One of the common mistakes new business owners make is overlooking the fine print when signing up for newsletters or advertising services. While these may seem harmless (and most of the time they are), unfortunately, many companies misuse this data, even selling it to third parties. This is when we start receiving fraudulent advertising , jeopardizing our financial security and online reputation. Furthermore, if we own a business, we likely have a customer database . If this information falls into the wrong hands, it can affect our customers as well and lead to serious penalties for the business.
As you've seen, taking extra precautions is always wise. Review these tips to ensure that your data and your customers' data are always protected and compliant with legal obligations regarding personal data protection.
Always read before clicking “Accept”
Do not click “Accept” without first reading the terms and conditions and privacy policy. You may have subscribed to a newsletter that sends weekly offers for products you commonly use in your business. This can be very useful, but you should check that it clearly states that the company you are providing your data to will not sell or share it with third parties without a proper legal basis.
According to the European data protection framework, every company must clearly state the purpose of the data processing , the data retention period, the legal basis used (for example, consent or legitimate interest), and the rights you can exercise as a user. If the text is confusing, overly generic, or does not specify who is responsible for the processing, it is best not to provide personal data or, at the very least, to limit the information to what is strictly necessary.
If you are the business collecting data, you must ensure that your forms include a clear notice about: who is responsible, what data you collect, what you will use it for, whether there will be international transfers , and how interested parties can exercise their rights of access, rectification, objection, erasure, restriction of processing, portability, and not to be subject to automated decisions.
Invest in security protocols and systems
Invest in security protocols and systems , especially if you accept online payments or handle sensitive information from customers, suppliers, or employees. If your server isn't secure, you could be attacked by a hacker who, with access to all your banking details and business databases, can destroy everything you've worked so hard for in a single day.
Ensure that your website and your providers' websites begin with https:// , indicating that the connection uses an SSL/TLS certificate and that information is transmitted encrypted. Additionally, it's advisable to implement technical measures such as pseudonymization and encryption of stored data , frequent backups, two-factor authentication for critical access, access logging, and robust password management policies.
Current data protection regulations also recommend that companies conduct regular risk analyses and, where processing may pose a high risk to the rights and freedoms of individuals (for example, large-scale monitoring or the use of advanced technologies), carry out data protection impact assessments . These assessments help identify vulnerabilities, define mitigation measures, and justify security decisions.
If your organization processes data on a large scale or handles special categories of data (health, ideology, biometrics, etc.), you may need to appoint a Data Protection Officer (DPO ). This professional oversees regulatory compliance, advises on privacy by design, and acts as a point of contact with supervisory authorities, significantly reducing the risk of penalties.
Properly manage sensitive data and special categories
Data revealing ethnic origin, political opinions, religious beliefs, health or sex life data , as well as biometric data intended to uniquely identify an individual, are considered special categories and require enhanced protection. Their processing is generally prohibited, unless a clear exception is provided for in the regulations and additional security safeguards are applied.
In sectors such as healthcare, law, and insurance, it is essential to use tools that allow for traceable records of consent , reliable electronic signature systems, and strict access controls so that only authorized personnel can consult the information. Any leak or loss of medical, financial, or child data can have very serious consequences for those affected and result in significant financial penalties for the responsible entity.
Furthermore, it is advisable to maintain an internal record of processing activities detailing the purposes, categories of data, affected groups, recipients, international transfers, and retention periods. This record is key evidence of proactive accountability and facilitates responding to audits or inspections by the data protection authority.
If your company uses artificial intelligence or advanced analytics systems that feed on large volumes of personal data, you should also assess the risks associated with profiling, possible automated decisions, and the need for specific impact assessments, especially in high-risk projects or those with significant effects on people.
Always use secure networks and good access practices
Always use secure networks when handling personal or financial information. Do not log into your corporate accounts, online banking, or admin panels on a public or shared network, as these may be monitored or misconfigured. Whenever possible, connect your devices through a reliable enterprise VPN and keep your operating system, antivirus software, and firewall up to date.
It's always a good idea to have a systems specialist occasionally review your company's network configuration , including Wi-Fi access points, firewall rules, and data processing equipment. Preventive maintenance helps detect exposed services, outdated devices, or weak configurations that could facilitate intrusions.
Training the team is also crucial. Many security incidents are caused by human error , such as opening phishing emails, downloading malicious files, or sharing passwords. Implementing clear device usage policies, restricting access to information based on role, and encouraging the verification of any unusual requests for personal data significantly reduces the risk.
Report any anomalies or suspicious activity you detect as soon as possible, both internally and, if appropriate, to the relevant data protection authority. Prompt detection and response to a security breach can limit the damage caused to those affected and demonstrate that your company acts with the due diligence required by law.
Adopting these technical, organizational, and legal measures not only protects your information and that of your customers, but also strengthens trust in your brand, improves relationships with suppliers and partners, and places you in a stronger competitive position in an environment where privacy and security are now decisive factors for users and buyers.
