Calculate pentest and audit costs based on scope, criticality and compliance requirements.
Security audit cost calculator
The Security Audit cost calculator provides an immediate, non-binding cost range without requiring an email address or registration. It combines your project inputs with documented calculation rules and experience from more than 250 software projects.
Use the calculator right below for an instant first estimate – no sign-up and no fixed-price commitment. We align scope, risks, and assumptions in a conversation before a binding quote.
The calculation follows six visible stages. All figures remain planning values until scope and assumptions have been reviewed.
1. Capture inputs
The calculator records the visible project, volume, complexity and operating parameters selected on this page.
2. Add fixed components
Fixed base modules and selected add-ons are added without mixing them with recurring charges.
3. Apply multipliers
Quantity, complexity and scope factors multiply only the cost components identified for them in the calculator model.
4. Create the range
The calculator applies its documented lower and upper uncertainty factors to the base result; ROI views keep investment and savings visible separately.
5. Round and calibrate
Monetary result fields are rounded to the nearest whole euro. Public project-cost components are calibrated with the centrally maintained display factor.
6. Classify the result
The result is shown as non-binding guidance. A binding quote requires scope, data, integrations, risks and acceptance criteria to be reviewed.
Efficiency or discount factor: A central display factor of 0.7 is applied to public project-cost components to keep all calculators aligned with the currently reviewed pricing basis. It is not a customer-specific discount; customer-entered wages, revenues and existing operating costs are not reduced.
Why this is not a binding quote: The calculator cannot verify complete requirements, third-party dependencies, data quality, legal constraints or acceptance criteria.
Security audit costs vary with scope, depth, and remediation support.

FAQ
Quick checks prioritise obvious attack paths with lighter reporting, while comprehensive programmes blend interviews, configuration reviews and deeper testing cycles.
Red-team exercises add scenario design and longer observation windows.
Each framework expects specific evidence—GDPR processing records, ISO control mappings, NIS2 governance artefacts.
Aligning documentation consumes senior time even before technical testing starts.
Yes for anything rated high or critical.
Without verification you only have a hypothesis that the vulnerability disappeared.
It shortens chaos during real breaches and clarifies legal, comms and technical steps—saving far more than its authoring cost when minutes matter.
A pentest actively probes the application for exploitable weaknesses, such as broken access controls or injection flaws.
The effort depends on the number of applications, attack surfaces and desired depth. In the calculator you can distinguish a one-off test from recurring assessments.
Requirements such as GDPR or industry-specific standards expand the scope to include documentation, processes and evidence beyond pure technology.
This increases effort but creates legal certainty. We recommend clarifying the compliance framework early so the audit stays focused.
A re-test confirms that the reported weaknesses were actually closed and no new ones appeared.
Without it, the effectiveness of the measures stays unproven. In our experience you should plan the re-test from the start, because it is an integral part of a credible audit.
For actively developed software, an annual review or an audit after major releases is a good benchmark.
Static systems can tolerate longer intervals. In the cost calculator the difference between a one-off and a recurring assessment is easy to represent.
Automated scans find known, surface-level weaknesses quickly and cheaply but miss logic flaws and complex attack chains.
A manual audit uncovers exactly these deeper risks. A combination is usually most economical, tuned to the criticality of the application.
You receive a prioritised report with the weaknesses found, a risk assessment and concrete recommendations for action.
From this a clear action plan can be derived. This traceability is crucial so the invested budget delivers measurable security gains.
Scope, technical review, report, and re-check—so you know what your audit investment delivers.
1. Scope and protection-needs capture
We clarify which systems, interfaces, and data are reviewed. From that emerges a serious calculation.
2. Technical review
We calculate pentest, code review, configuration check, and optionally social engineering tests individually.
3. Report with actions
We deliver an audit report with prioritization. You pay for actionable insights, not for a checklist.
4. Re-check
After your implementation we re-check—fixed price. So the security gain is also provable.
| Model | When it fits | Budget & flexibility | Typical risks |
|---|---|---|---|
| Fixed price (fixed scope) | Clearly defined scope, stable requirements, repeatable delivery. | Predictable total cost; little room for change without a change order. | Scope creep leads to change orders or quality trade-offs. |
| Time & Material | Discovery, legacy, evolving requirements, or close collaboration. | Maximum flexibility; budget transparent via hourly or daily rates. | Without prioritisation, effort can grow—backlog and reviews matter. |
| Retainer / maintenance package | Ongoing operations, updates, small features, and support. | Agreed capacity per month; predictable follow-on cost. | Large changes may still need a separate estimate. |
| Hybrid (milestone + T&M) | MVP or phased releases with clear go-lives, then iterate. | Core delivery fixed price; extensions on a time-and-materials basis. | Define contractually what is in scope vs. extra work. |
Calculators on this page provide indicative ranges; we choose the right model with you based on risk, scope, and planning horizon.
The ranges shown are indicative. For a binding quote we discuss scope, priorities and funding options in a free intro call. Many digitalization projects qualify for grants – try our funding calculator.
