Our take

Traditional intelligence gathering often struggles to keep pace with the evolving nature of threats. Siloed approaches focus solely on physical or online risks and miss the complex interplay between the two, leaving organisations vulnerable.

ExTrac offers a comprehensive approach, with its system bridging the physical and online divide, providing real-time insights into a broad range of threats, including terrorism, violent extremism, disinformation, and crime. Its Co-Analyst tool allows even non-experts to obtain valuable insights and make faster, more informed decisions.

The company's innovative technology and focus on user-friendliness positions it to empower a wide range of organisations to proactively manage risk. As the threat landscape continues to evolve, ExTrac is poised for continued growth, with a wealth of opportunity on its horizon.
