LGPD in practice for SMEs

Compliance with the General Data Protection Law , known by the acronym LGPD , is often treated by small and medium-sized enterprises as a concern exclusive to large corporations . This perception ignores an important point: the voice and messaging channels used in daily customer service are also subject to specific legal requirements, often neglected precisely by smaller companies.

Why corporate communication is a high-risk area

Phone calls and conversations via messaging apps involve a large scale of personal data. After all , a customer's voice and the content of a WhatsApp conversation are data protected by law. Therefore , they require clear principles of purpose, necessity, and transparency.

Some failures frequently occur in this type of operation:

Absence of any formal data retention policy.
The consent of the contacts was not documented in any way.
Use of personal channels without any centralized corporate management.

This set of failures exposes the company to administrative sanctions and significant legal liabilities.

The recording warning that few companies do correctly.

The recording of telephone calls is supported by legitimate legal bases , such as compliance with regulatory obligations or contract execution. Even so, the law requires prior transparency , informing the customer that the call is being recorded and the purpose of that recording.

In practice, many companies skip this step, starting the recording without any warning at the beginning of the call. Setting up a simple message informing about the recording and directing to the privacy policy solves this problem with relatively low technical effort.

Storage, lifecycle, and deadlines that nobody respects.

In addition to the warning, the way audio files are stored also often violates basic principles of the LGPD (Brazilian General Data Protection Law). Some essential precautions include:

Proper cryptography of audio files, avoiding unprotected local folders or sending them via insecure email.
Profile-based access controlensuring that only authorized individuals have access to the recordings.
Defining a maximum retention periodsince indefinite storage violates the principle of necessity.
Automated exclusion of the files at the end of the deadline, without depending on manual action.

Industry best practices recommend a retention period of up to six months for recordings intended for internal monitoring , except in situations that require a longer period, such as ongoing legal disputes.

WhatsApp for Business and the problem of consent.

Using WhatsApp for corporate customer service presents additional challenges. When customer service is conducted via employees' personal cell phones , without centralized management, the company loses the ability to audit these conversations and ensure legal compliance.

Some measures help to consistently reduce this risk:

Restrict corporate support to devices and platforms formally managed by the company.
Clearly record each contact's consent before sending proactive messages.
Offer a simple option to unsubscribe from all communications sent.

How Next_security helps close these gaps.

Many of the shortcomings listed above are a result of a lack of structure: retention policies that exist only on paper, consents that have never been documented, recordings stored without adequate encryption. It is this type of gap that a well-implemented security layer solves , transforming legal requirements into automated processes, instead of relying on the memory or goodwill of each employee.

Next_security works in this scenario with risk analysis and management , identifying vulnerabilities in the company's voice and messaging channels, and 24/7 monitoring with alerts. The solution also includes training and awareness for teams , since a large part of compliance failures come from informal processes, as well as support for compliance with the LGPD (Brazilian General Data Protection Law) and a specialized incident response team.

For an SME without an internal structure dedicated to compliance, this combination reduces the risk of sanctions without requiring the creation of a legal or technical department from scratch.

Compliance as a competitive advantage

Treating the LGPD (Brazilian General Data Protection Law) solely as a bureaucratic obligation is a common strategic mistake among small and medium-sized enterprises. Companies that demonstrate maturity in data protection build a higher level of trust with customers, suppliers, and partners.

From a strategic point of view, compliance is no longer just a matter of avoiding fines. It has become a differentiating factor observed in more rigorous commercial evaluation processes , and companies that organize their data governance now reap, in the medium term, an advantage that goes beyond legal compliance.
