How much does a ransomware attack cost?

Calculating Costs

Ransomware attacks cost organisations far more than just the ransom payment. In 2024, the average total cost of a ransomware incident reached £3.80 million, a sharp increase from previous years.

If you are reading this because you have experienced a ransomware incident and are unsure how to deal with it, contact Zensec immediately.

This total includes not only ransom payments but also system recovery, business downtime, legal expenses, lost revenue, reputational damage, and ongoing security enhancements. In most cases, the ransom demand is only a small fraction of the overall impact – with recovery, incident response, and regulatory fines often driving the majority of costs.

It’s clear why every business must take proactive steps to reduce the risks associated with ransomware attacks.

In this post, we’ll explore how much ransomware attacks can cost, and how you can prepare for them. 

What makes up ransomware attack costs?

Ransomware incidents will often impact multiple departments and areas of your organisation, with each individual cost adding to the overall financial impact. Unfortunately, the expenses can extend far beyond the initial attack. 

Ransom payments 

Ransom payments are the direct money paid to attackers. In 2024, the average ransom payment was approximately £1.48 million, though demands vary widely based on the target organisation’s size and perceived ability to pay. 

Some attacks demand hundreds of thousands of dollars, while others reach tens of millions for large enterprises.

Incident response and recovery costs

You’ll also need to factor in expenses for digital forensic experts, including cyber security consultants, digital forensics experts, overtime for IT staff and system rebuilding. 

The average company might spend between £1.11 million and £2.22 million on professional services to investigate the breach, remove malware, restore systems, and implement security improvements.

Business downtime losses

As you can probably guess, business downtime losses usually represent the highest costs. When ransomware encrypts critical systems, operations halt completely. 

Manufacturing companies lose production revenue, retail businesses can’t process sales, and service providers cannot serve customers.

Large enterprises can lose millions of dollars per day during extended outages.

Legal and regulatory expenses

The GDPR is in place to protect consumers’ personal information, and any breaches can result in significant fines. If your organisation suffers an attack, you have a duty to notify affected customers. 

It’s also vital to provide credit monitoring services, pay regulatory fines, and handle potential lawsuits. 

You may also have to pay additional fines depending on your industry. For example, healthcare businesses might face HIPAA violations. 

Reputational damage costs

Reputational damage is a long-term expense that includes customer churn, lost sales opportunities, and decreased market value for publicly traded companies. 

These impacts often persist for months or years after the initial attack, making them difficult to quantify but potentially substantial.

Average ransomware costs by organisation size

Ransomware costs vary significantly based on organisation size, industry, and attack complexity. Smaller businesses face lower absolute costs but often struggle more with the financial impact relative to their resources: 

Small businesses

Ransomware costs for small businesses range between £88,000 and £924,000. While these amounts seem smaller than enterprise costs, they can represent a devastating percentage of annual revenue for small organisations. 

Many small businesses lack comprehensive cyber insurance or extensive IT resources, making recovery more challenging and expensive.

Medium-sized organisations

The average costs can range from  £740,000 to £3.70 million per incident. 

These companies often have more complex IT environments than small businesses but lack the extensive security resources of large enterprises, creating a challenging middle ground for prevention and recovery.

Large enterprises

Large enterprises experience the highest absolute costs, often exceeding £7.40 million for severe incidents. However, these organisations typically have dedicated cyber security teams, comprehensive insurance coverage, and established incident response procedures that can help minimise some cost categories.

Several factors influence where an organisation falls within these ranges:

  • Industry type: Healthcare, finance, and critical infrastructure face higher costs due to regulatory requirements and operational criticality

  • Attack sophistication: Advanced persistent threat groups typically cause more damage than opportunistic attackers

  • Backup quality: Organisations with well-maintained, regularly tested backups recover more quickly and at a lower cost.

  • Response speed: Faster containment and response reduce overall costs significantly

Global ransomware attack statistics

Ransomware is a global threat costing organisations billions of pounds each year. By understanding global statistics, you can assess how at risk your organisation is: 

  • Global Impact: The global economic impact from ransomware reached approximately £33.29 billion when combining all victim costs worldwide. This figure includes ransom payments, recovery expenses, lost productivity, and economic ripple effects across supply chains and partner networks.

  • Attack frequency: Attack rates continue to increase, with companies experiencing them every 11 seconds globally (Cybercrime Magazine). Not all attempts succeed, but the volume demonstrates the persistent nature of the threat and the likelihood that most companies will face an attack eventually.

  • Payment Statistics: Around 32% of ransomware victims pay the demanded ransom, though payment doesn’t guarantee full data recovery. Organisations that pay ransoms recover an average of 69% of their encrypted data, meaning significant data loss often occurs regardless of payment decisions.

  • Recovery Timeframes: The average business takes 22 days to fully restore its operations after a ransomware attack. During this period, businesses operate with reduced capacity or complete shutdowns, directly impacting revenue and customer relationships.

  • Repeat Attacks: 80% of organisations that pay ransoms will face repeated attacks. This drastically increases ransomware’s long-term cost for organisations that pay initial demands.

How professional response reduces costs

Expert incident response teams can help your organisation reduce the costs of ransomware attacks. 

With better negotiation outcomes, faster containment times, and effective recovery, specialist teams can access advanced tools and extensive internal experience that the average organisation won’t have. 

  • Rapid Containment: The most important thing is to prevent ransomware from infiltrating additional systems. Professionals will isolate affected systems in hours, avoiding the attack from escalating into a company-wide disaster.  
  • Data Recovery Expertise: Data recovery experts can often restore operations without the organisation paying ransoms. Professional teams maintain relationships with security researchers who develop decryption tools and leverage advanced techniques for recovering data from damaged systems.
  • Negotiation Experience: If a payment is necessary, negotiators can reduce the amount your company has to pay. They have advanced knowledge of market dynamics and attacker psychology, often resulting in a lower ransom. 
  • Evidence Preservation: You’ll also need proper documentation for law enforcement, insurance claims, and regulatory reporting. Professional teams maintain a chain of custody for digital evidence while conducting recovery operations, supporting potential criminal prosecutions and insurance payouts.

Organisations that engage professional incident response teams within the first 24 hours of an attack typically experience 30-50% lower total costs than those attempting internal responses. The combination of faster recovery, better outcomes, and proper documentation justifies most companies’ expense of professional services.
