Frequently Asked Questions
Exogram vs Sublime Security: which should you choose?
If you deploy AI agents in production and need deterministic governance with cryptographic audit, Exogram’s open-core model and ultra-low overhead (0.07ms/decision) make it a standout choice for security-conscious teams. For advanced email threat detection (BEC, VEC) with low false positives, Sublime Security offers powerful custom detection via Sublime Script—but its contact-only pricing and reliance on M365/Google Workspace limit flexibility. Choose Exogram for agent security; choose Sublime for email security.
Which tool has lower false positives?
Sublime Security emphasizes low false positive rates through adaptive learning. Exogram is deterministic—it doesn't rely on LLMs for decisions, so false positives are a matter of policy configuration, not AI uncertainty.
Can Exogram detect phishing emails?
No—Exogram is a governance layer for AI agent actions, not an email security platform. For email threats, Sublime Security is the appropriate choice.
Does Sublime Security integrate with AI agent frameworks?
No. Sublime integrates only with Microsoft 365 and Google Workspace for email protection. Exogram integrates with LangChain, AutoGen, CrewAI, and more.
Which tool is better for compliance?
Exogram is purpose-built for compliance (SOC 2, EU AI Act) with cryptographic audit trails. Sublime Security helps with email security compliance but lacks agent-specific audit.
Is Exogram open source?
Exogram is open-core—the core governance engine is open source, with enterprise features (SSO, RBAC, SIEM) as paid add-ons.
What is Sublime Script?
Sublime Script is a YARA-like language in Sublime Security for writing custom email detection rules, enabling fine-tuned threat hunting.
Can Exogram work with any LLM agent?
Yes—it provides a REST API and MCP integration, plus SDK wrappers for popular frameworks, making it agent- and LLM-agnostic.
Does Sublime Security offer a free tier?
No, Sublime Security is paid with contact-only pricing. Exogram offers a free community edition.
