Building a culture of vigilance in an evolving threat landscape

We spoke to Angela Vernon-Lawson, a Chartered Security Professional with more than 20 years of global experience across operational delivery and academia, about how organisations can respond to today’s risks, and what learners take away from the CTPSaP qualification.

Understanding today’s threat landscape

Over the course of her career, Angela has seen a significant shift in both the nature and complexity of threats facing organisations.

Threats are no longer predictable or confined to one domain. Instead, organisations must now contend with a combination of physical and cyber risks, often amplified by technological advances such as automation, AI, and increasingly sophisticated attack methods.

At the same time, ways of working have evolved. Hybrid working, cloud-based systems, and interconnected environments have expanded the potential attack surface, making it more important than ever for organisations to stay informed and prepared.

“The threat landscape has become more sophisticated and unpredictable. Organisations need to invest not only in solutions, but in their people and their overall security strategies,” Angela says.

From frontline to first line of defence

One of the most significant changes Angela highlights is the growing importance of frontline personnel.

Where security was once seen as a specialist function, today it is – or at least should be – embedded across organisations. Staff working in operational and public-facing roles are often best placed to notice unusual activity, identify vulnerabilities, report anomalies, and respond in the early stages of an incident.

This shift requires a new level of awareness, accountability, and communication.

“Frontline personnel are now central to security operations. Their ability to observe, question, and report is critical in identifying potential risks early,” Angela points out.

But awareness alone isn’t enough; it must be supported by robust planning and regular testing.

“Testing of emergency and business continuity plans is crucial for organisations to be prepared to protect not only the business, but also the wider community.”

Why organisations struggle to put protective security principles into practice

While many organisations understand the importance of protective security, translating that understanding into day-to-day practice remains a common challenge.

Angela points to several recurring issues:

• Security processes that are overly complex or poorly communicated
• Difficulty embedding security into daily operations
• A gradual loss of vigilance over time due to complacency or lack of ongoing training

Even where governance structures exist, they don’t always guarantee effective implementation without strong oversight and engagement at all levels. The result can be gaps between strategy and execution – where policies exist on paper but are not consistently applied in reality.

Making security a shared responsibility

A key theme in Angela’s methodology is the idea that protective security must be owned by the whole organisation, not just a single team or function.

In practice, this means:

• Encouraging collaboration between leadership and operational staff
• Creating a collaborative culture of transparency and information sharing
• Clearly defining roles and responsibilities
• Providing accessible and relevant training

When organisations take this approach, security becomes part of everyday thinking rather than a standalone requirement.

“Protective security is strongest when organisations embed a culture of strategic teamwork and take a joined-up approach to security governance. Reinforced through training and awareness, this enables a deeper understanding of threats and more effective, coordinated responses,” says Angela.

A mindset for the future

Angela’s most important takeaway from the qualification isn’t just knowledge; it’s mindset.

Rather than seeing training as a one-off exercise, she encourages learners to adopt a mindset of continuous development:

“This qualification should be seen as a gateway to ongoing learning – staying curious, adapting to change, and continually strengthening your understanding of good practice.”

This mindset not only supports professional growth but also contributes to safer organisations and communities in an ever-changing world.
