By now you have probably heard of a major security flaw called Heartbleed which has impacted many e-commerce sites. The good news is that wearvaughan.com is powered by a company called Shopify who was able to fix the security breech within hours of the announcement. Shopify's response was faster than even Google and Yahoo's and as a result there have not been any detected breeches throughout the entire network. For more details, read our security page.
It's definitely safe to shop on www.wearvaughan.com, but we can't speak for any other retailers. If you're not sure, check out this page.
