Network Access Control (NAC) Evolves Into Endpoint Visibility, Access, and Security (EVAS) Market Says ESG

ForeScout well positioned to capitalize on EVAS market growth driven by BYOD/mobility and transition to continuous monitoring and mitigation

The network access control (NAC) market is evolving rapidly into a broader, more mainstream information security category called Endpoint Visibility, Access and Security (EVAS), according to a new report from Enterprise Research Group (ESG). As a superset of NAC, EVAS technology will provide greater endpoint visibility and automated control. EVAS means to serve as the core of a more integrated and coordinated security infrastructure and aligns with ForeScout’s platform strategy and market growth.

“As NAC has transformed into EVAS, the need for next generation, market leading NAC solutions such as ForeScout CounterACT has become stronger than ever,” said Jon Oltsik, senior principal analyst at ESG. “Given the advantage of continuous monitoring and mitigation, smart CIOs and CISOs are seeking EVAS capabilities to optimize IT resources and to gain more efficient responses to prevent or contain security exposures. In this regard, Forescout has demonstrably advanced its platform to meet these market requirements.”

In the report, “The Endpoint Visibility, Access, and Security (EVAS) Market: The Evolution of Network Access Control (NAC),” ESG projects that as NAC transforms into EVAS it will become even more of a mainstream IT technology driven by:

  • Increases in network device population driven by end-user mobility and BYOD: ESG expects the number of companies banning BYOD devices and requiring the use of company-issued devices will decline from 62 percent today to 22 percent within five years
  • Transition to continuous monitoring and mitigation: Many organizations today lack visibility and control over endpoints and applications connected to the network and are migrating to tools for continuous monitoring and mitigation
  • Need for further security operations automation: Budget pressure and availability of skilled IT professionals as well as the dynamic and phased nature of network threats create pressing needs for the greater automation delivered by EVAS technology
  • Drive toward  “contextual security:” EVAS helps enable more effective use of other security technologies by providing real-time knowledge about who, what, where, why and when a user or device is on the network
