Yes, collecting customer requests via messaging is safe as long as you use apps with end-to-end encryption (WhatsApp, Signal), comply with GDPR (consent, legal notice) and do not share sensitive data over unencrypted channels.

What Security Risks Exist When Collecting Leads via Messaging?

Main Threats and How to Avoid Them

Collecting customer requests via messaging brings risks: phishing (identity theft), data interception on unsecured networks, unauthorized access to business accounts and GDPR non-compliance if consent is handled badly. According to a 2025 Gartner report, 40% of data breaches in SMEs came out of uncontrolled messaging channels. To reduce them, use apps with end-to-end encryption, turn on two-factor authentication, train the team in cybersecurity and work with lead management platforms that comply with European regulations.

Legal Obligations for Companies in Spain

The General Data Protection Regulation (GDPR) requires that any collection of personal data, messaging included, follows the principles of informed consent, data minimization, transparency and the right to erasure. In Spain, the Spanish Data Protection Agency (AEPD) has published specific guidelines on the use of WhatsApp in companies. You have to tell the customer what data is collected and for what purpose, and obtain their explicit consent (a checkbox or a confirmation message). You must also record processing activities and let the user exercise their ARCO rights (access, rectification, cancellation and opposition).

What Tools Do Experts Recommend for Secure Lead Capture?

Platforms with Regulatory Compliance and Encryption

Digital marketing and cybersecurity experts recommend platforms with encryption, consent management and GDPR compliance. According to a 2025 Think with Google study, 72% of users trust companies that use official, secure channels more. ManyChat, HubSpot and WATI bring consent templates, conversation logging and encryption. They also integrate chatbots that collect data automatically and transparently. For SMEs in Spain, the combination of WhatsApp Business API with a CRM like HubSpot is the most balanced option between security and usability.
