Black Friday, Christmas and the sales season: what could a cyberattack cost your business at peak time?

Table of Contents

Peak commercial campaigns can also become moments of heightened vulnerability for businesses. A system outage, a ransomware attack, or a data breach during these periods can have far greater financial consequences than at any other time of year.

Black Friday, Christmas, and the January sales are periods of maximum activity not only for retail, but also for many industrial, logistics, and distribution companies that form part of the supply chain. A system disruption at these times can lead to financial losses, delivery delays, and contractual breaches.

What would happen if your company suffered a cyberattack precisely during one of its busiest periods? The real risk is not just the IT incident itself — it is the impact on revenue, client commitments, customer trust, the supply chain, and business continuity.

Why do cyberattack risks increase during peak commercial campaigns?

During periods of maximum activity, businesses tend to operate under greater pressure and with less room to react. Orders and transactions multiply, communications with clients and suppliers increase, and companies sometimes bring in temporary staff or expand system capacity.

This environment can favour different types of threats:

  • Ransomware. An attack can lock systems and paralyse business-critical processes at the worst possible time of year.
  • Phishing and email fraud. Cybercriminals exploit the high volume of communications to steal credentials or trigger fraudulent transfers.
  • Attacks on sales platforms and payment systems. A denial-of-service attack that brings down a sales channel during a campaign can translate directly into lost revenue.
  • Third-party technology provider compromise. Dependence on external platforms means incidents originating outside your own systems can still affect your business.

In addition, the use of artificial intelligence makes fraudulent communications increasingly convincing, which makes vigilance more important than ever.

How much can a cyberattack cost during Black Friday or Christmas?

When we think of a cyberattack, we tend to associate it with stolen information, data loss, or the cost of recovering systems. However, from the perspective of senior management or finance, there is another fundamental question: how much money would our company lose if it could not operate for a week?

The answer depends on the sector, the degree of digitalisation, and the timing of the incident.

  • For an e-commerce business, it could mean being unable to sell during the highest-revenue days of the year.
  • For a manufacturer, it could mean production lines grinding to a halt and delivery deadlines being missed.
  • For a logistics operator or distributor, it could compromise order fulfilment, goods traceability, or the ability to serve customers at all.

And in every case, reputational damage, potential claims, and extraordinary expenses needed to restore operations can be added on top of direct recovery costs. That is why cyber risk must be analysed as a business risk, not solely as an IT department matter.

Cybersecurity and cyber insurance: two complementary tools

The first line of defence is a sound cybersecurity strategy. The most important measures include multi-factor authentication, endpoint protection, network firewalls, using software that is actively supported and regularly updated, protected and encrypted offline backups, employee training, and segmentation between IT and OT networks.

But even companies that invest adequately in prevention can still suffer an attack. This is where cyber insurance for businesses comes in. A well-designed cyber risk insurance policy can help manage both the immediate response to an incident and certain subsequent financial consequences.

Coverage What it includes
Incident response Digital forensics, technical containment, legal advice, crisis communications, and monitoring of compromised data.
Loss of profits Business interruption caused by an incident affecting your own systems or a technology provider.
Data recovery Restoration of systems and data affected by the attack.
Cyber extortion Coverage of ransom payments and negotiation management in ransomware attacks.
Civil liability and penalties Third-party claims and administrative sanctions arising from a data breach.
Technology fraud Fraudulent transfers, identity theft, invoice manipulation, and unauthorised use of computing resources.

Not all cyber insurance policies offer the same coverage or respond in the same way to a business interruption. That is why it is not enough to check whether your company has a cyber risk policy in place — you need to assess whether the insurance programme actually responds to your real exposure.

Is your company prepared for a cyberattack at its worst commercial moment?

Before a high-activity campaign, it is worth asking a few key questions:

1. Do we know which processes are critical?

Identify the systems whose failure would compromise production, sales, distribution, or customer service.

2. Have we quantified the financial impact of a disruption?

Losing a day of operations during a normal period is very different from losing it during the highest-revenue week of the year.

3. Do we have a tested response plan?

Having clear procedures, defined roles, and specialist support providers can make a significant difference to recovery time.

4. Do we know the limitations of our insurance policy?

It is important to review deductibles and waiting periods, sub-limits, exclusions, and the conditions that activate business interruption coverage.

5. Are we accounting for third-party dependencies?

Operations can be affected by an incident at a supplier — whether technology-related or not — even if your own systems have not been directly attacked.

Frequently asked questions about cyber insurance and cyberattacks during commercial campaigns

1. What is cyber insurance for businesses?

Cyber insurance is a policy that covers the financial consequences of a cyberattack: from incident response costs to loss of profits due to business interruption, civil liability to third parties, and administrative penalties.

2. Why are cyberattacks more frequent during Black Friday and Christmas?

Because businesses are handling higher transaction volumes, more communications, and in some cases temporary staff who are less well trained. Cybercriminals exploit that pressure and reduced reaction time to launch ransomware, phishing, or denial-of-service attacks.

3. What does cyber insurance cover in a ransomware attack?

Depending on the policy, it can cover the extortion payment (ransom), data recovery, business interruption while systems are down, and the costs of the technical and legal response teams.

4. Does cyber insurance cover attacks through suppliers?

Some policies include business interruption coverage for incidents affecting technology providers (cloud, SaaS, payment platforms). This is one of the most important points to review before taking out or renewing a policy.

5. What is the difference between cybersecurity and cyber insurance?

Cybersecurity refers to the technical and organisational measures taken to prevent or detect an attack. Cyber insurance is the financial tool that covers the economic consequences when an attack succeeds despite those measures. They are complementary, not mutually exclusive.
