$SFOR- It's a big deal Maronti for sure. If I am not mistaken , settlement with Trustwave has a clause / someone shared kay's email in the past, that going forward Trustwave will not use DUO's SFOR infringed MFA/OOBA/'698 IP & if they do, they have to pay SFOR. All Trustwave related damages where plugged into DUO's damages.
They can use SFOR's IP for OOBA/MFA. Just wait when this fly's one day ( & that day is not too far ) from this level altogether & it will happen fast.
