Frequently asked questions

Why do teams switch from Green Hills Software INTEGRITY?

Primary triggers are high licensing costs for large-scale deployments and concerns over vendor lock-in, especially in industries like aerospace or automotive where long-term flexibility and certification control matter.

Does PikeOS meet the same safety standards as INTEGRITY?

Yes. PikeOS is certified to the highest safety and security standards, including ISO 26262 (automotive), DO-178C (avionics), and IEC 61508, matching INTEGRITY’s compliance profile for critical systems.

Is PikeOS fully EU-hosted and GDPR-compliant?

PikeOS is developed and maintained in Europe, with data processing and storage controlled within the EU. It aligns with GDPR requirements for data sovereignty and processing transparency.

How does PikeOS compare on pricing to Green Hills Software?

PikeOS typically offers more predictable, transparent pricing models without the hidden costs that can inflate long-term INTEGRITY deployments. Exact figures depend on deployment scale and certification needs.

Can I migrate existing INTEGRITY applications to PikeOS?

Migration is feasible but requires adaptation, as PikeOS uses a different architecture. SYSGO provides tools and support to assist with porting applications, particularly for safety-critical use cases.

What’s the best European alternative to Green Hills Software for safety-critical systems?

PikeOS is the leading European option, offering a certified microkernel RTOS with comparable safety credentials, EU-based development, and stronger control over deployment and compliance.
