Talion can help you leveraging your ArcSight investment and remove the risks & costs associated with transitioning to a new SIEM provider.

How we can help
Extend and Enhance your Arcsight Investment​

SIEM effectiveness isn’t about what platform you are on, it is how you are using it. By limiting yourself to out of the box or a small number of in-house content, the ability of your SIEM to catch nefarious activities is greatly reduced.

Optimise the value of your alerts and reduce analyst fatigue

More relevant content means more relevant alerts. This also means that analysts are doing decent investigations worthy of their time rather than being wasted on false positives.

Remove the risk & cost associated with transitioning to a new SIEM provider​

We understand that the threat to your business is constantly changing and evolving, that’s why our content team work to understand threats relevant to your business, only then can we develop content to truly protect you.
