Bylaw
Runtime enforcement platform that blocks AI agents from acting on wrong evidence before execution.
Bylaw fills a critical gap in agent reliability by focusing on evidence integrity rather than just tool permissions. It's a must-consider for any team deploying autonomous agents that can take irreversible business actions. If you need to prevent actions based on wrong evidence and require signed audit trails, Bylaw stands out against generic guardrails like Lakera or Rebuff, which focus on injection and permissions. However, it requires engineering effort and custom pricing.

Skip Bylaw if you lack agent-driven automations or sensitive tool calls that rely on external evidence, or if you're not prepared to invest engineering effort to integrate the SDK and define policies.
Custom pricing means you must contact sales, and costs could scale with usage or number of protected actions.
Bylaw uses contact-sales pricing, which fits enterprise teams with budget for custom security solutions. For smaller teams, consider generic guardrails like Lakera or Rebuff, which may offer self-serve tiers.

About Bylaw
Bylaw is a runtime enforcement platform that prevents AI agents from executing actions based on incorrect, stale, conflicting, or unauthorized evidence. It goes beyond simple tool-call permission checks by verifying the factual basis behind each sensitive action—such as CRM updates, customer messages, refunds, or workflow triggers—before it reaches your production systems. Bylaw is designed for engineering and product teams building AI agents, especially those integrating with CRMs, support systems, billing platforms, or internal tools. It provides two complementary modes: Trace-to-Gate, which analyzes past agent runs to identify evidence failures, and a runtime SDK that enforces evidence gates in real time. You wrap sensitive actions with the Bylaw SDK. Before the action executes, Bylaw checks an evidence manifest against deterministic policy rules—looking for missing, stale, conflicting, or unauthorized data. It can block, allow, or route risky actions to human review, and it maintains signed audit records. What makes Bylaw different is its focus on evidence, not just tool permissions. While most guardrails check whether an agent can call a tool, Bylaw checks whether the agent can rely on the facts it used. This addresses a growing failure mode in agent deployments where correct tool calls are made with bad evidence.
Behind the Verdict
Bylaw addresses a specific and painful problem: AI agents that make confident but wrong decisions because they act on stale, conflicting, or unauthorized evidence. Most guardrails check permissions—can this agent call this tool?—but Bylaw checks evidence—is the data behind this action trustworthy? That's a meaningful distinction. The platform offers two complementary modes: Trace-to-Gate, which replays historical agent runs from logs (LangSmith, Langfuse, OpenAI, Braintrust, MCP) to identify where evidence failures occurred, and a runtime SDK that enforces deterministic evidence gates before sensitive actions execute. This lets you find problems in your past and prevent them in the future. The deterministic policy engine is a standout: it compiles your SOPs and rules into structured rule packs, with versioned approval before production deployment, so the runtime decisions are reproducible and audit-friendly. Signed audit records for every decision are a strong plus for compliance teams. The human-in-the-loop routing for risky actions is pragmatic—it doesn't try to automate everything, it escalates when uncertainty is high. Where does Bylaw fit? It's for engineering teams building agents that touch CRMs, billing, or customer communications—places where a wrong action has real consequences. It's not for simple rule-based agents that don't depend on external evidence. The biggest hurdle is the engineering effort: you need to integrate the SDK and define evidence policies, which takes time and expertise. There's no public pricing, so you'll need to talk to sales, which may be a barrier for smaller teams. Also, the deterministic approach means you need to be able to formalize your evidence rules, which isn't always straightforward. Compared to generic guardrails, Bylaw is more specialized and more powerful for its niche. It's not a wrapper on a foundation model—it's a purpose-built enforcement layer. If you're deploying autonomous agents that can take irreversible actions, Bylaw is worth a serious look.

Real-world workflow fit
Concrete scenarios for the personas Bylaw actually fits — and what changes day-one when you adopt it.
The team is building an AI agent that updates CRM records automatically, but they're worried about bad data from chat logs overwriting the system of record.
Outcome: They integrate the Bylaw SDK on CRM write actions, define an evidence policy requiring the agent to reference the system of record, and deploy. Now, if the agent tries to update based on stale chat data, the action is blocked and routed to human review.
The company must audit every decision made by AI agents that process refunds, to meet internal and regulatory standards.
Outcome: They use Bylaw's signed audit records to log each evidence check, providing a tamper-evident trail for every refund decision. They also run Trace-to-Gate on historical logs to identify past failures and fix policies.
They're planning to deploy autonomous agents that can take irreversible actions like modifying billing or sending customer messages.
Outcome: They use Bylaw to enforce evidence gates on all sensitive actions, with human-in-the-loop routing for risky ones. They simulate allow/review/block decisions on historical runs to tune policies before go-live.
Use Cases
- Prevent CRM updates based on conflicting customer information from chat vs. system of record
- Block refund requests that lack order and shipping evidence
- Halt customer messages that cite outdated policy documents
- Reject pricing tests launched from weak or conflicting revenue data
- Trigger human review for actions using unauthorized long-term memory notes
- Audit every agent decision with signed evidence manifests
Limitations
- No pricing information is publicly available; you must contact sales.
- The tool requires engineering effort to integrate the SDK and define evidence policies.
- It may not suit simple agents that don't rely on external data sources.

Where the pricing makes sense
The company stage and team size where Bylaw's pricing actually pencils out — and where peers do it cheaper.
Bylaw uses contact-sales pricing, which fits enterprise teams with budget for custom security solutions. For smaller teams, consider generic guardrails like Lakera or Rebuff, which may offer self-serve tiers.
Setup time & first value
How long it actually takes to get something useful out of Bylaw — broken out by persona, not the marketing-page minute.
Integrating the SDK and defining initial policies typically takes a few days to a week for an engineering team familiar with the codebase. Running Trace-to-Gate on historical logs can be done quickly, but iterating on policies takes time.

Featured Head-to-Head Comparisons
Bylaw vs Sublime Security
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.
Bylaw vs Audioeye
Bylaw and AudioEye serve entirely different needs. Bylaw is a niche runtime guardrail for AI agent evidence verification, ideal for engineering teams building agents that interact with CRMs and billing systems. AudioEye is a broad accessibility compliance platform for websites, targeting legal risk reduction for ADA/WCAG. Choose based on your primary threat: wrong AI actions vs. accessibility lawsuits.
Bylaw vs Push Security
Choose Push Security if your team needs to secure browser-based attacks (AiTM, ClickFix, session hijacking) and control AI tool usage in real time. Choose Bylaw if you are building AI agents that take sensitive business actions (CRM updates, refunds) and need runtime evidence validation. Push is broader for security teams; Bylaw is specialized for agent builders.
