Cyber security guidance for organisations
When something unexpected happens, such as a cyber incident, it can be difficult to know how to react. Naturally, you will want to resolve the problem as quickly as possible so you can resume business as normal.

Small businesses are often at risk from cyber threats, but many don’t have the time, resource, or specialist knowledge to deal with them. The Cyber Action Toolkit provides small businesses with clear, bite-sized actions to work through at their own pace, helping protect their business’s money and reputation from cyber criminals free of charge.
There are a number of free services and cyber security tools to help you protect your business. For more information and advice, view our comprehensive list of cyber security services.
What makes the Cyber Action Toolkit different?
Actionable guidance
Information is broken down into manageable, step-by-step sections.
Progress tracking
Businesses can track their progress and complete the toolkit in their own time.
Tailored design
The toolkit has been designed with small businesses, for small businesses.
Starting point for cyber security
Ideal for those who are unsure where to start, designed to build confidence and help progress to Cyber Essentials certification - the government-backed minimum standard.
The Cyber Action Toolkit creates a natural pathway towards Cyber Essentials certification - the government-backed - scheme that protects businesses against common online threats. As users progress through the toolkit's layers and gain confidence, they're building the foundations needed for Cyber Essentials, breaking down what might seem like a complex process into manageable steps that grow with their business.
