At Nord Security, we strive to maximize the security of our infrastructure and customers' data. We believe that in order to reach our goal community participation is essential. Please note that your submission of potential security vulnerability finding (“Vulnerability Finding”) is voluntary and subject to the terms and conditions set forth in this Policy. By submitting a vulnerability to us you acknowledge that you have read and agreed to this Policy.

Program Rules

Our main rules are as follows:

• Automated testing is not permitted.

• Follow HackerOne’s Disclosure Guidelines.

• You must be the first person to notify us of a finding that alerts us to a previously unknown issue and that issue triggers a code or configuration change. If different attack vectors result in the same mitigation, Nord Security reserves the right to reward only the first report that is validated for that fix. All subsequent reports that are addressed by that mitigation will be considered as duplicates, regardless of the attack vector. In most instances, you will not be notified of a duplicate report condition until after the vulnerability has been fully remediated.

• We award bounties once the vulnerability is fixed, and will keep you posted as we work to resolve them.

• We reserve the sole right to determine the size of the reward if any. We determine this on a case-by-case basis, depending on overall severity (including the business impact, creativity of the issue, etc.). You shall respect our final decision.

• We may pay even higher rewards for, especially clever or severe vulnerabilities. We recommend for you to use Common Vulnerability Scoring System Version 3.0 Calculator as a general guide on vulnerability severity levels. However, please note that this serves only as a rough guide and does NOT guarantee that we will give the same evaluation to your Vulnerability Finding. The final and actual severity level is determined by us in our sole discretion.

• To receive a reward, you must disclose the vulnerability report directly and exclusively to us.

• Previous reward amounts are not considered a precedent for future reward amounts.

• Reward may be denied if there is reason to believe that there has been a violation of this Policy.

• You may need to provide additional information, which would be necessary to receive the reward.

• Taxes on rewards given to you are your sole responsibility.

• Reward will be forfeited, if it remains unclaimed or undeliverable for a period of six (6) months counting from the date you are notified of the determined reward amount

• Contacting our team regarding the status of a report through any other channel than Hackerone will result in an immediate disqualification for a bounty for that report.

• Please recognize that Nord Security operates complex infrastructure and the amount of time required to address a reported issue can vary from a few hours to several months. You will receive notification of the final outcome of our remediation efforts once the report has been passed to the internal security team. Nord Security cannot provide updates on remediation efforts that are in progress.

This Policy supplements the terms of any other agreement (collectively – “Agreements”) in which you have entered with us. If any inconsistency exists between the terms of the Agreements and this Policy, this Policy will prevail, but only with regard to the potential security vulnerability reporting, unless otherwise agreed by us in writing.
