Security and event management and log management products are continuing to gain greater awareness as the threat and vulnerability landscape increase. As these types of attacks become more sophisticated, organizations are implementing security products, such as a SIEM, to protect virtual and physical assets. Aside from core features, netflow analysis, data loss prevention, and vulnerability scanning have been key features offered as an add-on to a SIEM or part of a whole security suite. The market has also seen the move from software appliances to physical appliances and now virtual appliances. The increase of sales and use of managed services has also served as an option for organizations looking to implement a SIEM in their operations.
