Healthcare cybersecurity
for the AI attack era

Attackers can now run capable AI with its safeguards removed on hardware they control. SofTx helps Canadian hospitals, imaging networks, clinics, and health-tech teams find and fix the gaps first, from PACS and HL7 interfaces to the AI you are deploying.

Why now

The attacker's clock has changed

AI has shortened the time attackers need. It has not shortened the time a hospital needs to patch a system that is delivering care.

Cybercrime threat

Ransomware is the top cybercrime threat facing Canada's critical infrastructure, including healthcare.

Attack surface

Where hospitals are actually exposed

Clinical environments have risks that general IT security programs often overlook.

PACS and imaging archives

Ontario's privacy commissioner documented an imaging clinic likely breached through a dormant admin account. The attackers deleted its backups, up to 550,000 patient records may have been affected, and the clinic temporarily closed.

HL7 and FHIR interfaces

Interface engines connect nearly every clinical system. Classic HL7 v2 feeds have no built-in authentication or encryption, so anyone who reaches that network segment can often read or alter messages.

Identity and vendor access

Stale accounts, shared service logins, and always-on vendor VPNs are easy for automated tools to find. They often lead straight to clinical systems.

Clinical AI and LLM tools

Scribes, chatbots, and retrieval tools add new paths to patient data, including prompt injection, over-broad record access, exposed model servers, and unapproved tools staff adopt themselves.

Medical and facility devices

Winnipeg's Health Sciences Centre reported a 2026 ransomware incident affecting facility maintenance systems. Reports said doors and HVAC were affected, while patient care continued.

Shared IT and suppliers

In 2023, ransomware at a shared IT provider forced five Ontario hospitals to shut down internal systems and delayed patient care. Your exposure includes your suppliers' exposure.

What we do

Healthcare cybersecurity services

Security work from a team that also builds and integrates healthcare software.

AI-era exposure assessment

We map internet-facing systems, PACS, interfaces, vendor connections, and AI tools, then rank what an automated attacker would reach first and what would hurt care most.

Application and integration testing

Authorized security testing of patient portals, clinical apps, APIs, FHIR services, DICOM endpoints, and the custom integrations generic scanners tend to miss.

Clinical AI security

Reviews of LLM and imaging AI deployments for prompt injection, record-level access control, model supply chain, logging, and unapproved AI use.

Fixes, not just findings

We are software engineers, so an assessment doesn't have to end with a PDF. We can patch the code, harden the integration, and verify that the fix holds.

Ransomware readiness

Timed restores from offline backups, tested downtime procedures, and tabletop exercises with clinical and executive leaders before a real incident.

Compliance evidence

Practical support for cyber security maturity assessments, PHIPA safeguards, and vendor reviews, working alongside your privacy office and legal counsel.

Proactive security

Reactive versus proactive

Most of what limits the damage in a healthcare incident has to be in place before it starts.

Reactive

Proactive

Patches wait for the next maintenance window

Exposed systems follow a faster, risk-ranked patch schedule

Backups are assumed to work

Offline restores are tested and timed

Dormant accounts are found during the investigation

Dormant and vendor accounts are reviewed and removed regularly

The first downtime drill is the real incident

Clinical leaders have already rehearsed it

AI tools appear without a security review

Every model, endpoint, and data path is inventoried and tested

How we work

Map, test, fix, rehearse

A repeatable cycle, because your systems and the threat will both keep changing.

  1. 01

    Map

    Inventory the systems, data flows, suppliers, and AI tools that clinical care depends on.

  2. 02

    Test

    Run authorized testing within agreed clinical safety limits, including AI-assisted attack paths.

  3. 03

    Fix

    Close the highest-risk gaps first, with engineering work your team can maintain.

  4. 04

    Rehearse

    Test restores and incident response, then retest as your systems and the threat change.

Canadian obligations

Built around Canadian requirements

Security work should also leave you with the evidence regulators and boards expect.

Ontario EDSTA, O. Reg. 51/26

In effect since July 1, 2026 for Group A, B and C public hospitals and the University of Ottawa Heart Institute: named contacts, maturity assessments every two years, and 72-hour reporting of critical incidents.

PHIPA and provincial health laws

Health information custodians must protect personal health information and notify patients and regulators of certain breaches. Requirements vary by province, so we map yours first.

PIPEDA

Private-sector organizations covered by PIPEDA, including many health-tech vendors, must report breaches that create a real risk of significant harm.

AI-driven threats, Canadian rules, and how we test safely in clinical environments.

Ask us something else

It finds and reduces the risks specific to clinical environments: exposed PACS and DICOM services, HL7 and FHIR interfaces, vendor remote access, medical and facility devices, and AI systems handling patient data. SofTx adds software engineering to that work, so the code and integrations behind a finding actually get fixed.

Public threat reports from Google and Anthropic describe attackers using AI agents for reconnaissance, phishing, credential harvesting, and exploit development, often with people only choosing targets and reviewing results. In healthcare, the practical effect is less time between a public security fix and a working attack, while hospitals still patch around clinical schedules.

Anyone can download an open-weight model and run it privately, outside any provider's monitoring, and its safety training can be removed. NIST's CAISI called GLM-5.3 the most cyber-capable open-weight model released to date. Open weights are not the problem on their own, and defenders use them too, but hospitals should assume attackers have this capability.

Since July 1, 2026, Group A, B and C public hospitals and the University of Ottawa Heart Institute must designate cyber security contacts, complete a cyber security maturity assessment every two years and submit a summary, and report critical incidents to the provincial CISO within 72 hours of confirmation. We help teams prepare the evidence; your legal counsel should confirm how the rules apply to you.

It has to be planned that way. Scope, timing, and stop conditions are agreed with your clinical and IT leads before any testing starts. Intrusive tests run against non-production copies or in approved windows, and we do not run destructive tests against systems that are delivering care.

Yes. Self-hosting can be one of the strongest options for keeping patient data inside your network. It needs the same care as any clinical system: verified model sources, no open internet access, tightly scoped tools, patient-level access controls on retrieved records, and full logging.
