Salt Security vs. Akto
Akto guards the endpoint. Attacks happen in the enterprise APIs behind it.
Akto pivoted from API testing to AI agent security in 2025, building a platform around endpoint hooks, MCP proxies, and per-server guardrail activation. That architecture secures what flows through the endpoints you configure. Salt Security secures the downstream enterprise APIs, business logic, and data infrastructure that agents interact with after those endpoints — where attacks actually cause damage at scale.

Salt Security: purpose-built agentic security
The full fabric — from endpoint to downstream enterprise API
Salt Security secures the layer below and beyond Akto's endpoint model: the enterprise APIs, business logic, and downstream services where agents execute real-world actions. The Agentic Security Graph maps and correlates LLM connections, MCP servers, APIs, identities, and sensitive data as a unified fabric — no per-server activation, no hooks to deploy, no endpoints to register.
- Agentic Security Graph across LLM, MCP, and API layers
- Downstream enterprise API and business logic protection
- Unified governance — no per-server activation required
- Identity-aware multi-step sequence correlation across the full fabric
- East-west and internal API coverage without endpoint hooks
- Runtime-to-code remediation loop
- Eight years of production API security research behind every detection
Akto: Endpoint Hooks, MCP Proxies, and Red Teaming
Per-server guardrails at the tool and endpoint level
Akto started as an API testing tool and pivoted to AI agent security in 2025. Its architecture deploys endpoint hooks into MCP clients, proxies between clients and servers, and runs automated red teaming simulations. Guardrails are activated per MCP server via YAML configuration rules, giving teams control at the tool invocation level — but no visibility into downstream enterprise APIs.
- AI agent and MCP server discovery
- Automated red teaming with 1,000+ attack probes
- Endpoint-level guardrails for prompt, tool, and output violations
- Per-server guardrail activation required for each MCP server
- No coverage of downstream enterprise APIs and business logic
- Hook and proxy model scoped to configured endpoints, not the full fabric
- No Agentic Security Graph — no cross-fabric identity and sequence correlation
Head-to-head
The agentic capabilities
endpoint hooks and proxies can’t reach
Akto controls what happens at the tool invocation level. Salt monitors what happens to your enterprise APIs when those tools execute. These are the capabilities that require fabric-wide visibility, not per-server configuration.
| Feature | Description |  |  |
|---|---|---|---|
| Unified Agentic Discovery | Discovers APIs, MCP servers, and AI-driven assets across external exposure, cloud, code repositories, and runtime. |  |  |
| Agentic Security Graph | Correlates LLMs, MCP servers, APIs, identities, and sensitive data in one action-layer context. | | |
| Salt Code Governance | Governs API and MCP creation in repositories, pull requests, and developer workflows before risky logic reaches production. | | |
| Runtime-to-Code Remediation | Feeds runtime findings back into DevOps workflows and AI coding assistants to fix root causes. | | |
| Agent-Aware Sequence Correlation | Tracks unique agentic identities and multi-step intent across sessions, tools, and services. | | |
| Behavioral Action-Layer Protection | Detects machine-speed business-logic abuse beyond signatures, schemas, or prompt filters. | | |
| Internal & East-West Coverage | Protects internal APIs and downstream service interactions that edge-only and model-only tools miss. | | |
| Action-Layer Data Security | Maps sensitive data in motion across APIs, MCP servers, and agent actions. | | |
| Beyond Endpoint Hooks and MCP Proxies | Secures downstream enterprise APIs and business logic, not just local hook, shield, or proxy activity. | | |
| Business-Logic Protection for Downstream APIs | Detects abuse in the enterprise APIs behind the agent, not just prompt, tool, or endpoint policy violations. | | |
| No Per-Server Guardrail Activation Required | Applies governance as a unified platform capability rather than requiring selection of individual MCP or agent servers for policy activation. | | |
Why it matters
Endpoint guardrails stop the prompts.
Fabric-level coverage stops the attacks.
Akto catches violations at the tool. The damage happens downstream.
Akto's endpoint hooks and MCP proxies are well-suited for catching malicious prompts, tool poisoning, and policy violations at the point of tool invocation. What they cannot see is what happens after a permitted tool call executes — the downstream API requests, business logic interactions, and data flows that constitute the actual attack surface at enterprise scale.
Salt's Agentic Security Graph correlates the full chain: from LLM request through MCP tool invocation through API execution through downstream service interaction. Attacks that look clean at the endpoint level become visible as behavioral anomalies when the full sequence is correlated. That requires eight years of API security research applied to a fabric-wide model — not endpoint hooks on individually configured servers.
What Salt catches that Akto misses
- Business logic abuse in downstream enterprise APIs — each tool call individually authorized, the sequence malicious
- East-west internal API interactions triggered by agent actions after initial tool execution
- Shadow APIs and rogue MCP servers created outside any hook or proxy configuration
- Multi-step attack sequences spanning MCP servers that have not been individually activated for guardrail coverage
- Risky API and MCP logic in repositories before any endpoint has hooks deployed against it
Salt code
Security before any endpoint has a hook configured
Akto's guardrail model requires MCP servers to be individually selected and activated for policy coverage. Salt Code governs API and MCP creation at the repository level — scanning pull requests for risky integrations before they ship, with no per-server configuration required. Runtime findings feed back into developer workflows automatically, closing the loop between what gets detected in production and what gets fixed at the source.
