Assessments Built for
Real-World Threats
Every ChainLenk engagement is manual, scoped to your environment, and delivered with the depth of documentation your team needs to remediate effectively.
What We Test
From web applications to enterprise Active Directory environments, ChainLenk covers the attack surfaces that matter most.
Full-scope manual testing of web applications, APIs, and authentication systems against real-world attack techniques.
Simulate insider threats and lateral movement across your Windows domain environment from initial foothold to domain compromise.
External and internal network assessments that identify exposed services, misconfigured systems, and exploitable network-level vulnerabilities.
Strategic guidance on hardening your environment, security architecture review, framework alignment, and remediation validation.
Web Application Testing
Manual testing across the full OWASP Top 10 and beyond — authentication, authorization, injection, business logic, and client-side security. We cover every entry point a real attacker would probe.
Authentication & Session Management
Testing for weak credentials, broken authentication flows, session fixation, token predictability, and improper logout handling.
Injection & Input Validation
SQL injection, command injection, SSTI, XXE, and all OWASP Top 10 injection categories across every user-controlled parameter.
API Security Testing
REST and GraphQL API enumeration, BOLA/IDOR testing, authentication bypass, excessive data exposure, and rate limit abuse.
Business Logic Vulnerabilities
Workflow abuse, privilege escalation, price manipulation, and access control flaws that automated scanners routinely miss.
Active Directory & Internal Network
Simulate a real insider threat or post-compromise attacker operating inside your network. We identify every viable path to domain dominance — before a threat actor does.
Domain Enumeration
BloodHound/SharpHound mapping of attack paths, ACL abuse vectors, and misconfigured delegation relationships across the domain.
Credential Attacks
Kerberoasting, AS-REP Roasting, Pass-the-Hash, Pass-the-Ticket, and NTLM relay attacks to demonstrate credential exposure.
Lateral Movement & Privilege Escalation
Full attack chain from initial foothold through lateral movement to Domain Admin — documented at each step with evidence.
Persistence & Post-Exploitation
Golden/Silver ticket attacks, DCSync, GPO abuse, and persistence mechanisms that demonstrate attacker dwell-time risk.
Network Infrastructure Testing
External and internal network assessments that map your real attack surface and validate whether your segmentation and perimeter controls hold up under real-world attack techniques.
External Attack Surface Mapping
Comprehensive enumeration of internet-facing assets, open ports, exposed services, and forgotten infrastructure.
Service & Protocol Exploitation
Testing for vulnerabilities in exposed services, weak cipher suites, default credentials, and unpatched network devices.
Network Segmentation Validation
Verification that your network segments actually restrict lateral movement — firewall rule testing, VLAN hopping, and pivot path identification.
Wireless Assessment
WPA2/WPA3 configuration review, rogue AP detection, evil twin testing, and client isolation validation.
Security Consulting
Beyond point-in-time testing — strategic guidance to improve your overall security posture, validate remediation efforts, and communicate risk to stakeholders at every level.
Security Architecture Review
Analysis of your network topology, access controls, authentication design, and security tooling for gaps and architectural weaknesses.
Remediation Validation
Post-remediation retesting to verify that identified vulnerabilities have been resolved and no regression was introduced.
Framework Alignment
Gap analysis and advisory support for NIST CSF, NIST SP 800-53, CIS Controls, and MITRE ATT&CK mapping.
Executive Briefings
Clear risk communication for leadership teams — translating technical findings into business risk language that informs real decisions.
Every Engagement
Our Methodology
Scoping & Kickoff
Define objectives, rules of engagement, testing windows, and success criteria. We align on exactly what's in scope before anything starts.
Reconnaissance & Enumeration
Systematic discovery of your attack surface — services, technologies, credentials, and potential entry points — mirroring real attacker methodology.
Exploitation & Validation
We safely exploit discovered vulnerabilities to demonstrate real-world impact, chaining findings where possible to show the full attack path.
Reporting & Remediation Guidance
Detailed reports with risk ratings, reproduction steps, and prioritized remediation recommendations — written for both technical and executive audiences.
What You Receive
Every ChainLenk engagement includes professional documentation that gives your team everything needed to understand, communicate, and remediate findings.
Executive Summary
A concise overview of findings, overall risk posture, and business impact — written for leadership, not just engineers.
Technical Report
Full technical documentation of every finding with CVSS scores, reproduction steps, and evidence screenshots.
Remediation Roadmap
Prioritized remediation guidance sorted by risk and complexity — so your team knows what to fix first.
MITRE ATT&CK Mapping
Findings mapped to ATT&CK techniques and tactics for threat modeling and detection engineering use.
Proof-of-Concept Evidence
Every exploitable finding includes working reproduction steps so your developers can reproduce and verify the fix.
Remediation Validation
Optional retesting after remediation to confirm findings have been resolved and no new issues were introduced.
