In the financial services sector, security and compliance are non-negotiable. With sensitive customer data, transaction records, and proprietary financial information at stake, the adoption of SaaS (Software as a Service) applications comes with significant security challenges. Financial institutions are increasingly using SaaS tools to improve operational efficiency, but this also opens the door to potential security risks if these applications aren’t properly managed and monitored.
How can financial institutions leverage the benefits of SaaS while maintaining airtight security and compliance with regulations like PCI DSS, SOX, and GDPR? Let’s explore five essential steps to securing SaaS environments in the financial services industry.
Step 1: Create a Comprehensive Security Map
In the financial sector, the rise of “Shadow IT” — where employees use unauthorized SaaS applications — can expose your organization to unmitigated risks. These tools may lack the necessary controls to protect sensitive financial data or comply with industry regulations, making them a potential liability.
Creating a security map starts with identifying all SaaS applications in use across your institution. Use SaaS discovery tools to find out which apps are being used — whether approved or not — and assess the level of risk they introduce. Once you have a comprehensive view of your SaaS landscape, you can evaluate which applications need to be brought into compliance or removed altogether. This step is critical in preventing unauthorized access to sensitive financial data.
Step 2: Clarify Responsibility and Enforce Access Controls
SaaS security in financial services is a shared responsibility between your organization, your IT and compliance teams, and the SaaS vendors you work with. However, ambiguity in roles can lead to vulnerabilities, especially when dealing with financial transactions, customer data, and compliance obligations.
Clearly define who is responsible for what. IT should enforce strong access control mechanisms, such as Single Sign-On (SSO) and Multi-Factor Authentication (MFA), while compliance teams ensure that SaaS vendors meet industry regulations like PCI DSS. Additionally, employees should be trained on maintaining strong passwords and securely handling financial data. Proper role-based access control (RBAC) must also be implemented to restrict access to sensitive information, ensuring that only authorized personnel can access critical data.
Step 3: Ensure Compliance with Industry Regulations
The financial sector operates under strict regulatory frameworks, such as PCI DSS (for handling payment information), SOX (Sarbanes-Oxley Act for financial reporting), and GDPR (for protecting customer data). Every SaaS application used by your organization must adhere to these regulations to avoid costly fines, legal repercussions, and reputational damage.
Before onboarding any SaaS tool, conduct a thorough review to ensure that it complies with your organization’s regulatory requirements. This includes verifying that the application encrypts data both at rest and in transit, supports audit logs, and meets data residency regulations. SaaS vendors should also provide assurances that they maintain rigorous security controls to protect your data. Regularly review your SaaS portfolio to ensure continued compliance as regulations evolve and new security risks emerge.
Step 4: Continuously Monitor and Conduct Security Assessments
In the financial services industry, the risk landscape is dynamic, and cyber threats are becoming more sophisticated. Continuous monitoring and regular security assessments of your SaaS applications are vital to ensuring that your data remains secure.
Implement tools that provide real-time monitoring of your SaaS applications, keeping an eye out for changes in risk scores, suspicious activity, and potential security breaches. Monitor for compliance with regulatory requirements, such as PCI DSS or GDPR, and ensure that no unauthorized applications are handling sensitive financial information. Conduct regular security audits and vulnerability assessments to identify weak points in your SaaS environment before they can be exploited.
Step 5: Use SaaS Security Posture Management (SSPM) Tools
Misconfigurations are one of the leading causes of data breaches, particularly in highly regulated sectors like financial services. With the complexity of modern SaaS environments, even a small misconfiguration can lead to significant security risks, such as unauthorized access to customer financial data or failure to comply with regulations.
SaaS Security Posture Management (SSPM) tools help financial institutions continuously monitor and manage the security configurations of their SaaS applications. These tools can detect misconfigurations, over-permissioned accounts, and potential vulnerabilities that may expose sensitive data. SSPM ensures that your SaaS environment remains in alignment with your organization’s security policies and industry compliance standards.
Top 5 SaaS Security Solutions for Financial Services
Here’s an overview of the top SaaS security solutions specifically suited to the financial services industry, along with their pros and cons.
Pros:Waldo Security provides financial institutions with a powerful SaaS discovery and governance solution, helping map all SaaS applications in use to ensure compliance with security frameworks like PCI DSS and SOX. It also assists in identifying gaps in security controls and ensuring that authentication protocols like SSO and MFA are in place.
Cons:While Waldo excels in discovery and governance, it lacks comprehensive posture management capabilities. For financial institutions that require real-time monitoring of SaaS configurations, additional tools may be needed to supplement Waldo’s strengths.
2. Zscaler
Pros:Zscaler is well-regarded for its network security capabilities, helping financial organizations control access to SaaS applications by monitoring and managing network traffic. Zscaler is particularly effective at preventing unapproved SaaS tools from being used within the organization, thereby reducing the risk of data exposure.
Cons:Although Zscaler is effective at the network level, it doesn’t offer deep visibility into specific SaaS applications, such as who is accessing them or how they are configured. For financial institutions that require granular SaaS application oversight, additional solutions may be necessary to provide full visibility into user activity and app settings.
3. Varonis
Pros:Varonis specializes in protecting sensitive data, making it an ideal choice for financial institutions managing large amounts of proprietary and customer data. It provides data classification, monitoring, and analytics to prevent unauthorized access to sensitive information. Varonis also includes posture management features, helping financial organizations monitor and adjust security configurations for key SaaS applications like Office 365.
Cons:Varonis’s posture management is limited to a select few applications, such as Office 365. For financial institutions that rely on a broader SaaS stack, additional tools may be required to ensure comprehensive posture management across all applications.
