FAQs
What is Master Data Guard™?
Master Data Guard™ is an automated, continuous monitoring solution for your vendor master file – the database of supplier bank account details used to process payments.
It works by:
- Comparing current vendor data against previously validated versions to detect any changes
- Validating new or changed account information when updates are identified
- Sending immediate alerts to stakeholders when unauthorized or unvalidated changes are found
Example: An attacker who has gained access to your ERP system changes a supplier’s bank account number. Before any payment is made, Master Data Guard™ flags the change and notifies your designated finance team members.
Why isn't existing access control or approval workflow enough?
Access controls and approval workflows manage who can make changes – they don’t verify whether the changed data is accurate or legitimate.
The gap:
- An insider with legitimate system access can alter vendor details without triggering access alerts
- An attacker who has stolen credentials looks identical to a legitimate user
- Approval workflows rely on humans reviewing changes – and humans can be socially engineered
Master Data Guard™ addresses this by validating the data itself, independently of who made the change or who approved it.
How frequently does it scan vendor data?
On any schedule that fits your operations:
- Continuous sync via ERP integration – detects changes in near real-time
- Pre-payment run – triggered automatically before each payment batch
- Scheduled intervals – daily, weekly, or custom cadence via the nsKnox portal
What does "end-to-end" protection mean?
It means every stage of the outgoing payment process is covered:
Vendor onboarding – new suppliers are validated before they’re added to the master file
Ongoing master data – vendor records are continuously monitored for unauthorized changes
Pre-payment – every transaction is scanned before the payment batch is released
Post-alert – any discrepancy triggers an immediate alert so teams can investigate before funds move
