Unfortunately, StrongVPN doesn’t provide any free trial or limited free version to test its service. Instead, it offers a money-back guarantee available for 30 days, which people can use for a risk-free trial of the full program. While this does mean that a purchase must be made first, the company will issue a refund to anyone who does not want to continue using the service by the end of this month-long period.
The only way to test StrongVPN without any compromises is to make use of the money-back guarantee. All subscriptions to either of the two plans include a 30-day refund period during which the whole program can be used risk-free.
