Key services
Services that turn scattered data into evidence.
From diagnostic to signed report, a single team is responsible for recovery, consolidation and assessments.
Assessments
Tax, fiscal, accounting and labor assessments driven by the pleading or the demand, with traceable workpapers and a signed technical report.
Data Center
The consolidated database is kept in CALMO's custody, and the CALMO team handles queries, issues reports and tracks the indicators agreed with the client.
Our approach
Four stages. You decide at each one.
The diagnostic shows what can be recovered before any larger investment. Each stage ends with a deliverable and a decision of yours.
- 01
Diagnostic
Inventory of systems, databases, servers, mailboxes and files, in read-only mode, with a risk map and a collection plan.
- 02
Recovery
Collection under chain of custody, recovery by source type and consolidation into a single database validated against the source.
- 03
Assessments
The answers that the pleading, the tax audit or the financial audit require, with workpapers traceable to the source data.
- 04
Data Center
History available for consultation: the client asks, and the CALMO team retrieves and delivers indicators and reports with the source of every figure.
Partners
Trusted partners, serving their clients in complete confidentiality.
CALMO works alongside independent auditors, law firms and accounting firms. The partner leads the relationship and the legal theory; we deliver the database, the assessment and the chain of custody that support its work.
- Confidentiality: an exclusive environment per client, restricted access and every operation logged.
- The client remains the partner's, across all service lines and new assessments.
- Joint technical responsibility of the CALMO team and the partner's specialist.
- Onboarding by the CALMO team: the partner requests the client's registration; the CALMO team handles the initial questionnaire, the power of attorney and the agreements with ICP-Brasil signatures.
Security and compliance
Evidence that stands before the judge and the tax inspector.
Every figure has a source, a date and a signature. The original is never altered, and the database is preserved, with no possibility of deletion, for 10 years — physically stored in Brazil, the United States or a sovereign datacenter within the Principality of Monaco, as the client chooses.
- Chain of custody: SHA-256 hash computed at source and checked at destination, file by file.
- Timestamps from 5 international authorities (RFC 3161) and an ICP-Brasil signature on every delivery.
- LGPD: processing limited to performing the service, under the terms agreed with the partner and the client.
Featured case study
20 years of memory recovered from discontinued systems.
An automotive retail group in southern Brazil, with 5 companies and more than 10 establishments, had its payroll and ERP on servers that had been out of operation for over 5 years. Three major lawsuits and a tax recovery depended on that data.
