The Evolving Healthcare Cybersecurity Panorama
Healthcare organizations face unprecedented cybersecurity challenges in 2025. With operational expertise (OT) environments more and more focused and the convergence of IT and medical methods creating an expanded assault floor, conventional safety approaches are proving insufficient. In keeping with latest statistics, the healthcare sector skilled a record-breaking 12 months for information breaches in 2024, with over 133 million affected person data uncovered. The common value of a healthcare information breach has now reached $11 million, making it the most costly trade for breaches.
What’s modified dramatically is the main focus of attackers. Now not content material with merely extracting affected person data, cybercriminals at the moment are focusing on the precise gadgets that ship affected person care. The stakes have by no means been larger, with ransomware now representing 71% of all assaults towards healthcare organizations and inflicting a mean downtime of 11 days per incident.
New Regulatory Frameworks Demand Enhanced Safety Controls
Healthcare organizations now face stricter regulatory necessities that particularly mandate community segmentation. The up to date HIPAA Safety Rule, printed in December 2024 and anticipated to be applied shortly, has eradicated the excellence between “addressable” and “required” implementation specs. All safety measures, together with community segmentation, will turn out to be obligatory necessities somewhat than non-obligatory issues.
Beneath part 45 CFR 164.312(a)(2)(vi), healthcare organizations should now implement technical controls to section their digital data methods in a “affordable and acceptable method.” This implies creating clear boundaries between operational and IT networks to cut back dangers from threats like phishing assaults and forestall lateral motion inside networks.
Equally, HHS 405(d) tips now present voluntary cybersecurity practices that particularly advocate community segmentation and entry controls to restrict publicity and defend important methods and information. These laws replicate the rising recognition that in as we speak’s interconnected healthcare surroundings, primary safety measures are not non-obligatory however important for shielding digital Protected Well being Info (ePHI).
Bridging the Hole Between IT Safety and Medical Machine Groups
Some of the important challenges in healthcare safety is the normal divide between IT safety groups and scientific engineering/biomedical groups accountable for medical gadgets. Every group operates with completely different priorities, experience, and operational workflows:
IT safety groups concentrate on vulnerability administration, safety coverage enforcement, and compliance reporting, whereas scientific engineering groups prioritize machine performance, affected person security, and medical gear uptime.
This divide creates blind spots within the safety posture of healthcare organizations. Scientific gadgets typically run proprietary or legacy working methods that can’t assist conventional safety brokers. In the meantime, biomedical groups keep separate stock methods that do not talk with IT safety platforms, creating visibility gaps for unmanaged gadgets.
Aaron Weismann, Chief Info Safety Officer at Major Line Well being, describes this problem: “We have now a really tough time dealing with non-traditional compute due to not having tooling particularly designed to handle and handle these gadgets. So Elisity actually supplies a layer of protection and menace mitigation that we would not in any other case have in the environment.”
The Built-in Elisity and Armis Resolution: A Complete Method
The mixing between Armis Centrix™ and Elisity’s microsegmentation platform creates a strong safety framework that addresses these challenges head-on. By combining complete asset intelligence with Elisity’s dynamic microsegmentation capabilities, healthcare organizations can obtain true zero-trust structure whereas sustaining operational effectivity.
Complete Asset Discovery and Intelligence
The built-in answer supplies unmatched visibility throughout all related gadgets—managed, unmanaged, medical, and IoT—with out requiring brokers or disruptive scanning. Leveraging an Asset Intelligence Engine containing data of over 5 billion gadgets, the answer mechanically discovers and classifies each machine on the community, together with people who conventional safety instruments miss.
The platform detects and profiles gadgets starting from infusion pumps and MRI machines to constructing methods like HVAC models—something related to the community. For every machine, the answer identifies important data resembling make, mannequin, working system, location, connections, FDA classification, and threat components.
As Weismann notes, “Armis and Elisity have actually been capable of drive extra sturdy understanding of our safety posture and the way we’re implementing insurance policies throughout the board.”
Identification-Based mostly Microsegmentation
Elisity delivers identity-based microsegmentation by its cloud-delivered coverage administration platform, working with current community infrastructure with out requiring new {hardware}, brokers, VLANs, or complicated ACLs. The seamless integration enhances the Elisity IdentityGraph™, a complete machine, person, workload id, and attribute database.
Leveraging detailed asset data (together with threat rating, boundaries, machine sort, producer, mannequin, OS, firmware model, and community section), Elisity allows exact, context-aware safety insurance policies throughout the community.
Weismann explains the sensible advantages: “We now have the power to use insurance policies to all customers, workloads and gadgets after they seem on networks, and we are able to apply all insurance policies with confidence that we’ll not disrupt methods or customers.”
Dynamic Coverage Automation and Enforcement
The joint answer permits safety groups to quickly implement least privilege entry by pre-built coverage templates or extremely granular, dynamic microsegmentation insurance policies that mechanically adapt based mostly on machine threat ranges.
In keeping with Weismann, “Utilizing our current mix of Cisco and Juniper switches as coverage enforcement factors is sensible—we all know our community will stay HA, excessive efficiency and we do not have to disrupt our current community structure or add choke factors.”
The Elisity Dynamic Coverage Engine allows safety groups to:
- Create, simulate, and implement insurance policies that forestall lateral motion
- Dynamically replace insurance policies based mostly on real-time intelligence
- Apply least-privilege entry throughout customers, workloads, and gadgets with out operational disruption
- Robotically adapt to altering threat ranges
Major Line Well being: A Success Story
Major Line Well being’s implementation of the built-in answer demonstrates the transformative potential of this integration. The healthcare system lately earned each the CIO 100 Award for 2025 and the CSO 50 Award in 2024 for his or her progressive cybersecurity implementation.
“The synergy between Armis and Elisity has fortified defenses towards focused cyber threats, enhancing total operational effectivity with added layers of safety and visibility,” says Aaron Weismann. “Microsegmentation is a key technique for accelerating our Zero Belief program.”
Major Line Well being deployed the answer throughout their complete enterprise—from outpatient amenities to acute care hospitals. What impressed them most was the pace of implementation: “We had been capable of deploy Elisity at certainly one of our websites inside hours, and by the subsequent day, we had been creating and implementing blocking guidelines. The pace to execution was unbelievable.”
The mixing created a strong safety framework that enabled Major Line Well being to:
- Uncover and visualize each person, workload, and machine throughout their networks
- Acquire complete visibility into over 100,000 IoT, OT, and IoMT gadgets
- Allow dynamic safety insurance policies that adapt to altering vulnerabilities
- Ship frictionless implementation that accelerated their safety roadmap
- Meet compliance necessities together with HIPAA and HiTrust
One revealing perception from their implementation was that their non-traditional computing surroundings (biomedical gadgets, IoMT, IoT, OT) vastly outnumbered their conventional IT property. This bolstered the significance of a safety method that would deal with the distinctive challenges of those specialised gadgets.
