Our verdict: Microsoft Security Copilot
Security Copilot is essential if your organization is full Microsoft (M365 E5, Sentinel, Defender): return on investment is immediate, especially with E5 inclusion. If you don't use the Microsoft ecosystem, the appeal is marginal. For SMBs on M365 Business Premium, the E5 barrier remains high:but monitor 2026/2027 pricing changes that could democratize access.
Our verdict: SentinelOne Purple AI
Purple AI is one of the most advanced SOC AI solutions on the market in 2026, notably thanks to its free agentic investigation trial for all customers. If you already use SentinelOne Singularity, test it immediately: ROI is measurable. For an SMB without an internal SOC, SentinelOne globally remains a mid-market/enterprise solution; seek an MDR partner to operate it for you.
