Lynis vs Sysdig Secure

Lynis performs security health scans to support system hardening and compliance testing on Linux, macOS, and Unix-based systems. Its stated uses also include security auditing, penetration testing, and vulnerability detection, for audiences such as developers, system administrators, IT auditors, and penetration testers. The tool checks components and tools found on each system through modular, opportunistic scans and is described as having almost no dependencies. It includes 300+ built-in tests and allows custom tests. Results appear on screen; technical details go to a log file, while warnings and suggestions are kept in a separate report. Lynis can help test security practices associated with CIS benchmarks, NIST, NSA, OpenSCAP data, and vendor guides. Listed systems include AIX, FreeBSD, HP-UX, Linux, macOS, NetBSD, NixOS, OpenBSD, and Solaris, along with Raspberry Pi, IoT, and QNAP devices. The free GPLv3 version costs nothing and comes without warranties or support. Lynis Enterprise SaaS is listed at $36 a year per system, billed annually; self-hosted Enterprise pricing is by quote.
