## Arcjet

Arcjet started life as a developer-friendly security layer for web applications and has expanded into runtime security for AI agents. Instead of only checking identity at the door, it evaluates every step an agent takes: which tool is being called, with which typed arguments, by which actor, and in the context of the steps that came before. That lets teams stop unauthorized refunds, unexpected data access, runaway token spend and sequence drift that no single step would have flagged on its own.

The platform combines classic application protections - WAF, bot detection, rate limiting, signup form protection and email validation - with agent-specific controls such as prompt injection detection, tool and MCP authorization, sensitive information detection and data loss prevention. Detection for sensitive data can run locally in your environment so regulated payloads never leave your infrastructure, while decisions and policy versions stream out to SIEM tools like Splunk, Datadog, Panther and Cribl for evidence.

Arcjet ships SDKs for JavaScript and Python ecosystems (Next.js, Astro, Express, Fastify, NestJS, Nuxt, SvelteKit, Hono, Flask, FastAPI, Bun, Deno and more) plus integrations for agent frameworks including LangChain, LangGraph, CrewAI, Google ADK, Mastra, OpenAI Agents, Vercel AI SDK and the Claude Agent SDK. It also offers an MCP server, a CLI and skills for coding agents such as Claude Code, Codex and Cursor. A free trial is available, with paid plans and custom/enterprise pricing on request.

**Pricing & Plans:** Free trial available, then paid plans with custom pricing for larger deployments. Enterprise and volume pricing is quoted on request. Check the official pricing page for current tiers and usage limits.

- **Agent action policy enforcement:** Wrap agent tool calls and get a typed decision - allow, block, redact or hold for review - before the tool actually executes, based on actor, role, route and typed inputs.
- **Prompt injection detection:** Screen user input, fetched web pages, API responses and tool output for hostile instructions before anything reaches the model context.
- **Sensitive information and DLP:** Detect and strip names, addresses, national IDs, bank and card numbers before they reach model context, logs or third-party tools, with optional in-process local detection.
- **Web app protections:** Bot protection, WAF rules, rate limiting, signup form protection and email validation to keep public endpoints and signup flows clean.
- **Audit and observability:** Every decision, policy version and actor is retained as evidence and streamed to Splunk, Datadog, Panther, Cribl or your own analytics warehouse, with OpenTelemetry agent traces.

**Strengths:** Evaluates the whole agent run, not just a single request, which catches sequence drift and multi-step abuse; Detection can run in-process so sensitive data does not have to leave your environment; Broad SDK and agent-framework coverage, including an MCP server, CLI and coding-agent skills; Decisions and policy versions stream to common SIEM and observability stacks for compliance evidence

**Limitations:** Requires code changes inside your application rather than a purely network-level gateway deployment; The breadth of controls and frameworks means a real learning curve for smaller teams; Advanced enterprise governance and custom retention options are quote-based rather than self-serve

## Merge

Merge is an infrastructure company that builds the 'context layer' for AI agents and products. Its flagship product, Merge Unified, gives developers a single API to read and write customer data across hundreds of third-party systems — HRIS, payroll, ATS, CRM, accounting, ticketing, and file storage — replacing dozens of bespoke integrations with normalized data models, Merge Link, webhooks, and field mappings.

On the agentic side, Merge Agent Handler connects AI agents to thousands of pre-built, authenticated tools so they can take real actions across third-party services, while Merge Gateway routes every LLM call through one API with failover, spend limits, and performance controls. Merge for Workforce extends this internally: IT can push approved models, MCP connectors, and skills to employee AI tools, set budgets per team, and apply DLP scanning and audit logging.

Merge is built for teams that need enterprise compliance out of the box; it is certified SOC 2 Type II, ISO 27001, HIPAA, and GDPR-compliant, and supports SAML SSO, RBAC, field-level scopes, selective sync, and integration observability. Pricing is freemium at the entry and contract-based at scale, making it accessible for startups shipping a proof of concept and for enterprises needing white-glove support.

**Pricing & Plans:** Freemium with contract-based tiers. The Launch plan includes 3 production Linked Accounts free, then $650/month for up to 10 Linked Accounts with $65 per additional account and volume discounts. Professional and Enterprise plans are contract-based with custom fields, field-level scopes, custom sync frequencies, enterprise security, SLAs, and premium support.

- **Unified API for data integrations:** One normalized API connects your product to hundreds of HRIS, payroll, ATS, CRM, accounting, ticketing, and file storage systems with read and write access.
- **Agent Handler tool access:** Give agents secure, authenticated access to thousands of pre-built tools across third-party services, with scoped permissions and audit logs.
- **LLM Gateway and routing:** Route every model through one API with automatic failover, pre-built or custom routing rules, and spend and performance controls.
- **Merge for Workforce governance:** Distribute approved MCP connectors, models, and skills to employee AI tools with per-team budgets, DLP scanning, and audit logging.
- **Enterprise security and observability:** SOC 2 Type II, ISO 27001, HIPAA, and GDPR compliance plus SSO, RBAC, logs, health monitoring, and linked account management.

**Strengths:** Replaces dozens of bespoke integrations with a single maintained API; Covers both data integrations and agentic tool access in one platform; Strong enterprise compliance posture with SOC 2 Type II, ISO 27001, HIPAA, and GDPR; Governance features like DLP, per-team budgets, and audit logs suit large organizations

**Limitations:** Pricing scales quickly once you exceed the free linked accounts; Contract-based tiers require a sales conversation to get exact quotes; The breadth of products can be complex to navigate for small teams
