    Tsunami

    Tsunami

    Network security scanner for detecting severity vulnerabilities

    Tsunami is a general purpose network security scanner with an extensible plugin system for detecting high severity vulnerabilities with high confidence. When security vulnerabilities or misconfigurations are actively exploited by attackers, organizations need to react quickly in order to protect potentially vulnerable assets. As attackers increasingly invest in automation, the time window to react to a newly released, high severity vulnerability is usually measured in hours. This poses a significant challenge for large organizations with thousands or even millions of internet-connected systems. In such hyperscale environments, security vulnerabilities must be detected and ideally remediated in a fully automated fashion. To do so, information security teams need to have the ability to implement and roll out detectors for novel security issues at scale in a very short amount of time. Furthermore, it is important that the detection quality is consistently very high.
