WellSky is the home health and therapy platform that serves more large and mid-size agencies than any other in the country. Its clinical workflow depth, scheduling integration, and billing capability make it operationally strong. Its security posture at the application and infrastructure level is legitimate — WellSky maintains enterprise-grade cloud security and provides a Business Associate Agreement that covers the platform. The conversation I have with WellSky-using agencies consistently turns on the same misconception: that WellSky's BAA means WellSky is handling their HIPAA compliance. It does not. It means WellSky is handling HIPAA compliance for the WellSky application. The rest is the agency's responsibility.
The "rest" encompasses the majority of the attack surface where home health breaches actually occur. The WellSky application has never been the point of entry in a home health agency breach that I have investigated. The email accounts that receive WellSky notifications have been. The devices that field nurses use to access WellSky have been. The credentials that clinical staff chose for their WellSky logins, and reused across personal accounts that were subsequently breached on consumer websites, have been. Every home health agency using WellSky needs a security layer that protects the environment around the platform.
The WellSky Security Boundary: What the BAA Covers
WellSky's Business Associate Agreement covers the WellSky application and the cloud infrastructure that WellSky manages to run it. This includes: the servers and databases that store patient data within the WellSky environment; the network connections between WellSky's infrastructure components; the WellSky application's authentication mechanisms (username and password login, and MFA if configured through WellSky's native settings); the encryption of data stored within the WellSky database; and the WellSky audit logging of user activity within the platform. It does not cover anything that happens outside the WellSky application boundary — which is where most of the risk lives.
Layer 1: Device Security for Every WellSky Access Point
Every device that connects to WellSky — from clinical supervisor laptops to field nurse tablets to personal smartphones running the WellSky mobile app — is an ePHI access point that the agency must secure. The 2026 HIPAA mandatory requirements apply to each device: behavioral EDR must be installed and reporting, full disk encryption must be verified and documented, and MDM enrollment must be confirmed with compliance policies enforced.
WellSky's mobile application for iOS and Android is a particularly important focus area. Field nurses who use WellSky Mobile on personal smartphones are accessing patient care data in uncontrolled environments — patient homes, vehicles, public spaces — on devices the agency may never have inventoried. MDM container management for the WellSky mobile app isolates clinical data from personal apps on the device, enforces encryption for the container specifically, and enables remote wipe of clinical data without accessing personal content. Every device running WellSky Mobile should be enrolled in MDM with these controls active before clinical data access is permitted.
