ArcSight
ArcSight aggregates, normalizes, and enriches event data across your organization for greater threat visibility.

Splunk
We make machine data accessible, usable and valuable to everyone—no matter where it comes from. You see servers and devices, apps and logs, traffic and clouds. We see data—everywhere. Splunk offers the leading platform for Operational Intelligence. It enables the curious to look closely at what others ignore—machine data—and find what others never see: insights that can help make your company more productive, profitable, competitive and secure.

ArcSight and Splunk are both terribly clever at what they do, which is to sit in a corner, hoover up vast amounts of logs and then make very serious faces while telling you where the digital monsters are lurking. They excel at real-time threat detection, integrate with all sorts of arcane security tools and even dabble in machine learning, which is a bit like teaching a cat to detect intruders by staring at probability charts. Both can live in the cloud or in a big, humming server room where they mutter darkly about anomalies.

ArcSight, born in 2000 in the USA (which was a particularly good year for security paranoia), was originally designed for those who enjoy wearing suits and discussing cyber threats in hushed tones. It boasts a formidable correlation engine that is so good at spotting patterns, it could probably predict the next season’s fashion trends if asked. It does, however, require a team of dedicated professionals to make it behave and setting it up is about as straightforward as assembling flat-pack furniture with missing instructions.

Splunk, on the other hand, arrived in 2003 with a cheeky grin and a much more relaxed approach. Originally intended for log analysis and IT operations, it quickly realized that security was where the action (and the budgets) were. It’s friendlier, easier to scale and has a knack for making data look nice with colorful dashboards that almost make security seem fun. Unlike ArcSight, it’s equally at home with DevOps, IT monitoring and anything else that involves trawling through mountains of machine data for something interesting—or alarming.
