Challenges of Cyber Security: What Businesses Face and How to Overcome Them

The challenges of cyber security facing UK businesses in 2026 include a genuine regulatory gap: the new Cyber Security and Resilience Bill won’t cover the two most damaging attacks the country saw in 2025. Marks & Spencer and Jaguar Land Rover, whose breach alone cost the UK economy an estimated £1.9 billion, both sit outside the bill’s current scope.

Why Cyber Security Challenges Are Growing

Challenges of cyber security are intensifying because attack speed, sophistication, and regulatory complexity are all rising simultaneously, and NCSC’s 2025 Annual Review confirmed a 50% increase in highly significant incidents for the third consecutive year running.

The Biggest Cyber Security Problems and Solutions for Businesses

Ransomware and Double Extortion

Encryption is no longer guaranteed in ransomware attacks, appearing in just 78% of extortion cases in 2025, down sharply from over 90% previously, as attackers increasingly rely on stolen-data exposure threats alone rather than encrypting systems at all.

AI-Driven and AI-Powered Attacks

AI-driven attacks now automate reconnaissance, phishing, and extortion simultaneously, compressing the fastest intrusions from initial access to data exfiltration down to roughly 72 minutes.

Cloud Security Misconfigurations

Over 90% of breaches investigated in recent research were enabled by misconfigurations, not novel exploits, and analysis of 680,000-plus cloud identities found 99% carried excessive, often unused permissions.

Phishing and Social Engineering

The global average Phish-Prone Percentage before training sits at 33.2%, meaning roughly one in three employees would click a real phishing link with no defense in place.

Insider Threats

Negligent, not malicious, insiders drive the majority of insider risk cost, with average annual insider risk expense reaching $19.5 million across surveyed organizations in 2026.

Supply Chain Attacks

Third-party applications factored into 23% of investigated incidents, and a documented March 2026 case showed a compromised CI/CD tool used by 10,000-plus pipelines cascading to a second tool within 96 hours.

The Cyber Security Skills Gap

The global cybersecurity workforce gap sits at 4.8 million unfilled positions, forcing stretched teams into reactive, episodic work rather than sustained, proactive defense.

Emerging Threats in Cyber Security to Watch

Emerging threats in cyber security worth prioritizing include AI-orchestrated multi-vector campaigns coordinating timing across attack types simultaneously, and prompt injection against AI tooling, currently the top-ranked risk in the OWASP LLM Top 10.

Why These Challenges Hit Small and Mid-Sized Businesses Hardest

Small businesses face 43% of all cyberattacks despite limited security resources, and 60% of small businesses that suffer a major cyberattack close within six months, a survival risk larger enterprises simply don’t face at the same scale. Notably, the UK’s new resilience bill focuses narrowly on critical national infrastructure sectors, meaning most SMBs remain entirely outside its protective scope regardless of how damaging an individual attack might be to their own survival.

How to Conduct a Cyber Security Risk Assessment

1. Identify and Prioritise Assets

List systems and data by genuine business value, not exhaustively, since a focused list gets protected effectively while a sprawling one doesn’t.

2. Identify Threats and Vulnerabilities

Map realistic threats against each prioritized asset, drawing on documented attacker behavior rather than generic, unfocused concern.

3. Assess Likelihood and Impact

Score each identified risk by how likely it is and how much damage it would cause, producing a genuinely prioritized list rather than an undifferentiated one.

4. Prioritise and Remediate

Address highest likelihood-and-impact risks first, matching remediation effort to actual exposure rather than ease of implementation alone.

5. Monitor and Reassess Regularly

Risk assessments go stale fast; reassess at least annually and after any significant environment change.

How to Overcome Cyber Security Challenges: A Practical Framework

Overcoming these challenges means matching response to root cause specifically: MFA and access review for excessive permissions, continuous awareness training for phishing, tested backups for ransomware, and honest cyber security risk assessment repeated regularly rather than treated as a one-time exercise nobody revisits.

US Regulatory Landscape: NIST, CISA and Reporting

US businesses navigate NIST CSF 2.0 alongside CISA’s Cross-Sector Cybersecurity Performance Goals, a prioritized, high-impact subset specifically designed as an achievable starting point for organizations without a critical-infrastructure-scale compliance program.

UK Regulatory Landscape: NCSC, the Cyber Security and Resilience Bill and Cyber Essentials

The Cyber Security and Resilience Bill, progressing through Parliament with expected Royal Assent in 2026, brings managed service providers and data centres into scope, requiring incident notification to both the regulator and NCSC within 24 hours, followed by a full report within 72. Penalties for serious breaches reach £17 million or 4% of global turnover. Alongside the bill, the government’s Cyber Governance Code of Practice gives board members direct guidance, and Cyber Essentials, five basic technical controls, remains the recommended baseline for businesses of every size, regardless of whether the new bill’s narrower critical-sector scope currently applies to them.
