Quick answer
Yes, it is safe to collect customer requests via messaging as long as you use apps with end-to-end encryption (WhatsApp, Signal), comply with GDPR (consent, legal notice) and avoid sharing sensitive data over unencrypted channels. In 2026, 65% of Spanish SMEs already use secure chatbots to capture leads (Source: Statista).
In this article we address the security of capturing leads through messaging apps such as WhatsApp, Telegram and Messenger. We explain the risks (phishing, data leakage, non-compliance) and measures to mitigate them: encryption, privacy policies, lead management tools with GDPR compliance. We also include updated 2026 data on business adoption and practical recommendations to implement a secure system in your business, with real examples and concrete steps.
Collecting customer requests via messaging carries risks such as phishing (identity theft), data interception on unsecured networks, unauthorized access to business accounts and GDPR non-compliance if consent is not properly managed. According to a 2025 Gartner report, 40% of data breaches in SMEs originated from uncontrolled messaging channels. To minimize them, it is essential to use apps with end-to-end encryption, implement two-factor authentication on accounts, train the team in cybersecurity and use lead management platforms that comply with European regulations.

The General Data Protection Regulation (GDPR) requires that any collection of personal data, including via messaging, complies with principles such as informed consent, data minimization, transparency and the right to erasure. In Spain, the Spanish Data Protection Agency (AEPD) has issued specific guidelines for the use of WhatsApp in companies. It is mandatory to inform the customer what data is collected, for what purpose, and obtain their explicit consent (e.g., via a checkbox or confirmation message). Additionally, you must record processing activities and allow the user to exercise their ARCO rights (access, rectification, cancellation and opposition).
| Platform | E2E Encryption | Integrated Consent | Activity Logging |
|---|---|---|---|
| WhatsApp Business | Yes | Not native (requires chatbot) | Yes (with external tool) |
| Telegram | Only secret chats | No | No |
| Signal | Yes | Not native | Yes (with API) |
Digital marketing and cybersecurity experts recommend platforms that integrate encryption, consent management and GDPR compliance. According to a 2025 Think with Google study, 72% of users trust companies that use official and secure channels more. Tools like ManyChat, HubSpot and WATI offer consent templates, conversation logging and encryption. Additionally, they integrate chatbots that automate data collection with full transparency. For SMEs in Spain, the combination of WhatsApp Business API with a CRM like HubSpot is the most balanced option between security and usability.
