Arden reads the event logs your Windows servers and PCs already keep and alerts you to signs of an attack, such as stolen credentials, lateral movement and cleared logs. It can also show auditors which logging their HIPAA, PCI DSS, CMMC or CJIS requirements depend on. It runs on your own server, and your logs stay on your network.
Checks Windows event logs as they arrive and alerts on lateral movement, credential theft, persistence and privilege escalation. Each rule is mapped to MITRE ATT&CK.
Maps Windows event activity to 133 requirements in seven frameworks, so you can see which of the logging auditors ask about is in place and which isn't.
Includes everything in Arden Security and Arden Comply. Alerts and logging evidence sit in the same dashboard, which helps when an incident turns into an audit question.
Arden's rules cover common Windows attack techniques across eight MITRE ATT&CK tactics, from password theft to the steps attackers take before deploying ransomware. Routine Windows activity is filtered out before an alert is raised.
We test each build against EVTX-ATTACK-SAMPLES, a public collection of 278 recorded attacks. The current build raises at least one alert on 233 of them (84%). About half of the rest leave no trace in the logs Arden collects, which is why we say Arden detects many attacks, not all of them.
Run the Arden executable on a Windows server you control. There is nothing else to install, and the dashboard opens in your browser.
Scan your network from the dashboard and deploy the Arden agent to the servers and PCs you pick. Agents send event logs to your Arden server and nowhere else.
Alerts appear in the dashboard and can be sent by email or webhook. Audit-log coverage reports export to PDF, CSV and JSON.
A service named PSEXESVC was installed on FILESRV01 at 2:14 AM. PsExec and similar tools install a service like this to run commands on a machine remotely, and attackers use them to move from one machine to the next. If your admins use PsExec, you can suppress this alert for that use. If not, find out who ran it and from where.

Two of the most accessible security monitoring options for small teams disappeared in the last eight months. Here’s what changed, and where Arden fits.
Per-GB pricing is just the start. Overage charges, tuning labor, analyst salaries, and compliance mandates make traditional SIEMs 2–3x more expensive than the quote — and hit hardest at the SMBs that can’t opt out.
EDR misses 79% of today’s attacks because they’re malware-free. RDP abuse appears in 90% of ransomware cases. A flat-rate SIEM on your servers closes the gap most teams don’t know they have.
HIPAA, PCI DSS, CMMC, CJIS — they all require log monitoring. Here’s how Arden Comply maps Windows events to framework controls and generates PDF reports to help organize your evidence.
Splunk, QRadar, Sentinel, and Elastic — what they actually cost for a 50-endpoint Windows shop. Plus why per-GB billing punishes small teams, and the flat-rate alternative.
After landing on a machine, attackers dump LSASS to steal credentials. Here's how to catch Mimikatz, comsvcs.dll, ProcDump, and registry SAM extraction using native Windows events.
Enterprise security tools assume enterprise budgets. Here's how small IT teams can get real threat detection coverage with native Windows logs, open rules, and a single executable.
When an attacker lands on one machine, they move to others. Here's how to read the trail they leave in Windows event logs — PsExec, WMI, RDP, and pass-the-hash artifacts explained.
You don't need a SIEM to catch the most common attacks. These five event IDs cover brute force, lateral movement, privilege escalation, and credential theft — and they're already in your logs.
Arden is in invite-only beta. Leave your work email and we'll contact you about a two-week beta license. Beta testers get a discount on their first year.

Named after the Ardennes — the forested region where Allied defenders held the line against a massive offensive in the winter of 1944. Arden won't stop an attacker on its own, but it can show you what happened, how far they got and where to look next.
