Justin Zeefe, a former intelligence officer who is now the president of Nisos, a security firm in Virginia, said his company has worked for tech companies on a wide range of cases. On one occasion, they learned that a company’s overseas suppliers had ties to foreign intelligence agencies.
Another client asked his firm to determine whether an acquisition target had been infiltrated by foreign hackers. Yet another hired Nisos to determine the source of multiple cyberattacks. It turned out to be the work of a competitor that had intercepted the company’s Wi-Fi from an apartment rented across the street.
