Capabilities · Security Engineering
Secure boot chains, Arm TrustZone partitioning, HSM integration, crypto libraries and engineering support for ISO/SAE 21434, UNECE R155 and the EU Cyber Resilience Act, for embedded products built in India.
Each card lights where it sits on a secure device, from the root of trust in the boot ROM to the update server and the obligations that last the product’s whole life.
Every stage verifies the next, from the boot ROM to the application.
Hardware-enforced isolation between secure and non-secure worlds.
Keys kept in tamper-resistant hardware, crypto offloaded to it.
The right algorithms, the right library, and keys that stay put.
Engineering support for OEMs and suppliers through threat analysis and type approval.
For products with digital elements sold in the EU.
It starts with what an attacker would want and ends with a plan for vulnerabilities found after launch. Hover a stage to find it on the line.

SEGGER and Perforce
Secure-boot and crypto libraries, secure production programmers and static analysis, from GSAS in India, with INR quotes, GST invoices and local support.
Tell us the silicon, the market and what must be protected. GSAS replies from Bengaluru with scope and a proposal: threat model, boot chain, isolation, keys and the evidence to go with them.
Secure boot chains, Arm TrustZone and TEE configuration, HSM integration and key provisioning, crypto library integration, and engineering support for ISO/SAE 21434, UNECE R155 and the EU Cyber Resilience Act.
Yes. GSAS implements a chain of trust from the boot ROM to the application: image signing and verification, anti-rollback counters, and secure OTA updates with A/B failover, using SEGGER emSecure and emBoot-Secure or the silicon vendor’s own mechanisms.
Arm Cortex-M23, Cortex-M33 and Cortex-M55 through SAU and IDAU configuration, and Cortex-A devices with Trusted Firmware-A, including secure and non-secure memory and peripheral partitioning.
GSAS supports OEMs and suppliers with threat analysis and risk assessment, cybersecurity concepts and requirements, CSMS documentation support and vulnerability management planning. Type approval itself rests with the vehicle manufacturer.
Under Article 71(2), the Article 14 reporting obligations apply from 11 September 2026 and the Regulation applies in full from 11 December 2027. GSAS helps manufacturers with gap assessment, secure development, vulnerability handling, SBOMs and technical documentation.
Yes. GSAS supplies SEGGER emSecure, emCrypt and Flasher Secure as an authorized SEGGER engineering partner in India, and Perforce Klocwork and QAC and Razorcat TESSY, with INR quotes and GST invoices.
