Security audit costs for measurable risk reduction
Typical price range
EUR 8,000-180,000 excl. VAT
Typical duration
2-12 weeks depending on scope and retest effort
Main risk drivers
- - Overly broad audit scope without critical-asset prioritization
- - No remediation planning after findings
- - Compliance requirements addressed too late
FAQ
Security audit costs
Scope & pricing
How do quick checks differ from comprehensive audits?
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.
Why do compliance selections move the estimate?
Each framework expects specific evidence—GDPR processing records, ISO control mappings, NIS2 governance artefacts. Aligning documentation consumes senior time even before technical testing starts.
Remediation & retest
Should we schedule retests?
Yes for anything rated high or critical. Without verification you only have a hypothesis that the vulnerability disappeared.
What value does an incident response plan add?
It shortens chaos during real breaches and clarifies legal, comms and technical steps—saving far more than its authoring cost when minutes matter.
Calculator, follow-up costs & next steps
What does security audits typically cost in a mid-market scenario?
The Security Audit Calculator provides a realistic initial range. The strongest drivers are audit scope (pentest, architecture, compliance).
What does security audits cost with aggressive timeline and multiple integrations?
In that setup, both delivery effort and risk buffering increase. Key impacts usually come from number of systems, criticality and re-test effort.
Which follow-up costs are often underestimated for security audits?
Typical follow-up costs include operations, monitoring, maintenance, change requests and additional integrations after the initial rollout.
Which risks impact budget and timeline the most?
The biggest risks are unclear requirements, dependencies on third-party systems, data quality issues and late scope changes.
Can I use this estimate for internal budgeting?
Yes. The range is built for management-level planning and is refined into milestones and budget blocks in a short discovery call.
What is the next practical step after the Security Audit Calculator?
We review your inputs, prioritize open points and provide a concrete implementation path. Recommendation: prioritize findings and tie them to a remediation roadmap.
Typical pricing models (overview)
| 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. |
