In 2015, there were approximately 3.5 billion internet of things (IoT) devices in use. Today, the number stands around 35 billion, and is expected to eclipse 75 billion by 2025. IoT devices range from connected blood pressure monitors to industrial temperature sensors, and they're indispensable. The challenge was the driving force behind Ordr, a startup focused on network-level device security. Pandian Gnanaprakasam and Sheausong Yang -- who between them had tenures at Cisco, Aruba Networks, and AT&T Bell Labs -- co-founded Ordr in 2015 to address what they call the "visibility gap" in enterprise networks.

Security company Vailmail released the Summer 2019 Email Fraud Landscape report on Tuesday highlighting recent efforts by enterprises to protect email accounts from cyberthreats. The report mostly focuses on the adoption rate of Domain-based Message Authentication, Reporting and Conformance (DMARC), a system that allows email domain owners to protect their domain from unauthorized use or "spoofing." Vailmail's researchers found that most enterprises were taking a positive step forward and saw a huge spike in DMARC adoption worldwide. Yet despite widespread adoption, the study found more than 90% of enterprise domains remain vulnerable to email impersonation attacks. By using DMARC and other similar authentication systems, domain owners can publish text files in the Domain Name System (DNS) laying out specific policies for how mail receivers should deal with unauthenticated email that appears to come from their domains.
