寻找Cisco MARS的替代者
去年底，Cisco宣布要终结MARS产品，并且订立了最后销售的时间点2011年6月3日。如今，时间已经过去半月多，各位购买了MARS产品的用户们，估计正在考虑找寻MARS的替代产品吧。也就剩下一年了，之后Cisco就不维护MARS的软硬件了。
SIEM产品原本就很复杂，从采购到实施到运维都要付出很多，因此，选择SIEM产品应该很慎重，而做SIEM的厂商也要很慎重，要有长期交付的能力。从用户方来说，在选择SIEM类产品的时候应该倾向于选购具有长期交付能力的厂商，具有持续服务能力的厂商。
Cisco算是大厂了，幸好他在退出SIEM市场的同时给出了一份详细的系统迁移建议，提出了多种方案供用户选择。但你会那么幸运吗？
