Large cash advances or transfers that are not ordinary in the way that the cardholder spends can cause alerts.
Transactions that are not present on the card but frequent
A sudden increase in card-not-present transactions (online or over the phone purchases) with no prior history of such transactions could be a red flag for a review.

Security concerns. If evidence suggests security breach, such as unauthorized access, or data breaches that affects the card's details and/or unusual spending patterns, then the card will be identified as a security risk.
Identity Verification Issues. If there's a problem in verifying a cardholder's ID when making transactions (especially when additional verifications are needed) it is possible that the card will be temporarily blocked.
Card that was lost or stolen - The issuer may stop the card in the event that the cardholder reports it as missing or stolen. This prevents unauthorised use of the cards until the replacement card is received.

Gathering information from a variety of sources, such as threat intelligence feeds, forums, dark web monitoring, and security advisories, to stay informed about the latest security threats and security vulnerabilities.
Network Monitoring and Intrusion Detection
Software and tools that monitor the network traffic to identify suspicious activity, anomalies, or other indications of unauthorised access.
Assessments of vulnerability and penetration testing
Regularly conducting assessments to find weaknesses. Testing penetration tests mimic attacks in order to identify vulnerabilities and assess an organization's security posture.
Security Information and Event Management Systems (SIEMs)
Implementing SIEM solutions to collect and analyze logs gathered from different sources, such as servers and firewalls, to identify and respond to security breaches immediately.
Behavioral Analysis
