Oasis Loss Modelling Framework
open-sourceOpen-source catastrophe loss modeling platform supported by the insurance industry.
Configurable run orchestration that turns prepared model components into standardized intermediate and output artifacts.
Oasis Loss Modelling Framework is built to execute end-to-end modeling runs using a staged configuration that maps inputs to computation steps and outputs. The framework supports location-level exposure handling through external exposure preparation, then couples those exposures to hazard intensity footprints and vulnerability functions during run execution. Outputs include event loss tables that can be aggregated for portfolio views and distribution measures used in risk decision workflows. The project also provides tooling to manage run configuration artifacts so the same workflow can be repeated across model versions and datasets.
A key tradeoff is that deeper model governance and data normalization depend on the surrounding pipeline, since the framework primarily executes what the inputs and mappings specify. Oasis Loss Modelling Framework fits best when a team already has structured exposure and model data in production formats and needs repeatable batch runs with controlled configuration. A typical usage situation is nightly or on-demand reruns where hazard or vulnerability updates must propagate consistently into portfolio loss curves without manual recalculation.
- +Config-driven workflow orchestration across hazard, vulnerability, and exposure inputs
- +Event loss table generation supports downstream aggregation and scenario comparisons
- +Batch execution suited for repeated reruns across model and data versions
- +Extensibility model components enable custom mappings into standard outputs
- –Operational maturity depends on disciplined configuration and data pipeline integration
- –Complex setups take time for teams without catastrophe data normalization experience
- –Model interpretation and analytics require additional downstream tooling for reporting
- –Debugging mismatched inputs can be time-consuming without strong run artifact tracking

Fathom
vertical specialistGlobal flood hazard and catastrophe risk data for insurance, banking, and government.
Run orchestration via API ties exposure updates to deterministic model execution and repeatable output sets.
Fathom is a catastrophe modeling solution built for operational use, where exposure updates and model re-runs must stay consistent across teams and time. The workflow maps inputs through hazard intensity footprints, vulnerability-based damage ratios, and an event loss table into downstream financial outputs. Integration depth is driven by its API-driven run lifecycle and data interchange patterns for exposure and job orchestration. This design favors organizations that need recurring modeling batches rather than ad hoc analysis.
A tradeoff appears in how teams must align their exposure preparation and model configuration to Fathom's expected run structure to get predictable throughput. Fathom fits best when there is a steady cadence of submission changes, such as portfolio rebuilds before renewal cycles. It is also suitable when multiple stakeholders need the same computed outputs with controlled access, because RBAC and change traceability reduce review overhead.
- +API-driven job runs reduce manual rerun work
- +Repeatable scenario outputs support audit trails
- +Exposure ingestion supports location-level workflows
- +Controlled access reduces accidental model changes
- –Model configuration requires disciplined setup before automation

How to Choose the Right catastrophe risk modeling software
Catastrophe risk modeling software turns hazard intensity inputs into vulnerability-aware loss outputs and then into aggregated risk metrics like average annual loss and loss exceedance curves. This guide covers Oasis Loss Modelling Framework, Fathom, KatRisk, One Concern, Verisk Touchstone Re, Moody's RMS Intelligent Risk Platform, Karen Clark & Company RiskInsight, EigenRisk EigenPrism, Jupiter Intelligence, and Mitiga Solutions.
The practical difference across these tools shows up in run orchestration, API-driven automation, and how each platform preserves configuration and run history from draft inputs to published outputs. Teams typically choose based on integration control for batch execution, governance depth for model risk management review, and the repeatability of event loss table generation and gross to net financial layer results.
Catastrophe risk modeling platforms for probabilistic and scenario loss production with governed run orchestration
Catastrophe risk modeling software provides workflows that convert exposure data and hazard footprints into vulnerability-adjusted event loss outputs and then through financial modules into reinsurance-ready gross and net loss results. In Oasis Loss Modelling Framework, configurable run orchestration packages prepared model components into standardized intermediate and output artifacts for repeatable batch runs.
Fathom focuses on API-driven job runs that tie exposure updates to deterministic model execution and repeatable output sets for controlled access across underwriting and risk. KatRisk extends that workflow concept end to end by carrying exposure mapping through hazard and loss computation into financial layer aggregation with reinsurance layer and policy term handling.
Run orchestration, automation surface, and governance artifacts for repeatable loss outputs
Catastrophe risk modeling software becomes usable at scale when run orchestration turns prepared model components into consistent intermediate and output artifacts that support repeatable event loss table generation. Without that run-level control, teams lose traceability when hazard inputs, exposure mappings, and vulnerability assumptions change between drafts and published results.
Automation and governance controls determine whether the workflow can run through recurring batches with controlled access. Platforms such as Fathom and Oasis Loss Modelling Framework reduce manual reruns with API-driven execution and configuration-driven job runs, while One Concern and Karen Clark & Company RiskInsight focus on model risk management review through configuration and run history records.

If run orchestration must standardize intermediate and output artifacts for repeatable batch runs, shortlist Oasis Loss Modelling Framework. If the organization needs run history and configuration records that support model risk management review without rebuilding documentation per study, shortlist One Concern.
Decide between API-first deterministic job runs or configuration-driven batch orchestration
If exposure updates must trigger controlled deterministic model execution via API job runs, shortlist Fathom. If repeatability depends on configuration-driven workflow orchestration across hazard, vulnerability, and exposure inputs, shortlist Oasis Loss Modelling Framework or Mitiga Solutions.
Validate that the platform’s workflow spans the same end-to-end chain the team uses
If exposure mapping must carry through hazard and loss computation into financial layer aggregation with reinsurance layer and policy term handling, shortlist KatRisk. If the team expects publishing workflows that preserve traceability across probabilistic model revisions, shortlist Karen Clark & Company RiskInsight.
Select based on reinsurance-layer output governance requirements
If the target output is reinsurance layer loss modeling with versioned model configuration for controlled scenario production, shortlist Verisk Touchstone Re. If governance includes managed model release operations that couple configuration with validation checks, shortlist Moody's RMS Intelligent Risk Platform.
Check how automation behaves under complex external data preparation needs
If the workflow depends on pre-shaped input files or disciplined setup before automation, treat Fathom and similar API workflows as a readiness test for input preparation. If the team anticipates external exposure attribute complexity, evaluate EigenRisk EigenPrism and Jupiter Intelligence for how their imports and iterative studies handle repeatable configuration-to-loss output generation.
Teams that need repeatable catastrophe studies with controlled access and review artifacts
Catastrophe risk modeling software fits teams that must run probabilistic catastrophe model workflows and scenario analysis repeatedly with controlled changes to hazard inputs, exposure mapping, and financial terms. Tools that emphasize run orchestration and traceability reduce drift between drafts and published results.

Common failure modes in catastrophe modeling workflows and integrations
A major failure mode occurs when teams treat catastrophe modeling outputs as one-off analyses instead of governed runs with standardized inputs and controlled configuration. That leads to inconsistent event loss table generation and loss exceedance curve outputs across iterations.
Another common issue is underestimating disciplined configuration and data pipeline integration needs for automation, especially when complex exposure attributes require external preparation. Tools differ in how strictly they enforce run discipline, how much workflow coverage they provide, and how they support audit-ready lifecycle control.
Allowing draft inputs to flow into production outputs without run discipline
Oasis Loss Modelling Framework requires disciplined configuration and data pipeline integration because complex setups take time without catastrophe data normalization experience. KatRisk also requires strict run discipline to prevent draft inputs entering production outputs.
Overestimating how much automation works without pre-shaped inputs
Fathom reduces manual reruns through API-driven job runs but some analysis steps depend on pre-shaped input files, which demands preparation discipline. Jupiter Intelligence combines deterministic scenario analysis and probabilistic outputs but integration work is required to align external exposure data and financial terms formats.
Building governance processes that depend on manual re-documentation per study
One Concern avoids per-study rebuilding by recording configuration and run history for model risk management review. Karen Clark & Company RiskInsight focuses on publishing workflows that preserve traceability across probabilistic model revisions.
Assuming reinsurance-layer workflow coverage exists without checking versioned configuration and layer outputs
Verisk Touchstone Re emphasizes reinsurance-ready layer loss modeling driven by versioned model configuration for controlled scenario production. Moody's RMS Intelligent Risk Platform couples governed model release operations with policy and reinsurance layer handling for gross-to-net calculations.
How We Selected and Ranked These Tools
We evaluated each platform on features, ease, and value, with features weighted at 40% and ease and value each weighted at 30%. Oasis Loss Modelling Framework ranked highest because configurable run orchestration turns prepared model components into standardized intermediate and output artifacts, which directly supports repeatable catastrophe batch runs and consistent event loss table generation.
We also assessed automation and control depth by comparing API-driven execution in Fathom against run-configuration governance artifacts in One Concern and managed model release operations in Moody's RMS Intelligent Risk Platform. We then used reinsurance workflow coverage as a tie-breaker by comparing Verisk Touchstone Re’s reinsurance-ready layer loss modeling with KatRisk’s end-to-end financial layer aggregation and gross-to-net reproduction.
