Security Considerations

A tool is only as effective as its implementation. Consider these factors:

  • Configuration matters: Default settings may not match your threat model. Review security options carefully.
  • Training is essential: Tools protect nothing if your team doesn't use them correctly or consistently.
  • Integration points: Consider how this tool connects with your existing systems and what data flows between them.
  • Continuity planning: Ensure you have backup access methods and know the recovery process.
