Pros

None - Mimecast leadership seems intent of stripping away all pros it once had

Cons

Treats AI like a people-replacement, not a tool Chaotic yearly layoffs Whole scale company direction changes every 6 months ELT revolving door, likely leading to the above points Constantly buying new technology - no longer an innovator or leader in the cybersecurity space
