If the buzzword for 2024 was resilience, 2025's is collaboration. In a world of political turbulence, constant technological innovation and ever more complex threats, sharing data, threat intelligence, experience, knowledge and expertise becomes even more important. Organisations are now interdependent and reliant on capability provided by third parties. Supply chains are critical to an organisation's ability to operate, and attacks are often indiscriminate in what and where they harm. Protecting ourselves is often not enough when our suppliers may well provide the access point through our defences, particularly if they lack the capacity or knowledge to protect themselves. Collaboration is, however, easier said than done. It thrives on trust and strong relationships and requires constant investment in time and effort ' rather like resilience.
