Both deployment models can be made HIPAA-compliant and both have been breached. The security difference between them is not that one is inherently safer. It is where the security responsibility sits and which specific threats each model is better or worse at defending against.
Ekim IT Solutions is the dental-exclusive IT provider that manages both cloud-based and on-premise dental practice management systems for practices across Maine, New England, Tampa Bay, and nationally, which puts us in a position to give an honest security comparison that neither cloud vendors nor server vendors volunteer.
Cloud dental software vendors frequently imply their platform is more secure than on-premise because they manage the server infrastructure. What they do not emphasize is that the practice remains fully responsible for workstation security, access controls, and staff behavior, which is where most dental practice breaches actually originate.
Cloud-based platforms have genuine security advantages in these areas.
Cloud dental platforms like Denticon, CareStack, and Curve Dental run on enterprise-grade data centers with physical security, redundant power, and professional security operations.
Most dental practices cannot match this with on-premise server rooms.
Cloud platforms apply security updates to the platform infrastructure automatically.
An on-premise platform requires the practice’s IT provider to apply updates on a schedule, and delayed patching is one of the most common ransomware entry points in dental practices.
A cloud platform has no on-premise server that can be stolen, physically accessed, or damaged by fire, flood, or hurricane.
That physical attack surface simply does not exist.
On-premise platforms give the practice direct control over the physical location of patient data. For practices with specific compliance requirements around data residency, or those concerned about cloud vendor data access during legal proceedings or security incidents, an on-premise database with properly configured encryption and access controls keeps patient data under the practice’s direct management.
On-premise platforms also have no internet dependency for basic functionality. A practice running Dentrix or Eaglesoft locally can continue scheduling and charting during an internet outage. A cloud platform is completely offline under the same circumstances.
The most common dental practice breach vectors, phishing attacks on staff credentials and ransomware delivered through email, affect both deployment models equally. A staff member whose email credentials are compromised gives an attacker the same access whether the practice runs Dentrix on a local server or Curve Dental in the cloud. Endpoint security, MFA, and staff training are the controls that matter most for these attack vectors, and they apply identically to both deployment models.
HIPAA does not prefer cloud or on-premise deployment. Both require a BAA with the software vendor, both require encryption of ePHI at rest and in transit, and both require the same access controls and audit logging. The Security Risk Assessment for a cloud practice must document the cloud vendor’s security practices and BAA. The Security Risk Assessment for an on-premise practice must document server security, encryption configuration, and physical access controls. Ekim IT Solutions builds the appropriate documentation for both deployment models.
These controls matter identically whether your practice runs cloud-based or on-premise software. Check each item confirmed.
Endpoint security is deployed and active on every workstation
MFA is enforced on all remote and cloud access
Staff phishing awareness training is conducted regularly
A signed BAA is in place with the software vendor
Encryption of ePHI at rest and in transit is confirmed
A Security Risk Assessment is completed and documented for your specific deployment model

We are not selling you a deployment model. We are telling you where the responsibility sits and which threats your specific setup is exposed to.
