Rarely a day passes without a media story telling us about a computer system breach or ransomware attack, or some other cybercrime affecting a business.
On the plus side, for every cybercrime that succeeds, there will be hundreds of attempts that fail because of the robust cybersecurity measures and policies that businesses have in place to protect against potential threats.
But as technologies become more sophisticated, so too do the ways in which cybercriminals will try to gain sensitive information and hold businesses to ransom, whether it’s a phishing scam, or ransomware attack. Increasingly, cyber criminals are targeting infrastructure, like power networks, and public sector organisations like hospitals, causing widespread disruption to thousands of people.
So what cybersecurity best practices should businesses follow to protect their business operations and prevent reputational damage? Read on to find out more.
Five cyber threats facing businesses in 2025
Whether it’s data breaches or ransomware, cyber criminals are using increasingly sophisticated methods to gain unauthorized access to IT systems. Here are five evolving threats:
1. AI-Driven cyberattacks
Cybercriminals are likely to use artificial intelligence to create more advanced and adaptive malware, phishing schemes, and even autonomous attacks.
2. Exploitation of IoT devices
With the growing number of interconnected devices, the Internet of Things (IoT) presents a larger attack surface for cybercriminals to exploit.
3. Quantum computing threats
As quantum computing advances, traditional encryption methods may become vulnerable, prompting the need for quantum-resistant cryptography to ensure data protection.
4. Deepfake and synthetic media
Increasingly AI tools are being used to create fake media. Deepfake technology is being used to commit fraud and spread misinformation. Identity theft is expected to rise, as it becomes harder to distinguish between real and fake content.5.
5. Targeted ransomware
Ransomware attacks are likely to become more targeted, focusing on critical infrastructure, such as power stations and hospitals, and high-value organizations.
Staying ahead of cybercriminals
Information security is vital for UK businesses in today’s digital world, to protect sensitive data, avoid reputational damage and prevent financial losses. But with resources often limited, particularly in small businesses, what cybersecurity measures need to be in place to stay a step ahead of the hackers?
Adopt a zero trust model
Implementing a “trust no one, verify everything” approach will help to minimize unauthorized access and insider threats. Restrict access to sensitive systems and data based on roles and responsibilities, so only key stakeholders can gain access as needed.
Educate employees
Employee training on cybersecurity best practices and developing a culture of vigilance is vital. This will help staff to spot suspicious activity, such as phishing emails, and encourage them to maintain strong passwords. Human error, such as falling victim to a phishing attack, is a common cause for a security breach but regular training will ensure staff act as a first line defence against cyber attacks.
Implement multi-factor authentication (MFA)
Adding an extra layer of security for logins and regularly updating security patches can reduce cyber risks, making it harder for attackers to gain access.
Keep software updated
Regularly update systems and software to patch vulnerabilities that cybercriminals exploit and reduce security risks.
Use strong firewalls and antivirus software
With remote work being ever more popular, protecting your VPN networks and devices from unauthorized access and malware has never been more important. AI-powered tools can be used to monitor and identify vulnerabilities in real time.
Encrypt sensitive data
Always protect sensitive information, including customer data, with robust encryption to prevent unauthorized access.
Back up data
Regularly back up critical business data and store it securely, ensuring recovery in case of a ransomware attack.
Invest in cyber resilience
Develop a comprehensive incident response plan and conduct regular simulations to test your defences. Cyber insurance policies can also protect your business from financial losses linked to cybercrime.
Strengthen third-party risk management
Ensure that third-party suppliers and partners comply with cybersecurity standards to prevent breaches through external systems.
Develop and test an incident response plan
This will help your business respond to cyber incidents quickly and effectively.
The five ‘C’s of cybersecurity
Here are five guiding principles to create a robust security framework.
1. Change
Threats evolve constantly, and businesses must stay agile by updating systems, policies, and practices regularly.
2. Compliance
Adhering to legal and industry standards, such as GDPR will ensure your organization meets regulatory requirements and protects sensitive data appropriately.
3. Coverage
Comprehensive security measures should cover all areas, including networks, endpoints, applications, and data, leaving no weak spots for attackers to exploit.
4. Continuity
Planning for business continuity and disaster recovery ensures that operations can continue with minimal disruption, even after a cyber incident.
5. Culture
Fostering a security-conscious culture among employees can reduce human error and make cybersecurity a shared responsibility across the organization.
