Offensive Security & VAPT
Network Penetration Testing
We test your external perimeter and internal network for exploitable weaknesses - misconfigurations, weak services, segmentation gaps and privilege-escalation paths - using manual exploitation mapped to PTES and CERT-In expectations.
Typical timeline
8–12 business days
Engagement model
Grey / black / white box
How it runs
Kickoff → test → report → re-test
Overview
We simulate realistic network attacks to identify security vulnerabilities across your external perimeter and internal domain architecture.
Our testers perform manual exploitation of weak services, configuration issues, and Active Directory paths to trace lateral movement avenues.
At a glance
- External perimeter and internal network testing
- Segmentation, lateral-movement and privilege-escalation analysis
- Manual exploitation with proof-of-concept
- CVSS-rated findings and remediation roadmap
Coverage
What we cover
External Perimeter Rules
Auditing firewalls, VPN endpoints, and publicly exposed services for exploitation paths.
Active Directory Exploits
Testing Kerberoasting, AS-REP roasting, and domain escalation vectors.
Internal Subnet Segments
Verifying network segmentation controls between guest, corporate, and production zones.
Service Vulnerabilities
Attempting manual exploitation of legacy or unpatched network services.

Why A5
Why teams pick us
Manual-first, not scan-first
Senior testers hand-craft test cases for your business logic - scanners only set the baseline.
Proof, not guesses
Every finding ships with a working proof-of-concept and exact reproduction steps.
Fix-focused reporting
Remediation with code and config examples, not just a CVSS number and a shrug.
Re-test included
We verify your fixes and issue a clean report - closure, not just discovery.
FAQ
Frequently asked
Internal or external?
Both - we cover external perimeter and internal/assumed-breach scenarios, scoped to your needs.
