FiftyFive designed and deployed a custom File Integrity Monitoring solution for a regulated digital payment provider. The AWS-native architecture detects unauthorised file changes in real time without adding payment latency, while fail-safe redundancy and compliance alerting maintained 100% uptime throughout monitoring operations.
Build Your Platform With UsThe client is a regulated digital payment management provider serving businesses and consumers across financial markets. Its platform processes high-volume utility transactions with real-time settlement and required security controls that could scale without compromising throughput or compliance.
The payment platform required continuous, auditable file integrity monitoring that met financial regulations while leaving transaction throughput, latency, and uptime completely unaffected.
FiftyFive built a cloud-native File Integrity Monitoring solution that runs alongside the payment platform. A sidecar pattern isolates monitoring from transaction processing, AWS event-driven services detect changes instantly, automated workflows document compliance responses, and fail-safe redundancy prevents monitoring failures from affecting payments.
FiftyFive isolated file monitoring from payment execution paths through a sidecar deployment pattern.
FiftyFive used AWS-native events so file modifications trigger immediate evaluation instead of scheduled scans.
FiftyFive converted detection events into documented and actionable compliance workflows.
FiftyFive engineered the monitoring layer so component failure cannot interrupt payment processing.
FiftyFive used AWS CloudWatch, Lambda, and Auto Scaling to align monitoring capacity with transaction demand.
Cloud Security Team
FiftyFive delivered continuous, audit-ready file security without affecting payment performance. The monitoring layer detects changes instantly, maintains transaction availability, and expands with payment demand.
Fail-safe monitoring maintained full payment availability with zero service disruption during continuous operations.
Event-driven AWS detection surfaced unauthorised file changes instantly across payment infrastructure.
Compliance-driven monitoring reduced exposure to regulatory penalties and protected payment operations.
AWS Auto Scaling expanded monitoring capacity with transaction demand while sustaining low latency.
File Integrity Monitoring continuously tracks changes to critical files, configurations, and application code to detect unauthorised modifications and provide real-time alerts and compliance evidence.
Unauthorised file changes can alter transaction handling, affect settlement accuracy, and create regulatory exposure. FIM provides continuous detection and an auditable security trail.
Correctly isolated monitoring adds no measurable transaction latency. A sidecar process runs beside payment services rather than inside the transaction execution path.
A sidecar runs a supporting service separately alongside the main application. For security monitoring, it isolates file inspection from latency-sensitive payment processing.
File changes trigger AWS Lambda detection logic, while CloudWatch handles metrics, logs, and alerts. Auto Scaling adjusts monitoring capacity as activity grows.
Event-driven anomaly detection evaluates modifications when they occur instead of waiting for scheduled scans, delivering faster alerts and using compute only when events happen.
FinTech companies use continuous monitoring, automated alerts, defined escalation workflows, and retained audit logs to demonstrate active security controls during regulatory reviews.
Yes. Fail-safe redundancy ensures monitoring-component failure cannot interrupt the protected service. This solution maintained 100% uptime throughout continuous monitoring.
AWS CloudWatch provides observability and alerting, Lambda executes detection logic on demand, and Auto Scaling expands monitoring capacity with workload demand.
Serverless, event-driven detection and auto-scaling infrastructure expand monitoring capacity as file activity increases, maintaining real-time detection and low latency during peak payment volumes.
Cost depends on infrastructure scale, compliance scope, integration complexity, monitoring coverage, alerting requirements, and the level of redundancy required.
Dedicated FinTech security teams can combine backend engineers, cloud architects, and security specialists to deliver monitoring, compliance controls, AWS infrastructure, and ongoing support.
