Alright, I'm usually hanging out in the BI forums, but my startup is finally taking security seriously and I've been tasked with evaluating EDR options. My data's on lock, but our endpoints? Not so much.
We're under 50 seats, and the budget is, well, startup-sized. I've been digging into the free/low-cost tier offerings, and it's a mixed bag. I'm looking for something that gives decent visibility and doesn't just rely on signature-based detection.
Here’s my shortlist from initial research:
* **Wazuh**: Open-source, which is great for cost. Seems powerful but the DIY overhead for deployment and tuning looks non-trivial. Feels more like a SIEM+EDR combo.
* **Elastic Security (ELK Stack)**: Also open-core. Powerful if you're already in their ecosystem, but the learning curve is steep. I'm comfortable with queries, but YAML configurations for agents at scale give me pause.
* **CrowdStrike Falcon** / **SentinelOne** free trials: The 15-day trials are full-featured, but that's just a evaluation window, not a solution.
* **Microsoft Defender for Business**: Bundled with some M365 plans. Seems like the most integrated path if you're already in their universe. The pricing gets murky fast though.
My core needs:
1. Centralized alerting (a clean dashboard I can check without SSH-ing into a server).
2. Some capability for threat hunting (being able to write simple queries against endpoint data).
3. Low maintenance overhead. I'm a team of one for data *and* infra right now.
Has anyone actually deployed and managed something like Wazuh at this scale? How much ongoing tuning does it require? Or is a managed, low-cost commercial option actually worth the per-endpoint fee for the time savings?
I'm curious about real-world operational experience, not just feature lists. Bonus points if the solution has a decent API so I can pull alert data into my own dashboards later 😉.

Data is the new oil - but it's usually crude.
I'm a senior data engineer at a 75-person fintech, and we've been running EDR across our developer workstations and cloud servers for about three years now, alongside our main Kafka and Postgres stack.
* **Deployment & Ongoing Tuning Effort**: Wazuh's all-or-nothing. If you're comfortable managing your own index templates, agent groups, and decoders via Ansible, it's free. The initial setup for 50 endpoints is a 2-3 day project. Elastic is similar, but if you're already on their stack for logging, the agent (Elastic Agent) integration is cleaner, though you'll still lose a week tuning detection rules.
* **Actual Cost for Under 50 Endpoints**: Wazuh and Elastic's core security features are free. The real cost is 10-15 hours a month of maintenance unless you containerize everything. Defender for Business runs about $4-8/user/month if you need the standalone SKU, but it's often already licensed in M365 Business Premium. CrowdStrike and SentinelOne start around $12-18/endpoint/month even for startups once the trial ends.
* **Detection Depth & Noise Floor**: The open-source rulesets are noisy. You'll get a flood of alerts on day one. Wazuh's default malware detection is primarily signature-based; you need to integrate VirusTotal or YARA for behavioral stuff. Elastic's prebuilt detection rules are better but still require you to tune the threshold and exclude your dev tools.
* **Integration & Data Sovereignty**: Wazuh and Elastic dump everything into your own infrastructure. That's a win for cost control and pipeline integration - I pipe alerts to a dedicated Kafka topic. Cloud solutions like Defender and CrowdStrike are opaque boxes; you get their portal and limited API access. If you need to feed events into a data lake, that's a hard stop.
For your size and stated budget, the only sane answer is Microsoft Defender for Business if you're already on M365 Business Premium. If you're not, then you're choosing between spending cash (Defender) or spending engineering time (Wazuh). Tell us if you have a dedicated infra person to babysit it and whether you need to ingest the raw alert stream into your own monitoring.
Good list to start with, and you've nailed the core trade-off: upfront cash vs. ongoing time. Since you're coming from BI, the YAML/config overhead for Elastic or Wazuh might feel heavier than you expect.
You mentioned **Microsoft Defender for Business**. If you're on Microsoft 365 Business Premium, it's included, and the integration is genuinely seamless. The murky pricing usually applies if you're on a lower tier. The catch? Its detection logic can be a bit opaque compared to the open-source options.
Have you looked at the free tier of **Sophos Home** for business? It's surprisingly full-featured for under 50 endpoints and manages a lot of that tuning overhead for you. Not as deep as Wazuh, but way less hands-on.
