> How is this supposed to deter them
Unisys and Avaya are both security vendors. This absolutely is a bad look for them, as almost every Security RFP asks about internal controls and how a vendor has remediated against these issues, and this is ammunition for any competitor to ask a prospect to re-evaluate purchases from either due to misrepresenting their security procedures.
Furthermore, Unisys only has an operating profit of around $200M a year, so a $4M fine is fairly brutal (that's an entire security team's operating budget for a company at Unisys' size).
Avaya's is smaller still, so that $1M is fairly brutal for them
