AP Security Assessment

Protecting the financial processes behind complex organizations

Our AP Security Assessments are designed for organizations with complex Accounts Payable, procurement, vendor management and payment environments.

We conduct controlled and pre-approved security simulations to identify weaknesses in invoice processing, supplier onboarding, approval workflows, payment verification and resistance to invoice fraud and social engineering.

Designed for organizations where financial controls matter

Our approach is particularly relevant to large organizations operating across:

Retail & FMCG
Ahold Delhaize · Heineken · Unilever

Banking & Financial Services
ING · ABN AMRO · Rabobank · Adyen

Technology & Digital
Philips · ASML · NXP Semiconductors · Booking.com · Prosus

Logistics, Shipping & Transportation
Maersk · DP World · KLM · PostNL · Schiphol Group

Real Estate & Infrastructure
CBRE · Prologis

Typical enterprise environment

Our assessments are suited to organizations with:

  • Large and decentralized supplier networks
  • High volumes of invoices and payments
  • Complex procurement and P2P processes
  • Multiple approval levels and financial mandates
  • International vendor and payment structures
  • ERP-based AP environments
  • High exposure to invoice fraud and Business Email Compromise (BEC)
  • Multiple entities, business units or operating countries

Our assessment covers

Vendor onboarding & verification
Testing whether fraudulent or manipulated supplier information can enter the vendor master process.

Invoice security
Assessing controls around invoice legitimacy, manipulation, anomalies and duplicate invoices.

3-Way Matching
Testing the effectiveness of controls between purchase orders, contracts, goods/services received and invoices.

Approval & authorization
Assessing approval workflows, delegation structures, segregation of duties and authorization thresholds.

IBAN & payment verification
Testing controls around supplier bank-account changes and payment verification.

Fraud & social engineering resilience
Controlled simulations designed to assess how AP and finance teams respond to realistic fraud scenarios.

Controlled. Authorized. Measurable.

All assessments are performed within a predefined scope and under explicit authorization. Testing is designed to identify control failures without causing operational disruption.

The result is a clear view of where an organization is vulnerable — and which controls should be strengthened before a real attacker exploits them.
