To be current I would expect any security appliance to support the CNSA Suite.
Fortunately, I no longer have to keep current with this stuff, and I would suggest that before doing anything that time be spent discussing developments and forthcoming requirements with an appropriately engaged practitioner. The term appropriately is used advisedly.
As I have previously indicated, going off-piste with respect to encryption and security issues is mostly likely to be regarded as a CLM, regardless.
Well the transition algorithms are clearly, set out. And, you don't have to be a 🤠😎🤓👀🦅 to know that the CNSA compliant algorithms are in use at most of the TLA organisations along with the "Swiftier" businesses, even in NZ (not living in Wellington, this might have blown past Aucklanders 😁 ). There is usually some stuffing around required to access the advisory memoranda.
These algorithms are not used for the more seriously restricted material. But they are adequate for internal banking purposes.
