Protecting IoT’s Big Business Opportunities

IoT can open up big business opportunities, but it can also introduce significant security risks as the increasing number of endpoints in the world create new openings for cyberattacks.

This has created a need for specialized security solutions that can address the unique challenges created by IoT deployments, whether they involve connecting new devices or old, industrial assets. Such solutions from existing and emerging vendors range from digital certificates and on-device security agents to device visibility and segmentation software.
