Cloud PCB Design: 5 Cloud Security Myths Debunked

Moving electronic product development workflows to the cloud raises understandable security concerns. Your designs and the associated data represent valuable intellectual property, and many electronics design teams operate under strict security and compliance standards. You’re right to wonder if a cloud collaboration platform offers the best possible security.

But, the reality is that modern cloud platforms often provide better security than traditional on-premises solutions. Major cloud providers invest in security and compliance expertise that most companies can’t hope to match. Cloud security breaches are rare, and when they occur, they are almost always the result of user error.

Nevertheless, a handful of persistent cloud security myths prevent some organizations from adopting a cost-effective, secure, cloud-based collaboration solution like Altium Agile. In this article, we'll examine six cloud security myths and how modern cloud solutions address security challenges, from encryption and access control to compliance and auditing.

Debunking Cloud PCB Design Security Myths

Despite the proven security record of cloud platforms, misconceptions persist about their safety and suitability for sensitive data storage and sharing. These myths often stem from outdated information or misunderstandings about how modern cloud security works.

1. Cloud Storage Is Inherently Less Secure Than On-Premises Servers

Our first cloud security myth stems from a natural instinct: keeping sensitive electronics design data on your own servers, behind your own firewall, feels more secure than storing it in the cloud. The thinking goes that if you can't manage the servers, you can't truly control the security. Consequently, some electronics design companies rely on local file storage and manual file sharing methods, believing it gives them better control over their intellectual property.

However, the reality is that cloud storage often provides better security than on-premises alternatives, especially when it comes to secure data sharing and collaboration.

Modern cloud collaboration solutions build on infrastructure managed by major cloud platforms—AWS in Altium’s case. These platforms invest heavily in security infrastructure and expertise that would be prohibitively expensive for most organizations to maintain internally. They employ teams of security experts, conduct regular security audits, and maintain sophisticated threat detection systems.

Most importantly, the cloud solves one of the biggest security challenges in electronics design: secure collaboration. When teams rely on local storage, they often resort to insecure methods of sharing design files: email attachments, USB drives, or consumer file-sharing services.

Each of these methods creates security vulnerabilities. One of the most common data breach vectors is also the least complex: someone with access to sensitive data accidentally emails it to the wrong person.  Consumer-grade file-sharing services lack the protection needed to keep sensitive data safe. USB drives have been implicated in numerous data leaks.

In contrast, cloud platforms provide secure, controlled methods for sharing designs with team members and external partners. All file access occurs through encrypted connections with comprehensive access controls. Audit logs track every interaction.

Protecting IP in a collaborative cloud PCB design environment comes down to three controls working together: access permissions that restrict who can view or download design files, encrypted storage and transmission so data can't be intercepted in transit, and comprehensive audit logs that create a traceable record of every interaction with the design. With Altium, all three are in place by default.

2. Cloud PCB Design Workflows Can’t Be Configured to Meet Strict Security Requirements

Some organizations believe that cloud platforms offer a one-size-fits-all approach to security that can't accommodate their specific requirements. This myth likely originated with early cloud storage solutions that provided limited security configuration options.

Today's electronics design collaboration platforms offer sophisticated data security and access controls that can be tailored to meet even the strictest security requirements. Organizations can take advantage of granular access controls, including IP whitelisting to restrict access to specific networks, role-based permissions to control what users can view or modify, SSO integration, and workspace isolation to separate projects or teams.

3. We Can't Be Sure Cloud Platforms Comply With ITAR and EAR Requirements

Organizations working with ITAR-controlled or EAR-regulated data often assume that cloud platforms cannot meet their strict compliance requirements. The concern is understandable, given the serious consequences of compliance violations. However, military electronics designers, aerospace and defense electronics designers, and other organizations that must comply with ITAR and EAR can use purpose-built solutions specifically designed to address these regulatory requirements. 

Altium 365 GovCloud operates exclusively within U.S. borders on AWS GovCloud infrastructure. Access to workspaces from outside of the U.S. is controlled through our Web Application Firewall (WAF), which blocks access from non-US-based IP addresses. Projects, libraries, and other data cannot be shared with anyone outside of the workspace without explicit authorization (controlled by the Workspace Owner and/or Administrator). For organizations working under ITAR and/or EAR requirements, purpose-built cloud solutions simplify compliance by providing compliance controls equivalent to or superior to those of traditional on-premises systems while also being significantly more cost-effective.

The key difference between Altium 365 GovCloud and the standard Altium environment is where data resides and who can access it. Standard Altium runs on AWS commercial infrastructure and is accessible globally. GovCloud runs exclusively on AWS GovCloud — a physically separate infrastructure operated by US persons and located entirely within the United States — with access blocked by default to any IP address outside the US. This geographic and infrastructure separation is what enables ITAR and EAR compliance, since those regulations require that controlled technical data not be accessible to foreign nationals.

Compared to an on-premises ECAD setup for ITAR compliance, Altium 365 GovCloud offers several practical advantages: no internal server infrastructure to maintain, built-in access controls and audit logging that satisfy compliance documentation requirements, and automatic enforcement of US-person-only access through the Web Application Firewall (WAF) — rather than relying on physical access controls and manual processes. The compliance burden shifts from your IT team to the platform. On-premises setups can achieve equivalent control, but require significantly more internal resource investment to implement and maintain audit-ready documentation.

To restrict PCB design file access to US persons only, Altium 365 GovCloud handles this at the infrastructure level through the WAF, which automatically blocks non-US IP addresses from accessing the workspace. Within the workspace, the Owner and Administrator control who is granted access, ensuring that only authorized users — verified through your organization's identity management system — can view or download design data.

4. There’s No Way to Track Who Views or Downloads PCB Designs

Modern cloud PCB design platforms offer comprehensive tracking and auditing features that exceed what's possible with siloed on-premises storage. Altium includes comprehensive event logging. Every interaction with a design file—whether viewing, downloading, or modifying—is automatically logged with details, including the user's identity, timestamp, and type of access. These audit logs can be integrated with your existing Security Information and Event Management (SIEM) systems.

Platform administrators can generate detailed reports showing who accessed what files and when, making it easier to maintain security compliance and investigate any suspicious activity. This level of tracking helps organizations maintain better control over their intellectual property than traditional file-sharing methods.

5. Sharing Design Files in the Cloud Makes It Impossible to Enforce Strict User Permissions

A persistent cloud security myth implies that sharing design files means losing control over who can access them. The opposite is true. Enterprise cloud PCB design platforms provide sophisticated permission systems that give organizations precise control over their design data. Administrators can set granular permissions at both the workspace and project level, controlling what each user can view, edit, or share. For external collaboration, Altium users can securely share data with third parties with complete control over access rights.

These permission systems integrate with existing enterprise identity management solutions, ensuring consistent access policies across your organization. Unlike manual file-sharing methods, cloud platforms enforce permissions automatically and maintain detailed logs of all sharing activities, making it easier to maintain security compliance.

To generate an audit trail showing who accessed your electronics design files and when, navigate to the Admin panel in your Altium workspace and open the Events Log. Every file view, download, comment, and modification is recorded there with the user's identity, timestamp, and action type. For GovCloud workspaces, these logs can be exported and integrated into a SIEM system for continuous monitoring and compliance reporting.
