有的，官网 https://www.wad.net/
这个组织其实就相当于一个职业联盟，主要是为会员提供更强大的人脉和信息网络以及各种其他支持（指年年开会），同时为委托人提供联系值得信任的专业人士的渠道
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.”
因为在国外这是一个挺大的合法市场，人家是正儿八经做生意的。专业领域也五花八门，从网络安全到背景调查到安保顾问到找猫找狗等等等等都可以算进这一行业。你在官网find an investigator页面也能看到可选择的业务多种多样，顺便我还看到了另外一个应该是更偏重业务联络功能的组织 https://directory.einvestigator.com/ ，有需求的可以上去雇人，干这行的也可以考虑入个会 |
