Safari Safe Browsing red screen on internal corporate resource domain

I work for an IT company, and recently we encountered an issue regarding some of our internal domains being flagged as malicious by the Safari's Safe Browsing feature. These domains are used exclusively within our private network for internal purposes such as analytics and CRM. This has resulted in disruptions to our workflow, as our employees using Mac devices are unable to access our company’s essential internal tools. We have submitted false positive reports, but did not get any response. What can I do to promptly resolve this issue?
