Just as security has evolved from just the perimeter to now include strategies for insider threats, convergence is the next phase of evolution in enterprise-level security incident prevention, detection and management. The most extensible, scalable and robust solution for addressing this convergence is enterprise security management (ESM). The same capabilities ESM utilizes for correlation, anomaly detection, pattern discovery, reporting, investigation and remediation within the IT security realm can also be applied to and converged with, physical security solutions. Organizations are learning that operational efficiencies are amplified by convergence, yielding a positive impact on return on investment (ROI).

Additionally, they are finding that their overall security posture is improved by reducing risk and leading to a more solid return on security investment (ROSI). The global security climate has changed with terrorists, organized crime groups, nation-state threats and so forth. Organizations must continue to adapt to these trends with solutions and countermeasures that are capable of merging these disciplines. Enterprise security management (ESM) solutions can be the core for such convergence, thus allowing organizations to mitigate the risks in a holistic and efficient manner. Before the advent of ESM, convergence was brute force at best. Today, the technology is up to the challenge, and many organizations have already achieved success.
