Gain a comprehensive view of your third-party landscape. We help you inventory vendors, assess data and system access, and apply a risk-based classification model that aligns with your business priorities.
THIRD-PARTY RISK ASSESSMENTS
YOUR PARTNERS IN VENDOR RISK MANAGEMENT
Reduce Risk. Strengthen Oversight. Protect Your Business.
If your organization is like most, you rely on a complex ecosystem of vendors, partners, and suppliers. But every one of those connections increases your exposure and obligation to mitigate it. A single misconfigured system, shared credential, or unchecked third party can result in a data breach with enterprise-wide consequences.
S3 Security helps you take control of third-party risk by turning uncertainty into clarity and oversight into operational advantages. Our seasoned assessors work alongside your team to evaluate, employ, and enhance vendor risk programs that align with both regulatory expectations and business objectives.
OVERVIEW
ACCOUNTABILITY ACROSS ALL YOUR RELATIONSHIPS
A well-structured third-party risk assessment helps you prioritize resources, close oversight gaps, and stay ahead of emerging threats. It begins with a comprehensive inventory of every third party that has access to your systems, data or operations. Each vendor is classified by risk level, and then evaluated using a consistent set of business-aligned criteria, including:
- Security controls and certifications (e.g., ISO 27001, SOC 2)
- Regulatory compliance (PCI DSS, HIPAA, etc.)
- Financial stability and operational maturity
- History of breaches or known vulnerabilities
- Record of identifying/patching vulnerabilities in a timely manner
- Data processing and storage practices
This foundational view gives your team the insight needed to act decisively by prioritizing high-risk vendors, streamlining remediation efforts, and reducing overall exposure.
Our experienced team then leads yours through a structured process for addressing both immediate gaps and long-term exposure. We align your risk management strategies with your business priorities to support smarter decision making. We also provide critical guidance on road map development, forecasting, and executive reporting.

FIVE PILLARS OF THIRD-PARTY RISK MANAGEMENT
A strong vendor risk management program requires more than a one-time assessment or a basic checklist. Third-party relationships are dynamic and complex, and your risk exposure evolves as your business grows.
S3 Security takes a structured, strategic approach to third-party risk management. Our methodology focuses on five core capabilities that help your team make informed decisions, reduce risk exposure, and strengthen vendor oversight. Each area supports a more resilient and compliant program that scales with your business needs.
