Effectiveness regarding responsible disclosure and bug bounty services. Very friendly and supportive 3rd party colleagues!

Intigriti is a crowdsourced bug bounty program. Meaning the security of your company is being reviewed by a large community of cybersecurity professionals. I've used Intigriti both as researcher and as business process owner myself. The strong points is that Intigriti really focusses on "community", they interact a lot with the community to keep them engaged and challenged to continue finding security flaws (E.g. by publishing security challenges on social media). Community-building is also done over Slack and Discord. As business process owner of Intigriti I've seen a lot of quality reports coming in which wouldn't have been found by traditional cybersecurity solutions (technologies or regular pentesting).
