How Sealed Surveys keeps your data secure

You value your data privacy and security, even on the cloud. We make that possible with our online survey tool: Sealed Surveys.

Encrypt at the source

When you use Sealed Surveys, your questions and collected responses are encrypted using a key escrow model.

‍

Checkbox holds a wrapped version of your encryption key – but we can't unwrap or use it without your explicit authorization.

The insider access problem

At any SaaS company, support engineers, database administrators, and infrastructure teams have some access to production data.

‍

This access is usually used responsibly, but the exposure is real.

‍

A support ticket might involve a support engineer reading individual responses to sensitive questions – data the survey creator doesn’t want anyone outside their team to see. Sealed Surveys prevents this.

Keep a clear audit trail

Every access event is logged: when it was granted, what was accessed, what actions were taken, and when it was revoked.

‍

You have full visibility over who has been in your online survey tool and who has seen your data and when.

What data is encrypted by Sealed Surveys?

Sealed Surveys focuses on the data that matters most to you and your respondents: the content of your surveys and the answers you receive.

Survey questions and structure

Your survey questions and survey design are encrypted, protecting the intellectual property of your research.

Survey responses

Every response submitted by survey participants – data they trust you to protect – is encrypted end-to-end.

File uploads and attachments

Images used in questions, respondent file uploads, and signature images are all encrypted.

Built for teams where survey data is sensitive data

Some organizations can't afford to presume data protection is in place. Sealed Surveys was designed for the industries where the stakes are highest.

Healthcare, patient, and academic research

Collect HIPAA-sensitive patient feedback on cloud infrastructure without exposing PHI to a third party – including us.

Government and public sector

Meet data sovereignty requirements without maintaining on-premises infrastructure. Sealed Surveys keeps citizen data out of vendor reach.

Market research and consultancies

Your survey IP – the questions, the methodology, the data, the panel – is your product. Sealed Surveys ensures no platform vendor can see it.

Financial and legal services

Run internal compliance surveys, data collection processes, whistleblower channels, and client feedback without creating vendor data-access risk.

Why Checkbox prioritizes data security and sovereignty

Sealed Surveys is part of a broader commitment to giving research teams genuine control over their data.
Checkbox is unique in offering cloud-based encryption or on-premises deployment.

Protect your data from every angle

Beyond Sealed Surveys, Checkbox offers robust data security at the infrastructure level.

‍

Even in the event of a breach, encrypted survey data is unreadable without the encryption keys, so a compromised database doesn't mean exposed responses.

Choose where your data lives

For teams that need full data sovereignty and residency control, Checkbox also offers on-premises and local server deployment options.

‍

Your data stays within your own infrastructure, in the jurisdictions you need it, subject to your IT and governance policies.

Why encryption matters for survey data

Your survey data should only be accessible by the people in your business who need to see it – not by your survey software provider, let alone any other organization. Sealed Surveys prevents the following possibilities.

The insider access problem

At any SaaS company, support engineers, database administrators, and infrastructure teams have some access to production data.

‍

This access is usually used responsibly, but the exposure is real.

‍

A support ticket might involve a support engineer reading individual responses to sensitive questions – data the survey creator doesn’t want anyone outside their team to see. Sealed Surveys prevents this.

The government compulsion problem

SaaS providers can be legally compelled to hand over customer data -- and in many jurisdictions, they may be prohibited from telling you it happened.

‍

The US CLOUD Act allows US authorities to request data stored anywhere in the world, regardless of where your organization or respondents are located.

‍

With Sealed Surveys, Checkbox can't meaningfully comply with such a request, because it can't decrypt the data. That protection is built into the architecture.

What to look for in secure survey software

Not all secure survey platforms are built equal. When evaluating your options, here's what genuinely matters:

Provider-blind encryption – The platform can't access your data by default, even with full infrastructure access.
Customer-controlled access -– You decide if and when the vendor can view your data, scoped to specific surveys or responses and limited by time.
Auditable access logs – Every instance of data access is logged and visible to you, so you're never in the dark about who has seen what.
On-premises deployment option – For teams with strict governance requirements, the ability to host on your own infrastructure is essential.
Encryption at rest and in transit – Collected data should be protected when stored and when it's moving across networks.
Data residency controls – Choose where your data is stored and ensure it stays in the right jurisdictions.

Flexible deployment – Whether you need cloud or on-premises, the platform should accommodate your needs without compromising on functionality.
