Frequently Asked Questions

How do I upload my policies to Dexter?

Dexter offers two types of uploads: Assisted and Manual. Assisted uploads allow users to securely integrate their policy data (free of PII) with Athenium Analytics products. Our team can format and upload your policy and claims data, as well as establish connections for regular data updates. There is no size limit and the data is accessible any time you use Dexter.

Manual uploads allow users to import policy data themselves by uploading a .CSV file inside the Dexter interface. The manual upload process supports up to 50,000 lines of policy and location data. Manually imported .CSV data will disappear when the user logs out, therefore the file must be re-uploaded during each new session.

How does Athenium Analytics source Dexter's hail data?

Dexter hail insights are created with data from a variety of sources, including the National Oceanic and Atmospheric Administration (NOAA). Data sources include hail estimates produced by the Multi-Radar/Multi-Sensor system (MRMS), the Storm Prediction Center (SPC) and the National Climatic Data Center (NCDC).

Athenium Analytics algorithmically aggregates multiple data sources to provide the most accurate estimate of hail size at the highest resolution available.

Are wildfire events available for review in Dexter?

Yes, users can review wildfire events by name going back to March 2017. As with all other perils, the area of impact is plotted on a high-definition map and policy data is integrated within the application. Reports with maps can also be exported as PDFs.

Can Dexter Reports be created for time periods longer than a single day?

Yes, Dexter Event Reports provide granular weather data for a single day, but you can also create a Seasonal Report using a user-defined start and end date or a Historical Report which provides all historical occurrences for each peril at a specific location. Downloads and exports are available for each type of report.

Can reports be downloaded for more than one location at a time?

Yes, using Dexter Batch Reports, a user can upload up to 50,000 locations and dates through a CSV formatted file and determine whether any of eight perils occurred.  Each incident can then be further investigated through Dexter Reports individually.
