Security Audit & Firewall Engineering

Find the vulnerabilities before attackers do. Harden your network from the ground up with carrier-grade security engineering.

Most Networks Are Less Secure Than Their Owners Think.

Firewall rules accumulate over years. Policies get added, exceptions get made, and nobody ever goes back to clean up. The result is a security posture full of gaps — overly permissive rules, unused ACLs, misconfigured NAT, and exposure at layers that were never properly reviewed.

At AMROTS, we approach network security the same way we approach network design — methodically, thoroughly, and with the same carrier-grade standards we apply to everything we do. We find what’s wrong, explain it clearly, and fix it properly.

Why a Professional Security Audit Matters

A network security audit isn’t just a compliance checkbox — it’s a systematic review of every layer where an attacker could gain a foothold, move laterally, or exfiltrate data. Our audits are conducted by engineers who understand networking at a deep level, not just security tooling — which means we find issues that automated scanners and compliance frameworks routinely miss.

Firewall Policy Review

We review your firewall ruleset line by line — identifying overly permissive rules, redundant entries, shadow rules, and policy gaps that leave your network exposed. Every finding is documented with a clear remediation recommendation.

L4–L7 Security Assessment

Beyond basic port filtering, we assess application-layer security — inspecting DPI policies, SSL/TLS inspection configurations, application identification, and URL filtering to ensure your security stack is actually doing its job.

Network Segmentation

Flat networks are a security liability. We assess your segmentation strategy — reviewing VLAN design, inter-zone policy, micro-segmentation, and east-west traffic controls to ensure lateral movement is contained.

RPKI & BGP Security

For ISPs, carriers, and multi-homed enterprises, BGP security is critical. We review your RPKI implementation, route origin validation, BGP session security, and prefix filtering policies to protect your routing infrastructure from hijacking and leaks.

Engineers, Not Just Auditors

Our security reviews are conducted by network engineers with deep hands-on experience — not just compliance consultants running automated tools. We understand how your network actually works, which means we find the real risks.

Findings You Can Act On

Every audit produces a clear, prioritised report — critical findings first, with specific remediation steps for each issue. No vague recommendations, no consultant-speak. Just a practical roadmap to a more secure network.

We Can Fix It Too

Unlike auditors who hand over a report and disappear, AMROTS can implement the remediation ourselves. One team, full accountability — from audit to hardened network.

Our approach

How We Approach Network Security Audits

Through experienced startup consultants who understand the isolated tasks necessary, a client can rely on a professional to manage a critical step in the early stages and focus on other items that need attention.

Scoping & Discovery

Every audit begins with a thorough scoping exercise. We work with you to define the audit boundary — which devices, zones, and protocols are in scope — and gather existing documentation, firewall exports, and network diagrams. The more context we have upfront, the more thorough the audit.

Assessment & Analysis

Our engineers conduct a systematic review of your security posture — analysing firewall policies, ACLs, routing security, segmentation, and application-layer controls. We combine manual analysis with targeted testing to identify misconfigurations, policy gaps, and exposure points that automated tools routinely miss.

Reporting & Remediation

Every audit concludes with a detailed findings report — prioritised by severity, with a clear description of each issue, its potential impact, and specific remediation steps. We present the findings to your team, answer questions, and can implement the fixes ourselves if required.

The process

Our Security Audit Process

We provide the best services, ensuring your outstanding growth

Scoping & Information Gathering

We define the audit scope, gather existing documentation, and collect firewall policy exports, network diagrams, and any relevant compliance requirements. The more context we have, the more thorough the audit.

Assessment & Analysis

Our engineers conduct a systematic, manual review of your security posture — analysing firewall rulesets, ACLs, segmentation, RPKI, BGP session security, and application-layer controls across every device in scope.

Findings & Reporting

We produce a detailed, prioritised findings report — critical issues first, with specific remediation steps for each finding. We present the report to your team, walk through every issue, and answer questions clearly.

Remediation & Verification

Where required, we implement the remediation ourselves — hardening firewall policies, closing exposure points, and reconfiguring security controls. A post-remediation review confirms every finding has been addressed.

Frequently Asked Questions

Some frequently asked questions about the service that you may have questions about

Who are your typical clients for security audits?

We work with ISPs, carriers, enterprises, financial services companies, healthcare organisations, and any business where network security is critical. If your network carries sensitive data or supports mission-critical services, a professional security audit is worth doing.

What is the process for beginning a security audit?

It starts with a free consultation to scope the engagement. We'll discuss what's in scope, what documentation you have available, and what your key concerns are. From there we agree a clear Statement of Work and get started.

Do you only audit firewalls?

No — our security assessments cover the full network security stack, including firewalls, ACLs, routing security, BGP and RPKI, network segmentation, and application-layer controls. We assess wherever an attacker could gain a foothold or move laterally.

What if you find something serious during the audit?

We'll tell you immediately — we don't hold critical findings until the final report. If we find something that poses an immediate risk during the assessment, we flag it to you straight away so you can take action.

Can you implement the fixes as well as audit?

Yes — this is something we actively encourage. We can implement all remediation steps ourselves, ensuring the fixes are applied correctly and consistently. A post-remediation review confirms every finding has been addressed.

How do you handle sensitive network information during an audit?

All client data — firewall exports, network diagrams, IP plans, and findings — is handled with strict confidentiality. We are happy to sign NDAs before any engagement begins, and all audit materials are securely stored and deleted on completion.
