The way most enterprises evaluate hardware security hasn’t kept pace with the threats they face. Certifications, encryption checkboxes, and compliance frameworks remain the dominant currency of procurement conversations – but they answer a different question to the one that actually matters.
Stella Cheng, Product Security Manager at Yealink, puts it plainly. “A certification can demonstrate that a particular management system or control environment meets defined requirements. Encryption can protect data in transit or at rest. Regulatory compliance can establish important obligations around data and privacy.”
“But none of these, individually, answers the larger question: can the vendor be trusted to manage security throughout the product lifecycle?”
The Case Against the Checklist
Enterprise security procurement has historically revolved around a familiar set of questions.
Does the device have encryption? Does the vendor hold ISO certification? Is it GDPR-compliant? These are reasonable questions – but Cheng argues they are incomplete ones.
The company structures its security commitments around the S.A.F.E.R. ("Standards & Compliance Foundation, Accountability, Future-proof Security, Ethics, and Reliability) framework – five pillars that span Supply Chain Security, Authentication and Identity, Future-proof Security, Ecosystem Trust, and Regulation and Compliance.
The framework is not intended as a marketing taxonomy.
It is an attempt to articulate what security actually means across the full arc of a product’s life – from first design decision to the moment a device is eventually decommissioned.
Security Starts Before the First Line of Code
The most consequential security decisions, Cheng suggests, are often made before engineering begins. “During product planning and architecture, we consider questions such as: What assets need to be protected? What are the trust boundaries? What are the relevant attack surfaces? How should identities and credentials be protected? What happens if firmware is compromised?”
This is the distinction Yealink draws between security as a testing activity and security as an engineering discipline.
Testing can identify weaknesses in a finished implementation. A Secure by Design approach asks a harder question earlier: how do we design the product so that potential weaknesses are less likely to occur in the first place?
The difference matters in practice. Decisions about Secure Boot, firmware integrity, device identity, and authentication are most effective when made at the architecture stage – not retrofitted before launch.
Yealink operates a Secure Development Lifecycle to embed these considerations into normal product engineering rather than treating security as a separate, parallel process.
Following the Device
One way to understand how security plays out in practice is to follow a Yealink device through its lifecycle.
At the planning and architecture stage, security requirements sit alongside functional ones.
At the development stage, the picture broadens: a modern collaboration device is built on chipsets, operating systems, third-party libraries, and firmware from multiple suppliers.
