Summary:
- Insurance companies use two distinct tools for risk analysis: Quick hazard scores for individual properties and complex catastrophe models for a long-term portfolio view.
- Fast hazard data for specific addresses acts as a clean input for the larger catastrophe models, a combination that produces a more precise picture of risk.
- This dual-model approach gives insurers consistent data for daily policy decisions and more credible information for major financial plans, such as reinsurance deals.

A Smarter Way to Balance Risk Decisions
Underwriting leaders need to assess property-level risk quickly while also preparing for portfolio-level conversations about capital and reinsurance. HazardHub complements catastrophe models by handling the front end—fast, address-level triage—while cat models provide the deeper, long-term view. Together, they deliver both speed and credibility.
With HazardHub Peril Scores and A–F Grading, underwriting teams can:
- Identify key perils in ~2 seconds for faster quote decisions.
- Route high-risk properties to specialized workflows or inspections.
- Reduce reliance on blunt proxies by using higher-resolution hazard scoring.
- Document underwriting calls with transparent, auditable inputs.
Tools That Support Every Risk Conversation
HazardHub pairs with existing models and risk frameworks through practical resources:
- HazardHub Variable Dictionary: mapped to hazard and vulnerability concepts for actuarial consistency.
- HazardHub Event-Verification Checklist: supports claims and catastrophe response.
- Triage vs. Portfolio RACI Guide: clarifies who uses which tool at which stage.
From Property Triage to Portfolio Oversight
HazardHub is designed for underwriting speed, while catastrophe models remain essential for capital planning and reinsurance. One-year policy horizons align with HazardHub’s rapid grading, while multi-year climate scenarios fit the cat-model and climate context. Used together, they ensure decisions are consistent, evidence-based, and explainable.
Portfolio Hygiene at Scale
Once HazardHub variables are integrated into the book, portfolio diagnostics become easier to run and interpret. Instead of relying only on high-level summaries, underwriters and actuaries can see where adjustments matter most.
The benefits include:
- One-way cuts that highlight underperforming cells and appetite mismatches.
- Peril-level clarity to tune underwriting rules and improve portfolio balance.
- Clean inputs that feed directly into the next cat-model run, improving accuracy.
This process strengthens both day-to-day underwriting and long-term capital conversations.
Climate Context for Stakeholders
Regulators and market stakeholders now expect climate risk to be part of everyday oversight. HazardHub provides property-level detail that makes these conversations clearer and easier to document.
Key benefits include:
- Regulatory alignment: supports climate disclosures such as NAIC surveys and TCFD frameworks.
- Credible storytelling: data explains why underwriting or pricing changes are needed.
- Market confidence: shows investors and policyholders that future risk is being measured and managed.
Supporting Reinsurance Decisions
Reinsurance renewals depend on clear, defensible data. HazardHub strengthens these discussions by reducing uncertainty at the property level and complementing catastrophe models.
With HazardHub, carriers can show:
- Address-level transparency: every property scored with consistent criteria.
- Credible aggregation: peril scores that feed directly into cat-model runs.
- Negotiation leverage: transparent data that improves confidence and reduces friction during pricing talks.
These advantages give reinsurers confidence that exposures are being managed systematically, positioning insurers as disciplined partners in a competitive capital market.
