ECN runs its own network behind a written uptime SLA

As a division of JSE-listed Reunert, it suits enterprise and wholesale buyers who value that backing. Pricing is quote-only across an eleven-product catalogue, so get the SLA and service-credit remedies in writing and ask for three reference customers in your industry before committing.
