Since very early after its inception, the OISTE Foundation became a partner of the World Trade Points Federation (WTPF), sharing the aim of promoting secure solutions to e-commerce. This collaboration has extended to the UNCTAD (United Nations Conference on Trade and Development) and is centred upon the fight against illicit trade.

The OISTE Foundation is a partner of the Oslo based Business For Peace Foundation and supports its annual meeting, sponsoring a panel on relevant contemporary issues such as the fight against illicit trade and the challenges posed by artificial intelligence.

The OISTE Foundation works with the Humanity 2.0 Forum, a Catholic faith-based organisation working to identify impediments to human flourishing and work collaboratively across sectors to remove them by sourcing and scaling bold and innovative solutions. The OISTE Foundation is a partner of the Zermatt Summit, where it participates actively. In 2019 the foundation sponsored the signature of the Anti-Illicit Trade Declaration.
