What are Censornet customers saying?


“Most importantly, our multi-cloud strategy meant we needed robust cloud security. But there were other issues we wanted to address. In the past, for example, we used traditional web security proxies, but this led to challenges with delivering local content. Reporting and auditing could be problematic too, with previous solutions reporting everything, without filtering out unwanted noise, making it hard for individuals to use.”

“Securely delivering global content was always a challenge. With Censornet’ cloud controls and web security, we’ve been able to quickly and easily deploy a cost-effective, widely accessible and, most importantly, extremely secure way to address this.”
