How is this different from a Nessus or Burp scan?

Scanners are part of our toolkit, not the product. A typical engagement spends 20-30% of the time on tooling and the rest on manual exploitation, business-logic abuse, and chaining findings. You pay us for the judgment, not the scan output.

Do you exploit findings or just report them?

Within the rules of engagement you approve. We'll demonstrate impact on staging or a contained production path whenever possible. For production systems where exploitation is off-limits, we document the exploit chain and reproduction steps so your team can verify it in a safe environment.

How long does an engagement take?

Most web or API engagements run 1-3 weeks of active testing, followed by 3-5 business days for reporting. Larger scopes (multi-app, infrastructure + cloud) run 3-6 weeks. We scope every engagement in writing before kickoff so there are no surprises.

Can you test production systems?

Yes, with explicit written rules of engagement, change-window coordination, and a rollback plan. Most clients prefer staging for first-time engagements and production for retest passes.

Penetration Testing

Manual, senior-led exploitation for internet-reachable web applications and REST/GraphQL APIs. First engagement: we find a high-severity vulnerability or you don’t pay.

What we put our name behind

Senior-led manual exploitation, reproducible chains

Every CAASLABS pentest is executed end-to-end by a credentialed senior practitioner (OSCP+ and above) with a manual exploitation mindset — scanners are used where they earn their keep and stop there. You get reproducible proof-of-concept chains, CVSS v3.1 scoring verified by hand, and a report written by the person who found the bug. No offshore review layers, no template PDFs, no scan-and-forward.

Overview

Manual, senior-led penetration testing for internet-reachable web applications and REST/GraphQL APIs. Most "penetration tests" on the market are automated vulnerability scans with a human rubber-stamp on top — we don't run them. Every CAASLABS pentest is executed by a credentialed senior practitioner with a manual exploitation mindset, using scanners where they earn their keep and stopping there.

We test the way a real attacker would: chain low-severity findings into business-impact outcomes, abuse auth logic, escalate privileges laterally across services, and exfiltrate data through the paths your blue team actually needs to watch. Mobile, network perimeter, and infrastructure engagements are available on request and covered elsewhere on this site — we'll point you to the right scope on the diagnostic call.

What's included

Every engagement is senior-led and scoped in writing before kickoff.

Web application testing

OWASP Top 10 coverage plus business-logic testing that tools miss — auth bypasses, IDOR, SSRF, workflow manipulation, and multi-step exploit chains.

API testing

REST, GraphQL, and gRPC. Authz enforcement across every endpoint, rate-limit bypass, parameter pollution, mass-assignment, and broken object-level authorization (OWASP API Top 10).

Mobile application testing

iOS and Android. Static analysis of the binary, runtime instrumentation (Frida), insecure storage, certificate pinning bypass, deep-link abuse, and backend API coverage.

Network & infrastructure testing

External perimeter, internal pivot testing, Active Directory abuse, misconfigurations, exposed services, and credential-stuffing resilience.

Cloud infrastructure testing

AWS, Azure, and GCP misconfigurations, over-permissive IAM, exposed metadata endpoints, cross-tenant data access, and storage bucket exposure.

What you get

Written scope and rules-of-engagement document (signed before kickoff)
Daily progress updates during the engagement window
Technical report with reproduction steps, CVSS scores, and remediation guidance
Executive summary for leadership and board reporting
Verification retest of every critical and high finding, completed within 60 days of report delivery (request by day 45)

Ideal for

SaaS companies preparing for SOC 2, ISO 27001, or enterprise procurement
Fintech, healthtech, and regulated teams needing evidence for auditors
Engineering teams who want a real adversarial review before a major launch
Anyone who has received a "pentest" report that was clearly automated
