Frequently Asked Questions
Bylaw vs Sublime Security: which should you choose?
Choose Bylaw if you build AI agents that perform sensitive business actions and need to prevent decisions based on stale or conflicting evidence. Choose Sublime Security if your priority is defending against advanced email threats like BEC and VEC with custom detection rules. They solve entirely different problems, so your use case dictates the choice.
Can Bylaw be used for email security?
No, Bylaw is designed for AI agent runtime enforcement, not email security. For email threats, use Sublime Security.
Does Sublime Security detect AI agent errors?
No, Sublime focuses on email threats like phishing and BEC, not on AI agent action correctness.
Which tool has a free tier?
Neither. Both require contacting sales for pricing, indicating enterprise-level commitment.
Can I use both tools together?
Yes, they solve non-overlapping problems. You could use Bylaw to guard your agents and Sublime to protect your email.
Which integrates with LangChain?
Bylaw integrates with LangSmith, Langfuse, OpenAI, Braintrust, and MCP—ecosystems often used with LangChain, but not directly stated.
Does Sublime offer behavioral analysis?
Yes, it analyzes sender and recipient patterns to detect anomalies, a core part of its AI detection.
Is Bylaw suitable for simple rule-based agents?
It's overkill. Bylaw is for agents making sensitive calls based on external evidence; simple rule-based agents likely don't need it.
Do either support custom detection rules?
Sublime offers Sublime Script (YARA-like) for custom rules. Bylaw uses a deterministic policy engine but no script language.
