What Internxt Send is
Internxt Send is a web service for transferring files through an encrypted link or email. It supports files up to 5GB per transfer and can be used as often as needed without a subscription, credit card or login. Links remain valid for 15 days. Recipients can open a Send link or email whether or not they have an Internxt account. Internxt says Send uses zero-knowledge encryption, with keys managed on the user’s device, and describes its transfer protection as including post-quantum encryption. The company also says its services are open source and its platform has been audited by a European penetration-testing company. Shared file data is kept away from third parties and is not used to train AI or machine-learning models, according to Internxt. Customer Success support is available through live chat or [email protected]. Internxt was founded in 2020 and is headquartered in Valencia, Spain.
