Pass the audit — and mean it.
We help companies meet KVKK and ISO 27001 with security that would actually stop an attacker — not a binder of policies. Real logging, monitoring, and detection, built on open-source tools you own and keep.
Independent & hands-on · fixed-scope assessments · you keep the stack
Compliant on paper isn't the same as secure
Most compliance projects produce paperwork that passes the audit and protects no one. Then a breach hits — and the gap between "compliant" and "secure" gets expensive fast, including a 72-hour KVKK breach notification you're not ready for. We close that gap with monitoring that's real, not theatre.
What we do
Four things, done hands-on. We don't subcontract, and we don't resell software licenses.
Compliance & security assessment
Where you stand against KVKK / ISO 27001, which logs and monitoring you're missing, and the shortest path to closing the gap. Fixed scope, fixed price.
Open-source security build
We deploy and tune the technical controls — logging, monitoring, file integrity, detection — on Wazuh, Security Onion, Zeek/Suricata and OpenSearch, configured to your environment and documented.
Detection engineering
Detections mapped to real threats and to your control set, tested against real telemetry and tuned to kill the noise — so monitoring means something, not just a checkbox.
Incident response
Hands-on help during and after an incident — triage, containment, forensics, a clear timeline, and the evidence and notifications KVKK and ISO 27001 require.
Data loss prevention (DLP)
Most requestedYour data shouldn't leave the company unnoticed. We make where sensitive data goes visible — and block the exits that matter. Built on open source, so the monitoring and the evidence stay yours.
- Network egress monitoring (Zeek/Suricata) with hard blocks at the firewall
- USB & removable-media control and copy detection (Wazuh/auditd)
- Alerts on personal-cloud uploads and unusual data flows
- Evidence for GDPR Art. 32 / KVKK Article 12 technical measures
Why open source
Enterprise-grade security without the enterprise lock-in.
You own it
No license to renew, no vendor between you and your own data. The stack stays when we leave.
Audit-ready evidence
Real logs, real alerts, real retention — exactly what an ISO 27001 auditor and the KVKK technical measures expect to see.
SMB-affordable
Enterprise-grade monitoring without the enterprise SIEM invoice.
Selling to Europe? There's a compliance wall first.
European partners treat every supplier as a risk. Before they sign, they want proof your data stays protected — technical measures, not promises. We help you clear that bar on open source you own.
GDPR
Mandatory if you process EU personal data. Needs a data-processing agreement and a valid transfer basis (SCC / adequacy, post-Schrems II).
ISO 27001 / 27701
The information-security and privacy certifications EU customers ask their suppliers to hold.
NIS2
In force since 2024. If you supply essential or important sectors, its cybersecurity duties reach you too.
DORA
Digital operational resilience for anyone working with the EU financial sector.
SOC 2
Frequently requested by SaaS and technology buyers as assurance of your controls.
Data residency & transfer
Where data lives and how it crosses borders — designed in with evidence, not bolted on later.
How we work
We take work we can do well, and we leave you able to run it.
Assess
Understand your environment, map the gap to KVKK/ISO 27001, and agree the scope. Fast and fixed-price.
Build
Deploy and tune the open-source controls. Detections mapped to threats and to your control set. Evidence an auditor will accept.
Hand over
Documentation, runbooks, and a walkthrough so your team owns it. Optional retainer for tuning and incident support.
Built on open source
The tools we deploy and operate — each tied to a control, not a logo on a slide.
Questions
Do you also write the ISO 27001 documentation?
I focus on the technical controls and the evidence behind them — logging, monitoring, detection, incident response. I work alongside your auditor or documentation consultant and make sure what's on paper is actually true in your systems.
Isn't open source riskier than a commercial SIEM?
The software isn't the risk — the tuning is. A default install of any tool is noisy and useless. What you're paying me for is judgment: making these tools quiet, correct, and mapped to your controls. And unlike a commercial SIEM, you keep everything.
I have an audit coming up. Can you help in time?
Tell us the deadline in your first message. The assessment is fast and fixed-scope, so we'll know quickly what's realistic before the audit and what needs a remediation plan.
What happens when the engagement ends?
You own the stack and the documentation. We hand it over with runbooks and a walkthrough so your team can run it. An optional retainer is available for tuning and incident support — but you're never locked in.
About
Munio Defense is a blue team practice. We build and run defensive security operations — monitoring, detection, and incident response — entirely on open-source tools, so you get real protection and the audit evidence KVKK and ISO 27001 require, without vendor lock-in.
No black boxes and no proprietary agents — just well-tuned open-source tooling you own and can run yourself. We publish Field Notes on the detection work as we go.
Principles: ownership over lock-in · evidence over paperwork · you keep the stack.
