Cloud and on-premise eQMS platforms can both be fully compliant with FDA, MHRA, EU MDR and ISO 13485, and both can satisfy regulators. What is actually assessed is data integrity, access control, audit trails, and validation evidence, not where the system is hosted.
For growing medical device manufacturers without a large in-house IT function, cloud generally gets you to a validated, audit-ready position with less overhead, which is the approach Cognidox is built around.
For medical device manufacturers, choosing between cloud and on-premise is one of the more debated parts of an eQMS decision, and it's often assumed to be a compliance question. It isn't, at least not directly.
ISO 13485:2016, EU MDR, and FDA requirements focus on whether your design history file, technical documentation, and quality records are accurate, attributable, and retrievable, and whether the system that manages them has been validated. The FDA’s Quality Management System Regulation (QMSR), in force since 2 February 2026, incorporates ISO 13485:2016 by reference.
This article sets out what that means in practice, and where the two hosting models genuinely differ.
Neither the FDA, MHRA, EU MDR, nor ISO 13485 specifies where an eQMS must be hosted. For medical device manufacturers, this includes Notified Body assessments under the EU Medical Device Regulation (MDR) and In Vitro Diagnostic Regulation (IVDR), which review your quality management system and technical documentation against the regulation, not the infrastructure on which it runs.
These frameworks specify the behaviour the system must exhibit: data integrity, controlled access, a complete audit trail, and evidence that the system has been validated for its intended use.
This requirement is usually summarised using the acronym ALCOA+, an extension of the ALCOA principles referenced in FDA data integrity guidance and set out in MHRA, EMA and PIC/S guidance to describe what trustworthy regulated data looks like. Data should be: Attributable, Legible, Contemporaneous, Original and Accurate, and also Complete, Consistent, Enduring and Available.
Nothing in ALCOA+ mentions server location. A cloud system that meets all nine principles is just as compliant as an on-premise one that does the same, and vice versa.
An auditor assessing your eQMS is working through a fairly consistent checklist, and it applies identically whether your records live in your own server room or in a vendor's data centre.
Every change to a controlled document or record needs a time-stamped, attributable entry that can’t be edited or removed. FDA 21 CFR Part 11 requires secure, computer-generated, time-stamped audit trails that independently record the date and time of operator entries and actions creating, modifying or deleting electronic records, and requires that audit trail documentation be retained at least as long as the records it relates to.
The system must restrict who can view, edit or approve records, with unique logins rather than shared credentials. Shared login credentials are a recurring data integrity finding in FDA warning letters, and they're just as much a risk on an on-premise server as in the cloud.
Auditors want evidence that records would survive a system failure, and that recovery has actually been tested, not just documented as a policy.
The system managing your records must be validated for its intended use. In ISO 13485:2016, that requirement sits in clause 4.1.6, which covers software used in the quality management system. Validation has traditionally been evidenced through a package covering installation, operational and performance qualification (IQ/OQ/PQ). In the US, FDA’s final Computer Software Assurance guidance (September 2025) now encourages a risk-based approach that scales the depth of testing to the risk the software poses.
If your eQMS can produce clear evidence against each of these four points, the hosting question becomes secondary. If it can't, moving it on-premise won't fix that.
Not inherently. A cloud eQMS can meet or exceed on-premise security, provided the vendor can evidence equivalent controls: encryption in transit and at rest, logged access, and independent certification such as ISO/IEC 27001:2022 or a SOC 2 report.
The assumption that on-premise is automatically safer usually comes from familiarity rather than evidence. An on-premise server gives you physical control, but physical control isn't the same as security. A self-hosted system is only as secure as the patching schedule, backup regime and access policy your own IT team maintains, and smaller organisations may lack the resources to do this as rigorously as a specialist vendor does at scale.
This is usually the real question behind the security concern, and it has a concrete answer. A properly run cloud eQMS vendor will tell you exactly which data centres your records are held in, often within the UK or EU, which simplifies compliance with UK GDPR and EU GDPR rules on international data transfers, and will set this out in a data processing agreement.
Cloud-hosted records are typically easier for inspectors to review than on-premise ones, not harder. A cloud eQMS can usually provide inspectors with controlled read-only access or export a defined evidence package covering the records and audit trails under review, without requiring an inspector to enter a server room or copy data to physical media. On-premise systems can achieve the same outcome, but it depends entirely on how well the organisation has prepared for it in advance.
Once compliance is taken off the table as a differentiator, the decision comes down to genuine operational trade-offs.

For organisations with a large, established IT and validation function, keeping systems on-premise can make sense, particularly where there's already sunk investment in infrastructure.
For organisations without that capacity, and this describes most growing regulated businesses, a cloud eQMS shifts a significant amount of validation and security work onto a vendor whose core job is to do it well.
The decision comes down to four practical questions, not a compliance test.
For a scaling medical device manufacturer working towards ISO 13485 certification and CE or UKCA marking, often without a dedicated IT function, a cloud eQMS generally gets you to a validated, audit-ready position faster, and supports the kind of distributed, remote working that's now routine across device development teams.
That's the balance Cognidox is built around: the governance and traceability your assessors and regulators expect, delivered through a cloud platform that doesn't require an enterprise IT team to run it.
Cloud and on-premise eQMS platforms can both be fully compliant. What is actually assessed is data integrity, access control, audit trails, and validation evidence, not server location.
The genuine differences between cloud and on-premise are cost, IT burden and scalability, not compliance.
If you're weighing up how a cloud eQMS would hold up under FDA or MHRA scrutiny, our compliance page outlines how Cognidox is built to meet Part 11 requirements as standard. Or book a demo to see it in practice.
No, the FDA doesn’t require on-premise hosting for regulated data. FDA 21 CFR Part 11 sets requirements for electronic records and signatures, such as audit trails and access control, but it doesn't specify where the system must be hosted. Cloud-hosted records can meet Part 11 requirements in full.
Yes, a cloud eQMS can support compliance with 21 CFR Part 11, provided the system delivers the required controls. These include attributable, time-stamped audit trails, unique user access, secure electronic signatures and validated operation. Compliance depends on these controls being demonstrable, not on the hosting model.
Yes. Most cloud eQMS platforms, including Cognidox, can provide inspectors with controlled read access or export a defined evidence package covering the records under review, often more straightforwardly than arranging physical access to an on-premise server.
