External Network Pentest
Your organization’s public-facing infrastructure is the first line of defense against cyber-attacks. Attackers routinely scan the internet for exposed services, outdated systems, misconfigurations, and weaknesses that can lead to unauthorized access or full compromise.
Our External Network Penetration Testing identifies vulnerabilities in your internet-facing assets and simulates real-world attack techniques used by threat actors to gain an initial foothold into your environment.
We go beyond automated vulnerability scans—providing deep manual analysis, exploitation attempts, attack path mapping, and risk-focused reporting.
Our Pentest Methodology
1
Scoping & Planning
We define testing objectives, validate external IP ranges and domains, confirm asset ownership, and establish safe testing windows to ensure a controlled, non-disruptive engagement.
2
Reconnaissance & Information Gathering
We perform external footprinting to identify publicly exposed systems, services, cloud assets, DNS records, certificates, and network infrastructure that form your internet-facing attack surface.
3
Threat Modeling & Attack Surface Analysis
We analyze exposed entry points, authentication portals, remote access services, misconfigurations, and high-value external assets to prioritize likely attacker paths and business-impacting risks.
4
Vulnerability Discovery & Exploitation
We conduct targeted testing of publicly accessible systems using a combination of automated scanning and manual techniques to identify exploitable weaknesses, misconfigurations, outdated software, and insecure interfaces.
5
Post-Exploitation & Risk Assessment
Where exploitation is successful (within scope), we assess real-world impact—such as unauthorized access, data exposure, foothold potential, or pivot opportunities—while maintaining strict safety controls.
6
Reporting & Remediation Support
You receive a detailed report with an executive narrative, technical findings, CVSS scoring, evidence, and prioritized remediation guidance, along with a complimentary retest to verify fixes.
What We Test
Our testing covers all critical areas of web application security
Perimeter Infrastructure
Firewalls, routers, load balancers, reverse proxies, DDoS protection mechanisms, ACLs, and NAT configuration.
Public-Facing Servers & Services
Web servers, mail servers, FTP/SSH, VPNs, remote management ports, and DNS servers.
Cloud & Hybrid Network Exposure
Misconfigured buckets (S3/Azure/GCP), exposed serverless endpoints, public VMs, and insecure cloud firewalls.
TLS/SSL & Certificate Security
Weak ciphers, outdated certificates, protocol fallback attacks, and HSTS misconfigurations.
Authentication & Access Points
VPN gateways, SSO portals, admin panels, remote desktop interfaces, MFA gaps.
DNS & Email Security
SPF/DMARC/DKIM issues, open resolvers, subdomain takeovers, and MX misconfigurations.
External APIs
Access control flaws, rate limiting issues, insecure endpoints, and sensitive data leaks.
Common Vulnerabilities
Remote code execution, Directory traversal, Default credentials, CVE exploitation, Misconfigured services,
Sensitive info disclosure (robots.txt, .git, etc.), Web server enumeration findings
We assess both commodity and advanced threats.

Frequently Asked Questions
Common questions about our web application penetration testing services
Typically, 1–2 weeks, depending on the number of IPs, domains, and services exposed.
Our tests are non-destructive and rate-limited. Any high-risk actions are conducted only with prior approval.
We need your IP ranges, domains, cloud assets, and any compliance requirements. No credentials are required unless testing specific authenticated interfaces
We test for known vulnerabilities, attack patterns, and misconfigurations. We also simulate advanced techniques but do not perform destructive zero-day exploitation.
Yes, upon request we perform a breach monitoring review and identify leaked credentials associated with your domain.
Retesting is available upon request and depends on the scope of remediation. We recommend connecting with our team to understand the best retesting approach for your environment.
