Security & compliance
Replace VBA macros with Python services
We swap risky VBA code for hardened Python scripts so malware risk disappears, every change is versioned in Git, and runtime evidence is collected automatically—no spreadsheets or manual logs.
Python runtime
Zero macro malware
Python eliminates the exploit surface that VBA macros expose.
Audit trail
Change control via Git
Every modification is reviewed, approved, and timestamped in Git history.
Observability
Hardened execution
Services run in secured environments with logging and monitoring baked in.
| Control | VBA Reality | Python Replacement |
|---|---|---|
| Code provenance | Anyone with the file can edit macros, no signing or traceability. | Signed containers plus full Git history track who changed what. |
| Access & permissions | Document passwords, exceptions, and shared drives. | OIDC/AD RBAC, audit logs, and just-in-time secrets issuance. |
| Change & approvals | Copy/paste changes with no formal process or review. | Pull requests, automated tests, and approvals before release. |
| Malware risk | Macros often require dangerous exceptions that attackers can abuse. | No macros to maintain plus SBOM and EDR coverage on every runtime. |
| Data residency | Local drives and email attachments with no retention policy. | Regional clusters with encryption at rest and governed retention. |
Encryption
AES-256 for every client workbook stored at rest. Data stays protected even when it is not active or “in motion”.
Change lineage
Git history plus automated changelogs prove who touched critical logic and when approvals happened.
Zero-trust ready
Services ship with API identities, network policies, and no manual evidence collection.
