats were escalated to senior engineers with greater speed and clarity. The analyst also joined post-incident reviews to strengthen the bank's defensive posture.

Yes. Marquee runs permanent and fractional security mandates through the same evaluation. What changes is how long the person stays and where the contract sits. A permanent seat suits an open-ended position on the rotation. A fractional engagement suits a defined programme of work, such as a tooling migration or a compliance cycle. Marquee works on a contingent basis, so a fee falls due when a candidate joins.
