How to protect T&E systems from Cybersecurity Threats

2 business leaders are discussing cybersecurity strategy

Travel and expense (T&E) systems store credit card transactions, employee PII, travel schedules, and expense approvals — making them prime targets for ransomware, phishing, and insider threats. Non-compliance with GDPR, SOX, or PCI DSS can result in fines of tens of thousands to millions of dollars. In one documented case, a ransomware attack on an unpatched SaaS provider caused more than $10 million in damages.

According to SAP Concur research, 43% of IT leaders cite phishing and social engineering as the top vulnerabilities in T&E environments, and 29% flag inadequate employee training as a critical gap.

What to look for in a secure T&E platform?

  • Vendor certifications: ISO 27001 or SOC 2 Type II, with verified penetration testing and documented disaster recovery plans
  • Role-based access control (RBAC): Limits each employee to only the data their role requires, reducing insider threat exposure
  • AES-256 encryption: Protects sensitive data in storage and in transit, meeting GDPR, SOX, and PCI DSS requirements
  • Multi-factor authentication (MFA): Blocks unauthorized access even when credentials are compromised — via push notification, biometric scan, or dynamic token
  • AI-powered behavioral analytics: Flags anomalies such as unusually high expense claims or last-minute international travel bookings in real time
  • Zero-trust architecture: Continuously verifies user identity at every access point, including from public Wi-Fi networks

Securing T&E also requires the human layer: regular employee phishing simulations, automated fraud detection, and joint IT-finance cybersecurity audits. SAP Concur research shows 58% of IT leaders already prioritize this cross-functional collaboration.

SAP Concur provides a security-first T&E platform with continuous compliance updates, real-time spend monitoring, geo-redundant cloud protection, and access controls including SSO, MFA, SAML 2.0, and RBAC.

Frequently Asked Questions

What cybersecurity threats do T&E systems face? T&E systems are primary targets for phishing, ransomware, credential theft, and insider threats. Because they store credit card data and employee PII, they fall under GDPR, SOX, and PCI DSS compliance requirements. Non-compliance can result in fines from tens of thousands to millions of dollars, plus years of reputational damage.

What is zero-trust architecture in a T&E context? Zero-trust architecture requires continuous identity verification at every access point — whether the user is in the office or on a public Wi-Fi network. It operates on the principle that no user or device is inherently trusted, minimizing exploitation risk from unsecured networks and compromised credentials.

What is AES-256 encryption and why does it matter for T&E? AES-256 is a full-stack encryption standard protecting sensitive data both in storage and in transit. For T&E platforms, it ensures expense records, reimbursement transactions, and employee information are secured against breaches and aligned with GDPR, SOX, and PCI DSS mandates.

How does behavioral analytics detect T&E fraud? AI-powered behavioral analytics establishes a baseline of normal spending behavior per user. Anomalies — unusually high expense submissions, last-minute international bookings, or activity outside regular working hours — are flagged for compliance or finance team review in real time.

How does SAP Concur protect T&E systems? SAP Concur embeds security controls directly into expense and travel workflows: RBAC, MFA, SAML 2.0 identity federation, real-time spend monitoring, geo-redundant cloud protection, and continuous compliance updates aligned with global data privacy regulations.
