Check Point Harmony Email has achieved Gartner Magic Quadrant Leader recognition with an API-first deployment approach that requires no MX record changes and good BEC and impersonation detection capabilities. The prevention-first philosophy that defines Check Point's broader security portfolio applies to email as well.
The independent benchmark validation depth is less extensive than Proofpoint or Microsoft. Review volume on Gartner and G2 is lower than the market leaders, which limits buyer confidence in the ratings. The value is strongest for existing Check Point customers wanting to extend their existing vendor relationship to email.
The verdict: Check Point Harmony Email is right for existing Check Point customers wanting to consolidate email security into their existing vendor relationship with a capable API-first product. Organisations evaluating email security independently should shortlist Proofpoint, Mimecast, or Abnormal Security.
