Hopefully not hardware with known vulnerabilities.
A lot of IoT devices, cameras, alarm systems, car components have known vulns and are still sold...
It might make sense for a product that is hard to patch due to a more complex manufacture to drain supplies before updating. For a security product that is known to be vulnerable it is not forgivable to keep shipping.
I’d say security cameras and alarm systems are security products, too.
Almost every hardware have known vulnerabilities, you can't just take things off shelves once one is found, they don't have a money printer.
