Cyber Attack

Cyber Attack Really Cost

The True Cost of Complacency: How Much Will a Cyber Attack Really Cost Your Business?

Most UK businesses think a cyber attack will “never happen to them.” Then it does.

And when it does, the cost isn’t just a fine or a ransom payment—it’s your business, your reputation, your future.

60% of UK businesses shut down within six months of a breach.

The average cost of a UK data breach? £8,460. But for many, it’s far worse.

Ransomware payments are skyrocketing. The average UK ransom demand? £200,000+.

And those are just the visible costs. The real cost of a cyber attack goes much deeper.

The Hidden Costs of a Cyber Attack

???? Operational Collapse – Your emails, files, customer records, and banking access locked down. No transactions. No orders. No customer service. Every second of downtime bleeds money.

???? Reputation Damage – Customers don’t forgive data leaks, downtime, or financial fraud. One breach, and they lose trust forever.

???? Legal Trouble & Fines – The UK GDPR & Data Protection Act hold businesses responsible for failing to prevent breaches. Fines can hit £17.5M or 4% of turnover.

???? Supply Chain Fallout – If your business is breached, your partners & clients are at risk too. Many companies drop vendors that fail security checks.

???? Cyber Insurance Won’t Save You – Many policies won’t pay out if your security was weak, you didn’t follow compliance rules, or if the breach was due to negligence.

???? Hackers Might Come Back – If you pay a ransom, criminals see you as an easy payday. Many businesses are hit again within months.

Real UK Businesses That Didn’t Survive the True Cost of a Cyber Attack

The Small Manufacturer That Lost £500,000 in Fake Payments – A finance team unknowingly processed multiple fraudulent invoices after a hacker took over their email. The result? Half a million pounds gone, with no way to recover it.

The Accountancy Firm That Never Recovered – A phishing email tricked an employee into entering login details for their client database. Every client’s sensitive financial information was stolen. Customers left. Trust was destroyed. The firm shut down.

The Retailer That Lost a Year of Data – A ransomware attack encrypted all stock records, orders, and financials. Their backups weren’t up to date. They refused to pay the ransom and lost a year’s worth of critical business data.

The Law Firm That Got Publicly Shamed – A cybercriminal group stole and leaked high-profile client cases. The press found out. Customers panicked. The firm’s reputation was permanently damaged.

How to Stop a Cyber Attack from Killing Your Business

???? 1. Treat Cybersecurity as a Business Investment, Not an IT Expense – The cost of prevention is always lower than the cost of disaster.

???? 2. Use Multi-Factor Authentication (MFA) on Every Account – If your passwords get stolen, MFA stops hackers from using them.

???? 3. Back Up Everything, Every Day – Not just on your office server—offsite, encrypted, and tested.

???? 4. Train Your Employees to Recognise Scams – 91% of cyberattacks start with a phishing email. Your staff needs real-world, hands-on training.

???? 5. Have a Cyber Incident Plan – Before You Need It – If you’re hacked tomorrow, who does what? If you don’t have a step-by-step response plan, you’re gambling with your business.

???? 6. Get Professional Security Support – Hackers attack 24/7. Your cybersecurity needs to be proactive, not reactive. A Managed Security Provider (MSSP) can monitor threats and stop attacks before they hit.
