TISAX VDA ISA: Automotive Supply Chain Prototype Protection
Configuring network perimeters for Trusted Information Security Assessment Exchange (TISAX) compliance, safeguarding prototype CAD data.
Regulatory Context & Scope
TISAX provides a standardized security assessment standard for European automotive manufacturers and supply chain partners.
Key Required Network Controls
Protection of Prototype CAD Data: Enforcing deep packet inspection and egress data leak prevention on engineering VLANs.
Third-Party Supplier Segregation: Isolating external automotive suppliers into restricted microsegments with dedicated WireGuard tunnels.
Continuous Incident Detection: 24/7 logging of perimeter connection anomalies to detect industrial espionage attempts.
Redundant Multi-Site Connectivity: Ensuring uninterrupted secure communication between global automotive testing facilities.
Technical Implementation Checklist
Position 4CGuard at external ingress/egress boundaries to enforce TISAX access policies.
Isolate regulated database enclaves and sensitive endpoints into dedicated VLANs.
Inspect application payloads for threats while applying compliance bypasses for privacy.
Stream CEF/Syslog telemetry to SIEM to maintain 100% verifiable TISAX compliance records.
TISAX - Compliance FAQs
Common auditor, technical, and implementation questions.
4CGuard automates rule verification, enforces zero-trust access, encrypts data in transit, and exports audit logs mapped directly to TISAX controls.
Evaluate 4CGuard on your network topology
Schedule an architectural walkthrough with a network security engineer. Review Layer 7 inspection rules, encrypted payload decapsulation, and Active Directory policy integration.
