The Cost of Doing Nothing: Why Cyber Security Inaction is the biggest risk of all

Cybersecurity is no longer something businesses can choose to ignore, or treat as a low priority. With more cyber-attacks happening every day and new rules about how companies must protect data, keeping systems safe has become a must-have part of running a business. Today, protecting digital information is just as important as managing finances or serving customers.

This article explores why cybersecurity has transitioned from a discretionary line item to a critical operating cost that businesses must prioritise.

The financial impact of cyberattacks on major retailers

In recent years, the financial devastation caused by cyberattacks has been both real and immediate. The April 2025 ransomware attacks on major UK retailers serve as a stark reminder. Marks & Spencer (M&S), one of the most high-profile victims, saw nearly £300 million wiped out in profits and over £1 billion erased in market value. This wasn't just a hypothetical risk but a concrete blow that affected customers, shareholders, and operations.

The financial implications of such breaches extend far beyond immediate losses. They can lead to diminished investor confidence, increased insurance premiums, and long-term reputational damage. In today's interconnected digital landscape, a single cyberattack can unravel years of financial growth and stability.

Operational disruptions beyond IT

Cyberattacks are no longer confined to IT departments. They now cause widespread operational disruptions that can cripple entire businesses. For M&S, online services were down for nearly seven weeks, forcing the company to revert to manual processing and leaving shelves empty. Similarly, the Co-op had to switch to paper systems, impacting even its funeral division. These are not merely "tech problems"; they are full-scale business shutdowns.

Such disruptions highlight the intrinsic connection between digital and physical operations. When cyberattacks strike, they can halt supply chains, impede customer service, and erode operational efficiency. This new reality underscores the need for comprehensive cybersecurity measures that protect all facets of a business, not just its digital assets.

The evolution of ransomware and double extortion tactics

Ransomware has evolved beyond simple file encryption. Modern ransomware groups employ double extortion tactics, where they first steal data before encrypting it and then threaten to leak it. This raises the stakes significantly, as organisations now face not only the risk of data loss but also the potential for brand damage and regulatory exposure.

The dual threat of encryption and data leakage means that businesses must prepare for multifaceted attacks. These incidents can lead to regulatory fines, class-action lawsuits, and irreparable harm to a company's reputation. Understanding the evolving tactics of cybercriminals is crucial for developing robust defences and mitigating the impact of attacks.

Why smaller businesses are also at risk

It's not just Fortune 500 companies that are targeted by cybercriminals. Businesses, such as Harrods, Co-op, and KNP, have all fallen victim to devastating cyberattacks. Attackers are not always chasing global mega-corporations; any organisation with valuable data and gaps in their defences is a viable target.

Smaller businesses often lack the resources and expertise to implement comprehensive cybersecurity measures, making them attractive targets for cybercriminals. However, the consequences of a cyberattack can be just as severe for these organisations, leading to operational disruptions, financial losses, and reputational damage. Investing in cybersecurity is essential for businesses of all sizes to protect their assets and ensure long-term viability.

The competitive advantage of proactive cybersecurity Investment

In today's business landscape, proactive investment in cybersecurity is not just a defensive measure; it is a competitive necessity. Customers, partners, and regulators are closely watching how organisations respond to cyber threats. Companies that invest in security proactively are better positioned to maintain trust, recover faster, and prevent existential financial damage.

A robust cybersecurity posture can differentiate a business from its competitors, demonstrating a commitment to protecting customer data and ensuring operational continuity. This trust can translate into customer loyalty, stronger partnerships, and a favourable reputation in the market. In an era where cyber threats are ubiquitous, proactive cybersecurity investment is a strategic advantage.

Recommendations for treating cybersecurity as a business essential

To treat cybersecurity as a business essential, akin to insurance, compliance, or legal frameworks, businesses should adopt the following recommendations:

• Conduct regular risk assessments: Identify vulnerabilities and assess the potential impact of cyber threats. Regular risk assessments help prioritise security investments and ensure that defences are aligned with the evolving threat landscape.

• Implement comprehensive security measures: Deploy a multi-layered security approach that includes firewalls, intrusion detection systems, encryption, and regular software updates. Ensure that both digital and physical operations are protected.

• Educate and train employees: Cybersecurity is a collective responsibility. Conduct regular training sessions to educate employees about phishing, social engineering, and other common attack vectors. Empower staff to recognise and respond to potential threats.

• Develop incident response plans: Prepare for the worst-case scenario by developing and regularly updating incident response plans. These plans should outline the steps to take in the event of a cyberattack, including communication strategies and recovery procedures.

• Collaborate with security experts: Engage with cybersecurity professionals to stay informed about the latest threats and best practices. Consider partnering with managed security service providers (MSSPs) to augment in-house capabilities.

• Monitor and adapt: Cyber threats are constantly evolving. Continuously monitor security systems, review policies, and adapt strategies to address new risks. Stay proactive and vigilant to maintain a strong security posture.
