What Is a Network Security Audit?
A Network Security Audit is a structured review of your environment—covering networks, servers, endpoints, identities, and controls—to identify vulnerabilities, misconfigurations, and compliance gaps. AEGIS evaluates your technical safeguards (firewalls, segmentation, endpoint protection), administrative controls (policies, change management, access reviews), and operational processes (patching, logging, backups, incident response). The outcome is a prioritized remediation roadmap aligned to risk and business impact.
Methodology: What We Review
- Discovery & Scoping: Asset inventory, data flows, crown-jewel systems, third-party exposure.
- Configuration & Hardening: Firewalls, switches, wireless, servers, endpoints, cloud services.
- Identity & Access: AD/Azure AD, MFA, privileged access, joiners/movers/leavers, role design.
- Vulnerability & Patch: Scanning baselines, patch SLAs, exception handling, zero-day posture.
- Logging & Monitoring: Syslog/EDR/SIEM coverage, alert fidelity, retention, response workflows.
- Data Protection: Backups & restores, encryption at rest/in transit, key management, DLP.
- Policies & Training: Security policy stack, awareness, incident runbooks, vendor risk.
- Resilience: Network segmentation, least privilege, RTO/RPO validation, tabletop results.
What You’ll Receive
- Executive Summary: Business-level risks, heatmap, and quick wins.
- Technical Findings: Evidence, severity, affected assets, and root cause.
- Prioritized Remediation Plan: Clear tasks with owners, effort, and dependencies (30/60/90-day).
- Compliance Alignment: Mapping to PCI-DSS, HIPAA, GDPR, NIST CSF, or CIS v8.
- Optional Validation: Re-test to confirm fixes and update the risk register.
Timeline — How Long Does an Audit Take?
- Small environments (≤25 endpoints, 1–2 servers): ~3–5 business days.
- Mid-size (25–250 endpoints, multi-site or cloud): ~1–2 weeks.
- Large/regulated (250+ endpoints, complex compliance): ~2–4+ weeks.
Exact timing depends on access, documentation availability, and scope (e.g., compliance depth, third-party integrations).
Pricing — How Much Does an Audit Cost?
We price transparently using common industry models. Final quotes vary by size, complexity, and compliance scope.
- Per-endpoint baseline: Typical discovery + vulnerability/config review in the $40–$120 per endpoint range (volume tiers apply).
- Flat project tiers: Small business packages often land between $3,000–$9,000; mid-market programs between $10,000–$45,000; complex/regulated audits can exceed this.
- Add-ons: Pen testing, red team exercises, incident tabletop drills, policy authoring, and remediation assistance are scoped separately.
We’ll scope your environment and provide a line-item proposal before kickoff.
Working with Your IT Team
Absolutely. We partner with internal IT and MSPs—sharing evidence, explaining findings, and aligning on remediation that fits your tooling and change windows. We’re here to help, not replace your team.
On-Site or Remote
AEGIS can perform audits fully remote or on-site. We’re based in Southeast Georgia and provide convenient local on-site service. We also travel anywhere in the USA when in-person presence is preferred or required.
FAQ
What is a network security audit?
A structured assessment of your security controls, configurations, and processes to identify risk and compliance gaps, culminating in a prioritized remediation plan.
How long does an audit take?
Small: ~3–5 business days; mid-size: ~1–2 weeks; large/regulated: ~2–4+ weeks—driven by scope, access, and documentation readiness.
How much does an audit cost and how is it priced?
Common models include per-endpoint baselines ($40–$120/endpoint), flat-fee packages ($3k–$9k small, $10k–$45k+ mid/enterprise), plus optional add-ons (pen testing, policy work). We provide a clear quote after scoping.
I already have an IT staff—will you work with them?
Yes. We collaborate closely with internal teams, MSPs, and leadership to ensure findings are actionable and remediation aligns with business priorities.
Can we meet in person?
Yes. We can meet on-site anywhere in the USA. Based in Southeast Georgia, we also offer easy local on-site service. Remote delivery is available for all services.
Types of Audits
Standard Security Audit
An end-to-end review aligned to best practices (e.g., CIS Controls, NIST CSF). We examine perimeter and internal networks, segmentation, endpoint baselines, identity and access, patch/vulnerability management, logging/monitoring, backup and recovery, and security policy health. Findings are risk-ranked with a 30/60/90-day remediation plan and design recommendations (e.g., MFA rollout, privileged access hardening, SIEM/EDR tuning, segmentation).
PCI Compliance Audit
Focused on the Cardholder Data Environment (CDE) and systems that store, process, or transmit PAN. We validate scope reduction techniques (tokenization, outsourcing), network segmentation, secure configurations, vulnerability management cadence, change control, log collection/retention, and incident response readiness. Deliverables map to PCI-DSS requirement families, highlighting compensating controls and remediation steps to support your SAQ or ROC process.
- Scope confirmation, data-flow diagrams, and segmentation testing.
- Secure configurations & hardening for CDE components.
- Vulnerability scanning program and patch SLAs.
- Logging/monitoring of critical events and file integrity.
- Policy evidence: access control, key management, vendor risk.
HIPAA Compliance Audit
Centers on safeguarding ePHI across clinical apps, EHRs, and infrastructure. We assess administrative, physical, and technical safeguards; BAAs; minimum necessary access; audit controls and alerts; encryption; and breach response. Output includes a Security Risk Analysis (SRA) with likelihood/impact scoring, gap analysis, and a corrective action plan suitable for covered entities and business associates.
- Access governance for workforce and privileged roles; MFA for remote and admin access.
- Audit logs: who accessed which records, when, and from where.
- Endpoint/server hardening, patching cadence, and EDR effectiveness.
- Backup/DR validation for RTO/RPO and periodic restore testing.
- Policies & workforce training alignment with HIPAA requirements.
GDPR Assessment
Focuses on personal data lifecycle: collection, lawful basis, minimization, consent, retention, and data subject rights. We review privacy notices, DPIAs, processor agreements, cross-border transfers, and technical measures (encryption, pseudonymization, access controls). You’ll receive a gap analysis with remediation tasks prioritized by regulatory risk and operational feasibility.
- Data mapping: systems, third parties, and transfer mechanisms.
- Rights enablement: access, rectification, erasure, portability, objection.
- Security of processing: least privilege, logging, monitoring, and breach response.
- Records of processing and retention schedules.
