Abstract: 

Many organizations use phishing simulation campaigns to raise and measure their employees' security awareness. They can create their own campaigns, or buy phishing-as-a-service from commercial providers; however, the evaluations of the effectiveness in reducing the vulnerability to such attacks have produced mixed results. Recently, researchers have pointed out "hidden costs" - such as reduced productivity and employee trust. What has not been investigated is the cost involved in preparing an organization for a simulated phishing campaign. We present the first case study of an organization going through the process of selecting and purchasing a phishing simulation. We document and analyze the effort of different stakeholders involved, and present reflection from semi-structured interviews with 6 key actors at the end of the procurement process. Our data analysis shows that procuring such simulations can require significant effort from different stakeholders - in our case, at least 50,000€ in person hours - and many hidden intangible costs. Evaluating if a product or service meets training requirements, is acceptable to employees, and preparing the technical infrastructure and operational processes for running such a product all require significant time and effort. The prevailing perception that phishing simulation campaigns are a quick and low-cost solution to providing security training to employees thus needs to be challenged.
