Common questions
Clarity,
from the start.
A closer look at working with Tallia, and how we treat the information you entrust to us.
Talk to our teamWhat can I expect from a demo?
A 30-minute walkthrough on a real question from your team. No deck. We’ll run it live against your authorities.
What counts as my data?
Two things: the documents you upload, and the questions and answers that pass through the platform. Both are treated as confidential customer data and protected the same way.
Do you train models on my data?
No. We contractually prohibit training, fine-tuning, or model improvement on your inputs, outputs, or documents — including by our model providers, who operate under zero-data-retention terms.
How is my data protected?
Tallia is ISO 27001 certified and SOC 2 Type II audited, both assessed independently. Behind that: encryption in transit (TLS 1.3) and at rest (AES-256), role-based access on a least-privilege basis, logical separation between every customer, and continuous monitoring across infrastructure and application.
Who controls access to my data?
Access follows least privilege and is gated by SSO/SAML, enforced MFA, and role-based permissions you manage. Every query and draft is captured in an audit log you can stream to your SIEM.
What happens to my data if we leave?
You can delete data at any time, and on offboarding everything is hard-deleted within 30 days.
