We are looking at requiring smb signing on our network. The fact that Microsoft and others say to expect a 15% performance impact makes that a hard pill to swallow. My question, would the types of attacks and lateral movement exploited by not requiring smb signing be blocked by Sophos Endpoint / Intercept X? We just want to avoid taking a performance hit to protect ourselves against something we might already be protected from. I've tried searching around on this one but can't find any indication either way.
