APIs Security Services

Protect your APIs from business logic flaws, authentication weaknesses, and data exposure.

Simulates real-world attacks against your APIs using provided documentation (Postman/Swagger collections, requests with headers and tokens). Our experts validate authentication, authorization, and business logic to uncover vulnerabilities that automated scanners often miss.

Packages:

  • Small Package: Up to 25 endpoints → ~3 days → €900

  • Medium Package: Up to 50 endpoints → ~5 days → €1,500

  • Large Package: Custom scope (e.g., >50 endpoints, complex GraphQL APIs, microservices) → tailored pricing

All the vulnerabilities from the Automated Vulnerability Scanning plus the following:

  • Weak perimeter defenses, such as misconfigured firewalls or VPNs.

  • Exploitable open ports and services.

  • Credential brute-forcing on exposed services (e.g., SSH, RDP).

  • Insecure file-sharing protocols (SMB, FTP, etc.).

  • Publicly exposed sensitive data or misconfigured DNS settings.

  • Vulnerabilities in web server configurations or hosted applications.

  • Exploitable vulnerabilities in third-party software or systems.

  • Inadequate email security configurations (e.g., SPF, DKIM, DMARC).

All the vulnerabilities from the Automated Vulnerability Scanning and External Infrastructure Penetration Testing plus the following:

  • Sensitive information exposure in file shares or internal applications.

  • Insufficient network segmentation.

  • Insecure protocol usage (e.g., outdated SMB or Telnet).

  • Lateral movement vulnerabilities, such as unprotected admin shares or misconfigured RDP.

  • Weak or outdated encryption on internal communications.

  • Privilege escalation opportunities (e.g., misconfigured services or applications).

  • Insecure Active Directory configurations, such as weak Kerberos policies or mismanaged group permissions.

  • Credential harvesting and reuse attacks (e.g., NTLMv2 relay, pass-the-hash, pass-the-ticket).

Step-by-Step Process

1. Order Service Request


The client orders a "Service Request" by completing the contact form, providing the details of the resources in scope, a brief project description, and contact information.

2. Scope Review & Kick-Off (if applicable)

We review the Service Request and, if necessary, schedule a 30-minute kick-off meeting to discuss the effort estimation, project timeline, and details regarding the in-scope resources. For Black-Box tests, we can proceed directly to the next step.

4. Testing Execution


Our expert team conducts a combination of automated and manual tests, simulating real-world attack scenarios to uncover vulnerabilities and assess security posture.

5. Report Delivery


Upon completion, you'll receive a comprehensive report detailing identified vulnerabilities, their severity levels, and actionable recommendations to enhance your security.

3. Contract and Payment


Once the details are agreed upon, we send the client a contract and invoice. After the contract is signed and payment is received, we begin the testing phase.
