How it works
1
Your client or applicant connects their RFC with their CIEC password or e.firma (or you send them an invitation from Atlas).
2
Atlas extracts and processes their SAT information.
3
Your system receives it via API, alongside the dashboard, PDF and Excel.
Who it's for
Financial institutions
Loan origination and portfolio monitoring.
ERPs and platforms
Embed SAT tax data in your own product.
Accountants with many RFCs
Monitor every RFC from your own system.
Security
Read-only
Atlas reads and downloads; it never files, signs or changes anything with the SAT.
Credentials
SAT passwords and e.firma files are encrypted in a secrets vault; nobody on the team sees them in plain text. Lenders never see their applicants' credentials.
Encryption
TLS on every connection and data encrypted at rest.
Infrastructure
Microsoft Azure with private networks, backups and continuous monitoring.
Frequently asked questions
Do I need my client to give me their password?

How much does it cost?
