Cybersecurity Evolution Brings Shifts for Network Security (TechTarget)


Jon Oltsik, an analyst with Enterprise Strategy Group Inc. in Milford, Mass., said he sees a broader cybersecurity evolution driving changes affecting enterprise network security. Network security is shifting toward a software-defined, cloud-based model, with microsegmentation systems from Illumio, vArmour and Edgewise and software-defined perimeters from Cryptzone, Google and other vendors.

Oltsik said he views next-generation firewalls as a legacy technology, and he anticipates changes in endpoint security from signature-based antivirus to enhanced endpoint security systems as another key factor in cybersecurity evolution. Suppliers such as Carbon Black, Cybereason and CrowdStrike have begun offering threat detection with  endpoint protection software tools, while Cylance bases its threat prevention system on artificial intelligence.

Oltsik said he also sees cybersecurity evolution for networking driven by increased bundling of security information and event management systems from AlienVault or IBM with other security analytics products. He indicated that user behavioral analytics products from Hewlett Packard Enterprise, Securonix and Exabeam are also seeing increased adoption, alongside threat intelligence platforms from Demisto, Phantom and Resilient.
