Spanish engineering, since 1998
Behind smscertificado.es there is no reseller: there is ASETEC Ingeniería de Sistemas, S.L. (registered trademark MENSATEK®), a 100 % Spanish-owned engineering firm that builds and operates its own platform from Madrid. The same technology, the same team and the same support for more than 25 years.

Our own technology, our own responsibility
We design, build and operate our platform end to end: the messaging, the sealing, the evidence custody and the API are all in-house. That lets us answer for every link in the evidential chain — and answer the phone too, because the people who support you are the people who build the service.
We work for law firms, insurers, finance companies, property managers, utilities and public bodies that need to communicate with legal effect every day, and for thousands of SMEs that only need it now and then, with the same guarantee.

Guarantees that are audited, not self-proclaimed
Each of these certifications is granted and periodically reviewed by an independent third party.
Trust Service Provider (eIDAS Regulation)
MENSATEK is recognised and audited as a provider of electronic trust services, under the supervision of the competent ministry in Spain, and appears on the trust list published by the European Commission. Check it yourself: see the European Trusted List (Spain).
ISO/IEC 27001 — Information security
The international reference in information security management: risk analysis, controls and continuous improvement, independently audited. In a service whose product is proof, data security is not an extra: it is the product. View certificate (PDF).
ISO 9001 — Quality management
Our service, support and development processes are certified under the international quality management standard. View certificate (PDF).
The provider's official documentation (practice statement, PDS, timestamping unit certificate and verification endpoints) is published under Certification Policies & Practices.
The principles we don't negotiate
The proof is sacred
Evidence is only worth something if it is intact, and intact only if nobody can touch it. Every certificate is cryptographically sealed and kept for 10 years, no exceptions.
People, not recordings
+34 910 606 161 is answered by the team that runs the platform. If your case is complex, you talk directly to someone who can solve it.
Prices in the open
Published rates, no hidden fees and no lock-in. You top up when you want and it never expires.
Data in Europe, under GDPR
We process data under the GDPR and our ISO 27001 certification, with the platform operated from Spain.
Everything in writing
Contract, certification practices and policies published and accessible. What we promise is documented before you buy.
Built to last
We have been doing this since 1998. A certificate you may need eight years from now demands a provider that still exists eight years from now.
