Why Now Is the Right Time to Migrate to Splunk - And How to Do It Right

As legacy SIEM platforms, such as IBM QRadar, reach the end of their support lifecycle, many organizations are reevaluating their security and observability strategies. Businesses across industries face rising cybersecurity threats, increasing regulatory pressure, and the need for more data-driven operations. 

Splunk helps organizations become more digitally resilient, meaning they are better prepared, quicker to respond, and able to adapt to threats before they escalate.

According to the Splunk State of Security Report, even 41% of high-value security alerts go unnoticed due to limited SOC capacity. So, why should you consider migrating now, and how can your organization make this transition without significant downtime?

Why Migration Matters Now?

1. Cybersecurity is business-critical - Security is no longer just an IT concern. Attacks like ransomware, DDoS, or privilege escalation cause real business damage: financial loss, reputational risk, and data breaches. Comprehensive platforms like Splunk can detect vulnerabilities faster, better prioritise incidents and comply with evolving regulations like GDPR or NIS2.
2. Legacy systems are a liability - Legacy platforms can’t keep up with hybrid and cloud-native environments. They are often slow, expensive to maintain, and vulnerable to evolving threats. Migrating to a modern observability platform not only helps to future-proof your infrastructure but also takes workload away from your security team.
   
   
3. Data as a strategic asset - The ability to use data to optimize performance, improve service delivery, and identify new market opportunities will remain a key source of competitive advantage in all industries. New technologies will generate new waves of data to manage - and extract value from - even as they allow us to offer new products, services and experiences. Splunk helps organizations turn raw data into insights, whether it’s understanding customer behavior, tracking service health, or enabling predictive operations.

4. The AI advantage - AI is the cornerstone of big data processing. For over 10 years, Splunk has been bringing AI into the everyday work of security and operations teams, and continues to innovate to help SOCs accomplish their mission of protecting organizations. With native AI and machine learning capabilities, Splunk accelerates threat detection, takes manual work with automation, and supports smarter decision-making across your IT and security operations.
