MufinPay:
Replacing Manual Ops with
Policy-Driven Delivery
A regulated payments and lending platform on Graviton EC2 moves from person-dependent operations to policy-driven delivery — where protection, assurance, and every release are automated, reversible, and continuously auditable.

AWS Cloud Operations Delivery
Replacing Person-Dependent Operations with Policy-Driven Delivery for a Regulated Payments Platform
About MufinPay
MufinPay is an India-based financial technology provider operating a digital payment processing and lending platform on Graviton-based Amazon EC2. As a regulated enterprise handling sensitive financial data, the business must demonstrate operational discipline and auditability continuously rather than only at audit time.
The Challenge
Person-dependent operations creating unmanaged risk in a regulated payments platform
Person-Dependent Protection
Backup ran from manually maintained scripts with no enforced retention, leaving an unmanaged data-loss risk and no reliable evidence trail for a regulator.
No Continuous Assurance
There was no aggregated view of configuration state, file integrity or known vulnerabilities, so assurance existed only at the point someone looked.
Shared Release Path
Multiple services shared one delivery path with no separation of credentials between environments, so a change intended for testing carried risk to production.
Solutions Provided
Policy-driven protection, continuous assurance, and reversible per-service delivery
Automated Snapshot Lifecycle
Replaced manual backup scripting with a policy-driven snapshot lifecycle using Amazon Data Lifecycle Manager and AWS Backup, with retention enforced by resource tagging so protection applies to new resources automatically.
Continuous Security Observability
Deployed the Wazuh SIEM platform with agents across monitored hosts for configuration assessment, integrity monitoring and vulnerability detection, ingesting AWS CloudTrail from a dedicated access-restricted Amazon S3 bucket, with Amazon GuardDuty for threat detection and PCI DSS and NIST 800-53 modules reporting control state.
Per-Service Delivery Pipelines
Built an independent Bitbucket pipeline for each microservice with separate UAT and Production branches carrying environment-specific credentials, plan review before apply, and automatic publication of pipeline outcomes to the delivery Slack workspace.
Defined Workload Health
Established six monitored indicators with thresholds, severities and response actions across Amazon CloudWatch and a Grafana, Prometheus and Loki stack covering all EC2 instances, infrastructure logs and application logs.
Federated Identity
Implemented AWS IAM Identity Center with permission sets by job function, MFA enforced on all console access, and operator sessions issued through AWS Security Token Service expiring after one hour.
Result Outcome
Protection by policy, always-current assurance, and reversible releases — delivered
Protection by Policy
A new volume is protected on creation and an expired artefact removed without manual action — data protection now scales with the platform automatically.
Assurance Always Current
Configuration, integrity and vulnerability state are assessed continuously and mapped to framework controls, so evidence exists when requested — not only at audit time.
Reversible Releases
Each service releases through its own validated pipeline, and a failed release is reverted by re-applying the previous commit — turning rollback into a routine action.
Console Change Eliminated
The repository is the change record, so what changed, when, by whom and under whose approval is answerable from version control alone.
By Policy
Data Protection
New volumes protected on creation, expired artefacts removed automatically

Before
Backup performed by manually maintained scripts with no enforced retention
No aggregated view of configuration, integrity or vulnerability state
Compliance assurance available only at the point of audit
One delivery path shared across services with no credential separation
Production changeable through the AWS Management Console
After
Snapshot lifecycle enforced by policy and tagging, applying to new resources automatically
SIEM assessing configuration, integrity and vulnerabilities continuously across hosts
Findings mapped to PCI DSS and NIST 800-53 controls and reported on a current basis
Independent per-service pipelines with UAT and Production credential separation
Production changed only through reviewed, reversible pipeline execution
“
The engagement replaced person-dependent operations with policy-driven ones, so operational discipline scales with the platform rather than depending on the diligence of whoever provisions the next instance.
