DigiCert: Scalable, Trusted Security for IoT Systems

Jason Sabin, Chief Security Officer
The exponential growth of devices and objects connected to the web, known as the Internet of Things (IoT), brings with it new business opportunities and lifestyle enhancements, not only for organizations and consumers but also for hackers looking to take advantage of poor security. With large amounts of sensitive data being generated and shared by IoT devices, the need for scalable, trustworthy security has never been greater. One answer comes from a solution that has been working quietly to protect data for a long-time—Public Key Infrastructure (PKI).

DigiCert, the Lehi, Utah-based firm is in the forefront, as the world’s second-largest issuer of high-assurance SSL/TLS certificates for enterprises and emerging markets. As a leader in advancing best practices and innovation for the authentication and encryption markets, DigiCert provides end-to-end security and large-scale certificate management for the IoT.

“DigiCert offers the proven security of PKI at the scale that the IoT ecosystem requires,” says Jason Sabin, Chief Security Officer, DigiCert. “Together with our reputation for excellence and customer focus, we’re seeing many firms approach us for deployments of large quantities of digital certificates to secure their IoT products.”

The IoT market is booming. According to recent reports, by 2020, an estimated 25 billion devices will be connected to the IoT. As these devices become more integrated into everyday living, innovative security solutions are needed to protect end-users from eavesdropping or malicious attacks.

“If correctly implemented, PKI can support security and trust at the enormous scale that IoT ecosystems and networked devices require,” adds Sabin. “PKI provides strong identity authentication and creates the foundation of trust that systems, devices, applications, and users need to safely interact and exchange sensitive data.”

DigiCert’s IoT solutions work for organizations across a wide spectrum of vertical markets, whether those be manufacturing, healthcare, industrial infrastructure, wearables, automobiles.

DigiCert’s all-in-one Managed PKI, cloud-based platform, named CertCentral™, and simplifies certificate management throughout all phases of the certificate lifecycle. The platform also allows users to request and renew certificates in just a few clicks of a mouse and in matter of a few minutes or lesser to save administrators time.
CertCentral also provides real-time monitoring of all digital certificates issued for an organization’s domains to detect fraud and mis-issuance and help assure compliance across the organization. CertCentral’s inspection functions help organizations identify weak configurations to close potential security gaps, and administrators are able to track spending by allocating each certificate to a specific business unit.

DigiCert’s validation team works round the clock to ensure that customer identities can be thoroughly vetted while issuing certificates faster than any other public CA. Geo locating its data centers around the world helps DigiCert provide the fastest OCSP times, which is the check made by an Internet browser when determining if a digital certificate is legitimate, which improves page load time to keep end-users from abandoning a page.

“DigiCert helps save our customers’ time and manpower, and potentially avoid the devastating consequences of improper configuration of digital certificates,” says DigiCert Vice President of Operations Flavio Martins. “Our expert teams help provide guidance for our customers and simplify IoT certificate management,” adds Martins.

Recently, Plex, one of the leading personal media streaming solutions, collaborated with DigiCert to provide publicly trusted certificates for all Plex media streaming and cloud services. DigiCert’s certificate-based IoT solution allows Plex to provide end-to-end security for tens of millions of Plex media servers and clients, through automated, PKI-based deployments.

“The IoT landscape is quickly advancing, evolving, and more organizations are shifting to DigiCert because we are agile and responsive, and able to innovate with the certificate management solutions that meet their needs,” concludes Sabin. “We’re excited about the future ahead.”
