Fail2Ban vs Inspektor Gadget: at a glance
What is Fail2Ban?
Fail2Ban finally ships 1.1.1 after 14 months in beta, with a botched deb package on the way out the door
Fail2Ban watches log files for authentication failures and bans the offending addresses through the local firewall. It remains a default component of Linux server hardening, and its release cadence has never matched that prominence — six releases in the eight years before this one. The 1.1.1 final has now landed, closing a beta that had sat unfinished since June 2025, and it installs a systemd-managed socket rather than relying solely on the daemon's own startup.
What is Inspektor Gadget?
Inspektor Gadget v0.58 adds SELinux and rename tracing and fixes stale OTel series
Inspektor Gadget v0.58.0 adds trace_selinux for SELinux AVC decisions and trace_rename for file renames, an opt-in OpenTelemetry snapshot mode that drops series for processes that no longer exist, and IPv6 support in trace_sni. The profiler fork was rebased onto upstream, and trace_fsslower's output format changed in a breaking way. v0.57.0 had already let gadgets run rootless with narrow capabilities.

◆ Current state
Fail2Ban watches log files for authentication failures and bans the offending addresses through the local firewall. It remains a default component of Linux server hardening, and its release cadence has never matched that prominence — six releases in the eight years before this one. The 1.1.1 final has now landed, closing a beta that had sat unfinished since June 2025, and it installs a systemd-managed socket rather than relying solely on the daemon's own startup.
◆ Where it's heading
The pattern is long silences broken by releases that mostly absorb external change — Python 3.12 and 3.13 compatibility in 1.1.0, a Dovecot filter regression in 1.0.2 — with the substance deferred to a ChangeLog the feed does not carry. What is different this time is the contributor list, which runs to a dozen first-time contributors, suggesting the delay was throughput rather than abandonment. The release also had to be re-cut: the first Debian package shipped with wrong paths from a missing systemd-dev build dependency and was pulled and replaced.
◆ Prediction
Given the beta-to-final gap just closed and the volume of first-time contributors merged into it, the useful thing to watch is whether the next release arrives in months rather than years; the entries do not indicate what it would contain.

Inspektor Gadget v0.58 adds SELinux and rename tracing and fixes stale OTel series
◆ Current state
Inspektor Gadget v0.58.0 adds trace_selinux for SELinux AVC decisions and trace_rename for file renames, an opt-in OpenTelemetry snapshot mode that drops series for processes that no longer exist, and IPv6 support in trace_sni. The profiler fork was rebased onto upstream, and trace_fsslower's output format changed in a breaking way. v0.57.0 had already let gadgets run rootless with narrow capabilities.
◆ Where it's heading
The project is pairing two tracks: reducing the privileges and trust an eBPF tool needs (rootless runs, multi-tenancy, hardened parsing) and making its output fit standard observability pipelines (OTel metrics and profiles). New gadgets keep widening security-relevant coverage.
◆ Prediction
Expect further OpenTelemetry alignment and more security-focused gadgets; the experimental multi-tenancy from v0.56 has not yet shown a path to stable in the entries.
