Penetration Testing Services for Every Attack Surface
Network penetration testing, web application penetration testing, wireless, social engineering. Pick the scope you need; we'll help you sequence the rest.
External Network Penetration Testing
What an attacker sees from the internet. Perimeter discovery, service enumeration, exploitation, and privilege escalation against your public-facing infrastructure.
Internal Network Penetration Testing
Simulates an attacker already inside — stolen laptop, malicious insider, or breach follow-on. Active Directory, segmentation, lateral movement, and domain dominance testing.
Web Application Penetration Testing
OWASP Top 10, authentication bypass, session management, IDOR, SSRF, business logic. Authenticated and unauthenticated testing against your web apps and APIs.
Wireless Penetration Testing
WPA2/WPA3, enterprise authentication, rogue access point detection, guest network isolation. Tests the wireless attack surface from the parking lot.
Phishing Simulation & Social Engineering
Targeted phishing campaigns, pretext calling, and physical social engineering (where authorized). Measures human-layer defenses and drives awareness training.
Vulnerability Assessment
Comprehensive scanning with triaged, prioritized findings. Ideal recurring exercise between penetration tests — monthly or quarterly cadence.
Red Team Exercises
Goal-based, stealth-focused engagements that test detection and response capability. Multi-week campaigns with explicit objectives (e.g., access CFO email, exfiltrate customer data).
Retest & Remediation Support
Free retest of critical findings within 90 days. Remediation guidance and, for managed IT clients, hands-on fixes by our engineering team.

Penetration Testing FAQ
What is a penetration test and how is it different from a vulnerability scan?
A vulnerability scan is automated discovery of known weaknesses. A penetration test is a human-led simulated attack that chains vulnerabilities together to demonstrate real business impact. Scans answer 'what is misconfigured.' Pentests answer 'what can an attacker actually do.'
How much does a penetration test cost?
Penetration testing cost varies by scope: external network, internal network, web application, wireless, and social engineering are priced separately. A typical external test for a mid-market business ranges $5,000–$15,000; web application tests $8,000–$25,000. Contact us for a scoped quote.
Which pentest do I need first?
For most Dallas businesses, start with an external network penetration test (what an outside attacker sees) plus a phishing simulation. Add internal network and web application testing once you've remediated external findings. Compliance (PCI, HIPAA, SOC 2) may dictate specific scopes.
Do you provide web application penetration testing?
Yes. Our web application penetration testing covers OWASP Top 10, authentication, session management, business logic flaws, API security, and SSRF/IDOR classes of vulnerabilities. Deliverables include a findings report with proof-of-concept steps and retest confirmation after remediation.
How long does an external penetration test take?
Typical external network penetration testing runs 1–2 weeks for discovery and active testing, plus 1 week for report delivery. We schedule the window around your business needs and can do after-hours testing for sensitive environments.
Do you support remediation after findings?
Yes. Our penetration testing services include a remediation plan, co-ordination with your IT team (ours or yours), and a free retest of critical findings within 90 days. For clients on a managed IT engagement, remediation is handled by our engineering team.
Are you a CISSP-led security team?
Yes. GXA's cybersecurity practice is led by CISSP-credentialed professionals with over 20 years of combined experience. All pentest reports are reviewed by senior staff before delivery.
