01
Servers and working conditions
We agree the server list, roles, responsible people, access and maintenance windows. We identify particularly sensitive systems and test exclusions.
Server audit
Server security audit
We review the configuration and security of Windows and Linux servers. We assess administrator access, updates, backups and monitoring. The report explains what needs improving and the recommended order of work.
Trusted by
Companies and institutions that need stable IT.
Are your servers ready for failure and unauthorised access?
A working server and its services do not by themselves confirm that security controls are correct. We review agreed servers, authentication, updates and dependencies. We check whether logs help identify failures or unauthorised access and whether service recovery is supported. The scope can include physical servers, virtual machines and virtualisation hosts.
Services connected with your servers
Some findings require work beyond the operating system itself. We recommend further work based on confirmed findings.
Network audit
Checking connections, internet-facing services and separation between user, server and backup traffic.Backup and recovery
Backup design, storage arrangements and tests of data recovery and service restoration.Multi-factor authentication
Additional sign-in protection for services that support it, with a scope agreed with administrators.IT monitoring
Monitoring system availability and health, notifications and agreed arrangements for handling alerts.ISO 27001 · TÜV NORD Polska
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.

Before the review, we identify critical systems and agree what to do if a check could disrupt a service.
02
Configuration review
We examine agreed settings, reports, accounts and services. We verify tool output in the context of the system; additional scans or intensive tests require agreement.
03
Report and priorities
We describe the problems, how they were checked and our recommendations. We explain review limitations and changes that need consultation with the application owner.
04
Discussion and follow-up
We deliver the report to administrators and decision-makers. Implementation and rechecking selected findings can be commissioned under a separate scope.
Practical scope
What the server report covers
We relate each finding to the system reviewed and its role in your business, not just to a tool’s output.
Roles, services, unnecessary functions, connection settings and available updates. We identify the versions checked and limitations such as application requirements that constrain updates.
Administrator practices, service accounts and remote sign-in. We check excessive access, whether changes can be traced and how permissions are withdrawn.
Backup coverage, available restore-test results, event records and notifications. If a restore test was not part of the engagement, we do not present it as a test we performed.
Proposed changes with priorities and dependencies. We identify work that requires downtime, further checks or involvement from the application provider.
Changes after the audit
An audit does not authorise production updates, service shutdowns or permission changes. Such work requires agreement, an impact assessment and recovery arrangements. A review does not replace a full penetration test or post-incident investigation, nor does it establish the absence of all vulnerabilities.
Server audit questions
Do you need administrator accounts?
+
Some information can be collected with read-only permissions or with an administrator’s help. For deeper checks, we agree the access required and how it will be protected. We do not ask you to send passwords through the form.
Do you review Windows and Linux servers?
+
Yes. We tailor the scope to specific systems and services, such as file, web, mail, database and virtualisation services. We agree the versions, components and exclusions before starting.
Does the review require downtime?
+
Many checks can be performed without shutting down services. However, we do not assume every test has no operational impact. Tests that could place a load on a system or require a restart are agreed separately and planned with the administrator.
Can you check whether fixes are effective?
+
We can agree a follow-up review of selected problems after changes have been implemented. Its scope and timing are agreed separately. We provide the results of checks, not merely confirmation that someone says a recommendation was implemented.
Tell us about your servers
Include the server count, operating systems and main applications. Describe the purpose of the review and your preferred deadline. Do not send passwords or confidential configurations through the form.
