In an era where budget constraints are ever-present and the threat landscape is constantly evolving, organisation must optimize their cybersecurity spending with precision. This technical presentation delves into the integration of Cyber Threat Intelligence (CTI) within detection engineering frameworks to maximize the effectiveness of limited cybersecurity resources. The presentation will explore the strategic application of actionable intelligence to tailor defensive measures, enabling organisations to prioritize their security efforts based on tangible and relevant threat insights into adversary tactics, techniques, and procedures (TTPs). Attendees will gain a deeper understanding of how to interpret threat actor telemetry to engineer more robust targeted defenses and identify the most pertinent threats to their operations. This session offers a comprehensive guide to deploying a targeted cybersecurity strategy that not only mitigates cyber risks but also enhances the protection of critical assets within resource-constrained environments.
