About us
QWANT is an European search engine that values you as a user, not as a product.

Overview
Qwant values the contribution of security researchers and invites them to participate in our Bug Bounty Program. This program aims to encourage responsible reporting of potential security vulnerabilities in our systems. By participating, researchers agree to adhere to these guidelines, which are designed to protect both Qwant and the researchers.

Qwant reserves the right to modify, suspend, or terminate the Bug Bounty Program at any time. Decisions regarding reward eligibility and amounts are at Qwant's sole discretion.

Qwant appreciates the efforts of the security community and looks forward to collaborating to enhance the security of our platform. We encourage researchers to approach this opportunity with responsibility and professionalism.

Rewards

Qwant will offer a minimum reward of 100€. There is no maximum reward as it will be determined by Qwant security team according to the level of criticity and impact of the reported vulnerability.

Any non-security related issue (bug, wrong interface/API behavior, ...) will not be eligible for a money reward and should be sent to https://about.qwant.com/en/contact/.

Guidelines and policy

• Non-Disruption: Participants must avoid any action that would disrupt services or compromise any Personally Identifiable Information (PII) data.
• Responsible disclosure: Participants are required to privately report vulnerabilities directly to Qwant though YesWeHack platform and refrain from public disclosure until the issue is resolved. Only the first reporter of a unique vulnerability will be considered for a reward, otherwise the issue will be triaged as Duplicate.
• Participants eligibility: Current or former employees of Qwant are not eligible to participate in this program.
• Prohibited techniques: The use of brute force methods, scanners, or any attempts to perform a Denial of Service (DoS) attack on our platform are strictly prohibited.
• Legal compliance: All activities must comply with applicable local, state, national, and international laws.
• Scope adherence: Participants must stay within the defined scope of the program.
• Physical security and social-engineering: Social-engineering or physical attacks against Qwant employees, offices, contractors, vendors, service providers or data centers are stricly prohibited.
• Code of conduct: Participants are encouraged to approach this program with a constructive and professional attitude.
• Acceptance of terms: Participation in this program constitutes acceptance of these guidelines.
• Violation of terms: Failure to adhere to these guidelines may result in exclusion from the program and potential legal consequences at Qwant's sole discretion
