How to protect T&E systems from Cybersecurity Threats

T&E systems store some of the most sensitive data in your organization — credit card transactions, employee PII, travel schedules, and expense approvals — making them prime targets for phishing, ransomware, and insider threats. Non-compliance with GDPR, SOX, or PCI DSS can result in fines ranging from tens of thousands to millions of dollars. Yet 43% of IT leaders cite phishing and social engineering as critical vulnerabilities in T&E environments, and 29% flag inadequate employee training as an unaddressed gap, according to SAP Concur Research, Action for Growth: IT Leader Edition.

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.
