Advanced Network Penetration Testing Services That Fortify Your Infrastructure

Fortune 500 & Businesses Across America Trust Our Proven Network Security Testing Experts

Is your network perimeter really secure? Xperts Unlimited delivers comprehensive network penetration testing services that expose critical vulnerabilities in your network infrastructure before cybercriminals find them. Our advanced methodology targets both internal and external network attack vectors, because modern network security requires testing every entry point that hackers could exploit.

Built On Trust, Driven By Innovation In Network Penetration Testing

Your network infrastructure faces sophisticated threats that evolve faster than traditional security controls can adapt. Unlike simple vulnerability scanners that only scratch the surface, our network penetration testing services simulate real-world attack scenarios across your entire network topology. 

We expose critical vulnerabilities in firewalls, routers, switches, and network segments that automated tools consistently miss.

From network reconnaissance to lateral movement exploitation, our network security specialists use advanced persistent threat techniques to demonstrate exactly how attackers breach network perimeters and move through internal systems. We don’t just identify network weaknesses, we actively exploit network vulnerabilities to prove business impact and provide network-specific remediation that transforms your infrastructure into a hardened fortress.

Perimeter Security Illusion

78% of successful breaches bypass perimeter defenses through network protocol exploitation, VPN vulnerabilities, and firewall misconfigurations that create hidden entry points

Internal Network Trust

Once inside your network perimeter, attackers move laterally through trusted network segments, escalating privileges and accessing sensitive data without additional authentication

Legacy Network Equipment

Older network devices run outdated firmware with known vulnerabilities that hackers exploit using automated scanning tools to gain initial network access

Network Segmentation Failures

Poor network segmentation allows attackers to reach critical systems from compromised endpoints, turning single device infections into enterprise-wide data breaches

Why Your Network Is A Cybercriminal's Primary Target

Network infrastructure creates the foundation that either protects or exposes your entire business to cyber threats:

Frequently Asked Questions

Network penetration testing services are specialized cybersecurity assessments where certified ethical hackers simulate real-world attacks on your network infrastructure to identify vulnerabilities before cybercriminals exploit them. 

For SMBs, this is critical because 78% of successful breaches involve network compromise as the primary attack vector, and network vulnerabilities provide the foundation for most data theft incidents. Unlike basic network scans, our network penetration testing services actively exploit network weaknesses including firewall bypasses, protocol vulnerabilities, and network device compromises to demonstrate real business impact. 

This proactive approach helps you understand exactly how network breaches could affect your operations, data security, and business continuity—far more cost-effective than recovering from an actual network security incident.

Network penetration testing costs for LA and Orange County SMBs typically range from $3,500-$10,000 depending on your network infrastructure complexity, number of network segments, and internal/external testing scope. 

Unlike providers who charge unpredictable hourly rates, we offer transparent flat-rate pricing covering your complete network assessment including external perimeter testing and internal network evaluation. Cost factors include: network size and complexity, number of network devices, remote office locations, and compliance requirements. 

We prioritize local LA and Orange County businesses with competitive pricing packages, and this investment prevents network breaches that average significantly higher costs due to business disruption and data recovery expenses.

SMBs should conduct network penetration testing annually at minimum, with quarterly assessments recommended for businesses in regulated industries or those with frequent network changes. Immediate network testing is essential after: major network infrastructure updates, new firewall implementations, network topology changes, or security incidents. 

Unlike applications that update frequently, network infrastructure changes less often but requires testing when modifications occur. Many LA and Orange County businesses schedule biannual network assessments to maintain security posture while supporting business growth and regulatory compliance requirements that often mandate regular network security testing.

Network vulnerability scanning only identifies potential network weaknesses using automated tools, while professional network penetration testing actively exploits these vulnerabilities to demonstrate real attack scenarios and business impact. 

Scanners might detect an open network port or outdated network service, but network penetration testing actually exploits these findings to gain network access, escalate privileges, and demonstrate lateral movement through your network infrastructure. 

We use advanced techniques like network protocol exploitation, firewall bypass methods, and network device compromise; approaches that automated scanners completely miss. Think of vulnerability scanning as basic network health monitoring, while network penetration testing is comprehensive security validation revealing exactly how network attacks succeed.

Professional network penetration testing is designed to minimize business disruption while providing maximum network security insights. We conduct network assessments using carefully controlled testing methodologies, coordinate with your IT team for optimal timing, test network segments incrementally, and maintain constant communication throughout the process. 

Our approach includes: scheduling testing during maintenance windows, using non-destructive testing techniques initially, implementing safeguards against network service disruption, and providing real-time progress updates. 

Most network penetration testing activities focus on controlled exploitation that doesn’t affect normal business operations, with any potentially disruptive testing carefully coordinated to avoid operational impact.

Select a network penetration testing provider based on: certified network security expertise (CCNA Security, CISSP, GPEN certifications), hands-on network attack experience, SMB-specific network knowledge, transparent flat-rate pricing, and local support availability. 

Avoid providers who only offer automated scanning—network security requires specialized skills in network protocol exploitation, firewall bypass techniques, and network device security assessment. Look for detailed network testing methodologies, comprehensive network remediation guidance, and ongoing network security support options. 

For LA and Orange County businesses, prioritize providers who understand local compliance requirements and can provide immediate network security incident response when needed.

When we discover critical network vulnerabilities, we immediately notify your team with detailed risk classifications and provide step-by-step network-specific remediation guidance. 

Our network security experts help prioritize fixes based on business impact, starting with: patching critical network device vulnerabilities, correcting firewall configurations, implementing proper network segmentation, and updating network access controls. 

We don’t just identify network problems, we provide detailed network remediation playbooks, security configuration templates, and ongoing support to ensure vulnerabilities are properly resolved. Many clients schedule follow-up network assessments to verify that implemented fixes actually strengthen their overall network security posture.

Many industries require regular network penetration testing for compliance: PCI DSS mandates network testing for businesses processing payments, HIPAA requires network security assessments for healthcare organizations, SOX compliance often includes network infrastructure testing for public companies, and various state regulations require network security validation. 

Even without explicit requirements, network penetration testing demonstrates due diligence for cyber insurance claims and regulatory audits. California businesses face additional requirements under CCPA that include network data protection measures.

We help LA and Orange County SMBs understand specific network compliance requirements and provide documentation that satisfies auditors, insurance providers, and regulatory bodies.

Our network penetration testing process typically spans 1-3 weeks and includes: comprehensive network infrastructure discovery and mapping, external perimeter security testing, internal network security assessment, network device security evaluation, network segmentation testing, and detailed reporting with prioritized network remediation steps. 

You’ll receive regular progress updates, immediate notification of critical network vulnerabilities, and a comprehensive final report with executive summary, technical findings, and step-by-step network security improvements. 

We conclude with a network remediation planning session to help your team implement network security enhancements efficiently across your entire infrastructure.

Absolutely! Xperts Unlimited provides dedicated local network penetration testing support throughout Los Angeles and Orange County with offices in Marina del Rey and Irvine. Our local network security experts understand California compliance requirements, can provide immediate on-site network consultations when needed, and offer ongoing network security support.
