Haystack iS (iatricSystems) vs Imprivata Patient Privacy Intelligence (2026)
Both monitor staff access to patient records with machine learning. Haystack iS pulls access audit files from the record system, HR platforms and other applications into one place. Solomon, a machine learning engine iatricSystems built, learns normal access by role, department, shift and workflow, alongside rules and weights the customer can adjust. AVA, a virtual assistant, can send a flagged employee a questionnaire. Imprivata PPI, formed from the FairWarning and Maize Analytics products, watches access across the record system and other applications. Explanation based auditing ties each access to a reason, such as an encounter or appointment, and surfaces what it cannot explain. Imprivata's managed privacy service can run it. Choose Haystack iS for detection weights you tune and named record system feeds; choose Imprivata PPI for access explained against clinical reasons and a published business associate agreement.
- Your privacy team wants to adjust detection rules and weights itself.
- Audit files should come from named record systems such as Epic, Cerner and MEDITECH.
- Flagged employees should get a questionnaire automatically.
- Each access should be tied to a clinical reason before anything is flagged.
- You run Imprivata access management and want privacy monitoring alongside it.
- A managed privacy service should be able to run the monitoring for you.
