From remote IT support in Orange County to full business IT support services, we make technology simple, secure, and cost-effective.
Most businesses don't discover their network security gaps until after an incident. A firewall misconfiguration that's been quietly passing unauthorized traffic for two years. An unencrypted wireless network segment that nobody documented. A VPN with default credentials that an attacker found in fifteen minutes. These aren't hypotheticals — they're the findings we uncover regularly in network security audits across Orange County businesses that thought they were protected.
Burgi Technologies delivers comprehensive IT security assessments that examine your network from every angle: infrastructure, access controls, wireless environments, cloud connections, remote access, and compliance posture. We document what we find, explain the risk in plain language, and help you fix what matters most.
We carry a 5.0-star rating from 60+ verified reviews and back every audit with our 100% happiness guarantee. If our audit doesn't provide clear, actionable security intelligence, you don't pay.
A network security audit is a structured assessment of your IT infrastructure designed to identify security weaknesses, configuration errors, compliance gaps, and architectural risks before attackers or auditors find them. It goes well beyond a vulnerability scan — it combines automated tooling with manual expert review to evaluate not just what's technically present, but whether your security controls are actually working as intended.
A thorough network security audit in Orange County answers questions that keep IT managers up at night:
The answers to these questions are the foundation of an honest security posture assessment.
Networks change constantly. New devices are added, configurations are modified, cloud services are connected, and employees join and leave. Each change introduces potential security gaps. A network that was properly configured twelve months ago may have significant exposure today — not because of negligence, but because of the natural entropy of active IT environments.
Beyond internal change, the external threat landscape evolves continuously. New attack techniques emerge, new vulnerabilities in widely-used products are disclosed, and attackers develop new methods of bypassing controls that worked six months ago. Regular audits ensure your defenses keep pace with both internal changes and external threats.
There are also regulatory drivers. HIPAA, PCI-DSS, the FTC Safeguards Rule, and CMMC all include requirements for periodic security assessments. Many cyber insurance carriers now require evidence of recent security audits as a condition of coverage — or factor it significantly into premium calculations. An audit isn't just good practice; it's often a business requirement.
Burgi Technologies follows a structured, five-phase audit methodology that ensures complete coverage while minimizing disruption to your operations.
Every audit begins with a scoping conversation where we understand your business environment, regulatory obligations, areas of highest concern, and any recent changes that may be relevant. We gather network diagrams, asset inventories, and existing documentation — and identify gaps where documentation doesn't match reality.
Automated discovery tools map your network to identify all connected devices, open services, and communication paths. This asset inventory often reveals surprises: undocumented systems, shadow IT deployments, and forgotten test environments that have been quietly running for years.
We run authenticated internal scans and external unauthenticated scans to identify known vulnerabilities across all in-scope systems. Scan results are enriched with current threat intelligence to flag vulnerabilities that are actively being exploited in the wild. This phase produces the raw technical findings that our analysts then evaluate and contextualize.
This is where our network penetration testing capability separates a real audit from a scan report. Our security engineers manually test your environment using the same techniques that sophisticated attackers use:
Manual testing catches complex attack paths that automated tools miss — the chained vulnerabilities and logic flaws that require human reasoning to identify and exploit.
Every finding is documented with a clear description of the vulnerability, the evidence that supports it, the potential business impact if exploited, and specific remediation guidance. Findings are rated using a risk scoring methodology that considers both technical severity and business context.
We deliver two versions of every audit report: a technical report for your IT team with detailed findings and remediation steps, and an executive summary for leadership that communicates risk in business terms without requiring security expertise to understand.
An audit report that sits on a shelf helps nobody. Burgi Technologies provides active remediation support — we work with your team to implement fixes, verify that remediation was effective, and prioritize the sequencing of improvements to get the most risk reduction for your effort. Critical findings get addressed first; lower-risk items are scheduled into your normal change management process.
A remediation verification scan confirms that identified vulnerabilities have been resolved and new issues haven't been introduced during the fixing process.
Our IT security assessments cover every layer of your network infrastructure:
We review firewall configurations for rule bloat, overly permissive policies, implicit allow rules, and unused or outdated rules that expand your attack surface. Firewall rule analysis frequently surfaces rules added for one-time projects and never removed, creating permanent security gaps.
VLAN configuration, spanning tree settings, port security, and inter-VLAN routing policies determine whether an attacker who compromises one network segment can reach others. We validate that segmentation controls actually enforce the isolation they're intended to provide.
Wireless security testing covers encryption standards, authentication mechanisms, guest network isolation, rogue access point detection, and management interface security. Many businesses have wireless networks that technically use WPA2 but are still misconfigured in ways that allow unauthorized access or lateral movement.
With remote work now standard, VPN security is critical. We evaluate authentication strength (MFA enforcement, certificate vs. password authentication), split tunneling configurations, client security posture checking, and whether remote access policies are actually being enforced.
Cloud environments introduce unique security considerations. We assess cloud security configurations, data transfer encryption, identity federation, and the security of connections between on-premises infrastructure and cloud platforms (Azure, AWS, Microsoft 365, Google Workspace).
Our audit methodology maps directly to major compliance frameworks, allowing a single engagement to satisfy multiple audit requirements:
Audit documentation is formatted to support regulatory submissions and satisfy auditor requests. Our IT compliance audit services extend this capability into formal compliance program management. For comprehensive ongoing security, explore our managed cybersecurity services. We also recommend pairing your audit with continuous vulnerability management to maintain the security posture we establish during the audit.
Audit frequency should reflect your risk environment and regulatory obligations. Our general recommendations for Orange County businesses:
Timeline depends on the size and complexity of your environment. For a typical Orange County SMB with 25-100 users, a comprehensive audit including manual testing takes five to ten business days from kickoff to final report delivery. Larger or more complex environments may take two to four weeks. We work within your operational constraints and schedule active testing during low-impact windows to avoid disruption.
We design our audit methodology to be non-disruptive. Passive network monitoring and documentation review cause zero impact. Active scanning is scheduled during off-hours or low-use periods and tuned to avoid overwhelming your infrastructure. Manual penetration testing is conducted carefully to avoid accidental service disruption. We communicate all planned active testing in advance so your team is prepared.
A network security audit is broader in scope: it covers configuration review, documentation assessment, compliance mapping, architecture analysis, and vulnerability assessment across your entire environment. A penetration test is more focused: it attempts to actively exploit vulnerabilities to demonstrate real-world attack feasibility. Our comprehensive audit engagements include penetration testing elements — specifically network penetration testing — as part of the manual testing phase, giving you both the breadth of an audit and the depth of a pen test.
We provide a pre-audit checklist during scoping that covers documentation to gather (network diagrams, asset lists, existing security policies) and credentials needed for authenticated scanning. If documentation doesn't exist, that's fine — we've conducted hundreds of audits in environments with minimal documentation and our discovery process fills the gaps. The main thing we ask is that your IT contact person is available for questions during the assessment period.
You don't know what's hiding in your network until you look. Burgi Technologies has conducted hundreds of network security audits in Orange County, and we consistently find significant issues in environments that clients believed were secure. That's not a criticism — it's the nature of complex, evolving network environments. The goal isn't a perfect network; it's a network where risks are known, prioritized, and actively managed.
