Octiga vs Reach Security - MS E3/E5 Optimization: Side-by-Side Comparison (2026)

MSPs managing Microsoft 365 for multiple customers need Octiga because it applies security baselines across tenants from a single dashboard, eliminating the manual baseline work that scales poorly across clients. The tool handles auto-remediation of M365 misconfigurations 24/7 and covers the full tenant stack, Exchange Online through Intune, which means fewer security gaps slip past your annual audits. Skip this if your customers are mostly on-premises Exchange or if you need detection and response capabilities beyond M365; Octiga is posture management, not threat hunting. Mid-market and enterprise teams drowning in Microsoft security feature sprawl should use Reach Security - MS E3/E5 Optimization to stop paying for unused E5 capabilities and fix the E3 configs that actually matter. It maps your current setup against real attack telemetry, then tells you which security controls you're leaving on the table, which ones are misconfigured, and whether the E5 upgrade is worth the spend for your threat profile. Skip this if you've already got deep Microsoft security expertise in-house or you're not willing to act on upgrade recommendations; the value sits entirely in closing the gap between what you own and what you're actually running.
