\frametitle{What is MISP?}
\begin{itemize}
       \item MISP is a {\bf threat information sharing} platform that is free \& open source software
       \item A tool that {\bf collects} information from partners, your analysts, your tools, feeds
       \item Normalises, {\bf correlates}, {\bf enriches} the data
       \item Allows teams and communities to {\bf collaborate}
       \item {\bf Feeds} automated protective tools and analyst tools with the output
       \item MISP is a complete threat intelligence platform with strong sharing capabilities and extendability
\end{itemize}

  \frametitle{Cryptographic signing and tamper protection}
  \begin{itemize}
     \item Need to be able to share and ensure the {\bf veracity of critical events}
