CYSIAM Threat Hunting is a managed, proactive security service focused on identifying and mitigating persistent threats and sophisticated cyber-attacks that evade traditional detection tools. The service operates by building a threat model of the client's organisation and sector, then using technical threat intelligence to hypothesise how potential attacks would manifest on the network. Skilled analysts then conduct structured investigations — referred to as "hunts" — based on those hypotheses. Detection is behaviour-based, targeting Tactics, Techniques, and Procedures (TTPs) used by advanced threat actors rather than relying on signature-based methods. This approach is designed to surface threats that standard monitoring tools would not detect. Threat hunting at CYSIAM is a continuous, ongoing process rather than a point-in-time engagement. It is integrated with CYSIAM's Cyber Threat Intelligence (CTI) team and supported by a 24x7 UK-based Security Operations Centre (SOC). Key outcomes include: - Early detection of threats, reducing potential damage - Faster response to emerging incidents - Improved overall security posture - Reduced downtime and financial impact from cyber-attacks The service is available as part of CYSIAM's broader Managed Detection & Response (MDR) offering. CYSIAM holds CREST SOC accreditation and NCSC Cyber Incident Response Level 2 status, and is a CrowdStrike partner.
