Marie Diane Tyler brings influence through advocacy, communications and representation within the security sector. As Co-founder of Girls Who Dare, she is involved in training designed to strengthen resilience, performance and confidence by combining experience from the security industry, corporate strategy, and hostage negotiation. Her wider work with IPSA also places her close to conversations around professional opportunity, visibility and leadership for people who may not always see a clear route into the sector.
With more than 20 years’ experience in the global security industry, Tyler’s background includes strategic business leadership, marketing, events and industry communication. That experience gives her a strong understanding of how security presents itself, attracts talent and builds professional confidence.
Supporting women in industry
Tyler’s contribution is especially visible through the Women in Industry podcast, powered by OrangeDoor, recorded at The Security Event 2026 in partnership with IPSA and DARE. The series has created a platform for women across the industry to discuss their journeys, challenges and impact, bringing conversations about representation and career progression into a public setting.
Her work is important because influence in security is not only technical or operational; it is also cultural. The sector needs people who can communicate its value, open up participation and make leadership feel more accessible to those entering or progressing within the profession. Tyler’s work supports a more confident, visible and representative security industry, while helping to show that communication, mentorship and inclusion are practical tools for strengthening the sector’s future workforce.
