Security Assessment
Penetration Testing
Manual, objective-driven testing that chains real weaknesses together to demonstrate genuine business impact — safely and under contract.
- External and internal network penetration testing
- Web application and API testing (OWASP Top 10 and beyond)
- Active Directory attack-path analysis
Proof, not theory
Overview
Our testers work the way attackers work: reconnaissance, initial access, privilege escalation, lateral movement and objective. The difference is that everything happens under a signed scope with defined rules of engagement and no damage to production.
You receive an executive summary your board can act on, a technical report with full reproduction steps, evidence for every finding, and a debrief call where your engineers can ask questions directly of the tester who found the issue. A remediation retest is included.
Techx4u penetration testing services include external penetration testing and internal penetration testing, network penetration testing, and advanced penetration testing of Active Directory. An Active Directory security assessment or Active Directory penetration testing covers privilege escalation testing, lateral movement testing and attack path analysis, showing exactly how an attacker could move from one account to full control.
Internal network security testing starts from inside your network, as a compromised laptop or rogue insider would; external network security testing starts from the internet, as an outside attacker would. As a penetration testing company we include a retest of confirmed findings with every engagement.

FAQ
Frequently asked questions
What is penetration testing?
Penetration testing is an authorised, simulated attack on your systems, carried out by ethical hackers to find and prove exploitable weaknesses before a real attacker does. Unlike an automated vulnerability scan, a penetration test chains issues together, confirms real-world impact and gives you evidence and fix guidance for each finding.
Will testing disrupt our production systems?
Testing is conducted under agreed rules of engagement. Denial-of-service and destructive techniques are excluded by default, and we maintain a live communication channel throughout so anything unexpected is stopped immediately.
What standards do you follow?
Engagements are aligned to PTES, the OWASP Testing Guide and OSSTMM, and mapped to MITRE ATT&CK so findings connect directly to your detection coverage.
Is a retest included?
Yes. One remediation retest of the confirmed findings is included in the engagement, with an updated report issued afterwards. It needs to happen within the retest window agreed at kick-off, which is normally 90 days; beyond that the environment has usually changed enough to warrant a fresh test.

Ready to move on Penetration Testing?
We will scope it against your actual environment, not a generic package, and give you a fixed price before any work starts.
