For years, cyber security has been treated as a defensive function inside organisations. A necessary cost. Something to avoid regulatory trouble or protect against breaches.
That view is starting to change.
Increasingly, organisations are discovering that strong cyber security leadership does more than reduce risk. It enables growth. From supply chain contracts to international expansion, the ability to demonstrate credible security governance is becoming a commercial requirement for many businesses.
Amy Lemberger, former FTSE-250 Chief Information Security Officer and founder of The CISO Hub, believes organisations are only just beginning to understand this shift.
“Cyber security used to be framed almost entirely as risk avoidance,” she says. “But what many leadership teams are realising now is that good security governance helps businesses move faster. It gives customers, regulators and partners confidence that you can operate safely.”
That confidence is increasingly influencing who organisations choose to work with.
Across sectors, large companies are tightening their expectations around cyber resilience within their supply chains. Businesses bidding for contracts are now routinely asked to demonstrate their security controls, governance structures and incident response capabilities.
For organisations without clear leadership in place, that scrutiny can quickly become a barrier.
“In many cases it’s not the technology that holds companies back,” Lemberger explains. “It’s the absence of someone senior who can explain how security is managed, how decisions are made, and how risks are governed.”
This is one of the reasons the role of the Chief Information Security Officer, or CISO, has evolved so rapidly in recent years. Traditionally seen as a technical leadership role, the CISO is increasingly expected to operate as a bridge between technology, regulation and business strategy.
They translate cyber risk into decisions that boards and executive teams can act on.
They also ensure organisations understand the implications of how they grow, particularly as digital infrastructure becomes more complex and more regulated.
“Security leadership today is not just about protecting systems,” Lemberger says. “It’s about helping businesses understand the trade-offs they’re making as they expand into new markets, launch new products, or adopt new technologies.”
This governance role is becoming more important as regulation expands across Europe and the UK.
Legislation such as the EU’s NIS2 directive and the forthcoming Cyber Resilience Act are increasing expectations around organisational responsibility for cyber risk. At the same time, sector regulators and supply chain partners are placing greater scrutiny on how companies manage security internally.
For mid-sized organisations, this shift creates a challenge.
They are large enough to face regulatory expectations and supply chain scrutiny. But many cannot justify the cost of hiring a full-time CISO or building a dedicated security leadership function.
The result is what many security professionals now describe as a leadership gap.
Businesses know cyber security matters. They often have the right tools in place. What they lack is the senior oversight needed to turn those tools into a coherent strategy.
This gap is one of the factors driving the rise of fractional or virtual CISO roles.
Instead of hiring a full-time executive, organisations bring in experienced security leaders on a part-time basis to help guide decision-making, governance and risk management.
The model allows companies to access senior expertise without the cost or complexity of building an in-house leadership team. Lemberger founded The CISO Hub in response to the growing demand for this type of leadership.
The platform connects organisations and service providers with experienced CISOs who operate fractionally across multiple companies.
“Many organisations don’t need a full-time CISO,” she says. “What they need is access to experienced leadership that can help them understand what good looks like and how to get there.”
According to Lemberger, the biggest shift happening in cyber security today is not technological. It is cultural. Boards and senior leaders are gradually recognising that security is not simply an IT responsibility. It is part of how modern organisations operate and grow.
“The businesses that are doing this well see security as an enabler,” she says. “They understand that if they can demonstrate strong governance and resilience, it opens doors rather than closing them.”
This is particularly true for companies working in technology, manufacturing, logistics and other sectors where digital systems underpin daily operations.
Customers increasingly want assurance that the organisations they work with take cyber risk seriously. That assurance often comes not from technology alone, but from leadership.
For many organisations, the question is no longer whether cyber security matters. It is whether they have the right level of leadership in place to manage it. As digital infrastructure becomes more central to how businesses operate, the ability to demonstrate credible security governance may become one of the defining characteristics of successful organisations.
“Security used to be something companies thought about after a problem,” Lemberger says. “Now it’s becoming something that helps them move forward with confidence.”
