1Security Microsoft Copilot Security is a commercial data security posture management tool by 1Security. MerlinCryption ASBE is a commercial data security posture management tool by MerlinCryption. Compare features, ratings, integrations, and community reviews side by side to find the best data security posture management fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams deploying Microsoft Copilot across M365 need visibility into what data the AI can actually access before oversharing becomes a compliance liability, and 1Security Microsoft Copilot Security is built explicitly for that pre- and post-deployment control. The tool maps Copilot's permissions through Microsoft Graph, flags excessive access across SharePoint and OneDrive, and automates remediation of misconfigurations, addressing the asset management and data security gaps that most M365 tenants haven't solved yet. Skip this if your organization hasn't standardized on Microsoft's ecosystem or if you're looking for a Copilot governance tool that also covers other generative AI platforms; 1Security is Microsoft-only.
Enterprise and mid-market teams protecting highly sensitive data against quantum-capable adversaries should evaluate MerlinCryption ASBE for its nondeterministic encryption approach, which generates unique ciphertext on every operation and eliminates the mathematical relationships that make traditional algorithms vulnerable to both quantum and AI-driven attacks. The patented random data generator and variable key sizes up to 2GB provide measurable resistance to statistical analysis where conventional block ciphers fail. The on-premises deployment and lack of key transfer or storage reduce your attack surface significantly, though the four-person vendor team and India-based operations mean you're betting on a micro-vendor without the support infrastructure of established players like Thales or Fortanix.
