Solution
Cybersecurity for Automotive. Inside Polarion. From TARA to Type Approval.
A vulnerability disclosed after SOP is still your problem, for the vehicle’s life. Nextedy brings TARA, CVSS and STRIDE into Polarion — on the same record as the requirements and tests they affect, not in a supplier’s spreadsheet.

Problem
The Core Question: How Much of Your Threat Model Survives Contact With a Live Vulnerability Feed?
General Safety-Critical Systems
30–60 %
High-Integrity Systems
60–80 %
Regulated IT/Automation Systems
40–70 %
Cybersecurity Requirements
80–100 %
Note: while examples are often from MedTech/Pharma due to clear standards, this principle applies broadly across safety-critical domains.
Threats Don't Wait for SOP — Your Risk Picture Shouldn't Either
A failure mode you catch in design stays caught. A vulnerability doesn't: new CVEs against telematics, infotainment, and OTA channels surface long after SOP, reopening a TARA you thought was closed.
Most teams track threats in spreadsheets that go stale the moment a disclosure lands — leaving your CSMS built on outdated data, across your ECUs and every supplier's.
Solution
Cybersecurity Risk Management Built for a Threat Landscape That Never Sits Still
Model Threats and Vulnerabilities, Not Just Hazards
Threats, vulnerabilities, assets, security goals, and security controls stay native Polarion Work Items — linked to your E/E architecture, ECU software, and test evidence. A threat profile sits next to the ECU it targets, not in a supplier's spreadsheet.
One threat register across ECUs and suppliers
Safety and security teams read the same record
Link TARA findings to the requirements they affect
Score and Triage Threats in a Spreadsheet-Simple Grid
TARA, CVSS scoring and STRIDE modeling in a spreadsheet grid — inside Polarion LiveDocs, across connected and OTA-capable systems.
No retraining for teams coming from supplier sheets
Triage threat lists across platforms and ECUs
Get real-time CVSS scores and risk visuals
Run TARA, CVSS, and STRIDE Side by Side
Whether you're running TARA per ISO/SAE 21434, scoring with CVSS, modeling with STRIDE, or prepping for a UNECE R155 audit, RISKSHEET offers fully customizable templates — no methodology lives in its own silo.
Use best-practice templates, or configure your CSMS
Apply consistent criteria across platforms and programs
Align supplier submissions before type approval
Automate the Path From Disclosure to Mitigation
Integrate vehicle cybersecurity risk management with Polarion's workflow engine, enhanced by RISKSHEET, so a disclosed vulnerability moves straight into triage.
Configure guided workflows for risk treatment
Support disclosure response with one always-current source of risk data
Every threat has an owner and a gate it must clear
Keep Pace With a Threat Landscape That Never Stops Moving
Unlike a hazard closed out in design, a vulnerability can resurface years into production. Polarion’s versioning shows how your threat model changed and when — so a judgement made before SOP is still defensible.
Track every revision as new vectors emerge
Baseline at program milestones, then re-baseline on a new CVE
Compare versions to spot rating changes
Prove Security to Regulators, Auditors, and Customers
Produce the documentation type-approval authorities, OEMs, and auditors need for CSMS audits and ongoing monitoring — with confidence, even after the threat picture has changed.
Export TARA, CVSS, and STRIDE reports from RISKSHEET
Keep documentation accurate across production life
Support monitoring with one current source of data

How Are Products Licensed?
As an annual software subscription. Active users of a given app need a Named Active User license for that product; a Connect license is required per server and gives every Polarion user read-only access to that app's views as a report. A commercial license covers one production instance on one Polarion server, including a load-balanced or multi-node cluster.
