  • If community support and documentation are not available, then don’t go for such a free tool. Prefer having proper documentation and support communities to avoid any untoward situation in case of any issue.

• Customizability
  • Can you tweak the settings of the tool to fit your operations? Whether it’s scheduling scans or adjusting alerts, flexibility is crucial when protecting dynamic business environments.
