Security Agent hybrid scan

Application Security

Pre-deployment scan with Security Agent

Agent catches issues as it writes your code. In addition, Security Agent does a comprehensive scan of your app with hybrid static + LLM-based scanning, reducing false positives by 90%.

Data protection with separated databases and secret management

Data Security

Secure defaults to protect data

Development and production databases are fully separated. Passwords and API keys are never exposed to your code or the AI — and full version history means nothing is ever lost.

Enterprise-grade infrastructure with isolated GCP, DDoS protection, and WAF

Infrastructure Security

Enterprise-grade security for all

Every customer gets their own isolated Google Cloud project — even on free tier. Each deployment ships with DDoS protection and a WAF, the same infra Fortune 500s rely on.

Auto-Protect vulnerability monitoring

Continuous monitoring

24x7 monitoring with Auto-Protect

After you ship, Replit Auto-Protect monitors your published apps around the clock against newly disclosed CVEs, automatically prepares a patch, and sends you a direct link to apply it.

Built for enterprise teams

The controls, compliance, and visibility that enterprise IT and security teams require — all built in.

Explore Enterprise

SSO

SAML and OIDC with Okta, Azure AD, Google, and any compliant identity provider.

SCIM

Automated provisioning and deprovisioning synced from your identity provider.

Role-Based Access Control

Granular permissions for viewing, editing, and deploying across your org.

Private Deployments

Keep internal prototypes private. Control who can access what you build.

Audit Logging

Full visibility into who did what and when across your organization.

Security Center

Act on vulnerabilities in bulk across all apps in your organization.

Secured on all fronts

Independent layers of security work together to reduce risk at every level.

Inside our security approach

Isolated sandboxes, backend separation, built-in auth, supply chain protection, and pre-deploy scanning — working from day one.

Isolated Sandboxes

Hardened Linux containers with seccomp-bpf, migrating to microVMs for the strongest isolation available.

Backend Separation

A real backend, not just Row Level Security — true architectural separation between your app's layers.

Dev / Prod Separation

Forkable databases via snapshots ensure dev and production never interfere with each other.

Built-In Auth

Turnkey Clerk-based authentication ships out of the box — no need to build login yourself.

Supply Chain Protection

Determinate Nix keeps packages patched and pinned to exact versions. Nothing slips in silently.

Shift-Left Security

Real-time code evaluation catches security issues as the AI writes your code during development.

Security Agent

SAST and SCA analysis powered by Semgrep, HoundDog, and LLM reasoning scans every app before publish.

Auto-Protect

Monitors published apps 24/7 for new CVEs and automatically prepares a patch you can apply instantly.

No cross-app access, transparent secret handling, and irrecoverable-proof backups.

Scoped Data Access

No cross-app access unless explicitly opted in. Each app's data is invisible to every other app.

Secret Proxying

Credentials injected via a sidecar proxy at runtime — never stored in code, never visible to the AI Agent.

Continuous Backups

Daily backups and an append-only git history that can't be rewritten — so nothing is ever permanently lost.

Zero trust architecture, per-customer cloud projects, and DDoS protection on every deployment.

Zero Trust

Mutual TLS, short-lived tokens, least-privilege access, and network segmentation platform-wide.

Per-Customer GCP

Every customer gets their own Google Cloud project — even on free tier. A real infrastructure boundary.

Cloud Armor + WAF

DDoS protection and a web application firewall on every deployment, automatically.

Bug bounties, penetration testing, AI red-teaming, and a hardening cycle for every incident.

Bug Bounty

Security researchers worldwide continuously test the platform through a public HackerOne bounty reward program.

Penetration Testing

Commissioned in-depth security reviews by Trail of Bits stress-test every layer of platform infrastructure.

AI Red-Teaming

An internal security harness continuously probes and tests the AI Agent for safety and security boundaries.

Incident Hardening

Every root cause from every incident feeds back into the platform as a permanent, automated hardening measure.

For founders

Shipping your first app?
You're already covered.

Every app you build on Replit gets enterprise-grade security from day one — the same protections our enterprise customers get.

Pre-publish comprehensive security scanning with Security Agent

Separation between development and production databases means changes in development does not affect your app in production

24X7 watch over your apps for vulnerabilities in your dependencies with Replit Auto-Protect

Automatic backups mean you can always roll back

Compliant and certified

Frequently asked questions

Your data is hosted on Google Cloud Platform. Every Replit customer gets their own isolated GCP project — even on free tier. This means your data is separated at the infrastructure level, not just logically.

Every project runs in its own hardened Linux container with seccomp-bpf policies, and we're migrating to microVMs for even stronger isolation. This is real infrastructure-level separation, not just logical rules on a shared database.

Credentials are injected via a transparent sidecar proxy at runtime. They're never stored in your code, never visible in the editor, and never accessible to the AI Agent. Even if your code were exposed, your secrets wouldn't be.

Yes. Every app goes through automated security scanning before it can be published. This includes SAST and SCA analysis powered by Semgrep, sensitive data detection via HoundDog, and an additional LLM reasoning layer that catches context-dependent issues traditional scanners miss.

Yes. Replit holds SOC 2 Type II certification. We also comply with GDPR and are working toward ISO 27001 certification.

We follow a root-cause-to-hardening cycle: every incident is fully investigated, the root cause is identified, and a corresponding hardening measure is built into the platform. We work with named security partners including Trail of Bits and HackerOne to continuously test and improve.

Most vibe coding platforms rely on Row Level Security on a shared database and offer minimal infrastructure isolation. Replit provides real backend separation, per-customer GCP projects, 14 distinct security layers, pre-publish scanning, and enterprise controls like SSO, SCIM, and RBAC. The architecture is fundamentally different.

Ship fearlessly
