6 terms

iec 62443-4-1 regulatory

"certified by UL Solutions to the IEC 62443‑4‑1 Maturity Level 2 (ML2)"

IEC 62443-4-1 is an international standard that prescribes how manufacturers should design, build, test and maintain secure industrial control and automation products, describing a set of practical steps to prevent and fix software and hardware vulnerabilities. Like a building code for factory control systems, following it reduces the chance of cyberattacks, costly outages, regulatory fines and reputational damage, which can directly affect sales, liabilities and a company’s valuation.

secure development lifecycle technical

"IEC 62443‑4‑1 standard defines the requirements for a secure development lifecycle"

A secure development lifecycle is a disciplined process that builds security checks and fixes into each stage of software or product creation—from initial design through coding, testing, release, and ongoing updates. Like adding fireproofing and inspections while a house is built, it lowers the chance of costly breaches, regulatory fines, and emergency fixes, making a company’s products more reliable and preserving revenue and reputation—information investors use to judge operational risk.

threat modeling technical

"including threat modeling, secure design practices, rigorous implementation controls"

Threat modeling is the process of systematically identifying what could harm a company's digital systems, how those harms might occur, and which weaknesses to fix first. Like creating a home-security plan that maps entry points, valuables and likely intruders, it helps management prioritize protections and spending; for investors, strong threat modeling signals lower risk of costly breaches, downtime, regulatory fines or reputational damage.

firmware technical

"reduces risk across the hardware–firmware stack and supports our customers"

Firmware is the built-in software that tells a physical device how to operate, stored in the device’s permanent memory rather than on a removable app. Think of it as the instruction manual glued into a gadget’s brain that controls basic functions and features. Investors care because firmware updates or flaws can change a product’s capabilities, security, repair costs, regulatory compliance and customer satisfaction, all of which can affect sales, margins and company value.

cyber resilience act (cra) regulatory

"readiness for emerging regulatory requirements such as the EU Cyber Resilience Act (CRA)"

A regulatory framework that sets mandatory cybersecurity requirements for digital products and software sold in the covered market, requiring makers to build security into design, test for vulnerabilities, and report serious flaws. It matters to investors because compliance can affect a company’s costs, legal exposure and ability to sell products, similar to how a car safety inspection influences manufacturer expenses and consumer trust—noncompliance can create financial and reputational risk.

industrial automation and control system technical

"Maturity Level 2 (ML2) Industrial Automation and Control System standard"

A set of machines, sensors, software and controllers that operate and monitor factories, plants or other industrial equipment to carry out tasks automatically rather than by hand. Think of it as the conductor, sheet music and orchestra for a factory: it coordinates steps, keeps processes consistent, and detects problems. Investors care because these systems drive productivity, lower labor and error costs, require capital and maintenance, and carry operational and cybersecurity risks that affect profit and valuation.

Secure Development Processes Advance CRA Readiness and Increase Customer Cybersecurity Assurance

CHANDLER, Ariz., April 02, 2026 (GLOBE NEWSWIRE) -- As connected systems spread across residential, industrial and commercial environments, the need for independently verified cybersecurity assurance is becoming a core requirement. To help address this demand, Microchip Technology (Nasdaq: MCHP) has been certified by UL Solutions to the IEC 62443‑4‑1 Maturity Level 2 (ML2) Industrial Automation and Control System standard, demonstrating that its new product development process meets globally recognized secure by design criteria. The certification provides audit-backed assurance that products are developed under a mature, repeatable and independently verified cybersecurity framework.

The IEC 62443‑4‑1 standard defines the requirements for a secure development lifecycle (SDL), including threat modeling, secure design practices, rigorous implementation controls, verification and validation, and long‑term defect and patch management. UL Solutions’ certification confirms that Microchip integrates security into its hardware and software from initial design through end‑of‑life, and that these practices are consistently applied across business units and global design and manufacturing centers.

This level of audit‑backed assurance helps customers simplify their own cybersecurity evaluations, reduce supply‑chain risk and accelerate readiness for emerging regulatory requirements such as the EU Cyber Resilience Act (CRA).

“Achieving IEC 62443‑4‑1 ML2 certification reflects Microchip’s long‑standing commitment to rigorous security practices,” said Nuri Dagdeviren, corporate vice president of Microchip Technology’s secure computing group. “Customers need partners who can demonstrate secure development maturity, not simply claim it. This independently validated certification strengthens trust, reduces risk across the hardware–firmware stack and supports our customers as they work toward CRA and other standards‑based compliance.”
