5. Strategic Recommendations

• Align with Business Needs: Select a SIEM tool that matches organizational size, compliance needs, and threat profile.
• Consider Total Cost of Ownership: Factor in deployment, training, and operational costs beyond the license price.
• Prioritize Vendor Support: Opt for a provider with reliable support to ensure smooth operation.
• Invest in Scalability: Choose solutions that can adapt to future growth and increased data volumes.

6. Conclusion

SIEM tools play a pivotal role in modern cybersecurity frameworks. While Splunk( officially part of Cisco and positioned under Cisco's broader portfolio ) leads in analytics, Microsoft Sentinel offers cost-effective cloud solutions, and IBM QRadar stands out with advanced threat detection. Organizations should conduct detailed pilot testing to validate compatibility with their specific environments.
