SaaS Risk Assessment: Key Steps to Secure SaaS Applications

Conducting a software‑as‑a‑service (SaaS) risk assessment is pretty straightforward when you have one or two SaaS apps. However, once you expand your mix of SaaS solutions, assessing your risk of data breaches and protecting your business from unwanted intrusions can get exponentially more complicated quickly.

Believe it or not, organizations use an average of more than 100 SaaS applications, many of which they have no visibility into—a.k.a. shadow IT—as employees adopt low‑ or no‑cost SaaS solutions without triggering IT, finance, and legal approval.

This mix of the unknown plus the potential risk of exposure—financially, legally, and operationally—has turned into many sleepless nights for leadership teams.

Alleviating those concerns is where SaaS risk assessments come into play. They can help companies identify and mitigate threats tied to SaaS solutions using a combination of technologies, training, and other tools to protect sensitive data and their businesses.

What is SaaS Risk Assessment?

A SaaS risk assessment evaluates and identifies potential dangers of data breaches and other harms based on an organization’s use of SaaS applications. These risks may include security vulnerabilities, operational hazards, and risks related to non‑compliance with laws and regulations.

Companies in highly regulated industries have explicit requirements to adhere to, but all businesses face internal and external threats from bad actors or human mistakes. Regular risk assessments of both vendors and internal practices can mitigate your exposure. This process is critical not only for maintaining compliance but also for ensuring that the overall risk profile of your SaaS environment is continuously monitored and updated.

By incorporating automated monitoring and periodic manual audits, organizations can achieve a deeper understanding of their security posture. As detailed in SaaS Security Concerns, Risks, Challenges and Effective Solutions, leveraging multiple assessment techniques is essential for a holistic view of SaaS risk.

Key Components of a SaaS Risk Assessment

The foundation of a thorough SaaS risk assessment lies in identifying and addressing several critical components. These components ensure that all aspects of potential exposure are systematically examined and mitigated.

Effective risk assessments consider not only technological vulnerabilities but also procedural and human factors. By evaluating the security measures implemented by SaaS providers and the internal practices of an organization, companies can develop a comprehensive view of their risk landscape.

1. Confidentiality, Integrity, and Availability (CIA)

The CIA triad represents the three pillars of information security. It focuses on:

• Confidentiality: Ensuring that private data remains inaccessible to unauthorized users.
• Integrity: Guaranteeing that data remains accurate, complete, and unaltered during storage or transmission.
• Availability: Ensuring that data and applications are accessible to authorized users when needed.

This balanced approach helps protect against unauthorized access while providing the necessary information flow to support business operations. For further details on maintaining a robust security framework, refer to Choosing the Right SaaS Security Tools.

2. Data Security

Data security is a critical focus in any SaaS risk assessment. Key measures include:

• Encryption: Encrypting data both at rest and in transit ensures that even if data is intercepted, it remains unreadable to unauthorized parties.
• Identity and Access Controls: Verifying user identities and enforcing strict permissions helps prevent unauthorized access to sensitive information.
• Breach Prevention: Implementing comprehensive training, security policies, and monitoring tools to detect and prevent potential breaches before they occur.

These measures not only protect against external threats but also help guard against internal errors and misconfigurations. To understand more about the importance of data security, see SaaS Data Ownership and Portability: Don’t Be a Vendor Hostage.

3. Service Level Agreements (SLA)

SaaS providers detail their security-related processes and commitments in several legal documents, including Terms & Conditions, End‑User License Agreements, and especially Service Level Agreements (SLAs). SLAs are critical for risk assessments because they specify:

• Uptime/Downtime: Guarantees regarding the overall availability of the application.
• Security Incident Reporting: Procedures for notifying users about security issues or breaches.
• Response Times: Metrics for how quickly support issues and security patches are addressed.
• Data Backup and Recovery: Strategies to restore data and maintain continuity in case of an incident.

Reviewing these agreements is vital to understand how a provider manages risk and ensures the reliability of their services. For additional insights, you might explore SaaS Security Monitoring.

Steps to Conduct a Comprehensive SaaS Risk Assessment

Conducting a detailed risk assessment involves a systematic approach to identifying vulnerabilities and developing strategies for mitigation. This process is crucial for protecting sensitive data and ensuring that potential threats are addressed before they lead to significant breaches.

Key steps include:

• Identify Critical Data: Determine which types of information within your organization are sensitive and at risk. Understand where this data is stored and how it is used.
• Determine SaaS Usage: Inventory the SaaS applications currently used by your employees. Be aware of shadow IT, as unapproved applications can introduce unforeseen risks.
• Evaluate Vendor Security: Assess whether your SaaS providers comply with your organization’s security standards and regulatory requirements. Look for certifications and robust security policies.
• Identify Risks: Pinpoint vulnerabilities such as misconfigurations, weak access controls, and compliance gaps—especially those that may arise from third-party integrations.
• Analyze Threats: Evaluate the likelihood and impact of each identified risk, considering factors like external threats, internal misconfigurations, and integration issues.
• Document Findings: Compile a comprehensive report that summarizes vulnerabilities and provides actionable recommendations for risk mitigation.
• Take Action: Implement a mitigation plan to address critical issues, such as applying patches, enhancing security protocols, and improving training programs.

This methodical process not only identifies current vulnerabilities but also helps create a roadmap for continuous security improvement across all SaaS applications.

Case Study: Lessons Learned from Equifax’s Data Breach

Let’s take a look at one company’s costly data security mistake.

• Company: Equifax
• Penalty: $575 million Federal Trade Commission settlement, plus loss of credibility and reputation in the market.
• What Happened: Approximately 150 million people’s personal and financial information was exposed due to an unpatched Apache Struts framework in one of its databases. It took Equifax 76 days to recognize the breach—months after the security issue had first been identified. Additionally, the company failed to inform the public for weeks after discovering the breach. (Sources: CSO Online and Wikipedia)
• Lessons Learned: Although Equifax has not disclosed every detail of its response, key takeaways include the importance of regular risk assessments, open communication about security threats, prompt vulnerability management, and proactive breach disclosure. It is crucial to:
• Perform regular risk assessments to identify vulnerabilities early.
• Establish open communication both internally and externally regarding current and potential threats.
• Ensure your team has the necessary resources and a clear plan to prioritize and address vulnerabilities promptly.
• Disclose breaches proactively to build trust with employees, customers, partners, vendors, and regulatory agencies.

As stated by Federal Trade Commission Chairman Joe Simons, "Companies that profit from personal information have an extra responsibility to protect and secure that data." Similarly, Consumer Financial Protection Bureau Director Kathleen L. Kraninger emphasized that evolving cyber security threats demand rigorous protection of personal information.
