Penetration
Testing
Penetration testing is an authorised, simulated cyberattack against your infrastructure to find exploitable vulnerabilities before real adversaries do. Tristarnex conducts network, web application, social engineering, and red team assessments — and delivers findings your team can act on immediately.

External Network
Internet-facing infrastructure, firewalls, VPNs, exposed services, and perimeter controls.
Internal Network
Lateral movement opportunities, privilege escalation paths, and Active Directory misconfigurations.
Web Applications
OWASP Top 10, authentication flaws, injection vulnerabilities, broken access control, and API security.
Social Engineering
Phishing campaigns, vishing simulations, and physical access attempts against your people and premises.
Red Team Operations
Full-scope adversary simulation targeting your people, processes, and technology simultaneously.
Cloud Infrastructure
AWS, Azure, and M365 misconfigurations, IAM policy weaknesses, and storage exposure.
Our process
Scoping
We define the target environment, rules of engagement, and success criteria with you before any testing begins.
Reconnaissance
Passive and active information gathering to map your attack surface as a real adversary would — before touching any systems.
Exploitation
Controlled, authorised attempts to exploit identified vulnerabilities using real-world techniques and tooling.
Post-Exploitation
Where access is gained, we demonstrate real business impact: data access, lateral movement, privilege escalation.
Reporting
A clear, jargon-free report with every finding, its real-world risk, and a prioritised remediation plan your team can act on immediately.
Frequently asked questions
How long does a penetration test take?
Scope determines duration. A web application test typically takes 3–5 days. An internal network assessment runs 5–10 days. A full red team engagement can run 2–4 weeks. We agree timelines during scoping.
Will a penetration test disrupt our operations?
We test during agreed windows and maintain communication throughout. Critical production systems can be tested out-of-hours. Any potentially disruptive activity is flagged to you before it is executed.
What is the difference between a vulnerability scan and a penetration test?
A vulnerability scan is automated — it identifies known weaknesses from a list. A penetration test involves a human tester actively attempting to exploit those weaknesses and chain them together to achieve a business-impact objective. Scans miss logic flaws, misconfiguration chains, and social engineering vectors entirely.
What certifications do your penetration testers hold?
Our offensive security practitioners hold OSCP (Offensive Security Certified Professional), CREST CRT, CEH, and related certifications. Every test is led by a certified senior tester.
Do you provide a retest after remediation?
Yes. We include a targeted retest of all critical and high findings within 30 days of your remediation work. This confirms fixes are effective and gives you confidence before your next audit or client review.
