01
Scope and permissions
We agree the sites, addresses, devices and authority to test them. We define working hours, an emergency contact and systems excluded from testing.
Network audit
Business network audit
We check connections, devices and access rules in your company’s network. We review firewalls, Wi-Fi, VPN and internet-facing services. We identify problems and recommendations to discuss with your IT team.
Trusted by
Companies and institutions that need stable IT.
Do you know what connects to your network?
Networks grow with a business: new sites, devices, supplier access and rule exceptions accumulate. We review whether documentation matches the actual connections and whether access is limited to what is needed. We also examine separation between guest networks, users and important systems. The scope covers the specified sites and agreed connections to cloud services and the internet.
Work that may follow the audit
The report helps you decide whether you need configuration changes, stronger safeguards or more detailed testing.

TÜV NORD Polska has certified Virtline’s information security management system to PN-EN ISO/IEC 27001:2023-08. The published certificate states its scope and validity.

We plan tests with the people responsible for the network and its services. We do not attempt to disrupt operations without agreement.
02
Review and checks
We examine documentation, configurations, rules and selected connections. Additional scanning and active testing take place only within the agreed scope.
03
Analysis and report
We clarify results with administrators and describe confirmed problems. We document limitations and propose an order of work and ways to check the changes.
04
Discussion and further work
We deliver recommendations to the IT team and decision-makers. Implementation or retesting is agreed as a separate task.
Practical scope
What you receive after a network audit
Findings apply to the scope reviewed. We clearly identify connections and devices that could not be assessed.
A description of the segments, sites and important services checked. We identify discrepancies between documentation and configuration, and areas where information is missing.
Findings about firewall rules, VPN, Wi-Fi and administrator access. We describe unnecessary exposure, inconsistent settings and restrictions that are needed.
Assessment of available logs, alerts and configuration backups. We establish how administrators learn about problems and what information they have for restoring settings.
Recommendations with their rationale and effect on services. We distinguish simple corrections, work requiring agreed downtime and matters needing closer investigation.
Which test do you need?
A network review assesses connections, settings and management practices. Attempts to exploit vulnerabilities require additional scope and permission from the system owner. The report does not guarantee that every vulnerability has been found. We do not assume that a service user’s permission authorises testing a supplier’s or operator’s network.
Network audit questions
Can an audit cover several sites?
+
Yes. We agree the locations, connections between them, remote access and supplier responsibilities. Scope and pricing depend on devices, services and available access, not just the number of sites.
Do you need to visit our premises?
+
Some review work can be performed remotely using configurations and documentation. Checking equipment, physical connections or specific Wi-Fi issues may require a visit. We agree this before starting.
Will you disable the firewall or overload the network?
+
Not without a separate agreement. Before the review, we define permitted activities and safety conditions. Tests that could disrupt operations require a plan, appropriate permissions and an agreed time.
Can you help implement recommendations?
+
We can prepare and carry out agreed changes, such as firewall or VPN rules and network separation. Scope, costs, timing and rollback arrangements are agreed separately. Your current provider can also use the report.
Let’s agree your network review
Describe the number of sites, important services and reason for the audit. Include your deadline and who maintains the network. Confidential diagrams and configurations can be shared later through an agreed channel.
