Private Equity (PE) today faces new challenges in the form of cyber risks to not only the PE firm but the portfolio as well. It is this large attack surface that can make it very difficult to accurately quantify risk. During a Halogen assessment, Vulsec learned valuable methods of detecting and quantifying risk. With the use of Halogen, we analyzed over 140 of this client's portfolio companies. Within 15 minutes of Open Source Intelligence, we learned everything that an attacker would be able to use against these companies by utilizing public information.
