Example report structure and finding format
Security risk now reaches startups through vendors, packages, identity, and cloud access.
Recent public incidents show the same pattern: attackers look for inherited trust before targeting the product directly. A useful pentest validates what an attacker could reach, which data is exposed, and how quickly the team can close the path.
Review your exposureRecent incidents in common tools
Unauthorized access reached internal systems at a major app host.
Axios npm versions shipped malware through normal installs.
AI-assisted cyber operations are no longer theoretical.
AI-built phishing pages can imitate real login flows in seconds.
A trusted browser script became a web-wide supply-chain risk.
Pentests for startups preparing to launch, fundraise, or pass security review.
We test the app, API, cloud, and network paths that could block a launch, slow a deal, or fail a vendor review.
Web application testing
Authentication, authorization, session handling, data exposure, file upload, business logic, and OWASP Top 10 coverage.
API security testing
REST, GraphQL, and gRPC testing for IDOR, broken object authorization, mass assignment, injection, and rate-limit bypass.
Cloud and infrastructure
Cloud IAM, external exposure, storage controls, Kubernetes, perimeter services, and practical privilege escalation paths.
Network penetration testing
External and internal network assessment covering perimeter exposure, Active Directory risk, lateral movement, and segmentation.
A controlled workflow from authorization to retest.
The work is structured so engineering teams, leadership, and auditors can understand what was tested, what was found, and how to fix it.
Scope
Confirm targets, roles, environments, exclusions, rate limits, test windows, and escalation contacts.
Test
Combine focused automation with manual exploitation, authorization review, and sensitive workflow testing.
Report
Deliver validated findings with evidence, reproduction steps, impact, severity rationale, and fix guidance.
Retest
Re-run the original exploit path after remediation and document the final status for evidence requests.
Choose the level of access that fits your stage.
Startups usually need black-box external coverage or grey-box testing with real user roles. White-box review is available when a sensitive workflow needs deeper validation.
Black box
External attacker perspective with no internal documentation or credentials beyond agreed scope.
Grey box
Authenticated testing with test users, role coverage, and enough context to go deeper faster.
White box
Source-assisted review with architecture notes, admin access, and targeted validation of sensitive paths.
The deliverable is a technical penetration-test report.
The final report is written to help engineers reproduce, prioritize, fix, and verify closure. It is also structured for vendor reviews and audit evidence requests, including SOC 2 and ISO/IEC 27001.

Findings & Research
Cross-tenant export exposed tenant records
Authorization checks failed when export jobs were requested through the API.
MFA bypass on invited admin flow
A role transition path allowed privileged access before the second factor was enforced.
Webhook retry leaked internal error detail
Verbose responses exposed service names and queue identifiers useful for chaining.
