I will write custom wazuh decoders and detection rules for your log sources
Wazuh SIEM Deployment and SOAR Automation Engineer
About this Gig
Wazuh's default ruleset doesn't know your firewall, EDR platform, hypervisor, or custom app logs, so those events get dropped as unparsed or matched incorrectly. I write decoders and rules that make Wazuh understand your log sources, tested against real samples before delivery, not shipped blind.
I do this as part of my day-to-day SOC work, building detection content for the exact devices most generic deployments skip.
What you get: 8+ device types covered, firewalls, EDR platforms, hypervisors, network gear parsed correctly instead of dropped as unknown. Zero alert noise, rules tuned against real samples so you get signal, not false positives. Documented patterns for fast onboarding of new log sources. Tested before delivery against your actual samples, confirmed parsing and alerting.
Who this is for: teams running Wazuh that keep seeing unknown or unparsed events, anyone needing detection coverage for an unsupported device, and MSPs standardizing decoder patterns across clients.

FAQ
What do you need from me to write the decoder?
Real (or realistic, redacted) sample log lines from the device — at least 5-10 examples covering the event types you care about. Without real samples I can't guarantee accurate parsing.
What if my log source is unusual or undocumented?
Send samples and a brief description of the device/software — most formats (syslog, JSON, key-value, CEF) are workable. I'll confirm feasibility before you place the order.
Will this cause false positives on my existing setup?
Rules are tuned against your provided samples specifically to avoid this, and Standard/Premium include a dedicated noise-tuning pass.
Can you also enable active response (auto-block, auto-isolate)?
Yes, available as an add-on or included at Premium — tell me which rules should trigger an automated response.
