CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and SMB security teams drowning in alert noise will benefit most from Ostra Security's managed SIEM paired with its 24/7 SOC; you're paying for humans to actually investigate and tune tools rather than licensing another detection platform you'll ignore. The vendor scores particularly strong across NIST Detect and Respond functions, covering continuous monitoring through incident mitigation, which means you get both the alerting and the response coordination in one service. This is not the right fit if you need deep platform security hardening or proactive vulnerability management; Ostra prioritizes what happens after compromise, not prevention.
Mid-market organizations where Microsoft 365 is the crown jewel and phishing is the loudest alarm should pick Attic MDR for its real-time detection of fake login pages paired with forced verification screens that actually stop credential theft at the gate. The vendor covers NIS2 compliance reporting and daily automated remediation against CIS standards, meaning your team stops manually patching configuration drift. Skip this if you need visibility beyond Microsoft's ecosystem or rely on on-premises Active Directory; Attic's strength is depth in cloud identity and email, not breadth.
