Every shop should have SSO, period, as a security requirement.

Not offering SSO outside of extremely expensive "Enterprise Plans" is actually hurting national security by segmenting access / control / auditing.

It sucks. Either vendors need to offer SSO across the board on much lower plans, or the Fed Gov needs to step up and help subsidize costs for the CISA 16 identified critical infrastructure sectors.

Just to add to this, a lot of those businesses in those industries are NOT in "IT", and have awful Operational Technology networks and security, yet their business as a chemical supplier, or shipping company, or finished materials producer, or even a small regional ISP is both "critical" to the country, and yet lucky to even have a handful of staff looking at "IT" or security.

SSO tax is creating a lot of barriers and problems that it doesn't even realize.

Something has to give.
