The $29/month alternative to a six-figure SIEM

With new attack vectors, zero-day exploits, and nation-state sponsored threat actors making headlines every week, the question every IT team faces isn't if they'll be targeted — it's whether they'll know when it happens. The cybersecurity adage "prevention is ideal, but detection is a must" has never been more relevant.

So you start looking at detection tools. Splunk Enterprise runs $1,800+ per year per GB of daily ingestion. IBM QRadar starts around $800/month for basic deployments. Microsoft Sentinel charges per GB of log data ingested into Azure. Elastic SIEM is open source but requires dedicated infrastructure to run. LogRhythm, Securonix, Exabeam — all assume enterprise budgets and dedicated security staff to configure and maintain them. You look at the pricing, look at your team of two, and close the tab.

But the need doesn't go away. You still need to be able to see what's happening on your network. You need detection — not next quarter when the budget allows it, but now, on the machines you're already managing. That's where Arden comes in: a simple, affordable, portable solution that gives you direct insight into Windows event logs without the infrastructure, the cloud dependency, or the six-figure price tag.

What you actually need vs. what they're selling you

Enterprise SIEMs do three things: collect logs, run detection rules, and show you a dashboard. For that, you're paying for log ingestion by the gigabyte, agents on every endpoint, a cloud subscription, and usually a professional services engagement to configure it. Most SMBs end up paying $500 to $5,000 per month and still have rules they never tuned and alerts they never check.

What if you could get the detection part — the part that actually finds attacks — without the infrastructure? That's the idea behind Arden. It's a single Windows executable that reads your event logs directly, runs detection rules covering the full MITRE ATT&CK kill chain, and serves a real-time dashboard on localhost. No server. No database. No cloud. No agents (unless you want them for multi-host monitoring).

What $29/month gets you

The Standalone tier runs on a single machine and analyzes its local event logs. In 30 seconds, you go from "I have no idea what's happening on this machine" to a prioritized list of security findings sorted by severity, mapped to MITRE ATT&CK, with contextual explanations of what each alert means and what to do about it. You can import EVTX files from other machines, export findings as CSV or JSON for your records, and suppress false positives so they don't clutter future scans.

For $49/month, the Network tier adds the ability to deploy lightweight agents to every Windows machine on your network, scan your network for hosts, collect logs remotely via admin share or WinRM, and monitor everything from a single dashboard. It's the same detection engine — you're just running it across more machines.

Is it a replacement for CrowdStrike or Sentinel? No. Those tools do real-time endpoint protection, cloud telemetry, and managed threat hunting. But if your alternative is nothing — which is the reality for most SMBs — then detection rules running on your actual logs is infinitely better than hoping your antivirus catches everything.
