Case Study: Distributel Communications Limited achieves CRTC SHA-2 compliance and reliable AS2 integration with Cleo

Telecommunications Giant Stays in Compliance with Superior AS2 from Cleo

Distributel Communications Limited, Canada’s leading independent telecommunications services provider, faced a regulatory and technical challenge when the CRTC mandated SHA-2 encryption for AS2 exchanges. Their incumbent AS2 software could not fully support the move to TLS 1.2/AES-256, threatening compliance for critical functions like number porting, billing and hosting 411/711 data. Distributel evaluated Drummond‑certified vendors and selected Cleo, including a rollout of Cleo Integration Cloud, to meet the mandate.

Cleo delivered a Drummond‑certified AS2 solution that supports SHA-2, TLS 1.2 and AES-256, and is easy to use and manage; Distributel has since deployed multiple Cleo solutions to consolidate systems after acquiring Yak. The implementation restored compliance with CRTC requirements, eliminated the frequent crashes and support issues of the prior platform, and produced measurable operational improvements—no reported downtime, reliable exchanges, and markedly improved support from Cleo.
