What is Cyber-security?

Cyber-security is the practice of protecting computers, servers, mobile devices, electronic systems, networks, and data from digital attacks, theft, and damage. These attacks can come in the form of viruses, worms, Trojan horses, ransomware, spyware, and other types of malware, as well as phishing scams and other forms of cybercrime.

Why Small Businesses?

Cybercriminals target small businesses because they often have fewer security measures than larger organisations. Limited resources and IT personnel make recovery from attacks particularly challenging, potentially causing devastating financial losses and reputation damage.

Legal & Compliance Risks

If your business handles sensitive customer data—financial records, personal information—inadequate security can result in data breaches, GDPR violations, legal liability, and voided insurance policies. Cyber insurance requires proper security measures.

Your Protection Strategy

Don't leave your data and business assets at risk. We provide cutting-edge technology and expert talent to protect you from both external threats and insider risks. Cyberattacks don't discriminate by company size—proper protection is essential.

Protecting Your Business from Cyber-attacks

Strong Password Management

Use unique, complex passwords for all accounts with a password manager. Enable two-factor authentication for an extra security layer.

Keep Systems Updated

Install security updates immediately when available. Keep all software and devices current to fix vulnerabilities before they're exploited.

Firewall Protection

Deploy enterprise-grade firewalls to protect your network from external threats by blocking unauthorised access attempts.

Anti-Malware Defence

Advanced antivirus software identifies and removes malware, ransomware, and other threats before they can damage your systems.

Email Vigilance

Be cautious with emails and attachments from unknown sources. They could contain malware or phishing attempts targeting your business.

Staff Training

Educate employees about cyber threats through comprehensive User Awareness Training programmes.

Regular Backups

Back up critical data regularly with our backup solutions. Ensure business continuity if systems are compromised.

Secure Connections

Use VPN connections when accessing the internet, especially on public Wi-Fi networks, to encrypt your data transmission.

Cyber Insurance

Consider cyber-security insurance to protect against financial losses from attacks. Ensure your security meets policy requirements.

Access Control

Implement strict access controls with unique credentials. Limit data access to only what employees need for their roles.

Have an Incident Response Plan

An incident response plan is a set of procedures and guidelines that a business follows when responding to a cyber-security incident. It outlines the steps to identify, contain, and remediate an incident, as well as how to communicate with relevant stakeholders.

An incident response plan ensures appropriate actions are taken quickly to minimise the impact of an incident on your business. Having predefined procedures means your team knows exactly what to do when seconds count, reducing panic and confusion during critical moments.

A well-executed incident response plan helps keep your business running smoothly, even during a cyber-security incident. It includes provisions for maintaining critical operations, activating backup systems, and ensuring minimal disruption to your customers and services.

An incident response plan helps mitigate reputation damage by demonstrating that you're taking appropriate steps to address incidents. Clear communication protocols ensure stakeholders, customers, and partners are informed appropriately, maintaining trust even during challenging situations.

Depending on your industry, you may be legally required to have an incident response plan to comply with regulations like GDPR, PCI DSS, or industry-specific standards. A documented plan demonstrates due diligence and can reduce regulatory penalties in case of a breach.
