Mexico's federal legislature has not enacted a standalone cybersecurity or product-security statute.
The Camara de Diputados' LeyesBiblio index of laws currently in force lists no Ley General or Ley Federal de Ciberseguridad, and the 2025 telecommunications law (Ley en Materia de Telecomunicaciones y Radiodifusion, DOF 16-07-2025, which replaced the former LFTR) carries no security-by-design, vulnerability-handling or incident-notification provision for a telecommunications, platform or software provider: that law's text does not use ciberseguridad, seguridad de la informacion or vulnerabilidad at all, and its one use of incidente is an unrelated procedural term in its sanctions chapter.
No manufacturer duty on a connected device or a product with digital elements (a pre-market security requirement, an update or support-period duty, or a vulnerability-disclosure channel) appears in any statute covered here.
A general, clocked vulnerability or incident-reporting duty running to an authority is likewise absent from primary federal legislation. Two financial-sector statutes delegate an information-security duty to secondary regulation instead of stating the operative standard themselves.
The Ley para Regular las Instituciones de Tecnologia Financiera (Ley Fintech), in the authorization-application article for an Institucion de Tecnologia Financiera (ITF, a CNBV-licensed fintech institution offering crowdfunding or electronic-payment-fund services), requires the applicant's dossier to include evidence of secure technological support and of minimum security standards assuring the confidentiality, availability and integrity of information and the prevention of fraud and cyberattacks, then hands the operative standard, audit cadence and any incident clock to disposiciones de caracter general the CNBV and Banco de Mexico issue jointly; no primary text for those disposiciones is available here.
The Ley de Instituciones de Credito, which binds banks, carries no comparable cybersecurity or information-security-programme article of its own; the only seguridad de la informacion language in that statute concerns safeguarding client-identification records under its anti-money-laundering reporting regime, not a general information-security duty, and the bank-specific cybersecurity requirements sit in the CNBV's Disposiciones de caracter general aplicables a las instituciones de credito, filed as rows of their own.
The CNBV's security and incident-reporting rules for banks and for electronic payment funds institutions are filed as rows of their own.
The one duty flagged here sits outside the financial sector, in the general consumer-protection statute rather than in a dedicated security law.
Ley Federal de Proteccion al Consumidor (LFPC) Arts. 76 Bis and 76 Bis 1, added to that statute in 2000 and unchanged in the relevant fractions through the DOF 14-11-2025 reform, bind any proveedor conducting a transaction with a consumidor through medios electronicos, opticos o de cualquier otra tecnologia: the provider must use an available technical security element to protect the confidentiality of the information the consumer provides, and it must follow the Secretaria de Economia's Norma Mexicana for electronic commerce, whose required content the statute itself specifies must include reliable technical security mechanisms guaranteeing the protection and confidentiality of the consumer's personal information and of the transaction.
Procuraduria Federal del Consumidor (PROFECO) enforces it administratively under the LFPC's general fine bands; no criminal offence or distinct private right of action attaches to this chapter.
Mexico's breach-notification duty for personal data, LFPDPPP Arts. 18 and 19 (a controller must establish and maintain administrative, technical and physical security measures, and inform the data subject immediately of a security breach that significantly affects their patrimonial or moral rights), sits in the privacy topic and is not restated here: it is the comprehensive data-protection act's own security-of-processing clause rather than a standalone security statute, which is the line this topic draws against privacy.
Article 168 Bis 12, section III of the Comisión Nacional Bancaria y de Valores general provisions for credit institutions requires an annual calendar of vulnerability-scanning tests of infrastructure components. Article 168 Bis 16 of those provisions requires a credit institution to make its information security incidents known to the Commission immediately by email.
Article 33 of the CNBV and Banco de México provisions for electronic payment funds institutions requires a security evaluation or audit of the technological infrastructure at least once a year. Article 42 of those provisions requires an electronic payment funds institution to make its information security incidents known to Banco de México and the CNBV immediately.
