The National Cyber Security Centre (NCSC) is the UK’s lead authority on cybersecurity, part of GCHQ. It provides expert guidance, threat alerts, and practical tools to help businesses of all sizes, including small and micro enterprises, protect themselves from digital threats. For small businesses with limited in-house IT expertise, the NCSC offers accessible, jargon-free resources tailored to real-world concerns—like phishing, ransomware, and data loss. Their “Small Business Guide” and accompanying actions checklist help SMEs quickly understand and implement basic protections. They also provide free services like the Early Warning tool, Cyber Action Plan generator, and guidance on supply chain security. NCSC actively collaborates with law enforcement, industry, and government to ensure small businesses are kept informed of the latest threats and security trends. With cybercrime evolving rapidly, NCSC acts as a trusted resource to help small firms improve resilience and build customer confidence.
The Information Commissioner’s Office (ICO) is the UK’s independent regulator for data protection and privacy rights. It enforces the UK GDPR and Data Protection Act, and provides guidance on how businesses should collect, store, and use personal data lawfully and responsibly. For small businesses, the ICO is an essential resource, offering practical toolkits, templates, and self-assessment checklists to help ensure compliance. SMEs can also access advice via their helpline or use the ICO’s data protection fee checker to determine their legal obligations. The ICO recognises that small businesses may not have dedicated compliance officers, so it has designed its resources to be understandable and actionable. This support helps small firms avoid fines, protect customer trust, and ensure transparency. Whether handling customer emails, managing employee records, or using CCTV, small businesses can look to the ICO for clear, consistent guidance.
Action Fraud is the UK’s national reporting centre for fraud and cybercrime. Operated by the City of London Police, it serves as the central point for reporting scams, financial fraud, business impersonation, and cyber-attacks. Small businesses face increasing risks from invoice fraud, ransomware, and business email compromise, and Action Fraud provides both a reporting mechanism and educational tools to counter these threats. Their Business Fraud Centre offers fraud prevention tips tailored to SMEs, helping owners recognise common scams and respond effectively. Businesses that fall victim to fraud can submit a report online or via phone, and their case is passed to the National Fraud Intelligence Bureau for assessment. The site also provides fraud alerts, sector-specific guidance, and cybercrime updates. By encouraging businesses to report incidents, Action Fraud helps build intelligence to identify criminal networks and patterns—protecting the wider SME community.
Cyber Aware is a UK government-backed campaign designed to raise public and business awareness of cybersecurity best practices. Aimed especially at individuals and small organisations, it focuses on six key actions businesses can take to protect themselves, such as using strong passwords, enabling 2-step verification, and keeping software updated. Cyber Aware provides simple, impactful advice to improve digital hygiene, with a focus on things that small business owners can implement without technical support. Their website includes checklists, videos, and a “Cyber Action Plan” tool that generates a personalised set of recommendations.

For small businesses short on time and IT budget, Cyber Aware is a quick, accessible way to raise baseline cyber resilience.
Companies House is the UK’s official registrar of companies, responsible for incorporating and dissolving limited companies, maintaining public records, and ensuring corporate transparency. While primarily known for business registration, Companies House plays a growing role in fraud prevention and data accuracy—issues critical to small business trust and reputation. Small firms can use Companies House to verify other businesses, detect suspicious changes to their own company records, and protect their identity through services like the PROOF scheme (to prevent unauthorised filings). In recent years, Companies House has enhanced its digital services to support easier compliance, including tools to update details, file accounts, and monitor directorships. They are also involved in ongoing reforms to strengthen identity verification and reduce the abuse of company registrations—efforts that directly protect small businesses from being impersonated or misused.
The Financial Conduct Authority (FCA) is the UK’s independent regulator for financial services firms and markets. While traditionally focused on banks, insurers, and large institutions, the FCA plays a crucial role in ensuring that small businesses—particularly those offering financial products or using third-party financial platforms—operate in a secure and fair environment. For SMEs in sectors like fintech, lending, accountancy, or investment, FCA guidance is essential for compliance and risk mitigation. The FCA also protects small business customers by enforcing rules around fair treatment, transparency, and protection from financial misconduct. Increasingly, the FCA focuses on cyber resilience, requiring regulated firms (including small ones) to ensure adequate protection of client data and digital systems. Small businesses can access publications, alerts, and regulatory updates directly from the FCA, as well as make complaints or report fraudulent financial activity. Through its innovation hub and regulatory sandbox, the FCA also supports small, innovative firms in testing new services safely.
HMRC is the UK’s tax authority and a critical interface for all small businesses handling payroll, VAT, self-assessment, or corporation tax. Beyond its core fiscal responsibilities, HMRC plays a frontline role in fraud prevention, cybercrime response, and digital security education. Many small businesses are targeted by scams impersonating HMRC—via email, text, and phone—which makes HMRC’s real-time scam alerts and reporting tools especially valuable. The department publishes regular updates to help SMEs recognise fraudulent communications and avoid falling victim to phishing attacks. HMRC also provides secure digital services for tax filing and account management, including two-factor authentication and data security features. For small businesses needing support, HMRC’s Business Tax Account, webinars, and compliance resources help ensure accurate filing and protection against common risks. Their commitment to secure digital operations ensures that even the smallest firms can manage their taxes safely and with confidence.

SMEs are often the targets of rogue traders and scam suppliers, and Trading Standards helps protect them by investigating complaints and providing prevention advice. Many local Trading Standards teams also offer primary authority partnerships—giving small firms direct access to tailored regulatory advice. Resources like “Business Companion,” a government-backed portal, provide comprehensive legal guidance free of charge. Small businesses can also access enforcement updates, scam alerts, and product recalls. In a world of complex regulations and fast-moving threats, Trading Standards helps small firms stay compliant, competitive, and trusted by their customers.
The National Crime Agency (NCA) is the UK’s top-level law enforcement agency tackling serious and organised crime, including cybercrime, fraud, and economic crime. Of particular interest to small businesses is the work of the NCA’s National Cyber Crime Unit (NCCU), which coordinates national and international responses to cyber threats. The NCA partners with regional police cyber units to help protect UK businesses from ransomware, online extortion, and data theft. Small firms can benefit from NCA resources such as threat briefings, security alerts, and case studies detailing real-world cyber-attacks. The NCA also supports law enforcement efforts to disrupt criminal marketplaces and shut down fraud operations that target SMEs. By acting as both an enforcement body and a strategic threat assessor, the NCA helps create a safer environment for small businesses to operate online. Although not a direct service provider to SMEs, its impact is felt in the disruption of cybercrime networks and the intelligence shared with local police and agencies like the NCSC.

Police CyberAlarm is a free cybersecurity monitoring tool developed by UK policing to help small and medium-sized organisations understand and improve their cyber resilience. Once installed, it acts like a “CCTV camera” for digital traffic—monitoring and reporting suspicious activity to help identify threats before they become breaches.

For small businesses with limited IT security teams, Police CyberAlarm provides real-time alerts, regular threat reports, and actionable insights that can support incident prevention and response. It’s especially useful for identifying scanning attempts, malicious connections, and known threat actor behaviours.
