Why Stritzinger?
At Stritzinger, we focus on the concrete parts of IoT security, from secure provisioning with untrusted suppliers to secure boot, disk and memory encryption, and mTLS-based communication. We look at hardware, firmware and backend together instead of treating security as a one-off checklist.
With experience in EU regulatory work, including the Cyber Resilience Act, and active involvement in the RESCALE project, we help you understand where your systems stand and what has to change. Our IoT security services aim to make your products defensible for audits while staying realistic about cost, risk and engineering effort.
Design Secure IoT Software
Protect your infrastructure with security measures that work from initial design to final deployment.
Establish Trust in Provisioning
Develop secure workflows, even with untrusted suppliers.
Protect Critical Data
Ensure secure boot, disk and memory encryption to shield your information.
Enable Reliable Connectivity
Build trusted networks with NAC protocols and mTLS communication.
Cyber Resilience and EU Compliance
Building systems that withstand attacks and meet EU rules
Cyber resilience means building IoT systems that keep running under attack and recover quickly after incidents. It goes beyond basic security checks to include threat detection, incident response and continuous monitoring. For European manufacturers this also means meeting regulatory requirements such as the Cyber Resilience Act, which requires security by design and ongoing vulnerability management for connected products.
Our approach to IoT security and cyber resilience covers hardware security, secure provisioning workflows, encryption at rest and in transit, and network access controls. We help you document your security measures, prepare for audits and maintain EU compliance as regulations evolve.
EU-Compliant IoT Security Services
We help manufacturers prepare for the Cyber Resilience Act and other EU IoT security regulations by reviewing your hardware, firmware and backend systems. Our audits identify gaps and provide concrete steps to achieve compliance.
Cyber Resilience in Practice
Beyond compliance, we design systems that detect threats, respond to incidents and maintain operations during attacks. This includes secure boot chains, encrypted storage, mTLS communication and automated certificate management.
Ongoing Security Management
Cyber resilience requires continuous attention. We provide regular reviews, security health reports and guidance on preventive measures to keep your systems aligned with EU standards over the product lifecycle.
Tailored Service Tiers
Every business has unique security needs. Our IoT security services offer three tailored tiers designed to fit your requirements, whether you're laying the groundwork for EU-compliant IoT security or safeguarding mission-critical infrastructure.
Essentials Security Assessment
A practical starting point for small IoT manufacturers or businesses that need a first EU IoT security review.
Hardware security review (secure boot, encryption).
Recommendations for supplier provisioning workflows.
Prioritised action plan for strengthening your security.
Lay the groundwork for a secure IoT system with cost-effective measures.
Advanced IoT Security Audit
In-depth audit and guidance for teams that need stronger cyber resilience and clear EU IoT security compliance support.
Full review of hardware, provisioning and secure boot.
Secure communication setup with mTLS and NAC, plus data encryption checks.
Compliance report for EU standards, including the Cyber Resilience Act, with follow-up consultation.
Strengthen your IoT systems with compliance-ready measures.
Enterprise IoT Security and Compliance Program
Ongoing security and compliance management for high-stakes environments.
Full hardware security implementation, from secure boot to encryption, key management and NAC.
Tailored provisioning workflows and operational procedures for manufacturing with limited supplier trust.
Regular reviews, security health reports and preventive guidance to maintain compliance over the product lifecycle.
Maintain security and compliance over the lifetime of your products, not just at launch.
FAQ
Do you only work with GRiSP and GRiSP.io?
No. We often recommend GRiSP and GRiSP.io for new designs, but most engagements start from the devices and infrastructure you already have. We also work with other hardware and software stacks.
Can we start small if we are not sure which tier we need?
Yes. Many clients start with a limited assessment or workshop. Once we understand your devices, networks and constraints, we help you decide whether Essentials, Advanced or a custom scope makes sense.
Do you do one-off audits or long-term support?
Both. Some teams want a one-time audit and report. Others, especially in regulated sectors, prefer a longer program with regular reviews and help preparing for the EU Cyber Resilience Act or similar requirements.
