Enhanced threat detection through superior sandboxing capabilities with competitive pricing
With Trend Micro Deep Discovery, our enterprise clients can identify forgotten or unmanaged network segments, thereby mitigating unexpected network actions such as outdated antivirus software operations. When under attack, such as with ransomware, it allows us to identify the attack vector and disable it. It also assists in security audits required to prove certain network security measures.
