Case Study: Driving Cyber Resilience in the Auto Industry

How Automotive Suppliers Can Cut Cyber Insurance Premiums by 60% with Antigen Security

Industry Example: Automotive Manufacturing & Supply
Company Size: 2,100 employees
Annual Revenue: $1.4B
Cyber Insurance Premium (Before): $880,000/year Estimate.
Cyber Insurance Premium (After): $352,000/year Estimate.
Savings: 60% reduction through cybersecurity maturity and continuous controls monitoring

The Challenge

A Tier 1 automotive parts supplier was grappling with rapidly rising cyber insurance premiums. Despite having traditional cybersecurity tools in place—endpoint protection, firewalls, and periodic audits—their insurer had flagged them as “high risk” due to:

  • Inconsistent visibility across OT (operational technology) and IT environments

  • Limited incident response capabilities

  • No formal continuous monitoring or threat detection

  • A lack of detailed reporting to demonstrate cyber hygiene maturity to underwriters

Faced with increasing pressure from both OEM partners and insurance carriers, the CIO and CISO sought a way to harden their security controls and prove it to insurers—without adding overhead to their already lean security team.

The Antigen Security Solution

Working with Antigen Security, the supplier implemented a suite of lightweight, continuous monitoring controls tailored for hybrid OT/IT environments:

  • Security Controls Validation: Antigen deployed its agentless platform to validate that key controls—MFA, backup integrity, secure remote access, and vulnerability patching—were consistently enforced across systems.

  • Continuous Attack Surface Monitoring: External and internal threats were continuously monitored, mapped, and prioritized using Antigen’s real-time threat intelligence integrations.

  • Insurer-Focused Reporting: The company leveraged Antigen’s reporting engine to generate underwriter-ready compliance documentation and risk scores aligned with major insurance frameworks like NIST, ISO 27001, and CIS.

  • 24/7 Response Readiness: The built-in playbooks and drill simulations helped demonstrate that the supplier was ready to contain and recover from cyber incidents in hours, not days.

 

The Outcome

Immediate Security Impact
Within the first 30 days, Antigen’s platform identified several misconfigured VPN endpoints, expired certificates in a third-party vendor portal, and out-of-date software in factory floor PLCs—risks that had gone undetected for months. These were remediated within weeks thanks to prioritized alerts and automated guidance.

Insurance Premium Reduction
When the time came to renew cyber insurance, the supplier presented Antigen’s insurer-specific reports, control evidence, and real-time risk scorecard to their broker. After shopping quotes from four carriers, they secured a policy with 60% lower premiums and improved coverage—including ransomware and business interruption clauses.

Operational ROI

  • $528,000 in annual premium savings

  • No need to hire additional analysts

  • Streamlined compliance with upcoming SEC disclosure rules and supplier audits

  • Improved trust with OEM clients and strategic partners
