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.
