Once you have earned an assessment or a certification badge from OffSec, you can highlight that achievement on your social profiles or websites to boost your personal brand.
You may visit achievement badges FAQ to see how to download your badges.
For organizations that have employees with OffSec certifications, they may post the achieved certifications inline with the employees bio/headshot. But, a company is not permitted to use OffSec brand assets/IT such that someone might believe the organization has some affiliation with or an endorsement by OffSec that does not exist.
OffSec Partners are able to highlight their affiliation with OffSec based on their partner agreement. If companies want to become OffSec partners they may apply here.
