有的，官網 https://www.wad.net/
這個組織其實就相當于一個職業聯盟，主要是為會員提供更強大的人脈和信息網絡以及各種其他支持（指年年開會），同時為委托人提供聯系值得信任的專業人士的渠道
引用 In the words of our Past President Richard Jacques-Turner, “W.A.D. remains the foremost International Association of Professional Investigators and Security Service organizations. We have the history and strength to give the best service to our members. The inexorable march of data protection legislation has created a minefield that lies in wait for even the most experienced investigator, particularly those engaged in international work. If you are involved in international investigations then you need W.A.D. to help you. W.A.D. also needs your help in order to strengthen our profession. A larger membership means a stronger voice when dealing with legislators and more money to fight restrictive legislation.”
因為在國外這是一個挺大的合法市場，人家是正兒八經做生意的。專業領域也五花八門，從網絡安全到背景調查到安保顧問到找貓找狗等等等等都可以算進這一行業。你在官網find an investigator頁面也能看到可選擇的業務多種多樣，順便我還看到了另外一個應該是更偏重業務聯絡功能的組織 https://directory.einvestigator.com/ ，有需求的可以上去雇人，干這行的也可以考慮入個會 |
