Audit & Penetration Testing: Anticipate attacks, manage risks.
In the face of increasingly targeted and sophisticated cyber threats, it is crucial to identify your vulnerabilities before attackers do.
Our security audit and penetration testing (pentest) services are designed to thoroughly assess the robustness of your information systems. Using a rigorous methodology and proven technical expertise, we help you strengthen your defenses, ensure regulatory compliance, and secure your critical assets.

PASSI & LPM Audit
Protect what matters most; meet the most stringent requirements.
Against a backdrop of increasingly targeted cyber threats and an increasingly stringent regulatory framework, the PASSI & LPM Audit has become an essential pillar for Operators of Vital Importance (OVIs) and exposed entities.
SCASSI is certified across all five product lines and performs a large number of PASS LPM audits thanks to one of the highest production capacities in the market.
- Organizational audit: Assessment of your procedures, ISG governance, incident management, and employee awareness.
- Physical audit: Inspection of sensitive areas, access controls, surveillance, and intrusion risks.
- Architecture audit: Analysis of network segmentation, critical traffic flows, and sensitive areas.
- Configuration audit: Verification of system configurations (OS, network equipment, hypervisors) in accordance with security best practices.
- Source code audit: Manual and automated analysis of critical code to detect software vulnerabilities.
As a qualified service provider or expert partner, we conduct these audits using a certified, methodical, and fully independent approach.

Comprehensive Cybersecurity Audit
Ensure your systems are compliant, from documentation to monitoring.
A comprehensive assessment of your security posture (technical, organizational, and regulatory), based on international standards.
Objective: to identify weaknesses, assess risks, and provide concrete recommendations.

Penetration Testing Audit - Embedded Systems & Industrial Environments
Protect your critical systems with the industry’s leading experts.
As embedded systems and industrial environments (OT/ICS) become increasingly connected—and therefore vulnerable—cybersecurity can no longer be an option.
At SCASSI, we have made the security of embedded and industrial systems our specialty.
Cybersecurity in embedded systems must be built in from the design stage (security by design) and maintained throughout the devices’ lifecycle. The rapid evolution of threats requires constant monitoring and the adaptation of defense strategies.
Our strength lies in our specialization:
→Expert penetration testers for critical systems
Our teams work on the most sensitive systems:
• Satellite ground segments
• Industrial networks
• IoT / Cloud / Mobile environments
• Embedded systems in automotive and avionics
→ In-depth expertise in embedded and industrial systems
We know where to look for vulnerabilities. Communication buses (CAN, UDS, Modbus, UART…), firmware, physical interfaces: our methods are designed to detect even the most subtle flaws.
Our Key Services: Penetration Testing
Mapping and Analysis of the Attack Surface
• Firmware reverse engineering
• Resilience testing (physical, network, and protocol attacks)
• Concrete technical and strategic recommendations

An offensive approach - Red Team - Embedded systems & industrial environments
Think like an attacker. Test your defenses. Secure your critical systems.
Traditional testing is no longer enough. To uncover your true vulnerabilities, you need to adopt an offensive approach—the attacker’s perspective.
At SCASSI, we offer Red Team exercises tailored for industrial (OT/ICS) and embedded environments.
What we're testing is your reality:
• Physical or network intrusion at an industrial site
• Exploitation of vulnerabilities in embedded firmware
• Protocol hijacking (CAN, Modbus, UART, etc.)
• Stealthy persistence in critical systems
• Exfiltration of sensitive data via an OT/IT chain
Why a Red Team?
Because a system can be compliant... yet still vulnerable.
Because no architecture is immune to a realistic, targeted attack.
Because you need to validate your detection, response, and resilience capabilities—not just your defenses.
Pentest + Red Team Bundle
Need a hybrid approach? We combine in-depth technical audits (firmware, configuration, attack surface) with Red Team scenarios to cover your entire actual exposure

Specialized expertise
• Vulnerability Scans: Automated analysis of your networks, systems, and applications to quickly identify exploitable vulnerabilities.
• Web Penetration Testing: In-depth testing of your web applications (SQL injection, XSS, SSRF, etc.) to prevent the most common attacks.
• Mobile Penetration Testing: Security assessment of your mobile apps, from code to network communication.
• Internal Network Penetration Testing: Simulation of attacks from within to test resilience against internal threats or compromises.
• Industrial Penetration Testing (OT/ICS): Analysis of industrial systems and specific protocols to prevent critical disruptions or malicious intrusions.
• IoT/Embedded Penetration Testing: Securing connected devices and embedded systems, from firmware to cloud infrastructure.
• PACS Audits: Regulatory audits for healthcare organizations (OSEs), in accordance with ANSSI standards, ensuring compliance and the robustness of security measures.
