Data protection

1. Local data protection laws and scope

The main data protection legislation is the Federal Law on the Protection of Personal Data held by Private Parties (the “Data Protection Law”) and its supplementary regulation (the “Data Protection Regulations”), together the “Data Protection Legislation”. The Data Protection Law came into force in July 2010 and the Data Protection Regulation came into force in December 2011. Other relevant legislation containing data protection provisions includes:

  • Articles 6 to 16 of the Mexican Constitution;
  • The Privacy Notice Guidelines, which govern the content of data privacy notices and obtaining consent for processing personal data;
  • The General Law for the Protection of Personal Data in Possession of Obligated Subjects governs personal data held by public bodies; and
  • The Federal Consumer Protection Law governs certain aspects concerning marketing activities.    

Additionally, Mexico is a signatory of international agreements on Data Protection, like the Convention for the Protection of the People Regarding the Automated Treatment of Personal Information. Mexico is also a member or the Inter American Network of Data Protection.

  • The Personal Data Protection Act (“ZVOP-1”) is an act that became applicable prior to the EU General Data Protection Regulation (“EU GDPR”) and considering Slovenia has not yet adopted a new act which would supplement the EU GDPR, provisions which are not regulated by the EU GDPR and which do not conflict with it still apply.
  • The Information Commissioner Act (“ZInfP”) sets the competences and powers of the Information Commissioner.
  • The Electronic Communications Act (“ZEKom-1”) sets the requirements for electronic communications networks and services, including cookies and direct marketing by electronic means. ZEKom-1 implemented the EU Privacy and Electronic Communications Directive (e-Privacy Directive) in Slovenia. 

2. Data protection authority

The Federal Institute for Access to Information and Data Protection (Instituto Nacional de Acceso a la Información y Protección de Datos Personales or "INAI"), is responsible for overseeing the Data Protection Legislation. Its aim is to encourage access to all public information about governmental activities, and budgets, as well as seeking the protection of personal data and the right to privacy.
The INAI, if requested by a data subject, may carry out an investigation to ensure compliance with the Data Protection Legislation of a specific undertaking and sanction those found to be in breach the Data Protection Legislation.

Information Commissioner of the Republic of Slovenia:

3. Anticipated changes to local laws

There are no anticipated changes. Notwithstanding, the President of Mexico suggested in January that the INAI would be replaced by a State-controlled body. No additional details or timelines have been provided.

Supplementing the EU GDPR

Expected adoption of the new Personal Data Protection Act (“ZVOP-2”), which would ensure the implementation of the EU GDPR.


The new EU ePrivacy Regulation is set to replace the ePrivacy Directive in relation to the privacy of electronic communications. In effect, this will replace local EU Member State ePrivacy laws.

4. Sanctions & non-compliance

The INAI has the has the authority to impose the following administrative fines:

  • 100 to 160,000 units of measure 1 1 unit of measure = MXN 86.88 (Mexican Pesos)  for:
    • Acting negligently or fraudulently in processing and responding to requests for personal data access, rectification, cancellation or objection;
    • Fraudulently declaring the inexistence of personal data where such exists in whole or in part in the databases of the Data Controller;
    • Processing personal data in violation of the principles established in the Data Protection Law;
    • Omitting from the Privacy Notice any or all of the information it requires;
    • Maintaining inaccurate personal data when such action is attributable to the Data Controller, or failing to perform legally due rectifications or cancellations where the data subject’s rights are affected; and
    • Failure to comply with the notice warnings issued by the INAI.
  • 200 to 320,000 units of measure 2 1 unit of measure = MXN 86.88 (Mexican Pesos) for:
    • Breaching the duty of confidentiality set out in the Data Protection Law;
    • Materially changing the original data processing purpose in contravention of the Data Protection Law;
    • Transferring data to third parties without providing them with the Privacy Notice containing the limitations to which the data subject has conditioned data disclosure;
    • Compromising the security of databases, sites, programmes or equipment;
    • Carrying out the transfer or assignment of personal data outside of the cases where it is permitted under the Data Protection Law;
    • Collecting or transferring personal data without the express consent of the data subject where required;
    • Obstructing verification actions of the INAI;
    • Collecting data in a deceptive and fraudulent manner;
    • Continuing with the illegitimate use of personal data when the INAI or the data subjects have requested such use be ended;
    • Processing personal data in a way that affects or impedes the exercise of the rights of access, rectification, cancellation and objection set;
    • Creating special data databases in violation of the Data Protection Law.   

In the event that the infractions mentioned in the preceding paragraphs persist, an additional fine of 100 to 320,000 units of measure 3 1 unit of measure = MXN 86.88 (Mexican Pesos)  can be imposed.

Sanctions may be doubled for any of the above infractions committed in the treatment of sensitive data.

Administrative sanctions:

Until ZVOP-2, which would ensure the implementation of the EU GDPR, is adopted, the Information Commissioner does not have legal ground for imposing administrative fines under the EU GDPR, but only fines under the ZVOP-1, which are not contrary to the EU GDPR.  

Fines under ZVOP-1 amount up to EUR 12,500.

Criminal sanctions:

In the event of a criminal offence of misuse of personal data, a fine or imprisonment from one to five years may be imposed.


The Information Commissioner also has the powers under the Inspections Act.  

A data subject may (in addition to making a complaint to the Information Commissioner) also make a claim to the courts for compensation for material or non-material damage (which may include distress). 

5. Registration / notification / authorisation

The Data Protection Legislation does not require prior notification or registration for any data processing activities.


6. Main obligations and processing requirements

The Data Protection Law recognises two parties who deal with personal data:

  1. Data Processors: the subject or legal entity that processes personal data on behalf of the Data Controller.
  2. Data Controller: the subject or legal entity that decides on the processing of personal data.

Their relationship must be established through contractual clauses or other legal instruments in a way that proves the existence, scope and nature of such relationship.

According to the Data Protection Legislation, the principles that must be observed by controllers and/or processors in the processing of personal data are the following:

  1. Legitimacy: Personal data must be collected and processed in a lawful manner;
  2. Consent: The data subject must give its consent for the processing of its personal data;
  3. Information: Through a Privacy Notice, the Data Controller must inform the data subject about the existence and the characteristics of their personal data processing;
  4. Quality: This principle is given when the personal data is provided directly by the data subject; if not, the Data Controller must take the measurements to meet the quality principle and adopt mechanisms that are considered necessary to ensure that the data is accurate, complete, updated and correct;
  5. Purpose: Personal data can only be processed for the purposes established in the Privacy Note.
  6. Loyalty: Personal data must be processed safeguarding the protection of the data subjects’ interests and the reasonable expectation of privacy;
  7. Responsibility: Data Controllers must ensure the processing of personal data in their custody, as well as the data transferred to a Data Processor.

Additionally, the following legal requirements should be taken into account when processing personal data:

  1. Personal data must be collected and processed in a lawful manner in accordance with the provisions established by the Data Protection Legislation and other applicable regulations;
  2. Personal data must not be obtained through deceptive or fraudulent means;
  3. In all processing of personal data, it is presumed that there is a reasonable expectation of privacy, understood as the trust any one person places in another for personal data provided to be treated pursuant to any agreement of the parties in the terms established by the Law;
  4. Personal data should not be kept for any longer than is necessary in order to comply with the purposes for which the personal data was originally held. Data Controllers must establish and document retention procedures, including deletion and/or blocking of personal data, taking the nature of the data into account.   

Watch out for specifics regarding video surveillance, biometrics and employment.

7. Data subject rights

All data subjects are entitled to exercise rights of access, rectification, cancellation and objection regarding their personal data (collectively known as ARCO rights). These rights are not mutually exclusive.

Right of Access

The data subject is entitled to access its personal data held by the Data Controller, as well as information regarding the conditions and generalities of the processing.

Right of Rectification

Data subjects may request, at any time, that Data Controllers rectify personal data if it is inaccurate or incomplete.

Right of Cancellation

Data subjects have the right to cancel (i.e. seek erasure of) its personal data. There are certain situations where Data Controllers have the right to object to such erasure (e.g. if required by applicable law or public interest).

Right of Objection

Data Subjects may, at any time, oppose the processing of their personal data for legitimate purposes.

There are no substantive derogations from the EU GDPR.

8. Processing by third parties

According to the Data Protection Law, if the Data Controllers intend to transfer personal data to third parties, it must provide them with a Privacy Notice and the purposes to which the data subject has limited data processing. The data subject must consent to such transfer via the Privacy Notice.


Data Processors must obtain permission from Data Controllers if subcontracting may involve the subcontractor processing personal data. Once consent is obtained, the Data Processor must enter into a contract with the subcontractor.

The subcontractor will assume the same obligations required for Data Processors under the Data Protection Legislation and other applicable law.

The Data Processor’s right to subcontract processing activities should be outlined in the contract between the Data Controller and Data Processor. If this right is not covered in that contract, the Data Processor must seek specific consent from the Data Controller in order to subcontract processing activities.

Since the ZVOP-1 provisions on security of data still apply, the data procession agreement must lay down data processing activities and appropriate technical and organisational security measures to protect personal data; a mere reference to proper handling of personal data and compliance with the provisions of data protection legislation does not suffice.

9. Transfers out of country

International transfers of personal data must be consented to by the data subject and the purposes of such transfers must be included in the Privacy Notice. Such consent is not required where the transfer is:

  1. pursuant to a Law or Treaty to which Mexico is party;
  2. necessary for medical diagnosis or prevention, healthcare delivery, medical treatment or health services management;
  3. made to holding companies, subsidiaries or affiliates under common control of the Data Controller, or to a parent company or any company of the same group as the Data Controller, operating under the same internal processes and policies;
  4. necessary by virtue of a contract executed or to be executed in the interest of the data subject between the Data Controller and a third party;
  5. necessary or legally required to safeguard public interest or for the administration of justice;
  6. necessary for the recognition, exercise or defence of a right in a judicial proceeding; or
  7. necessary to maintain or fulfil a legal relationship between the Data Controller and the data subject.

There are no substantive derogations from the EU GDPR.

10. Data Protection Officer

Data Controllers must appoint a Data Protection Officer (or equivalent role) to deal with data subjects’ requests and promote data protection compliance within the Data Controller’s organisation.

There are no substantive derogations from the EU GDPR.

11. Security

Data Controllers and Data Processors are required to establish and maintain administrative and physical, security and, if applicable, technical measures for the protection of personal data.

In developing security measures, the data controller should take at least the following into account:

  1. the inherent risk given the type of personal data;
  2. the sensitivity of the personal data;
  3. technological developments;
  4. the potential consequences of a breach for data subjects;
  5. the number of data subjects;
  6. prior vulnerabilities in the processing systems;
  7. value of the data for an unauthorised third party; and
  8. other factors that may impact the level of risk or that result from other applicable laws and regulations.

The Data Protection Regulation also sets out actions that Data Controllers can take in order to comply with the security requirements:

  1. prepare an inventory of personal data;
  2. determine the functions and obligations of the person(s) who will process personal data;
  3. conduct a risk analysis of personal data consisting of identifying dangers and estimating the risks;
  4. establish the necessary security measures;
  5. identify gaps between existing security measures and those required for each type of data and each processing system;
  6. prepare a work plan based on the gap analysis in (v) above;
  7. carry out revisions and/or audits;
  8. train personnel who process personal data; and
  9. keep a record of the methods of processing personal data.

There are no substantive derogations from the EU GDPR, however some provisions of the ZVOP-1 still apply. For example, data controllers must adopt a general act that provides procedures and measures for the protection of personal data and determine the persons responsible for certain personal databases and persons who, due to the nature of their work, may process certain personal data. 

12. Breach notification

There are no requirements for Data Controllers to notify the INAI in the event of a data breach (other than Data Controllers which are government entities). However, Data Controllers must notify data subjects if their personal data is subject to a breach with at least the following information:

  1. nature of the breach;
  2. the personal data compromised;
  3. recommendations of actions that may be taken by the data subject to protect its interests;
  4. immediate measures being taken by the data controller; and
  5. any means by which the individual can find further information regarding the matter.

There are no substantive derogations from the EU GDPR.

13. Direct marketing

Personal data can be processed for advertising and marketing purposes in accordance with the Data Protection Legislation, provided that these purposes are made clear in the Privacy Notice and in any other medium required for communicating the processing purposes.

If by email: ZEKom-1 prohibits the use of email addresses for direct marketing purposes without the customer’s prior consent, unless:

  • the customer purchased a product or service from the person proposing to undertake the marketing;
  • the direct marketing relates to an offering of the person proposing to undertake the marketing their own similar goods or services; and
  • the customer was given a clear and explicit possibility to opt out of the use of its email address for direct marketing purposes free of charge and in a simple manner, both when their details were collected and in each subsequent marketing communication.

If by regular mail: for the purpose of direct marketing the company may use only the following data collected from the publicly available sources or in the context of the lawful pursuit of company’s activity: personal name, address of residence and phone/fax number. For any other data the company must obtain prior consent. Opt-out option must be provided to an individual by the company when performing direct marketing.

14. Cookies and adtech

When the Data Controller uses remote or local mechanisms for electronic, optical or other forms of technological communication which allow collection of personal data automatically and simultaneously to the time the data subject has contact with such communications mechanisms, the data subject must be informed about the use of these technologies, at the time the data subject makes contact with the technology and must be informed of the obtention of personal data as well as the way in which the cookies can be disabled.

Cookies and similar technologies are covered by ZEKom-1. The basic rule is that organisations must: 

  • clearly and comprehensively inform the user in advance about the data controller and the purpose of data processing in line with data protection rules;
  • get the user’s prior consent, unless the cookie is:
    • used for the sole purpose of carrying out the transmission of a communication over an electronic communications network; or
    • strictly necessary for the provision of a service explicitly request by the user.

Duration of cookies should also be specified. 

Cookies consent under ZEKom-1 means consent to the same standard as is required under the EU GDPR.

These rules will apply to adtech and online marketing that is cookies-based (whether or not personal data is used). Where personal data is processed, the requirements of the EU GDPR will also need to be complied with.

The Information Commissioner has published FAQs on the use of cookies and similar technologies.

15. Risk scale




1. Local cybersecurity laws and scope

There is currently no specific federal cybersecurity law in force in Mexico.

Cybersecurity is regulated in the Federal Criminal Code, the Data Protection Legislation and other sector-specific legislation applicable to entities operating within those sectors (e.g. the Fintech Law). Specific cybersecurity measures are normally regulated through tertiary regulatory instruments such as manuals, official operating parameters and guides.

The key cybersecurity laws that apply in Slovenia are: 

2. Anticipated changes to local laws

A National Cybersecurity Strategy document was published in 2017, but since the change in government in December 2018, there has not been much progress in terms of actual regulation.

In February 2020, a Mexican Senator submitted a bill proposing amendments to the Data Protection Law (the “DP Bill”).

The DP Bill proposed implementing best practices with respect to cybersecurity but made no specific recommendations.

There have been no developments regarding the DP Bill since it was announced in February 2020.

There is a proposal before the European Commission to update the NISD. Once the proposal is agreed and then adopted, the EU Member States will have 18 months to transpose the updated Directive into their domestic legislation.

3. Application 

There is no indication of when (or if) the DP Bill will be passed into law or if the National Cybersecurity Strategy will be progressed.

  • The NISD was implemented in Slovenia by the ZInfV. ZInfV applies to operators of essential services (OES), digital service providers (DSP), and certain state administration bodies. 
  • OES are organisations that meet certain threshold requirements and operate within the following sectors: energy, digital infrastructure, drinking water supply and distribution, health sector, transport, banking, financial markets infrastructure, food supply, environmental protection). 
  • DSP are legal entities or natural persons that provide digital services. Digital services are online marketplace, search engine and cloud computing services. 
  • ZInfV regulates, inter alia, the security of networks and information systems and measurements for achieving a high level of security of network and information systems, minimum safety requirements and requirements for reporting of incidents and operating of authorities for information security and security incidents. 
  • The ePrivacy Directive was implemented in Slovenia by ZEkom-1, and has been amended several times;
  • ZEKom-1 regulates, inter alia, electronic communications networks and services, construction of electronic communications networks, security of networks and services and their operation in emergency situations, protection of the privacy of communications right, etc. 
  • regulates electronic commerce and defines the liability of service providers and hosts for the information transmitted/stored.

ZEPEP regulates, inter alia, electronic business, including business in an e-form by using information and communications technology and use of electronic signatures in transactions.

4. Authority

The primary authority in charge of responding to any issue regarding cybersecurity is the National Guard (previously Federal Police, now formally though not materially fully integrated into the National Guard) and the Ministry of Public Security. Additional to this, there are other local authorities in some regions, such as the Police for the Prevention of Cybercrimes in Mexico City.

The INAI is responsible for overseeing data security breaches in general.

There are other authorities that could have jurisdiction regarding sector-specific cybersecurity breaches e.g. the Mexican Securities and Exchange Commission or Mexico’s Central Bank in case of cybersecurity breaches in the banking and financial sector. 

5. Key obligations 

Given there is no legislation specifically regulating cybersecurity, companies operating in sectors that do not have their own cybersecurity requirements are not subject to any particular obligations. Similarly, there is no obligation to report cyber incidents to the authorities. However, gaining access or trying to access a protected system is considered a crime in Mexico and therefore the offended party has the capacity to report the crime to Federal Prosecutors. 

With respect to personal data, under the Data Protection Legislation, every organisation must implement corrective and preventive measures to improve security and avoid the violation personal data rights.

  • Operators must establish a security plan to manage risk around the security of networks and services and to prevent and minimise the impact of security incidents.
  • Operators must notify the Agency for Communication Networks and Services of the Republic of Slovenia of breaches of security or integrity of networks.
  • Safety requirements must be considered in internal rules.
  • Use of reliable systems and equipment, ensuring technical and cryptographic security of procedures.   
  • Requirement to appoint a contact person for information security and its deputy.
  • Risk management on security of network and information system should be performed.
  • Establishment and maintenance of management system regarding security of information.
  • Reporting of incidents.

6. Sanctions & non-compliance 

Even though there is no definition of “cybercrime”, the Federal Criminal Code sanctions some behaviours that can be identified as cybercrimes, such as hacking, phishing, infections of IT systems with malware, identity theft or fraud. These illegal behaviours can be punished with prison sentences and a range of fines, depending on the severity of the crime. 

Administrative sanctions:
  • ZInfV: fine up to EUR 50,000
  • ZEKom-1: fine up to EUR 400,000
  • ZEPT: fine up to EUR 50,000
  • ZEPEP: fine up to EUR 20,000  

It is possible to be fined under both the above regulations and the GDPR/ZVOP-1 for the same incident, provided there are distinct bases for doing so (ie there is a breach of data protection law and a separate breach of the information security regulations).

Criminal sanctions:
  • imprisonment up to 15 years
  • Compensation claims in case of damages. 
  • See “Data Protection” section above.

7. Is there a national computer emergency response team (CERT) or computer security incident response team (CSIRT)? 

The authority responsible for the prevention and response of any cybersecurity issue is the National Response Centre for Cyber Incidents of the Federal Police (now formally incorporated to the National Guard) or CERT-MX. This body is in charge of preventing and mitigating any threat to technological infrastructure and operability in Mexico. Additionally, the INAI is responsible for supervising compliance with legislation regarding personal data protection.

SI-CERT (Slovenian Computer Emergency Response Team) provides a role of the national CSIRT. SI-CERT is a service of ARNES (Academic and Research Network of Slovenia).

SI-CERT provides the following activities:

  • coordination of resolving of cyber incidents;
  • technical advice on attacks, viruses and other misuse;
  • issuing of alerts for network managers and general public on current threads in electronic networks. 

SIGOV-CERT (a body within the Ministry of Public Administration) is a response centre for information security incidents in information systems of the state administration.

8. National cybersecurity incident management structure

The CERT-MX is responsible for dealing with any cybersecurity incidents, but only after a specific request, complaint or demand is submitted. The INAI can also initiate investigations regarding the protection of personal data.

Cybersecurity incidents may be reported to SI-CERT. Cybersecurity incidents within the information systems of the state administration may be reported to SIGOV-CERT.

9. Other cybersecurity initiatives 

In the private sector, the Mexican Association for Cybersecurity offers services and products regarding cybersecurity and data protection. It also encourages the protection of information and proper information handling. 

SI-CERT has been implementing awareness-raising and educational program on internet safety “Safe on the internet”: (web-page only in Slovenian).

SAFE:SI is a national internet point for raising awareness for children and teenagers on the safe use of internet and mobile devices (
