Networks are becoming less centralized and more complex — as are the threats they face from bad actors. The attack surface rapidly expands as workplaces move more resources and remote devices outside the protection of corporate networks. Meanwhile, longstanding risks like ransomware and distributed denial of service (DDoS) attacks are growing increasingly sophisticated. IT leaders need a defense in depth strategy to protect their networks — a layered approach with multiple security solutions to address a wide range of potential threats. Organizations are also looking to centralize their security services for more comprehensive control of their protection.
