At BOSSEC, Cybersecurity is more than a service — it is our core mission. We combine deep technical expertise with structured methodologies to deliver security assessments that create real, lasting value for our clients.

Attack surface from all anglesActive Directory Testing
From user to Domain AdminWe protect what matters most. Our Cybersecurity experts combine proven methodologies with real-world attack techniques to identify vulnerabilities across your entire digital footprint. Every engagement is tailored to your environment and delivered with the clarity your team needs to take action.
Passive intelligence gathering from public sources, mapping your digital footprint before an attacker gets the chance.
In-depth analysis of your web applications covering injection flaws, authentication bypasses and the full OWASP Top 10.
Systematic assessment of your internet-facing infrastructure, seen exactly as an attacker would see it from the outside.
Simulating a threat actor already inside your network to test lateral movement paths and understand your true internal exposure.
End-to-end AD assessment tracing the full path from a standard domain user to complete domain compromise.
Every finding risk-rated and documented with clear remediation guidance for both technical teams and executive stakeholders.
Every BOSSEC engagement runs through the same five-phase process — from initial reconnaissance to the final report. Here is what a typical assessment looks like in motion.
Cyber threats don't wait for a convenient time. BOSSEC helps you identify your exposure now, before someone else does it for you.
A Cybersecurity company built on precision, expertise, and a genuine commitment to protecting our clients.
At BOSSEC, Cybersecurity is more than a service. It is our core mission. We operate with a strong focus on precision, reliability and structured methodologies, ensuring that every engagement is carried out with the highest level of professionalism.
Our approach combines deep technical expertise with efficient processes, enabling us to deliver high-quality penetration testing and security assessments tailored to the specific needs of each client. No two organizations face the same risks, which is why we adapt our methodology to your environment rather than applying a one-size-fits-all template.
We believe that true security comes from understanding how attackers think. By replicating real threat actor techniques in a controlled, fully authorized environment, we give our clients a clear and honest picture of their exposure before anyone else finds it.
Every test, every finding and every report is executed with exactness and care. We do not guess; we verify.
Consistent methodology, clear communication and deliverables you can depend on. We keep our commitments.
Structured, repeatable processes grounded in industry best practices and real-world threat intelligence.
No black-box reporting. Every finding is fully explained, properly contextualized and clearly actionable.
Discover what attackers can learn about your organization before they act.
Open Source Intelligence (OSINT) is the systematic collection and analysis of publicly available information to build a detailed picture of a target. BOSSEC conducts passive reconnaissance against your organization using the same techniques real attackers use — with zero direct interaction with your live systems required.
Attackers invest significant time in passive reconnaissance before launching an active campaign. The more information they gather without touching your systems, the more precise and damaging their eventual attack becomes. Understanding your own exposure from the outside is the first and most critical step toward controlling it.
Identify vulnerabilities in your web applications before attackers do.
Web applications are among the most frequently targeted attack vectors. BOSSEC conducts thorough, manual-first web application penetration tests that go significantly beyond automated scanning to uncover complex vulnerabilities that tools simply cannot detect on their own.
We use a combination of automated tooling for breadth and targeted manual testing for depth. Every identified vulnerability is manually validated to eliminate false positives before it appears in your report. The goal is not a long list of theoretical issues but a precise, accurate and actionable picture of your real risk.
Test your defenses from the outside, exactly as an attacker would approach them.
An external penetration test simulates an attack conducted by a threat actor with no prior access to your environment. Starting from the open internet, BOSSEC assesses all of your internet-facing assets to identify and validate exploitable vulnerabilities before a real attacker can.
We move systematically from passive reconnaissance through active scanning to controlled exploitation, validating every vulnerability we identify along the way. The objective is to understand your real-world risk, not just compile a theoretical list of potential issues.
How far can an attacker get once they are already inside? Find out before they do.
An internal penetration test answers a critical question: what happens when an attacker gets past the perimeter? BOSSEC simulates a threat actor who has already gained initial access — through a phishing campaign, a compromised credential or a breached third party — and tests how far they can realistically move through your internal environment.
Internal networks often operate on a foundation of implicit trust. Once inside, legacy systems, misconfigured services, cached credentials and over-permissioned accounts frequently allow rapid lateral movement across the entire environment. Understanding this exposure is essential for any realistic security posture.
Control your Active Directory — or an attacker will. Know your exposure before they do.
Active Directory is the backbone of most enterprise IT environments. When an attacker controls it, they control everything — every user, every system and every service in the organization. That is why it is the primary objective in virtually every serious internal attack.
The path to full domain compromise rarely requires a zero-day. It almost always runs through accumulated misconfiguration, weak credentials and unreviewed permissions that have built up over years of normal operations.
Precision-engineered Cybersecurity assessments that deliver real value, not checkbox compliance.
Every engagement follows a defined, fully reproducible process. Reconnaissance, enumeration, exploitation, post-exploitation and detailed reporting. No shortcuts and no gaps in coverage.
We do not run automated scans and call it a penetration test. Every finding is manually validated before it reaches your report, eliminating false positives entirely.
Each vulnerability comes with full context including technical detail, business impact assessment, a CVSS score and step-by-step remediation guidance your team can act on immediately.
We replicate the actual techniques threat actors use in real engagements, not generic templates. Your defenses are tested against realistic, current attack scenarios.
Every engagement delivers both an executive summary for leadership and a detailed technical report for your security team. No translation layer required between the two.
Many Cybersecurity firms treat penetration testing as a compliance exercise to be completed and filed. BOSSEC treats it as what it actually is: a controlled adversarial simulation designed to reveal your true exposure before a real attacker finds it.
