The financial sector relies on SaaS applications, APIs, and third-party integrations for efficiency and innovation. But these same connections create a growing attack surface that traditional security tools fail to monitor. Third-party breaches, API abuse, and non-human identity risks continue to expose sensitive financial data, making real-time detection and response critical for security teams.
That’s why Vorlon is proud to sponsor the FS-ISAC 2025 Americas Spring Summit and the Morning Networking Break on March 10. FS-ISAC brings together financial security professionals to collaborate on securing an evolving threat landscape, and we’re excited to share our expertise on securing the SaaS ecosystem in today’s high-risk environment.
The hidden security risks in financial SaaS ecosystems
Financial institutions depend on hundreds of interconnected SaaS applications that exchange data through APIs, OAuth tokens, and machine-to-machine interactions. Attackers don’t just target a single misconfigured app—they exploit gaps between vendors, abuse excessive permissions, and move laterally across integrated services. These blind spots leave financial organizations vulnerable to:
- API and OAuth token misuse, allowing threat actors to infiltrate systems without triggering traditional security alerts.
- SaaS misconfigurations and excessive third-party permissions, leading to unintended data exposure and compliance risks.
- Lack of real-time detection and response, forcing security teams to react to breaches instead of proactively stopping them.
Traditional security tools like SIEMs, SSPM, and API security solutions fall short because they focus on individual applications rather than the full SaaS ecosystem. Financial institutions need continuous monitoring, ecosystem-wide visibility, and automated remediation to combat today’s threats.
How Vorlon helps financial services secure their SaaS ecosystem
Financial security leaders are recognizing the need for a holistic approach to SaaS security—one that detects and responds to threats in real-time across integrated applications. One example is Splitit, a global payment solution provider, which turned to Vorlon to tackle SaaS-to-SaaS security challenges.
With Vorlon’s SaaS Ecosystem Security Platform, Splitit achieved:
- 93% reduction in the time to detect and respond to third-party security incidents.
- Visibility into API data flows they didn’t know existed.
- Elimination of hours of manual compliance work, automating PCI DSS and SOC 2 audit evidence collection.
- Stronger security posture through continuous control validation across their SaaS environment.
"We started seeing integrations sharing data that we never knew existed."
— Ran Landau, CTO, Splitit
Vorlon provides financial security teams with:
- Near real-time detection and response across the entire SaaS ecosystem.
- Continuous monitoring of non-human identities, API activity, and sensitive data flows.
- Automated risk assessment and remediation that integrates with SIEM, SOAR, and ITSM platforms.
Let’s connect at FS-ISAC 2025
Vorlon’s Eric Schlesener will be at FS-ISAC 2025 Americas Spring Summit to meet with financial security leaders and discuss:
- The role of SaaS ecosystem security in mitigating third-party risks.
- How to implement real-time detection and response for API-based threats.
- Best practices for securing OAuth tokens, non-human identities, and SaaS integrations.
FS-ISAC plays a crucial role in strengthening financial security by facilitating intelligence sharing and collaboration across the industry.
