SaaS penetration testing

Security testing built for modern SaaS companies.

SaaS companies face a unique set of risks. Rapid releases, complex access models, multi-tenant architectures, and enterprise security reviews all put pressure on your team. Packet33 helps SaaS organizations identify real weaknesses before they affect customers or impact deals.

Transparent, scope-based pricing. No surprises after kickoff.

Why it matters

Security expectations for SaaS have never been higher.

Investors, enterprise buyers, and compliance frameworks often require penetration testing as part of annual reviews or vendor assessments. Penetration testing for SaaS platforms goes deeper than a generic scan. It focuses on how your application works, how data flows between tenants, and how your APIs behave under attack.

Common drivers

SOC 2 audits and readiness
Enterprise procurement reviews
Customer security questionnaires
Vendor risk assessments
New feature launches or architecture changes

Why teams trust our reports

Senior practitioners. Proof before you commit.

Every engagement is tested by senior, certified practitioners with over a decade of hands-on experience each, never handed off to junior staff or run purely through automated tooling.

Typical SaaS web and API engagement

1 to 2 weeks from kickoff to report delivery

Pricing depends on the number of applications, environments, and APIs in scope, along with authentication complexity. Most single-application SaaS engagements for early-stage teams fall toward the lower half of this range.

Often paired together

Bundled with Audit Readiness.

If you are preparing for an upcoming SOC 2 audit, pairing a penetration test with our Audit Readiness service is the most efficient path to being fully prepared. We scope both engagements together so nothing falls through the cracks.

Frequently asked questions

Common questions before getting started.

SOC 2 does not explicitly mandate penetration testing, but many auditors and customers expect it as part of a strong security program. An independent test is often used to demonstrate that controls are working in practice.

A typical SaaS penetration test covers authentication, session handling, authorization, tenant isolation, APIs, and business logic paths that affect how users and data interact.

Most SaaS penetration tests take one to two weeks, depending on the size of the application, the number of environments, and whether APIs or admin portals are in scope.

Most SaaS web and API engagements run $8,000 to $30,000, depending on the number of applications, environments, and APIs in scope, along with authentication complexity. Early-stage teams with a single application typically fall toward the lower half of that range.

Common trigger points include preparing for SOC 2 or ISO 27001, closing larger customers, launching major features, or after significant changes to your architecture. It is recommended to conduct a pentest every 12 months.
