ISI Language Solutions

What ISI Language Solutions does

ISI Language Solutions is a privately held, Atlanta-based provider of professional translation and interpretation services, founded in 1974 and operating as a subsidiary within the BIG Language Solutions LLC portfolio. The company delivers document translation, localization, and interpretation across more than 300 languages and dialects to enterprise and mid-market B2B customers in regulated and highly technical verticals — primarily medical/healthcare and intellectual property/legal, with secondary focus on life sciences, manufacturing, insurance, education, government, health insurance, and financial services. Its core differentiator is a security- and compliance-led service model built around LanguageVault®, a proprietary secure translation environment marketed as 'The World's Most Secure Translation Environment™,' supplemented by LanguageExpress™ for HIPAA-compliant healthcare interpretation.

The underlying delivery model pairs platform tooling with human expert linguists (the BIG portfolio claims 15,000 linguists across 26 global locations) and holds HITRUST CSF, ISO 17100, HIPAA, and GDPR credentials to gate access to regulated buyers. Service breadth spans on-site, over-the-phone (OPI), and video remote (VRI) interpretation; document and certified translation; website, eLearning, voiceover, subtitling, and transcreation work. Quantitative operational metrics include a 20-second average interpreter connect time, 99.999% telephony uptime, and a 10-point quality assurance checkpoint process.

ISI generates revenue primarily through professional services engagements (translation, localization, on-site interpretation) priced on a quote basis and through usage-based per-minute billing for OPI/VRI (billing starts only after interpreter connection). GTM is enterprise field sales with consultative, industry-specialized engagement, supported by content marketing across a blog, YouTube, LinkedIn, email, and social channels, and a bottom-of-funnel 'Free Quote' CTA. The company is one of five retained brands (Protranslating, BIG-IP, Language Link, DWL, Law Linguists) within BIG Language Solutions, which has executed roll-up acquisitions including DWL in 2021 to extend UK and life-sciences reach.
