Collections & Claim Processing for HealthCare
Healthcare is a major industry with different players in the ecosystem. Organizations outsource most of the services to third-parties such as collections and claim processing services. With HIPAA enforcement and fines hitting the news headlines, organizations need to be more careful about where PHI extends beyond their perimeters.

AMCA’s breach led to the exposure of patient names, dates of birth, addresses, phone numbers, dates of service, providers, and balance information as well as credit card and bank information.

Data Centers & Hosting Providers
Many companies use cloud services to store sometimes sensitive data and perform cloud-based applications. They also leverage hosting providers to manage their websites.
Although cloud and hosting providers are usually secure, sometimes misconfiguration of servers or cyber attacks expose sensitive data.
- Image-I-Nation Technologies, a third-party providing software and hosting services to Equifax, Experian and TransUnion have been breached. The attack took place through unauthorized access to the software firm’s database containing personal information. The exposed data possibly included Social Security numbers, names, dates of birth and home addresses.
