Protect the APIs That Connect Your Business

Identify weaknesses that could expose sensitive data, disrupt critical integrations, or allow unauthorized actions before they become business incidents.

Understand the Risk Behind Your APIs

API Penetration Testing is an authorized security assessment that determines whether weaknesses in an API could expose sensitive data, enable unauthorized actions, or compromise connected applications and integrations.

APIs connect applications, customers, partners, and internal systems to critical business information and operations. When their security controls fail, attackers may gain access to sensitive data, misuse trusted connections, or perform actions they were never intended to complete.

Teisoft provides expert-led API Penetration Testing for web and mobile application backends, business integrations, partner connections, and other supported APIs. Each assessment gives technical teams clear evidence, prioritized findings, and practical guidance for reducing the identified risk.

Built to Protect Data, Access, and Business Operations

Protect Sensitive Information

Identify weaknesses that could expose customer, employee, partner, or confidential business data.

Strengthen Access Controls

Verify that users, applications, and connected systems can access only the information and functions assigned to them.

Secure Critical Operations

Determine whether API functionality could be misused to alter records, bypass approvals, or perform unauthorized business actions.

Reduce Integration Risk

Evaluate the security of connections between applications, mobile services, partners, and internal systems.

Built for APIs Across Your Digital Environment

Web and Mobile Application APIs

Evaluate the services that connect customer-facing applications and mobile experiences to business data and functionality.

Partner and Business Integrations

Assess the connections used to exchange information and perform operations between customers, vendors, and trusted systems.

Internal and Administrative APIs

Review the services that support internal applications, administrative functions, automation, and operational workflows.

Modern and Legacy API Technologies

Test supported REST, GraphQL, SOAP, webhook, and service-to-service implementations according to the authorized scope.

Go Beyond Automated API Scanning

Automated Tools Miss Business Context

Automated tools can identify technical issues, but they cannot always understand how users, permissions, data, and business processes are supposed to interact.

Manual Testing Reveals Meaningful Risk

Manual testing evaluates the API within its actual business context, helping distinguish theoretical weaknesses from risks that could meaningfully affect your organization.

Clear Evidence Guides Remediation

The result is a clearer understanding of what could be exposed, which operations could be misused, and what your technical team should address first.
