Haystack iS (iatricSystems) vs Protenus (2026)
Both monitor insider access to PHI, and both grade A on integration, so scope and governance decide it. Protenus is the broader platform: privacy monitoring and drug diversion surveillance run on one behavioural engine, and it holds Best in KLAS in both domains, so a single purchase covers the privacy office and the pharmacy at once. Haystack is privacy only, but it brings the deepest integration estate in the category, more than 180 named systems plus an open audit file path, and the most careful published posture on the thing these products get wrong: it frames a flag as a reason to look again rather than a finding, lets customers set the risk weights, and publishes the diligence questions buyers should ask of any AI vendor. That earns it a B on governance where Protenus sits at C for profiling clinicians with no published fairness evaluation. If your failure mode is covering privacy and diversion together with independent validation in both, start with Protenus. If your failure mode is integration reach and a more careful hand on workforce surveillance, start with Haystack, and scrutinise its automated outreach to flagged staff.
- The deepest integration estate in the category, graded A: named support across Epic, Cerner, MEDITECH, Allscripts, athenahealth, and Quadramed among more than 180 vendors, plus an open audit file import specification, backed by 35 years of integration work across a reported 1,300 plus hospitals.
- The strongest published PHI stewardship posture in the lane, graded A: the company publishes the diligence questions organisations should ask of any AI vendor, including itself, on data flow, retention, and BAA terms, rather than simply asserting compliance.
- A more careful governance posture on workforce surveillance, graded B against Protenus at C: a flagged access means behaviour differed enough for a second look, not that it was inappropriate, and customers set the event weights themselves.
- Two risk domains from one platform: patient privacy monitoring and drug diversion surveillance share one behavioural engine, so a single purchase covers both the privacy office and the pharmacy, where Haystack is privacy only.
- The clearest AI necessity case in the category, graded A on AI centrality: moving from sampling a tiny fraction of accesses to 100 percent coverage of accesses and medication transactions is only possible with automated behavioural analysis, protected by granted patents.
- Independent validation in both domains, graded B on evidence: Best in KLAS in 2023 for both patient privacy monitoring and drug diversion surveillance, rare to win in two categories at once, plus Gartner Cool Vendor recognition.

Side by Side
Each record in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached. Generated from this pair’s live capability grades, so it moves when a grade moves.
The AI Health Index awards Haystack iS (iatricSystems) its top capability grade on AI Safety and PHI Stewardship and EHR and Interoperability Depth. Set against Protenus, Haystack iS (iatricSystems) grades higher on AI Safety and PHI Stewardship and AI Governance and Bias Disclosure. Grades reflect evidence the AI Health Index could verify at the last review, so a low grade records disclosure the vendor has not published rather than a capability it has been shown to lack.

Questions buyers ask
Should we choose Haystack iS (iatricSystems) or Protenus?
On the axes where the AI Health Index separates them, Haystack iS (iatricSystems) grades higher on AI Safety and PHI Stewardship and AI Governance and Bias Disclosure, and Protenus grades higher on AI Centrality and Model Supply Chain Disclosure. Neither leads on the greater share of scored axes, so the decision turns on which constraint is binding rather than on an overall winner.
Where do Haystack iS (iatricSystems) and Protenus differ most?
The widest separation the AI Health Index records between Haystack iS (iatricSystems) and Protenus is on AI Safety and PHI Stewardship, where Haystack iS (iatricSystems) grades A and Protenus grades B. That axis sits in the AI Capability group, so it should carry the most weight for a buyer whose binding constraint is how much of the work the model itself is trusted to do.
Where do Haystack iS (iatricSystems) and Protenus grade the same?
The AI Health Index grades Haystack iS (iatricSystems) and Protenus the same on several axes, including Autonomy and Oversight Model, Model and Technology Transparency and Clinical and Operational Evidence. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.

Both grade A on interoperability, so the split is scope and governance. Protenus covers privacy and diversion from one platform and holds Best in KLAS in both, an evidence position Haystack, graded B with no KLAS ranking located, does not match. Haystack is privacy only but carries the deepest integration estate and the strongest published PHI stewardship disclosure in the lane.
On governance the grades diverge, Haystack B against Protenus C: Haystack frames a flag as a reason for a second look rather than a finding and lets customers control the risk weights, where Protenus builds behavioural profiles of named clinicians with no published fairness evaluation or false accusation rate. Both are workforce surveillance products where an alert can trigger investigation, licensure referral, or prosecution, so that governance difference is substantive. One Haystack caution: its AVA assistant contacts a flagged employee directly before a human has necessarily reviewed the case. Neither publishes a security attestation or pricing.
