Your application security testingshould find what scanners miss.
CyberXhunt tests web applications, APIs, and mobile apps with manual-led expertise backed by real vulnerability research — including documented CVEs, Linux kernel contributions, and public security recognition. We deliver findings your engineering team can act on, not scanner noise to investigate.
We review every request and respond with the next scoping step — no automated follow-up, no sales handoff.
Verified Credentials
Research-Backed Security Delivery
CyberXhunt's testing is grounded in active vulnerability research — documented CVE discoveries, Linux kernel contributions, and platform-level security recognition. That research depth translates directly into findings your engineering team can act on.
Public research and recognized findings are proof of technical depth, brought directly into client delivery: clearer root-cause analysis, stronger scoping decisions, and remediation guidance that helps your team move confidently.

Service Portfolio
Security testing across the surfaces your product depends on.
CyberXhunt scopes web, API, mobile, code review, and DAST validation work around the actual surfaces your product team needs confidence in.
No overselling adjacent services. No scope inflation. If the work does not fit your current risk question, we say so.
Application Security Testing
Manual-led testing with targeted automation for product teams that need validated findings, practical remediation guidance, and a clear scoping path.
Web Applications
SaaS platforms, dashboards, and browser-based systems
API & Backend Systems
REST, GraphQL, and service-to-service architectures
Mobile Applications
iOS/Android apps, storage, transport, and backend interaction
Web Application Security Testing
Manual-led web application testing for real exploitability, business logic abuse, authenticated attack paths, and release-critical workflows.
- Authenticated and unauthenticated workflows across the agreed target surface
- Business logic, authorization, session handling, and high-risk user actions
- OWASP Top 10 coverage with human validation of exploitability
- Tool-assisted coverage alongside manual testing — every finding reviewed and validated by a person before delivery
Credibility anchor: Public research and CVE work strengthen depth on complex edge cases
See Service ScopeAPI Security Testing
API security testing focused on authorization, object exposure, business abuse, data handling, and backend trust boundaries.
- Authentication and authorization testing including BOLA and BFLA paths
- Input handling, rate controls, data exposure, and abuse-case coverage
- Request-level testing across REST, GraphQL, and scoped backend flows
- Manual testing supported by automation for endpoint mapping, replay, and evidence capture
Credibility anchor: Research-led testing posture for logic-heavy and high-trust systems
See Service ScopeMobile Application Security Testing
Mobile app testing for iOS and Android covering client protections, storage, transport, session handling, and backend interaction risk.
- Client-side storage, secrets handling, transport, and session behavior
- Android or iOS app flows across the scoped build or release candidate
- Backend interaction abuse through mobile workflows
- Manual testing supported by automation for traffic inspection, workflow replay, and coverage
Credibility anchor: Research depth useful for edge cases beyond standard mobile checklists
See Service ScopeSecure Code Review
We read the code an attacker would read. Source review identifies logic flaws and exploitable patterns that no automated scanner finds, then we validate which scanner findings are real and worth fixing.
- Manual review of critical code paths and trust boundaries
- SAST result validation, deduplication, and priority shaping
- Targeted exploit reasoning and code-level root cause analysis
- Prioritized fix list that separates signal from noise with developer-ready remediation context
Credibility anchor: Research-led analysis useful for edge cases scanners flag poorly
See Service ScopeDAST Validation & Scanner Triage
Confirm which scanner findings are real. Stop spending engineering time chasing false positives — we validate live, confirm exploitability, and separate real risk from scanner noise.
- DAST result validation and exploit confirmation where relevant
- Attack surface verification across selected web and API routes
- Authenticated dynamic testing where access is available
- Human confirmation of findings with prioritization guidance for engineering and release teams
Credibility anchor: Manual review reduces false confidence from automation-only workflows
See Service ScopeWhy It Matters
Testing backed by actual research, not tool outputs.
Most security testing firms run a suite of tools and produce a report from the output. We approach every engagement the way a researcher approaches a target: with judgment about what matters, what is exploitable, and what the finding actually means for your application.
Validated exploitability
We confirm every finding manually before it enters your report. If we cannot demonstrate the exploit, it does not ship as a critical finding.
Developer-ready outputs
Reports are structured for the engineers who will fix the issues: reproduction steps, root cause, fix guidance, and CVSS context — not vague descriptions requiring a follow-up call to understand.
Research-grounded judgment
Our methodology comes from active vulnerability research in production systems. When we identify a risk, it is because we understand how attackers find it — not because a scanner assigned it a high CVSS score.

When Teams Work With Us
Four situations where CyberXhunt fits.
Before you ship a major feature
Your team is launching a new surface or significant feature and needs to validate security before it goes live. We scope a targeted assessment, test the attack paths that matter, and deliver findings in time to fix before launch.
Before a customer or enterprise security review
A prospect is asking for a pentest report as part of due diligence. You need credible, well-documented findings — not a checkbox report. We deliver an audit-ready technical report and executive summary built for procurement reviewers.
When your DAST scanner is producing noise
Your team runs automated scanning and produces findings you cannot confidently prioritize. We validate which issues are real, which are false positives, and which should be fixed first — before your engineering team wastes cycles chasing non-issues.
When you need your first security assessment
You have never had a professional security assessment. You need to understand your actual risk profile — not purchase a certification. We scope the work to your real attack surface and give your team a clear starting point.
Target surface (web, API, mobile, code) and black-box or grey-box access confirmed before work begins.
Applied testing against the scoped surface. Every significant finding validated manually — exploit evidence captured before delivery.
Technical report with reproducible findings, executive summary, remediation guidance, and retest as scoped.
Research-Backed Findings
How Testing Works
CyberXhunt keeps the buying path simple while making the delivery path precise. Scope is defined by target surface and access level, evidence is validated manually, and remediation support is tied to the actual findings.
Scope by Surface and Access Model
Define whether the work is web, API, mobile, code review, or research-heavy, plus black-box or grey-box access.
Validate Evidence, Not Scanner Noise
Apply the right testing techniques for the agreed scope. Every finding is validated manually — if we cannot prove the exploit, we do not call it critical.
Support Remediation and Retest
Deliver remediation guidance, review fixes with engineering, and retest critical issues when the scope includes confirmation.
Typical outputs: reproducible findings, technical report, executive summary, remediation guidance, and retest expectations aligned to the project scope.
How We Scope
Use these models to self-select the right scoping path. Final scope depends on the target surface, access model, complexity, and whether code review or research work is included.
Focused Surface Review
Best for one product surface that needs a clear security decision path.
One scoped target such as Web, API, or Mobile
- Best fit for startup or product teams with one primary release surface
- Evidence-backed findings and remediation guidance
- Technical report and executive summary
- Upgrade when multiple connected surfaces or deeper access paths matter
Multi-Surface Assurance
Best for interconnected products that need deeper workflow and authorization coverage.
Two connected scopes or one complex authenticated surface
- Best fit for SaaS, fintech, or complex authenticated products
- Business logic and authorization depth across the scoped attack surface
- Developer remediation session and prioritized outputs
- Upgrade when code review or research-heavy testing is required
Custom Research Scope
Best for teams already running scanners and want human validation of exposure and dynamic findings.
DAST validation, authenticated dynamic testing, and attack surface verification
- Best fit for critical components and deeper technical unknowns
- Secure code review or targeted research-heavy work as scoped
- Root-cause analysis and remediation engineering guidance
- Use when standard pentesting visibility is not enough
Research Depth That Supports Security Delivery
CyberXhunt leads with publicly verifiable research work, recognized findings, and hands-on operator credibility — not placeholder testimonials or invented logos.
