Penetration Testing for SaaS Companies

Manual, expert-led testing that satisfies auditors and protects your business.

Careful Security delivers manual, expert-led penetration testing for mid-market SaaS companies. Our GPEN-certified team tests applications, APIs, networks, and infrastructure using OWASP, PTES, and NIST methodologies. Every engagement includes manual exploitation, business-context risk analysis, and remediation guidance designed to satisfy SOC 2, ISO 27001, and PCI DSS auditor requirements.

Service Types

What We Test

Five testing disciplines covering the full attack surface of a modern SaaS company.

External Network Pentest

We test your public-facing infrastructure from the attacker's perspective. Perimeter servers, exposed services, cloud configurations, and DNS misconfigurations. Every finding is ranked by exploitability and business impact.

Internal Network Pentest

We simulate what happens after a breach. Lateral movement, privilege escalation, credential exposure, and sensitive data access from inside the network.

Web Application Pentest

Deep testing of your SaaS application against the OWASP Top 10. Injection, authentication bypass, business logic flaws, session management, and client-side security.

API Pentest

Automated and manual testing of REST and GraphQL APIs. Authentication weaknesses, data exposure, rate limiting bypasses, and injection vulnerabilities.

Social Engineering Assessment

Simulated phishing campaigns, vishing, and pretexting. We test the human layer — the most exploited vector in modern attacks.
