Secure IoT. By Design. From chip to cloud.
WIZnet IoT devices and Peak Security Suite for IoT form the foundation of every NIS2- and CRA-compliant industrial IoT infrastructure. Hardware-anchored. Certificate-managed. Audit-ready.
▸ Deployed Annually
10M+
WIZnet-powered devices
Hardwired TCP/IP in silicon since 2001. De-facto standard in Arduino Ethernet Shield & Raspberry Pi RP2040.
The problem
Most IoT devices were designed before security was mandatory.
Four vulnerabilities put every unprotected industrial IoT device at risk today.
Software TCP/IP Stacks
Buffer overflow attacks can manipulate the network layer of any device running a software-based TCP/IP implementation — a structural weakness no patch can fix.
Default Passwords & Pre-Shared Keys
The single most exploited attack vector in industrial IoT. 60% of all documented OT breaches start with default credentials that were never changed.
No Certificate Infrastructure
Without cryptographic device identity, man-in-the-middle attacks are trivial. You cannot verify who is sending data — or whether it has been tampered with.
No Lifecycle Management
Firmware stays outdated. Certificates expire unnoticed. Compromised devices remain in the network. Average detection time: 197 days.
The solution
Hardware-anchored security. End to end.
WIZnet secures the data transport. The Peak Security Suite for IoT secures the device identity. Together, they close every gap.

The regulation is here. Are your devices ready?
WIZnet × Peak Security Suite for IoT is the only solution that addresses both NIS2 and the CRA at the hardware level.
In Force - October 2024
NIS2 Directive
Applies to ~160,000 companies across the EU. Board-level accountability. Fines up to €10M or 2% of global turnover for non-compliance.
✔ Access control for all OT/IoT devices
✔ Demonstrable risk management processes
✔ Incident response and audit trail
✔ Cryptographic verification of device identity
Mandatory - 2027
Cyber Resilience Act
Security-by-Design becomes law for all products with digital elements sold in the EU. Conformity assessment required before market placement.
✔ Security built into the product architecture
✔ Lifetime security updates mandatory
✔ Vulnerability disclosure obligations
✔ CE marking for connected products
