Top 5 most secure localization tools for healthcare

1. Lokalise: the best healthcare localization tool for governed, audit-ready workflows

Lokalise is the most secure localization tool for healthcare. It’s perfect for teams that need traceable translation workflows across medical software, patient apps, and device documentation.

It’s used by highly regulated industries already, and pairs enterprise-grade security (SOC 2 Type II, ISO 27001/27017, encryption in transit and at rest) with tight control over access, workflows, and audit logs for the enterprise plan.

For GxP-aligned translation, Lokalise gives you a clearly defined, repeatable workflow. Roles and approvals are explicit, each change to clinical or device-facing content is logged, and you can trace strings across environments when auditors ask for evidence. 

Who is Lokalise for

Lokalise is the best localization platform for healthcare and life sciences teams that need governed, audit-ready localization for:

• Patient and clinical apps (telehealth, remote monitoring, e-prescription tools)
• Patient portals and onboarding flows
• Medical device UIs and instructions for use (IFUs)
• Help centers and knowledge bases for patients and clinicians

Notable healthcare customers using Lokalise include Maven Clinic, Kry, Withings, Doxy.me, and more.

With AWS backing Lokalise, I had complete confidence in their reliability and performance. As the technical lead, it was critical for me to choose a localization platform that could meet our enterprise-grade expectations, ensuring our members always have seamless access to the care they need. Lokalise has exceeded those expectations. 

Nate Powers, Software Engineer at Maven Clinic.

Why choose Lokalise for medical software localization

There are three main reasons why Lokalise is a great localization platform for healthcare:

• Security, compliance, and data governance
• Healthcare-ready workflows and integrations
• Reliable AI translation capabilities for regulated content

With Lokalise, you get enterprise security posture. This includes SOC 2 Type II and ISO 27001/27017 certifications, plus encryption in transit and at rest, aligned with GDPR and healthcare-grade security expectations.

Additionally, role-based access and scoping help you ensure only the right people and vendors can access PHI-adjacent or safety-critical strings. With full audit trails, you get access to version history, status changes, and activity logs per string, which support GxP validation requirements.

Here’s what to expect in terms of healthcare-ready workflows:

• Dedicated workflows for regulated content: Separate steps for translators, in-country medical reviewers, and legal or regulatory sign-off.
• Status-based quality gates: Customizable statuses (draft, translated, reviewed, verified) to lock content before it reaches production.
• Deep integrations with design and dev tools: Figma, Git, CI/CD, and CMS integrations keep app and documentation copy in sync without manual copy-paste, reducing operational risk.

This makes Lokalise a practical “system of record” for multilingual healthcare content that has to stay in sync across apps, portals, and PDFs.
 

Pricing

Lokalise has a 14-day free trial available. Paid plans start from $144/month, paid annually.

Lokalise uses a usage-based model (capacity over seats), with paid tiers that add more automation, governance, and analytics. Standard AI translations are included on paid plans, while Enterprise tiers are designed for regulated workloads that need:

• Custom security and compliance commitments
• More complex approval workflows and audit needs
• Higher translation volumes across multiple products and markets

In practice, this means smaller digital health teams can start quickly on lower tiers, while hospitals, large health systems, and life sciences organizations typically run on Enterprise, where they can align Lokalise with their security, legal, and validation requirements.

2. Smartling: Healthcare translation with bundled services

Smartling is a translation platform and language service provider with a growing focus on healthcare and life sciences. It combines a cloud TMS, Neural MT Hub, and managed translation services to help teams translate clinical trial materials, pharmaceutical content, and medical communications at scale.

From a compliance angle, Smartling leans heavily on its certifications: SOC 2 Type II, HIPAA and HITRUST, PCI DSS Level 1, plus ISO 17100, ISO 9001, and ISO 13485 for language services. This makes it attractive for organizations that expect strong platform security and certified life-sciences translation workflows.

Who is Smartling for

• Smartling works best for healthcare and life sciences teams that want a mix of technology and services in one vendor, for example:
  Pharmaceutical and clinical research organizations translating clinical trial documentation, patient-facing materials, and regulatory submissions
• Medtech and device companies
• Larger healthcare providers that prefer to rely on an external language services team rather than building an in-house vendor network

Smartling is a solid option if you want an AI-enabled translation management system plus a full-service translation partner. Teams that prefer to own their localization stack and keep it tightly embedded into product and engineering workflows often lean toward a platform like Lokalise instead.

Smartling’s healthcare customers include the Butterfly Network and British Medical Journal.

Why choose Smartling for healthcare localization

Smartling is a strong option for healthcare and life sciences teams that want a single vendor for both technology and translation services. Here’s why some organizations choose Smartling for regulated medical and healthcare content:
