Rebecca Harness, Chief Information Security Officer, Deltek, discusses how organisations must evolve their security strategy in line with emerging cybersecurity threats.

A company’s cybersecurity strategy is often compared to a chain – only as strong as its weakest link.

Yet in my experience leading security teams, this has proven far from the truth.

As digital transformation continues at pace, this has become much more like a web, with threads weaving between departments, functions and countries, binding every aspect of digital defence.

When these threads weaken, even the most sophisticated security technologies can unravel.

Long gone are the days when digital security could be delegated solely to technical specialists.

Today, every individual within an organisation, from front-desk personnel to executive leadership, bears responsibility for maintaining cyber defences.

As threat actors deploy increasingly sophisticated methods, organisations must evolve their security strategy accordingly, ensuring their protective measures match the complexity of modern attacks.

Research indicates that while CEOs understand cybersecurity protocols, almost three in four feel uncomfortable making cyber-related decisions.

This troubling disconnect highlights the urgent need for security leaders to strengthen organisational understanding and establish robust security practices across all levels of operations.

As we approach 2025, fostering a security-first mindset from the top down becomes paramount.

This cultural transformation extends beyond implementing new security policies—it requires embedding cyber awareness into the fabric of everyday business operations.

When chief information security officers champion this comprehensive approach, organisations develop the resilience needed to face tomorrow’s digital challenges.

The evolution of cyber defences in the digital age

Today’s digital landscape offers unprecedented opportunities for innovation and growth.

However, this transformation introduces new vulnerabilities that organisations must actively address.

Each cloud-based service, connected device, and digital touchpoint represent a potential gateway for cyber criminals to exploit.

Our own Clarity report revealed that 31% of organisations encountered significant cybersecurity incidents in 2023, emphasising the pressing reality of digital threats.

Moreover, with artificial intelligence (AI) rapidly integrating into business processes, security strategies require constant refinement to maintain effectiveness.

The financial impact of these incidents cannot be understated.

Recent data suggests that the average cost of a data breach for UK businesses has risen to £4.2 million, highlighting the critical importance of proactive security measures.

Beyond immediate financial losses, organisations face lasting reputational damage, regulatory scrutiny, and diminished customer trust.

Security leaders must spearhead initiatives that cultivate organisation-wide cyber awareness.

This involves implementing comprehensive training programmes, conducting regular threat simulations and establishing clear channels for security-related communication.

By integrating security considerations into performance evaluations and fostering an environment where employees feel empowered to report potential threats, organisations can build a truly resilient security culture.

These initiatives must be supported with robust incident response planning.

History tells us that organisations with well-rehearsed incident response plans recover from security incidents much faster than those without such preparations.

Regular tabletop exercises and scenario planning help teams develop muscle memory for crisis situations, ensuring swift and effective responses when real incidents occur.

Juggling innovation with vigilance

The emergence of AI technologies presents both opportunities and challenges in the cybersecurity landscape.

Whilst AI offers powerful capabilities for threat detection and response, it also provides new tools for malicious actors.

Organisations must carefully balance the adoption of innovative security solutions whilst remaining vigilant against evolving threats.

AI’s capability to process vast quantities of security data and identify subtle patterns proves invaluable in modern cyber defence.

However, the human element remains crucial—security professionals provide essential context, strategic insight, and ethical oversight that technology alone cannot deliver.

The most effective security programmes combine advanced AI capabilities with human expertise, creating a comprehensive defence system that adapts to emerging threats whilst maintaining practical usability.

The integration of AI into security operations has shown remarkable results.

Organisations implementing AI-driven security solutions consistently report significant improvements in threat detection speed and substantial reductions in false positives compared to traditional systems.

These improvements allow security teams to focus their expertise on complex challenges that require human judgment and strategic thinking.

However, the adoption of AI in security operations brings its own set of challenges. Security teams must ensure AI systems are properly trained, regularly updated and carefully monitored to prevent bias or manipulation.

Additionally, organisations must maintain transparency about their use of AI in security operations, particularly when handling sensitive data or making automated security decisions.

Building a culture of continuous improvement

Success in today’s landscape relies on more than just technological solutions.

Organisations must re-evaluate how they view and prioritise security.

Regular security awareness training, clear communication channels, and visible executive support all play crucial roles in building this culture.

When properly implemented, robust cybersecurity transforms from a necessary expense into a strategic advantage.

The journey toward a truly security-conscious organisation never truly ends.

It requires constant evaluation, adaptation, and improvement as new threats emerge and technology evolves.

However, organisations that successfully embed security into their cultural DNA will find themselves better equipped to face whatever challenges the future may bring.
