BitDefender rolled out a bad update yesterday (10/6/2022) which resulted in many having internet connectivity issues. The bad update has been resolved with a new update, product version 7.7.1.216. A network protection policy can be changed as a workaround for those not getting the update. The workaround is to simply turn off SSL scanning (see below).

BitDefender is a widely used endpoint protection platform and EDR tool. Many managed services providers and direct customers noticed the impact and BitDefender has been working to quickly resolve the issue. It does not appear that a public statement on this has been reported and BitDefender is only reaching out to customers directly relating to the issue.
