How Can You Protect Yourself From A Third Party's Poor Security Practices

We used to say there were two certainties in life: death and taxes. Now there is a third: at some point, often through no fault of your own, your personal data may be leaked, sold, or exposed online.

The good news is that while you cannot remove the risk entirely, you can reduce your exposure and take action if an organisation fails to protect your information.

Why data exposure has become the new normal

Every order, signup, app, and account adds to your digital footprint. Businesses collect data, brokers trade it, and criminals target it. Even careful people can be caught in a breach. In the UK, organisations must report certain breaches to the Information Commissioner’s Office (ICO) within 72 hours and tell affected individuals quickly if the risk is high.

How to tighten your personal data controls

Protecting your data is about reducing exposure, making stolen information less useful, and spotting problems early.

• Use a password manager and strong, unique passwords.
• Turn on multi-factor authentication for email, banking, and social accounts.
• Review privacy settings and remove permissions you do not need.
• Share less personal information unless it is truly necessary.
• Keep devices, browsers, and apps updated.

Use secure products that help you spot trouble early

Good habits matter, but the right tools help too. Reputable antivirus and endpoint security can block malware and unsafe websites, while monitoring tools can flag unusual logins, suspicious behaviour, or exposed credentials before a small issue becomes a major one.

• Choose trusted security software with automatic updates and real-time protection.
• Use device encryption and screen locks on laptops and phones.
• Back up important files regularly.
• Monitor bank accounts and key online services for unusual activity.

What to do if a business leaks your data through poor security

If a business exposes your data, act quickly. Contact the organisation through its official channels, ask what happened and what data was involved, and change affected passwords immediately. If financial details or identity documents may be at risk, contact your bank or provider and monitor accounts closely.

• Keep records of messages, calls, and screenshots related to the breach.
• Watch for phishing, scam texts, and fake compensation offers.
• Check for unauthorised activity and change security questions if needed.
• Complain to the ICO if you believe the organisation mishandled your data.
• In the UK, you may be able to seek compensation if the breach caused loss or distress.

Keep evidence of the breach and its impact. If the consequences are serious, consider speaking to a qualified solicitor or specialist adviser. You do not have to accept the fallout quietly if a business failed to protect your information.

How does this affect you or your business?

Data leaks are now a routine risk of modern life. But you are not powerless. Share less, secure more, use trusted tools, and know your rights when organisations get it wrong.
