Security Auditing and Infrastructure Review
Most security gaps are not unknown — they are just unseen. Companies that have not had an infrastructure review in years often discover open ports, outdated firmware, employees with excessive privileges, and segmentation that was never properly implemented. An audit is not a punishment — it is the answer to the question "where are we, and what should be fixed."
Codex Media conducts security reviews with CCIE-level understanding of network and security systems. The result is not a theoretical report but concrete, actionable recommendations ordered by priority — with a clear explanation of each risk and how to remediate it.
What it includes
- network topology and active device analysis
- review of router, switch and firewall configurations
- access control and user privilege check
- identification of exposed services and open ports
- network segmentation and isolation review
- VPN configuration and access policy analysis
- firmware and software version assessment
- prioritized findings report with remediation recommendations
What it means in practice
- you know where the weak points are — no guessing
- clear understanding of which risks are real and which are critical
- an ordered remediation plan with effort estimates
- informed decision-making on investment priorities
- a solid starting point for building a long-term security strategy
Typical scenarios
Company with no recent review
Infrastructure has grown organically — switch by switch, rule by rule. No one actually knows what exists, who has access to what, or what is exposed to the internet. An audit delivers a clear picture and identifies what is urgent versus what can wait.
Preparing for regulatory compliance
The company needs to satisfy GDPR, NIS2, or ISO 27001 requirements. The audit identifies the current state and gaps that need to be closed — with concrete recommendations that are acceptable within the regulatory context.
After an acquisition or merger
You have acquired another company or merged with a partner. You are not sure what you have inherited in terms of IT infrastructure and security posture. The audit gives a clear picture of the inherited environment and identifies risks to remediate before integration.
Problems it solves
- unknown security posture of the infrastructure
- outdated or inconsistent device configurations
- overly broad access for users and systems
- weak or missing network segmentation
- open services and ports exposed to the internet
- no clear accountability for access management
- unfulfilled regulatory obligations
How we approach auditing
We conduct the review without aggressive penetration testing in the production environment — the focus is on analysis of configurations, topology, policies and exposed services, combined with interviews with the people responsible for IT.
We deliver a structured report with findings ordered by criticality, clear risk explanations, and concrete remediation recommendations — without buzzwords and without scaremongering.
Frequently asked questions
Is a security audit the same as a penetration test?
They are not the same. A penetration test actively attempts to breach the system, simulating an attacker. The security audit we conduct is a review and analysis — of topology, configurations, policies and access — without aggressive testing in the production environment. For most companies, an audit is the better starting point because it establishes a clear picture before going into deeper testing.
How long does an audit take?
For a typical single-site business — data collection and analysis usually 2 to 5 working days, depending on the size and complexity of the infrastructure. Report delivery with recommendations within one week of completing the review. All without disrupting production operations.
Will an audit reveal that everything is broken and needs to be replaced?
An audit reveals the real state — which is rarely "everything is broken" or "everything is perfect." There are almost always things that work well and specific weaknesses that need addressing. Recommendations are always prioritized and account for realistic operational capabilities — not an unrealistic list of 200 tasks that no one can execute.
Who is an audit for?
Everyone who wants to know where they stand in terms of security — regardless of company size. Especially relevant for companies that are growing, planning new system deployments, have regulatory obligations, or have recently experienced suspicious activity. A good audit is also the starting point for organizations planning to implement network security or SD-WAN solutions.
What do I get at the end of the audit?
A structured report containing: a summary of analyzed components, findings ordered by criticality (critical, high, medium, low), clear risk explanations, and remediation recommendations. We also hold a findings review meeting where you can ask all questions and together define priorities for next steps.
Can you also implement the fixes after the audit?
Yes. The audit can be the beginning of a longer engagement — after the review we can take on the implementation of recommendations, or you can use the report as a basis for your internal IT team. Both options are valid — our goal is to give you useful information, not to create dependency.
