TMS Data Security Gaps That Put Your Clients at Risk

Your Security Policy Ends Where Your TMS Begins

Your organization spent months earning ISO 27001 certification. You have strict rules about company-owned devices, role-based access to your GitHub repos, and documented policies about who can touch patient data or case files. Then you decide to translate your materials into 12 languages, and all of that discipline quietly walks out the door.

Here is what actually happens when a healthcare system or government agency outsources translation: content goes into a Translation Management System (TMS), which a multi-language vendor (MLV) accesses, which subcontracts to a single-language vendor (SLV), which hands the work to a freelance translator working from a personal laptop that their teenager also uses for gaming, complete with browser extensions from unknown developers and plugins pulled from sketchy sources. That chain is not unusual. It is the industry norm.

This is not a hypothetical risk. Security researchers have documented how malware operators work: they infect as many machines as possible, then sell the harvested credentials on the dark web. If your protected health information (PHI) or pre-release legal documents were open on that translator's screen, a buyer on the dark web does not need to breach your systems directly. They wait for the alert.

Why Freelancer Dependency Is Structural, Not Lazy

Before blaming the agencies, understand the structural reality. No single office in, say, Phoenix or Milwaukee can staff full-time translators fluent in Japanese, Arabic, Somali, Chuukese, and Portuguese simultaneously. Translation volumes are uneven. Rare-language pairs might see three projects a year or thirty, with no predictable pattern. The economics force reliance on freelancers, and there is no clean fix for that. What there is, however, is a difference between freelancers working inside a controlled technical environment and freelancers with unfettered CMS edit access.

The question is not whether you will use freelancers. You will. The question is whether your vendor has replaced trust-based security policies with actual technical controls.

The Zero Trust Standard Your LSP Should Meet

Crowdin's detailed breakdown of TMS data security lays out a useful framework: stop relying on agreements and start relying on enforcement. Policies asking people not to install third-party software fail because phishing works, people forget rules, and new hires do not prioritize security they have never seen violated.

Technical controls that actually matter in a localization context:

If your current language service provider cannot describe their controls at this level of specificity, that is an answer.

What This Looks Like With PHI and Legal Documents in Rare Languages

This is where the stakes become concrete for healthcare systems and courts serving Pacific Islander populations.

Chuukese and Pohnpeian speakers are among the most underserved language communities in US healthcare. Compact of Free Association (COFA) migrants from the Federated States of Micronesia, the Marshall Islands, and Palau are heavily concentrated in Hawaii, Guam, Arkansas, and parts of the Pacific Northwest. Federal Title VI obligations require meaningful language access, which means medical consent forms, discharge instructions, and social services notices need to reach these patients in their languages.

The linguist pool for Chuukese and Pohnpeian is small. Many qualified translators and interpreters are community members working from home setups. That is not a disqualifier, but it does mean the technical controls matter even more. A community interpreter handling a cancer diagnosis or a child protective services document is working with some of the most sensitive information that exists. If their credentials are compromised and a bad actor gains access to your patient portal integration or case management system, the harm goes far beyond a data breach notification letter.

At TXLOC, every linguist working on PHI or legal documents operates under enforced 2FA, receives scoped access limited strictly to the files relevant to their assignment, and works through workflows that do not require direct CMS or EHR access. We do not route Chuukese or Pohnpeian materials through a four-layer subcontracting chain because we maintain those language capabilities directly. That is not a marketing point. It is a security architecture decision: fewer handoffs mean fewer credential exposure points.

For Title VI compliance officers, this matters too. If a breach occurs in your localization workflow and you cannot document the security controls your vendor maintained, you have a compliance exposure that extends beyond HIPAA into civil rights territory.

What to Actually Ask Your Vendor

Stop asking vendors whether they take security seriously. Everyone says yes. Ask these instead:

• Do you enforce 2FA or passkeys for all linguists, or only recommend it?
• Can you show me how translator access is scoped within your TMS?
• Do your freelancers receive direct access to our CMS, EHR, or content repos, or do they work inside a contained translation environment?
• How do you handle API token rotation and expiration?
• For rare-language pairs, how many subcontracting layers exist between your contract and the human doing the translation?

The answers will tell you quickly whether you are dealing with a vendor that has thought about this or one that is hoping a breach never happens on their watch.

If you work with populations that speak Chuukese, Pohnpeian, or other Pacific languages and want to understand how direct language capability changes the security equation, reach out to TXLOC for a conversation specific to your workflow.
