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.

Web Application Penetration Testing

Full-scope manual testing of web applications, APIs, and authentication systems against real-world attack techniques.

Active Directory & Internal Network

Simulate insider threats and lateral movement across your Windows domain environment from initial foothold to domain compromise.

Network Infrastructure Testing

External and internal network assessments that identify exposed services, misconfigured systems, and exploitable network-level vulnerabilities.

Security Consulting

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.
