TARA & Threat Modeling
Both platforms offer automated TARA capabilities, but differ in approach. ThreatZ uses LLM-driven intelligence with a knowledge graph, while PlaxidityX relies on a proprietary threat catalog built from OEM engagements.
ThreatZ
- AI generates threats, attack paths, and risk ratings automatically
- Knowledge graph connects assets, threats, controls, and compliance in one model
- STRIDE, attack trees, and custom methodologies supported
- Incremental re-analysis as architecture evolves
PlaxidityX
- Security AutoDesigner with AI and proprietary threat catalog
- Claims 60–80% reduction in manual TARA effort
- Proprietary catalog built from OEM engagements; extensibility not publicly documented
- No unified knowledge graph; TARA, SBOM, and V-SOC are separate tools
CSMS & Compliance
Managing a Cybersecurity Management System (CSMS) requires more than individual tools. Teams need a platform that tracks the full compliance lifecycle, not just point-in-time assessments.
ThreatZ
- Purpose-built CSMS platform managing the full management system lifecycle
- ISO/SAE 21434, UNECE R155, and GB 44495 automated reporting
- End-to-end traceability from asset to control to evidence
- One-click audit report generation across all standards
PlaxidityX
- Consulting-led CSMS approach, supported by individual DevSecOps tools
- ISO/SAE 21434 & R155 compliance via tools + consulting engagement
- No GB 44495 support documented
- Compliance evidence spans multiple modules within the DevSecOps platform
Architecture & Deployment
PlaxidityX offers a full-stack approach spanning design-time tools, embedded runtime agents, and cloud SOC. ThreatZ focuses on the design-time and compliance layer as a modern SaaS platform.
ThreatZ
- Cloud-native SaaS with self-serve onboarding
- On-premise and hybrid deployment available
- SSO/SAML, Jira, Azure DevOps, and REST API integrations
- Open APIs — no vendor lock-in, standard data formats
PlaxidityX
- Full-stack: design-time + embedded runtime + cloud SOC
- Enterprise-heavy deployment; no self-serve SaaS option
- Integrations with Marvell, Elektrobit, dSPACE (hardware-centric)
- Bundled ecosystem may require buying capabilities you don't need
Vendor Independence & Pricing
PlaxidityX is part of Aumovio (spun off from Continental in 2025), a major Tier-1 automotive supplier. Some OEMs and competing Tier-1s may have procurement concerns about Tier-1 ownership of their cybersecurity tooling.
ThreatZ
- Independent, vendor-neutral — no supply chain conflicts
- Flat-rate Team plan from $1,199/month or per-user Professional from $499/user/month
- Up to 3 projects (Team), 15 (Pro), unlimited (Enterprise) — extra at $99/mo each
- Self-serve onboarding, no mandatory consulting engagements
PlaxidityX
- Aumovio subsidiary — some OEMs may have procurement concerns
- Enterprise pricing only, no published rates
- Per-vehicle licensing for embedded products adds to total cost
- Typically bundled with consulting and services engagements
Why Teams Choose ThreatZ over PlaxidityX
Organizations choose ThreatZ when they need a focused, vendor-neutral CSMS and TARA platform without committing to a full-stack embedded cybersecurity suite.
Vendor-Neutral
ThreatZ is an independent platform with no Tier-1 supplier ownership. Some OEMs prefer vendor-neutral tooling when evaluating sensitive cybersecurity data.
Purpose-Built CSMS
PlaxidityX delivers CSMS primarily via consulting. ThreatZ is a software platform that manages the full CSMS lifecycle — from asset inventory to compliance evidence — in one tool.
Modern SaaS
Cloud-native with self-serve onboarding, no enterprise deployment cycles. Start evaluating in days, not months of procurement and consulting kickoff.
Global Compliance
ISO/SAE 21434, UNECE R155, and GB 44495 compliance out of the box. PlaxidityX requires supplementary consulting for multi-standard coverage.
Predictable Cost
Transparent pricing with generous project limits across all tiers. No per-vehicle embedded licensing, no mandatory consulting bundles, no enterprise-only pricing gates.
Buy Only What You Need
PlaxidityX bundles IDPS, SOC, and design-time tools into one expensive suite. ThreatZ focuses on CSMS and TARA — pair it with any runtime solution you prefer.
