Build security in, don’t bolt it on. Our experienced engineers help you secure Linux platforms across ARM and RISC-V embedded devices, enterprise servers, and cloud-connected systems, with real expertise at every layer of the stack.
The Challenge: Security Is a Lifecycle, Not a Feature
Whether you’re shipping embedded devices, managing enterprise Linux servers, or connecting systems to the cloud, security failures disrupt operations, compromise user data, and erode trust.Development and operations teams regularly face challenges such as:
Escalating vulnerabilities. CVE management burden grows with every layer added to the software stack.
Platform attacks before the OS loads. Firmware, boot-chain, and physical access threats can bypass OS-level defenses entirely.
Data theft and tampering. Unauthorized access, storage breaches, and data compromised in transit put your users and your business at risk.
Network infiltration and lateral movement. Initial breaches can expand quietly across infrastructure before they are detected.
Cloud exposure and blind spots. Misconfigurations, insufficient monitoring, and delayed incident response leave threats undetected.
Security isn’t solved once. It must be built in, maintained, and enforced continuously. RISCstar provides the engineering expertise to make it a practical reality across embedded, server, and cloud environments.
RISCstar's Approach to Linux Platform Security
We combine deep knowledge of security fundamentals with applied engineering expertise across every layer of the Linux stack.RISCstar secures platforms including:
Hardware & Platform Security
We implement hardware roots of trust using TPM, HSM, and fuses, including firmware TPMs running in isolated environments on the main CPU, and deliver secure boot, debug lockdown, and firmware attestation to protect the platform before the OS loads.
Operating System Security
We enforce SELinux and AppArmor policies, apply memory and control-flow protections, harden least-privilege configurations, and manage the full CVE response and patch lifecycle to keep your OS hardened and current.
Network & Infrastructure Security
We implement zero-trust network segmentation using firewalls, VLANs, VPN, and MFA, deploy intrusion detection and prevention systems, and secure cloud connectivity and identity services end to end.
Application & Data Security
We harden APIs and input validation, enforce RBAC and secrets management, and ensure data is encrypted at rest and in transit, including per-device key generation and encrypted partition architectures that support factory reset by deleting keys and recreating partitions from scratch.
Monitoring & Incident Response
We integrate SIEM, build threat detection and response workflows, and ensure your systems are forensics-ready so when incidents occur, you respond fast and recover faster.
Continuous Security Improvement
We embed lifecycle planning, automation, and vulnerability response into your engineering workflows so security becomes sustainable, not a patch-by-patch scramble.
Why RISCstar?
Securing a Linux platform requires expertise that spans hardware, OS, network, and application layers and the operational experience to make it work in the real world, not just on paper.Our engineers bring:
End-to-end security architecture across embedded, server, and cloud environments
Deep Linux platform specialization that reduces reliance on generic security vendors who don't know the stack
Hardware-aware and application-aware expertise that eliminates weak spots at system boundaries from TPM and secure boot to encrypted partitions and API hardening
Operational security experience with proven uptime and resilience in production environments
Knowledge transfer built into every engagement so your team grows stronger while we strengthen your security posture
We secure platforms, not just components.
Secure What You've Built and What You're Building Next
If your team needs to take better control of your Linux security posture across devices, servers, or cloud infrastructure, we can help
