Your AI writes the code.
Hiro secures it.

Reactive security is a bug. Your tools scan, alert, and hand you a list of problems. Hiro finds flaws and fixes them.

CODE SECURITY

Every PR gets a security review. Finally.

Hiro is embedded in your AI coding agents. It reviews plans before code is written and catches issues as they’re generated — not after. Zero setup, zero extra work for engineers.

Inline Plan Review

Before your AI agent writes a single line, Hiro reviews the plan. Insecure auth patterns, dangerous API designs, and misconfigured infrastructure get caught at the intent stage — before they become code.

Real-Time Code Review

As your agent generates code, Hiro evaluates it for vulnerabilities, hardcoded secrets, insecure dependencies, and misconfigurations. Issues never make it into the PR.

Embedded, Not Bolted On

No CI pipeline to configure. No dashboard to check. Hiro lives inside Claude Code, Cursor, and Copilot — engineers get secure code without changing their workflow.

Agent Plan
1. Create auth module with JWT signing
2. Store secret in config object
3. Add login endpoint to Express router
Hhiro · plan review
Step 2: Storing secret in config object will hardcode it. Use process.env instead.
Step 3: Login endpoint needs rate limiting. Adding express-rate-limit middleware.
Revised Plan
1. Create auth module with JWT signing
2. Read secret from process.env.JWT_SECRET
3. Add login endpoint with rate limiter (100 req/min)

SECURITY HARDENING

Find your weak spots. Lock them down.

Hiro continuously scans your cloud environments, SaaS tools, and security products for misconfigurations and exposed resources — and hardens them.

Misconfiguration Detection

Scans AWS, GCP, Google Workspace, GitHub, Supabase, Vercel, and more against security benchmarks. Catches the settings that get missed — overly-permissive IAM roles, wide-open sharing defaults, disabled MFA, misconfigured EDR policies.

One-Click Resolution

Hiro generates the fix — the IAM policy update, the security group change, the encryption toggle — and you apply it with one click. No context-switching into cloud consoles to figure out what to change.

Agent Integration

Add Hiro as an MCP server to your coding agent. When your agent provisions infrastructure or modifies cloud resources, Hiro validates the changes in real time — the same way it reviews code.

Cross-Tool Context

Hiro understands the relationship between your code, your infra, and your identity layer. A code change that opens a new API endpoint triggers a check on the corresponding cloud resources.

ALERT TRIAGE

Your GuardDuty alerts are noise. Hiro handles them.

Enable Hiro on your alert sources. It analyzes every alert, filters the noise, and notifies you only when something actually needs attention — with plain-English next steps any engineer can act on.

One Toggle, Full Coverage

Connect GuardDuty, CloudTrail, Datadog, or any alert source. Hiro starts analyzing immediately — no rules to write, no thresholds to tune.

Signal From Noise

Most security alerts are false positives. Hiro correlates context across your stack to determine what’s real and what’s not — so your team isn’t triaging hundreds of alerts they don’t understand.

Actionable Next Steps

When something is real, Hiro tells you what happened, why it matters, and exactly what to do — in language an engineer can act on, not security jargon.

Compliance as a Byproduct

Every alert analyzed and every incident surfaced gets logged as compliance evidence automatically. SOC 2 readiness builds in the background.

SECURITY POSTURE

Your tools don’t talk to each other. Hiro does.

Hiro connects to your entire stack and builds a security context that no single-tool scanner can match.

Integration Hub

Connect your stack in minutes — GitHub, GitLab, AWS, GCP, Azure, Okta, Datadog, PagerDuty, Jira, Slack, and more. One config, no agents.

Organizational Memory

Hiro builds a persistent understanding of your security context — past incidents, business-critical services, team ownership, compliance requirements — so every finding is prioritized with full context.

Ask Hiro

Ask questions about your security posture in plain English. “Are we affected by this CVE?” “What’s our biggest risk right now?” “Are we SOC 2 ready?” Hiro answers with real context from your stack — not a dashboard you have to learn to read.

Teams using Hiro ship faster and sleep better.
