Data theft prevention tips for business and best practices for employees

Data protection has become a priority for companies and individuals in the digital age. The increasing digitalisation of our lives and the rise of cyber threats make it more important than ever to take measures to ensure the security of our information.

Recent data shows that the leading causes of data breaches are sophisticated cyberattacks, human error, and vulnerabilities in third-party systems. In 2024, the average global cost of a breach rose to $4.88 million. As threats increasingly target cloud environments and supply chains, it is more important than ever for companies to strengthen their cybersecurity strategies—focusing on employee training, close oversight of vendors, and adopting a zero-trust model—while staying compliant with regulations like the GDPR. Our offices and companies are also at risk from the various dangers that our data faces. A mistake in managing passwords, clicking on a suspicious link, or incorrect settings on devices can lead to serious problems for our privacy and the security of our organisation.

If you are still unclear about the legal and operational foundations of data protection, we recommend reviewing some key data protection for your business.

How to prevent data interception and theft in your company?

Here are 10 tips to prevent data theft risks for your company that your employees should apply:

Keep any sensitive data away from your desk

To protect information in your physical workspace:

• Keep your workspace clean and tidy.
• Do not leave documents containing personal or confidential information in plain sight.
• Avoid using sticky notes, reminders, or memos with passwords or other identifying details.

You never know who might see them!

Create and protect strong, personal passwords

Passwords are personal and non-transferable. Do not share your passwords or usernames with others, even colleagues.  Make sure that you create secure passwords by using a mix of letters, numbers, and special characters—symbols like “@,” “#,” or “!” can help make them more secure.

Use corporate email only for professional purposes

Be cautious when using the company email. Use it only exclusively for work purposes. Avoid subscribing to websites or platforms or downloading applications that could compromise the company’s data security.

Detects potential fraud with suspicious links

Be careful with the links you click on! Be wary of suspicious links, particularly in emails or on unreliable websites. If you suspect that your data has been compromised, inform your supervisor immediately.

Share sensitive files with secure methods

Share information securely:

• Use sites like WeTransfer to share important documents.
• Apply two-factor authentication whenever you log into sensitive and critical services.
• Encrypt sensitive documents before storing them in the cloud or sharing them via email.
• When sending files with personal data or confidential information, use secure and reliable methods.

Protect and update your technological equipment

Keep your equipment updated. Ensure your computer is regularly updated to function properly and remain secure. Run any pending updates and make sure your antivirus and firewall are up to date.

Work from home securely from reliable networks and devices

Work from home or any other working spot safely:

• Use updated and secure devices with updated antivirus and firewalls.
• Avoid connecting to the company portal from public locations.
• Make sure to use secure Wi-Fi networks and avoid open public networks, which are often a risk.

Be cautious when using artificial intelligence with sensitive data

Be careful when using artificial intelligence tools. Be cautious when entering information into these apps or websites. Do not share personal or confidential data without taking the necessary precautions.

Act quickly if you detect a possible information leak

If you suspect that someone has accessed your personal data or confidential information, report it straight away. Quick reporting can prevent serious consequences from a data breach.

Protect documents and devices outside the office

Take care when transporting work materials. Equipment, files, notes, and reports may contain confidential or personal information. Handle them responsibly and ensure they are taken to safe locations.
