Do you know where your employees are keeping your company's digital certificate?
For freelancers, small agencies, and SMBs, the digital certificate is the absolute key to their business: it allows signing contracts, requesting grants, and accessing tax data. The problem arises when this critical file ends up installed on the browsers of three different laptops, shared via WhatsApp, or exposed in an external accountant's download folder. A single human error or a conflictive employee departure can legally paralyze the company or cause catastrophic unauthorized access.
The Trap of Local Installation
Most small businesses choose to export the basic file along with its password so their team can perform daily procedures. This invalidates any audit trail, makes it impossible to revoke access immediately, and leaves the corporate signature unprotected against trojan-type malware. Delegating your company's legal signature to local browsers is a cybersecurity Russian roulette.
Our Solution: Cloud API for Custody and Centralized Signing
At LANZA ESTUDIO, we develop a cloud infrastructure that allows storing the digital certificate in a high-security encrypted container, exposing a private API that controls who, when, and for what purpose can use the electronic signature, without anyone having physical access to the original file.
- Encrypted Key Vault: Total isolation of the certificate in a secure cloud environment that prevents direct download of the cryptographic file.
- Secure API Consumption: The SMB's applications or management software perform the signature by calling an endpoint protected by single-use tokens.
- Real-Time Access Audit: An immutable registry of every executed signature, identifying the specific team member who launched the request.
- Immediate Permission Revocation: The ability to cut off access to any collaborator with a single click from a centralized dashboard, without needing to change the certificate.
The Real Impact on Operational Security
- Zero Leakage Risks: The original file never leaves the cloud vault, completely blocking unauthorized copies by employees or third parties.
- Procedure Automation: The capacity to connect the API with billing or management scripts to automatically sign massive batches of documents.
- Absolute Legal Peace of Mind: Strict compliance with European security directives without hindering the daily workflow of your collaborators.
