Ah, yeah I feel you. That’s indeed an uphill climb especially if the higher ups themselves do not support you. I think a cybersecurity event is a good way to do it. If you end up getting smaller funding, you can also do short brownbag meetings with free snacks and/or giveaways. Free stuff is always an incentive for people to attend. Keeping events short (30 minutes or less) also helps. Then make your presentations interactive, instead of just lecturing do’s and dont’s to employees. Do scenario based discussions and let employees come up with ideas/solutions. That reinforces the knowledge if they “come up with the answers” and you validate them.
