Web applications
Broken access control between user roles, insecure direct object references on account endpoints, weak session invalidation after password change, and business logic that trusts client-side price or quantity values.

Recurring findings
Weaknesses we see again and again.
Patterns drawn from hands-on testing across web, API, mobile, cloud and AI systems.
APIs
Undocumented or legacy endpoints left routable, object-level authorization enforced in the UI but not the API, mass assignment on update calls, and rate limiting applied per page instead of per token.
Mobile applications
Secrets and API keys shipped inside the build, sensitive data cached in local storage or logs, missing certificate pinning, and server-side checks skipped because the app already validated them.
Cloud environments
Over-permissive IAM roles reused across services, storage buckets exposed through misconfigured policies, unrestricted management ports, and disabled or unmonitored audit logging.
AI/ML and LLM features
Prompt injection through untrusted content, tool and function calls executed without authorization checks, sensitive context leaking into model responses, and no output validation before downstream use.
Why scanners miss these
Automated tools match known signatures. Authorization flaws, chained logic abuse and multi-step workflows require a tester who understands what your application is supposed to allow.
Readiness checklist
Get more out of every assessment.
Six things to have ready before testing starts. Each one converts setup time into testing depth.
Define the scope precisely
List every domain, subdomain, API base URL, mobile build and cloud account in scope, and note anything explicitly out of scope.
Provide test accounts per role
At least two accounts for every privilege level. Role-to-role testing is how access control flaws surface.
Share documentation early
API collections, architecture notes and known issues shorten discovery and put testing time into deeper areas.
Use a non-production environment
A staging environment with production-like data and configuration keeps destructive test cases safe.
Relax blocking controls for testers
Allowlist our source IPs on WAF and rate limiters, otherwise the assessment measures the WAF rather than the application.
Agree on communication
A single point of contact and an escalation path so critical findings reach you the same day they are found.
Reporting standard
What you receive after testing.
A report is only useful if a developer can act on it without asking follow-up questions.
Executive summary
A short, non-technical view of risk posture, the most serious issues and what they mean for the business.
Reproducible finding detail
Every finding includes affected endpoints, exact steps, request/response evidence and screenshots so your team can confirm it.
Risk rating with context
Severity based on real exploitability and impact in your environment, not just a raw scanner score.
Actionable remediation
Specific fix guidance for developers, plus the underlying pattern to correct so the issue does not reappear elsewhere.
Retest confirmation
After your fixes, we retest the reported issues and document what is resolved and what remains open.
