In today's digital landscape, cybersecurity threats are becoming increasingly sophisticated and prevalent. To combat these evolving threats, organizations are turning to Security Operations Centers (SOCs) to proactively monitor, detect, and respond to security incidents in real-time.
While commercial SOC solutions offer comprehensive features, they often come with hefty price tags, making them inaccessible for some organizations, particularly smaller businesses or those with limited budgets. Luckily, the open-source community offers a plethora of robust and feature-rich SOC tools that can empower organizations of all sizes to establish an effective security posture without breaking the bank.
This blog post dives into some of the best open-source SOC tools available, highlighting their strengths and how they can be integrated into your security infrastructure.
