Business Data Privacy by Design
Your client list, your contracts, your patient and payment records — every one becomes a liability the second an AI tool copies it to a server you don’t own. Privacy policies you didn’t write now govern your most sensitive data. Business data privacy by design means the AI never gets to copy anything off-site, because the AI lives in-house.
Retained “to improve their service”
Cloud AI vendors retain inputs “to improve their service” — which means your customer records may train someone else’s model or sit in someone else’s backups.
For firms handling health, financial, or legal data, that’s a compliance and trust problem, not just an IT one.
Privacy by design
The architecture itself prevents export: in-house model, in-house storage, no vendor API in the path.
Compliance-friendly setup
Controls that support HIPAA and PCI workflows — access control, audit logs, data residency in your building. We configure; your auditor certifies.
Data residency you can point to
Your data physically sits on a server in your office in Texas, not an unnamed region.
You set retention
Nothing is kept “to improve a service.” Deletion and retention are your policy, enforced on your hardware.
Where your data ends up
Public AI tool
Your records → vendor cloud → vendor backups → vendor training set (maybe) → unknown staff access.
TIS in-house AI
Your records → your server → your locked room → your logs → your people only.
Handling private documents at scale is document automation, kept in-house. This is part of our main private AI infrastructure work.
Keeping records in-house across Missouri City and Rosenberg
Medical, financial, and legal practices in Missouri City and Rosenberg can keep the records the AI reads on a server in their own office — data residency you can literally walk over and point at. See our Texas service areas.
Data privacy questions
Does using in-house AI make us HIPAA or PCI compliant?+
It supports compliance by keeping data on-prem with audit logs and access control; certification still comes from your auditor — we don’t claim to certify you.
Where does our data physically live?+
On a server in your office. You can walk over and point at it; there’s no third-party region involved.
Can a cloud AI vendor really use our data?+
Many retain inputs per their terms, sometimes to train models. In-house AI removes that question entirely.
Who can access the data the AI uses?+
Only the people you grant access on your network; access is logged on your hardware.
What about data we’ve already sent to cloud tools?+
We can’t recall that, but we can stop the leak going forward and audit what’s exposed with our Data-Privacy Checklist.
How is retention handled?+
You set it. Nothing is kept beyond your policy, and deletion happens on the box you own.
Does the Texas Data Privacy and Security Act apply to my small business?+
In most cases, no — the TDPSA (effective July 1, 2024) largely exempts small businesses as defined by the U.S. Small Business Administration. The main carve-out is that even an exempt small business still needs consent before selling sensitive personal data. This is general information, not legal advice; confirm your status with your own counsel. Our AI compliance for Texas businesses guide goes deeper.
Where exactly do my encryption keys live?+
On hardware you own, under your control — not in a vendor key service. We treat AES-256 at rest and TLS 1.3 in transit as the default on a build, and key management (where keys are stored, how they rotate, who holds them) is configured so the encryption stays meaningful. Our encryption for private AI guide covers key custody in detail.

Where TIS stops — the honesty boundary
TIS builds and installs private AI infrastructure that supports your compliance program — on-premise data, encryption, access control, and audit logging. We are not auditors, assessors, or attorneys, and we do not certify your organization. Your QSA, CPA, C3PAO, or counsel handles certification and legal sign-off.
Which infrastructure control supports which framework
A private build provides the technical controls a compliance program leans on. The table maps the controls we configure to the frameworks a Texas business actually faces — as support, never certification.
| Framework | Who it applies to | Infrastructure controls that support it |
|---|---|---|
| HIPAA Security Rule | Practices and vendors handling ePHI | On-prem PHI, encryption at rest/in transit, access control, audit logs (commonly kept 6 years). |
| PCI-DSS 4.0 | Anyone handling cardholder data | VLAN segmentation away from the card environment, TLS 1.3, MFA, access logging. |
| SOC 2 | Service providers proving controls | Access control, encryption, and immutable logs that feed the CPA's examination evidence. |
| CMMC 2.0 / NIST SP 800-171 | DoD contractors handling FCI/CUI | No outbound egress, encrypted storage, RBAC, immutable logging aligned to 800-171 controls. |
| TDPSA (Texas) | Larger Texas businesses (small businesses largely exempt) | Data residency in Texas, retention you set, deletion on hardware you own. |
The HIPAA proposal published as an NPRM in January 2025 would tighten encryption and MFA expectations, but it is not yet final — we treat AES-256 and TLS 1.3 as best practice today, not as a current mandate. For the full breakdown, see our AI compliance for Texas businesses guide.
Data residency in Texas
Data residency is simply the answer to "where does my data physically live?" With a cloud AI tool it is a region you do not choose and cannot point at. With a private build it is a server in your office — you can walk over and put a hand on it. That physical location is the foundation everything else sits on: the documents the AI reads, the vector store it searches, the logs it writes, and the backups all stay in the building. You set retention and deletion, and they are enforced on hardware you own rather than on a vendor's schedule.
Residency works hand in hand with encryption: the data stays in Texas and it is protected on disk and on the wire, with keys you control. See how we handle at-rest, in-transit, and key custody in our encryption for private AI guide, and how residency feeds a compliance program in our AI compliance for Texas businesses guide.
