Industry: Financial services

Finstro is an Australian financial technology company that provides flexible trade credit and payment solutions designed specifically for small and medium-sized enterprises (SMEs). Finstro enables businesses to manage cash flow through business loans, lines of credit, and integrated payment tools. Their proprietary, data-driven credit engine allows for quick approvals, helping suppliers get paid instantly while providing buyers with flexible repayment terms.

Challenge

Previously, Finstro faced several operational pain points in their cloud security approach.

• Limited visibility into vulnerabilities: While AWS native alerting tools were in place, the information they provided was fragmented and required significant manual effort to consolidate and analyse. Security teams spent considerable time piecing together alerts from multiple sources, making it difficult to distinguish between high-priority risks and lower-level findings. As environments multiplied, manual monitoring became increasingly time-consuming.
• Alert prioritisation challenge: Without context or severity weighting, every alert demanded investigation. This created operational overhead that diverted resources from critical issues.

"The challenge wasn't finding vulnerabilities - it was prioritising them. Without context or severity weighting, every alert demanded investigation, creating operational overhead that diverted resources from critical issues." - Barbara Silvestre, Head of IT Operations & Security

Solution‍

To bridge the operational gaps left by native tooling, specifically focusing on contextual triage and automated guidance.

• Automated ownership and accountability: Plerion automated ticket creation and assignment, ensuring vulnerabilities were automatically routed to the teams responsible for remediation. This removed ambiguity around who needed to act and why.‍
• AI-assisted remediation guidance: Plerion's AI security engineer, Pleri provided detailed context at the point of alert: remediation steps, potential impact, alternative approaches, cost impacts, and rollback strategies. This eliminated the manual research overhead that had previously accompanied every security finding.
• Unified multi-environment visibility: Plerion consolidated all AWS environments into a single dashboard. Clear, meaningful dashboards highlighted risks that mattered to the business, enabling faster prioritization and focused remediation efforts.

Key benefits

The operational impact was immediate. The most fundamental change was the removal of uncertainty in security monitoring. Instead of fragmented alert streams, Finstro's team now operates with clear signals and actionable guidance.

1. Clarity and reduced manual overhead: Teams spend less time investigating alerts manually and more time implementing fixes. Resources are focused on areas with the greatest security impact.
2. Improved cross-team communication: The platform became the central interface for security and engineering collaboration. Ownership is clear, remediation guidance is immediate, and there's no ambiguity about why changes need to be implemented.
3. Effective risk prioritisation: Remediation efforts are now prioritized based on genuine business risk rather than alert volume.

"Plerion provided immediate, contextual remediation suggestions...eliminating the manual research step that had previously added overhead to every security finding." - Barbara

Results

Since deploying Plerion, Finstro has achieved meaningful improvements in how it manages cloud security. The team now operates with significantly reduced manual investigation overhead. Alerts are actionable rather than informational, remediation is contextual rather than exploratory, and priority is based on actual business risk.

Looking forward, Finstro is preparing for expansion into the United States and planning for SOC 2 compliance. Plerion's framework assessment capabilities are playing a central role, enabling continuous evaluation of security posture against recognized compliance standards. The platform is providing the foundation the company needs to scale securely.
