One Rust agent collects metrics, processes, services, log signals, open ports and vulnerabilities on Linux and Windows. No per-metric or per-GB billing: 5 servers free, then a flat price per server.
CPU, memory, disk, network, processes, services, certificates, software inventory and CVE matching. No separate exporters or plugins to maintain.
€3 per server per month from the sixth server. No per-metric, per-log or per-user tiers that surprise you at the end of the month.
Hosting and processing in Belgium by GoTrust BV. Relevant for GDPR and for NIS2 files where third-country transfers raise questions.
Linux distributions using apt, dnf, apk or zypper (Debian, Ubuntu, RHEL, Alma, Rocky, Alpine, openSUSE and relatives) and Windows Server.
The agent is written in Rust, uses a few dozen MB of memory at rest and negligible CPU, and runs without permanent root privileges.
Yes. Up to 5 servers monsys.ai is free, with no time limit and no credit card. From the sixth server you pay €3 per server per month.
Datadog is broader but US-based and per-metric priced. Zabbix is free but requires self-hosting and upkeep. monsys.ai sits in between: SaaS convenience, EU hosting and a flat price. See the comparison pages for details.
Installation takes a few minutes. No credit card, no obligations.
Architecture, Trust Score formula, supply-chain pipeline, NIS2 / AI Act / CRA mapping. Free PDF after a short form.
