One-time

One standard Linux instance

Root server, VPS or cloud instance

290 €net

Included in the fixed price

  • Review of access, patch level, services and firewall
  • Review of backup configuration and recent logs
  • Assessment of system condition and basic operational risks
  • Technical report with prioritized action plan
  • One-hour results call

Outside the basic price

For multiple systems, clusters, Windows servers, active security incidents or extensive platforms, we prepare a separate quote in advance. We only need credentials after the scope and price have been agreed.

The report is yours and can be used independently of any follow-up engagement.

Request a server audit

Linux server audit at a fixed price

The basic audit for one standard Linux instance costs a one-time €290 net fee. Briefly tell us the provider, number of systems and reason for the audit. We will contact you with the next steps and transparently agree any special requirements. Credentials are exchanged through a secure channel only after commissioning.

Please do not enter passwords, private keys or any other credentials.

Security check is loading.

We review the scope and usually reply within one business day.

Purpose

Establish a traceable technical baseline

The audit creates a reliable baseline before an operational takeover, an upgrade or the prioritization of technical measures. We review configuration and operating condition and document scope, findings and boundaries.

Suitable for

  • Taking over an existing Linux server
  • Preparing a major update or migration
  • Missing or outdated operations documentation
  • Unclear patch, backup or security status

Not included in the basic audit

  • Configuration changes or remediation
  • Penetration testing or evidence-preserving forensics
  • Backup restore testing
  • Full application or source-code audit
Scope

What the basic audit covers

This scope applies to one standard Linux instance and is confirmed before access. Different platforms or multiple systems are scoped separately.

Security & Hardening

  • Exposed ports and unnecessary services
  • Patch level, support status and known vulnerabilities
  • SSH, root and sudo configuration
  • Firewall rules and baseline hardening
  • Indicators of common compromise patterns

Backup configuration and evidence

  • Configured backup jobs and recent logs
  • Retention and offsite concept
  • Configured encryption
  • Boundary: no restore test in the basic audit

System Health

  • Disk condition and file systems
  • Storage utilization, inodes and resources
  • System and service errors in logs
  • Database reachability and baseline configuration

Technical report with prioritized measures

The report separates observations, risks and recommendations. During the results call, we discuss priorities, dependencies and possible next steps.

Findings overview

The reviewed areas, identified deviations and their technical urgency are documented in a traceable format.

Action plan

Recommended measures are prioritized by risk, dependencies and a practical implementation order.

Results review

We review the report in a one-hour call. Remediation or ongoing operations can then be commissioned separately.

Illustrative example

What an audit typically surfaces

Each finding separates the observation, technical impact and recommended action. The examples below are anonymized patterns showing both the report format and the range of what surfaces on a system left unattended for a while.

Finding SEC-04

High

Password authentication for SSH remains enabled

Observation
Administrative SSH access accepts passwords in addition to key-based authentication.
Impact
The externally reachable login increases exposure to automated authentication attempts.
Recommendation
Verify existing keys and emergency access, then disable password authentication and document the change.

Finding SYS-02

High

Operating system no longer receiving security updates

Observation
The installed distribution has passed its end of vendor support. Security updates are no longer published for this version.
Impact
Newly disclosed vulnerabilities in the kernel and system libraries stay open permanently. Updating individual packages does not close them.
Recommendation
Define and schedule a migration path to a supported version; restrict reachable services until then.

Finding NET-01

High

Database service reachable from the internet

Observation
The database service listens on all network interfaces and is reachable from the internet.
Impact
The service is directly exposed to automated scans and login attempts, with no upstream access control in between.
Recommendation
Bind to the local interface or restrict access to known sources; route application access over the internal network.

Finding BAK-03

High

Backup stored on the same system

Observation
The configured backup writes to a directory on the same server. No copy outside the system is set up.
Impact
If the storage fails or the system is encrypted, the backup is affected as well. It is unavailable precisely when it is needed.
Recommendation
Set up a target outside the system and restrict write access to it from the server.

Finding ACC-05

Medium

Administrative accounts without an owner

Observation
Several accounts with sudo privileges had not logged in for an extended period. They could not consistently be mapped to people currently involved.
Impact
Access nobody owns is overlooked when staff change and simply remains in place.
Recommendation
Map accounts to current owners, disable those that cannot be mapped, and document the assignment.

Finding FW-02

Medium

No packet filter active

Observation
No packet filter ruleset is active on the system. Network access is limited solely by which interface a service binds to.
Impact
A service that binds publicly after an update or misconfiguration is immediately reachable. There is no second layer to catch it.
Recommendation
Set up a baseline ruleset that only opens required ports, and document its state.

Which of these apply to your system is not known in advance — that is precisely the question the audit answers. If the report contains no finding for which we recommend a measure, we do not invoice it.

After the audit

A finding is only worth something once someone can act on it

Many audit reports end with a list and the question of who implements it. We work on all three levels a finding can land on - and say openly in the results call which of them you actually need.

Secure

When the finding concerns access, patch level or exposed services.

  • Hardening of SSH, firewall and services
  • Remote access through NetBird instead of open ports - we are an official NetBird reseller
  • MFA through your identity provider, not a second user database
  • CVE monitoring against NVD, CISA KEV, CERT-Bund and BSI
See CVE monitoring

Operate

When the finding shows that nobody looks regularly.

  • Server operations from €149.90 per month - patching, backup management, monitoring and incident response
  • Monitoring only from €79.90 per month, if operations stay with you
  • For Hetzner, IONOS, OVH, netcup, AWS, Azure and your own hardware
  • Server and contract stay in your account - we take on the operations, not the ownership
See server operations

Modernize

When the server no longer has the right home.

  • Migration from VMware or Hyper-V to Proxmox
  • Moving out of AWS, Azure or GCP to European providers
  • Managed Proxmox from €179.90 per node per month
  • On-premises, when data must not leave the building
See migration paths

The audit obliges you to none of this. The report is yours and may be shared internally or with another provider.

Frequently Asked Questions

Details on scope, access, results and boundaries

Topics

Process & Security

No planned shutdown is required for the basic audit. The review is predominantly read-only during live operation; load tests and configuration changes are not included. We agree any special risks or necessary exceptions in advance.

We generally require time-limited SSH access using a public key and the sudo permissions needed for the agreed scope. Database access or additional permissions are agreed only when required for the review.

Credentials are not sent by unencrypted email. We agree an appropriate transfer method, such as an encrypted one-time secret link. Temporary accounts and keys should be disabled or revoked after completion.

A non-disclosure agreement can be concluded before work begins. Where required for the specific access, we additionally agree a data processing agreement.

After completion, we remove the audit credentials stored in our working systems. The customer revokes temporary accounts and keys, or they are transferred into a controlled operating scope if ongoing operations are commissioned.

Scope & Technology

We review common Linux distributions such as Ubuntu, Debian, AlmaLinux, Rocky Linux and SUSE/SLES. For unsupported versions, the focus is on risk, migration feasibility and a suitable upgrade path.

Yes. We check both 'bare' Linux servers and systems managed with panels like Plesk, cPanel, LiveConfig or CloudPanel. We specifically check whether the panel itself is securely configured and whether updates are pending.

The basic audit can identify indicators of common compromise patterns, unusual processes or suspicious persistence mechanisms. It does not replace evidence-preserving incident response or a forensic investigation. If there is a concrete suspicion, we define a separate scope.

Yes. We check MySQL/MariaDB and PostgreSQL for obvious misconfigurations (e.g. open ports to the outside, default passwords, missing backups). However, we don't do performance tuning of individual SQL queries (that would be application-level).

The basic audit reviews backup configuration, retention and recent job logs. An actual restore test is not included and can be commissioned separately with a suitable target system and agreed procedure.

Results & Costs

The fixed price applies to one independently reviewable physical or virtual Linux server running common system, web, database or container services. Clusters, orchestration platforms, multiple coupled systems and environments with an active incident concern receive a separate scope in advance.

No. The basic audit is an assessment without configuration changes. If required, we define a separate scope and quote for suitable remediation measures or an operational takeover.

€290 net is the one-time flat rate for the described basic audit of one standard Linux instance. It does not create an ongoing management service. Clusters, extensive platforms or additional systems are scoped separately in advance.

Then we do not invoice the basic audit. The report is the criterion: if it contains no finding for which we recommend a measure, the fee is waived. In practice this rarely happens - on a system nobody has reviewed for a while, there are almost always items that need attention.

If a finding requires short-term action in our technical assessment, we contact you through the agreed channel before the report is complete. System changes require approval or a separately agreed incident scope.

Yes. After the audit, the system state, risks, and recommended measures are documented. On that basis, we can offer a clearly defined operating scope for updates, monitoring, backup management, and support.

Yes. You receive the technical report and prioritized action plan regardless of whether WZ-IT subsequently performs remediation or takes over operations. The report can be used internally or with another service provider.

The basic audit described here applies to Linux servers. Windows Server, Active Directory, Exchange and comparable Microsoft environments are outside this offer.

Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated)
