Gymshark is a fitness apparel & accessories brand, manufacturer and online retailer based in the United Kingdom. Gymshark has grown from a screen printing operation in a garage, into one of the fastest growing and most recognisable brands in fitness.
Our vision is to unite the conditioning community, and Gymshark wants to ensure the safety of this community and family whilst using our services.
We work hard to develop secure services, and we recognise the importance that the wider security community has in further enhancing our security posture. This is why we've launched Gymshark's Vulnerability Disclosure Program, and we look forward to working with you!
If you believe you've found a qualifying security vulnerability in an in-scope asset, please submit a report in accordance with the guidelines below that includes a detailed description of your discovery with clear, concise reproducible steps or a working proof-of-concept.
Response Targets
Gymshark will make a best effort to meet the following SLAs for hackers participating in our program:
| Type of Response | SLA in business days |
|---|---|
| First Response | 2 days |
| Time to Triage | 2 days |
| Time to Resolution | dependent on severity and complexity |
We’ll keep you informed about our progress throughout the process.
