Open Source Intelligence (OSINT) has evolved into a critical pillar of proactive cyber defence, enabling organisations to detect, analyse, and respond to emerging threats before they materialise. By leveraging publicly available information from diverse digital environments (including the dark web, social media, and technical repositories) predictive OSINT empowers cyber intelligence teams to anticipate attack patterns, identify vulnerabilities, and mitigate risks in real time. This approach not only strengthens security postures but also provides a decisive competitive advantage, allowing entities to stay ahead of adversaries in an increasingly complex and volatile threat landscape.
