Unlikely. Security isn't really a competitive feature for a customer product (security theater, on the other hand…). Ever if an average user had ever cared about security, they would never be able to evaluate the claims until it's too late to matter. And as JBiserkov points out in a sibling comment, GPUs really prioritize power above everything else, it's not like either OpenAI or a gamer would be happy about reducing their TFLOPs/FPS for the sake of security.

Maybe, but GPUs are also used in virtualized environments (datacenters), where you can't ignore these security issues.

The 'S' in FPS stands for "security".

And where is the competition?

Famously Poor Security? :)
