External Network Penetration Testing

Test your perimeter before attackers find a way through

NeedSec simulates an external attacker with no prior access to assess your internet-facing systems. We map your full attack surface, identify exploitable weaknesses, and show the real-world impact before a breach occurs.

Manual-led testing

Every assessment is led by a qualified security engineer — human judgment, not just automated scanning.

Evidence-backed findings

Each vulnerability includes proof of concept, reproduction steps, and a business-impact risk rating.

Actionable fix guidance

Reports are structured for developers and decision makers so remediation can start immediately.

What We Test

Focused testing against realistic attack paths

NeedSec combines manual testing, structured methodology, and business-focused reporting to identify issues that matter — not just scanner noise.

01

External attack surface mapping — IP ranges, domains, and subdomain enumeration

02

Port scanning and service fingerprinting across all exposed assets

03

Firewall and perimeter control bypass testing

04

VPN security — authentication strength and configuration weaknesses

05

SSL/TLS version, cipher suite, and certificate chain review

06

DNS security — zone transfer attempts, subdomain takeover, and DNSSEC review

07

Email security — SPF, DKIM, DMARC configuration and spoofing risk

08

Remote access services — RDP, SSH, and web admin portal exposure

09

Default credentials on network devices and management interfaces

10

Web-exposed services — login portals, staging environments, and forgotten assets

11

Public vulnerability identification and manual exploitation validation

12

Attack path mapping from external access to internal pivot points
