The only survival strategy we have seen is to find a way to keep the lawyer (and sometimes the communications director) out of the meetings. If that is possible, the CISO’s key job is to encourage senior executives to understand how little chance there is that the company will be able to keep a lid on the information and how much worse late disclosure is than early disclosure.”

By blocking malicious behaviors independent of what the threat or exploit is, ASR can protect enterprises from never-before-seen zero-day attacks like these recently discovered vulnerabilities: CVE-2017-8759, CVE-2017-11292, and CVE-2017-11826.”
