  • NAC Solutions Evolve to EVAS: Endpoint Visibility, Access, and Security

    Network access control has been around for a decade, and the global recession and years of vendor consolidation certainly took a toll on NAC solutions. But NAC is not fading away. Instead, NAC has evolved into a new and stronger market segment called EVAS (Endpoint Visibility, Access, and Security).  CISOs should place NAC in their legacy file and begin to assess EVAS as part of their security strategies.

    EnCase Analytics: Big Data Security Analytics Meets Endpoint Visibility

    Over the last few years, security professionals continue to fall farther and farther behind with security controls and incident detection.  Why?  Many organizations approach cybersecurity with an array of signature-based tools, perimeter gateways, disjointed processes, and limited security resources/skills. These legacy tactics can no longer keep up with increasingly dangerous threats.  CISOs can improve situational awareness with the right big data security analytics to help with controls adjustments, incident detection, problem isolation, and remediation.  EnCase Analytics, with all the requirements of a big data security analytics solution, will provide built-in algorithms, ad-hoc query capabilities, and security technology integration in order to help organizations accelerate, automate, and streamline overall cybersecurity operations. Additionally, by focusing on the often neglected area of endpoint artifacts, EnCase Analytics can help security-conscious organizations benefit from proactive assessment of the security risks and gain complete visibility into their security posture.

    IBM: An Early Leader across the Big Data Security Analytics Continuum

    Many enterprise organizations claim that they already consider security data collection and analysis as “big data,” but they don’t have security analytics solutions capable of addressing their scalability, performance, or operational needs. ESG believes that tactical security analytics solutions and compliance-centric SIEM tools are no match for today’s big data security analytics needs. Leading vendors are addressing this gap with real-time and asymmetric big data security analytics systems built for scale and intelligence. IBM is one of few vendors offering an integrated approach that spans the entire continuum of enterprise security analytics needs.

    Imbalance Between Server and Network Security Controls

    The balance of security processes and skills is lopsided in most organizations. Network security trumps server security at most organizations in a number of ways, from IT experience to the common perception that networks simply require more expansive security efforts than servers. ESG investigated the state of network and server security at midmarket and enterprise organizations, and considered the ramifications for organizations that expend more security resources on their networks at the expense of their servers.
