Infonaligy Proofpoint Email Security vs Sophos Email: Side-by-Side Comparison (2026)

Infonaligy Proofpoint Email Security

SMB and mid-market teams without dedicated email security staff should choose Infonaligy Proofpoint Email Security for its managed service model, which offloads detection and response to Infonaligy's team rather than requiring internal tuning. The platform covers the full email attack surface,phishing, BEC, compromised accounts, malicious URLs,with particular strength in behavioral and ML-based detection that catches account takeovers most signature-only tools miss. Enterprise buyers with large security operations centers and the budget to run Proofpoint independently will find this managed wrapper unnecessary; you're paying for convenience and training integration, not additional detection power you couldn't get by staffing it yourself.

Sophos Email

Mid-market and enterprise teams already running Sophos endpoint or MDR will extract real value from Sophos Email because the threat intelligence flows both directions, catching BEC and supply-chain phishing that isolated email gateways miss. The 20+ ML models and native integration with Sophos X-Ops means suspicious emails trigger endpoint investigations automatically without manual handoffs. Skip this if your organization needs email security completely decoupled from your endpoint vendor, or if you're heavily invested in a non-Sophos EDR and want to avoid vendor consolidation.
