Independent security audits are the gold standard for VPN trust verification. NordVPN maintains one of the most comprehensive audit programs in the industry. Here’s what these assessments examine and what the findings mean for users.

No-Logs Assurance: Deloitte Engagements

NordVPN has undergone five no-logs assurance engagements, with the most recent conducted by Deloitte in early 2025. These audits verify that:

• Server configurations match stated no-logs policies
• No user activity data is retained
• Technical infrastructure supports privacy claims

Key finding: NordVPN’s RAM-only server architecture inherently supports no-logs claims, as data cannot persist after server reboot.

Security Testing: Cure53 Assessments

Cure53, a respected German security firm, has conducted multiple assessments of NordVPN’s infrastructure. The December 2025 assessment covered:

Server/Infrastructure Assessment (NOR-28)

• Completed October 2025
• Requested by UAB 360 IT (Nord Security Group entity)
• Positive remarks on overall hardening

Application Stack Assessment (NOR-22)

• Conducted May-June 2025
• Multi-work-package scope including Meshnet and Threat Protection Pro
• Result: No critical vulnerabilities found

Transparency Reporting

NordVPN publishes quarterly transparency reports through their Trust Center, documenting:

• Government data requests received
• How requests were handled
• Commitment to user privacy

This replaced their previous warrant canary approach with more detailed disclosure.

What Audits Mean for You

Independent verification matters because:

1. Claims are tested – Marketing statements are verified by third parties
2. Vulnerabilities are found – Even good products have issues; audits find them before attackers do
3. Accountability exists – Published reports create public record

When choosing a VPN, look for providers with regular, published third-party audits from reputable firms.
