Is Great Southern Bank supported?

Yes. Great Southern Bank connects through CDR Open Banking (via Fiskil), so you can link your accounts and start syncing in minutes.

How often does Great Southern Bank sync to Zerosum?

Syncs are event-driven: Great Southern Bank notifies Redbark via CDR webhooks when new data is available, and your Zerosum updates soon after, within a few hours of a transaction posting, with no fixed polling schedule.

Is my Great Southern Bank connection read-only?

Yes. Redbark requests read-only access under the CDR. It can read transactions and balances, and can never move money or change your Great Southern Bank accounts.

Does Redbark store my Great Southern Bank data?

No. Redbark uses a pass-through architecture: your Great Southern Bank transactions are proxied live to Zerosum. We store consent records, encrypted tokens and minimal account metadata, never transaction amounts, descriptions or balances.

Is Redbark independently security tested?

Yes. Redbark was penetration tested in July 2026 by Project Black, a CREST-accredited Australian security firm, covering the web app, REST API, MCP server and admin console. The test returned zero critical and zero high-risk findings, and every finding raised was remediated and confirmed closed on retest.

Which Zerosum plan supports Great Southern Bank sync through Redbark?

Zerosum’s bring-your-own-provider bank sync is included with Plus and Pro, including the Pro trial. Redbark Developer is 30% off while your Zerosum connection stays active.

Will Zerosum duplicate my Great Southern Bank transactions?

Zerosum runs SimpleFIN imports through its normal review, matching and duplicate-prevention flow. You control which Great Southern Bank provider accounts are linked to each budget account.
