Every company big and small partners with external vendors for services. Examples can range from architects, caterers, painters, and law firms to content distribution, hosting, marketing insights, email, machine learning, and contingent labor. The exodus of information to these vendors and the need for their integration with internal resources can pose unique security challenges. In the age of daily breaches, how can you verify and improve the security of your vendors? This panel will seek to explore diverse experiences and opinions on vendor security from companies both large and small. Topics of discussion will include varied methods for performing vendor security, approaches to influencing vendors, the value of investment in vendor security versus other security functions and priorities, scaling a vendor security program, and the ultimate question: can you really predict the security maturity and likelihood of a breach in another company?
