SEALSQ has announced VaultIC409, a secure element built on its QS7001 platform and designed to support post-quantum algorithms alongside RSA and ECC. The company plans to demonstrate it at Electronica in November 2026, while engineering samples are expected in the second quarter of 2027; certification and performance details remain outstanding.
SEALSQ has announced VaultIC409, a secure element designed to support post-quantum cryptography in connected devices while allowing manufacturers to retain their existing hardware security architecture, according to the company. Built on SEALSQ’s QS7001 platform, it is designed to handle ML-KEM and ML-DSA as well as RSA and ECC, giving device makers an option for combining newer and established cryptographic methods.
VaultIC409 is designed for the markets served by SEALSQ’s VaultIC408 product. The company says the new device combines a hardware Root of Trust, cryptographic agility, dedicated cryptographic acceleration and a Serial Peripheral Interface (SPI). SEALSQ says these features are intended to protect cryptographic assets and support secure identities, device authentication and secure communications.
The product is designed to support ML-KEM (FIPS 203) for key establishment and ML-DSA (FIPS 204) for digital signatures, alongside RSA and elliptic-curve cryptography (ECC). SEALSQ says the SPI interface is intended to accommodate the larger keys, signatures and certificates associated with post-quantum cryptography. The announcement does not provide performance figures, product pricing or a full technical specification.
SEALSQ plans to demonstrate VaultIC409 through a TLS 1.3 application at Electronica, scheduled for November 10–13, 2026. The company says engineering samples are expected in Q2 2027, for customer and partner evaluation. The underlying QS7001 platform is undergoing Common Criteria EAL5+ certification; SEALSQ has not announced that certification as complete.
Adding Post-Quantum Options to Devices
VaultIC409 is aimed at manufacturers that need to plan for cryptographic standards designed to resist attacks from sufficiently capable quantum computers. RSA and ECC are widely used today, but quantum computing presents a potential long-term threat to these methods. The timing and practical reach of that threat remain uncertain, while devices designed for long service lives may need security choices made well before deployment.
SEALSQ’s stated compatibility with both post-quantum and classical algorithms could let manufacturers evaluate hybrid approaches rather than replace all existing security at once. The company’s claim that customers can use the device without redesigning their hardware security foundation may lower integration barriers, but the announcement does not independently establish how easily it will fit particular products. Customers will need technical documentation and samples to test compatibility, performance and power use.
The announcement is also an early product milestone, not evidence that the device is already available for deployment. The demonstration is planned for November 2026, and sample availability is projected for 2027. Certification status, implementation details and customer adoption will help determine whether the product can meet manufacturers’ requirements.

From VaultIC408 to QS7001
VaultIC409 extends SEALSQ’s VaultIC secure-element portfolio, and the company says it targets the same established markets as VaultIC408. A secure element is a hardware component used to store sensitive credentials and perform security-related operations in a protected environment. SEALSQ describes VaultIC409 as an option for connected-device manufacturers in areas including smart energy, industrial equipment and the Internet of Things.
The announcement reflects a practical issue in adopting post-quantum cryptography: some algorithms use larger keys and signatures than traditional methods, which can increase demands on device storage, communications and processing. SEALSQ says dedicated acceleration and SPI connectivity are intended to address those embedded-device demands. Its statements describe the product’s design goals; the release does not provide independent test results or quantified comparisons with VaultIC408.
SEALSQ CEO Carlos Moreira linked the product to anticipated security requirements in the United States and European Union. The company did not identify specific rules, deadlines or compliance obligations in the announcement, so the regulatory rationale should be read as the company’s framing rather than a detailed account of new requirements.
“VaultIC409 offers customers “a direct path to post-quantum security on a certified platform they already know.””
— Carlos Moreira, SEALSQ founder and CEO
Certification and Product Details Pending
Several points remain open. SEALSQ says the QS7001 platform is undergoing Common Criteria EAL5+ certification, but has not said when the process will conclude or confirmed certification. The announcement also does not specify VaultIC409’s production schedule, price, power consumption, memory capacity, supported algorithm parameters or measured performance.
The company has not provided independent validation of its security claims or named customers integrating the product. Its statement that manufacturers can avoid redesigning their hardware security architecture is a product claim; compatibility will depend on individual designs and should be assessed when technical materials and samples are available. The announced dates are plans, and could change.
Electronica Demo and Sample Evaluations
The next public milestone is SEALSQ’s planned VaultIC409 demonstration at Electronica, November 10–13, 2026, using a TLS 1.3 application. The demonstration may provide more detail about how the device handles secure communications, but the announcement does not specify which performance or interoperability results will be shown.
SEALSQ expects engineering samples in Q2 2027 so customers and partners can evaluate the component and begin integration work. Further updates on certification, technical specifications and sample availability will be needed before manufacturers can judge its fit for particular devices or product schedules.
