We break in before the attackers do
BurgSec delivers elite penetration testing, red teaming, and adversary simulation — exposing the vulnerabilities that automated tools miss.
Services
Offensive security, done right
Every engagement is manual, methodology-driven, and tailored to your attack surface. No automated scan reports disguised as pentests.
Web Application Pentesting
Deep manual testing of web applications following OWASP methodology. We find business logic flaws, auth bypasses, and injection vectors that scanners can't.
API Security Testing
Comprehensive assessment of REST, GraphQL, and gRPC APIs. We test authentication flows, authorization models, rate limiting, and data exposure risks.
Mobile Application Pentesting
Reverse engineering and dynamic analysis of iOS and Android applications. We assess client-side security, API communication, and data storage practices.
Red Teaming & Adversary Simulation
Full-scope adversary simulation that tests your detection and response capabilities. We emulate real threat actors using custom TTPs aligned with MITRE ATT&CK.
Active Directory Exploitation
Targeted assessment of Active Directory environments. We enumerate trust relationships, abuse delegation, and demonstrate domain compromise paths.
Compliance & Gap Assessment
ISO 27001 gap analysis, NIST framework alignment, and ISMS consulting. We help you understand where you stand and build a roadmap to compliance.
Methodology
How we operate
Our methodology is built on industry frameworks — PTES, OWASP, and MITRE ATT&CK — adapted with real-world offensive experience.
Scoping & Reconnaissance
We define the engagement scope, rules of engagement, and conduct passive reconnaissance to map your external attack surface.
Enumeration & Analysis
Active enumeration of targets, technology fingerprinting, and identification of potential attack vectors through manual and automated techniques.
Exploitation & Pivoting
Controlled exploitation of identified vulnerabilities. We chain findings together, escalate privileges, and pivot through your environment — just like a real adversary.
Reporting & Remediation
Detailed technical report with proof-of-concept evidence, risk ratings, and actionable remediation guidance. We debrief your team and support re-testing.
Why BurgSec
Built for teams that take security seriously
Certified Offensive Experts
Our team holds OSCP, OSCE, CEH, and CRTP certifications. We're practitioners, not paper auditors — we've worked on real engagements across finance, healthcare, and tech.
Manual-First Approach
We don't rely on automated scanners. Every finding is manually verified, chained, and demonstrated with clear proof-of-concept exploits.
Actionable Reporting
Our reports are written for both executives and engineers. Every finding includes business impact, technical detail, and step-by-step remediation.
Continuous Partnership
Security isn't a one-time event. We offer retesting, ongoing PTaaS subscriptions, and advisory services to keep your defenses evolving.
Case Studies
Real findings, real impact
Anonymized findings from real engagements. These are the kinds of vulnerabilities we uncover — not theoretical risks, but exploitable attack chains.
Authentication Bypass via JWT Manipulation
Discovered a JWT algorithm confusion vulnerability allowing any authenticated user to forge admin tokens. Combined with an IDOR on the user management API, this granted full administrative access to all tenant accounts.
Business Impact
Complete account takeover across 2,400+ tenant organizations.
Domain Admin via Kerberos Delegation Abuse
Starting from a compromised workstation, we abused unconstrained Kerberos delegation on a print server to capture a Domain Controller TGT. This was leveraged to perform a DCSync attack and extract all domain credentials.
Business Impact
Full domain compromise from a single workstation in under 4 hours.
SSRF to Internal Network Pivot
An SSRF vulnerability in the document processing endpoint allowed us to reach internal microservices. We chained this with a misconfigured Redis instance to achieve remote code execution on the internal network.
Business Impact
Access to PHI data stores and internal infrastructure from an unauthenticated endpoint.
