Frequently Asked Questions

We’ve pulled together the top questions companies ask when evaluating network penetration testing. From securing APIs to meeting SOC 2 compliance, here’s what matters most.

Do you test multi-tenant SaaS applications?

Yes. We specialize in testing multi-tenant SaaS platforms to ensure customer data is properly isolated. Our team looks for access control flaws, misconfigurations, and logic issues that could allow one tenant to see another’s data.

Can you test our APIs and integrations?

Absolutely. API security is critical for SaaS companies. We test REST, GraphQL, and other APIs for issues like authentication flaws, injection vulnerabilities, and insecure data exposure.

How do you handle testing without disrupting uptime for our SaaS platform?

We coordinate closely with your engineering team to plan scope and timing. Our testing methods are designed to be non-disruptive, so your customers experience no downtime or performance issues.

Can your penetration testing support SOC 2 or ISO 27001 compliance for SaaS providers?

Yes. Our reports are audit-ready and can be mapped to frameworks such as SOC 2, ISO 27001, and GDPR. This helps you demonstrate security maturity to auditors, customers, and regulators.

What types of vulnerabilities do you typically find in SaaS environments?

Common issues include insecure authentication flows, misconfigured APIs, weak access controls, insecure CI/CD pipelines, and cloud misconfigurations.

What is cybersecurity penetration testing?

Cybersecurity penetration testing simulates real-world attacks to identify vulnerabilities in your systems, applications, and networks. It helps SaaS companies strengthen defenses, reduce risk, and meet compliance requirements.

What is the difference between a vulnerability scan and a penetration test?

A vulnerability scan is automated and flags potential weaknesses. A penetration test is human-led and actively exploits those weaknesses to show the real business risk.

What is web application penetration testing?

Web application penetration testing simulates cyberattacks on websites and SaaS apps to find vulnerabilities like SQL injection, cross-site scripting (XSS), and authentication flaws that could expose sensitive data.

What does a cloud penetration test cover?

A cloud penetration test assesses environments like AWS, Azure, and Google Cloud. We identify misconfigured IAM policies, insecure storage buckets, and weak network security rules that could lead to a breach.

What can I expect from a Red Sentry penetration test report?

Our reports are clear and actionable. They include prioritized vulnerabilities, remediation guidance, and a free retest to confirm fixes. Reports are structured to be audit-ready for compliance frameworks like SOC 2.

How is pricing determined for Red Sentry’s penetration testing services?

Pricing depends on the size and complexity of your SaaS environment. We offer transparent, customized pricing with no hidden fees, determined during an initial scoping call.
