Cloud vs Offline: Security Trade-offs

Attack Surface

Cloud tools add a server, network transmission, and cloud storage to the attack surface. Offline tools eliminate all three.

Zero-Trust Model

In a zero-trust security model, sending files to third parties violates the principle of least privilege. Offline tools are inherently zero-trust.

Compliance

Many compliance frameworks (HIPAA, PCI-DSS, SOC2) restrict third-party data sharing. Offline tools help maintain compliance naturally.

Performance

Offline processing eliminates network latency and upload time. Local processing is typically 10-100x faster for small to medium files.
