That&#x27;s actually meaningless without context. Reason is tags are used to fo all kinds of things in tagged CPU&#x27;s. Some have almost no safety while some support arbitrary security policies. So, we have to wait and see for each individual implementation.<p>Far as safe&#x2F;secure, look at crash-safe.org for best in class of those. SAFE architecture isn&#x27;t just tagged: it&#x27;s holistic in addressing security &amp; SW dev issues at each layer. Actually, they might be trying to do too much haha. Told people they should&#x27;ve just ported Oberon or Java to the CPU to give us interim solution.
