Zero Trust for GitHub Enterprise

Close the token loophole: continuous identity, device, and context verification for every GitHub request — across UI, CLI, SSH, and API.

Identity

  • Verified Developer
  • SSO-bound, trusted user

Platform

  • GitHub Enterprise
  • Repos, PRs, Actions

Device

  • Secure Endpoint
  • Patches, EDR, encryption

Policy

  • EDAMAME Trust
  • Continuous access decisions
  • Blocks token-based attacks
  • Virtual air gap around your repos
  • Developer-friendly rollout

Built for CTOs & CISOs securing GitHub Enterprise Cloud.

The Risk

Your repositories are one token away from a breach.

GitHub tokens and SSH keys operate outside the login flow. A stolen token looks completely legitimate to GitHub — no MFA check, no device verification. Compromised laptops and rogue CI runners can grant attackers full access to private repos without touching your SSO or VPN.

  • Stolen PATs and SSH keys bypass identity and device checks.
  • Malware on a developer laptop turns it into an attacker workstation.
  • Git / SSH / API access happens outside your login flow.
  • Traditional device trust covers login, not the GitHub operations that matter.

SECURITY GAP

The Token Loophole

Identity and device-trust tools validate posture at login. GitHub grants access long after, using tokens and keys that never go back through those checks.

Once a token leaks, attackers can clone, push, and exfiltrate code from any device. With no continuous verification, the identity & device trust you paid for no longer applies.

The Solution

Zero Trust, enforced at the GitHub layer.

  • Identity: SSO-bound, verified developer accounts.
  • Device: OS patches, encryption, EDR, firewall, and integrity checks.
  • Context: IP, environment, CI runner state, and access patterns.

EDAMAME continuously verifies every GitHub interaction — not just login. For every request, we evaluate identity, device posture, and context before GitHub grants access.

Only when all signals pass does GitHub allow the operation. Everything else is blocked — tokens alone are no longer enough.

ARCHITECTURE

EDAMAME orchestrates GitHub’s own security controls — Conditional Access and dynamic allowlists — so that GitHub itself only serves requests from verified users on secure devices.

Developer Device → EDAMAME Trust Engine → GitHub Enterprise

No inline proxies. No custom tunnels. Just native enforcement at the point where it matters: your code platform.

Core Capabilities

Everything you need to secure GitHub without slowing developers.

EDAMAME brings Zero Trust principles to your entire SDLC — from laptops to CI runners — while keeping workflows fast and familiar.

  • Verified developer identity: Bind every device to a corporate identity via SSO/IdP. Tokens, SSH keys, and CLI access are always tied back to a real, verified person.
  • Continuous device posture: Enforce encryption, patches, EDR, firewall, and integrity. If a device drifts out of compliance, its GitHub access is revoked in real-time.
  • Native GitHub enforcement: Use GitHub Enterprise's Conditional Access and IP allowlists as the enforcement point. EDAMAME keeps them up-to-date for you.
  • CI/CD & mobile coverage: Apply the same trust model to CI runners, build agents, and mobile devices that interact with GitHub.
  • Developer-friendly experience: Lightweight agents and clear remediation guidance. Engineers keep their tools and workflows — security runs in the background.
  • Works with your stack: Integrates with your IdP, VPN, EDR, MDM/UEM, secrets managers, and CI tooling. No rip-and-replace.

Comparison

EDAMAME delivers the security guarantees of on-prem and air-gapped systems — with the speed and flexibility of modern cloud development.

More than VPNs, air gaps, or IP allowlists.

  • Alternative: VPN / Tailscale / ZTNA
    Once a device connects, it's often fully trusted. Posture checks are sparse, and GitHub access is not evaluated per request.

  • With EDAMAME
    Every GitHub request is gated by current identity and device posture. No tunnels. No implicit trust.

  • Alternative: On-prem / air-gapped Git
    Strong isolation, but difficult for distributed teams, SaaS integrations, and cloud-native CI/CD.

  • With EDAMAME
    Create a virtual air gap around GitHub Cloud. Only verified devices and identities can reach your repos.

  • Alternative: Static IP allowlists
    Hard to maintain. Developer IPs change. No visibility into which device is behind an IP.

  • With EDAMAME
    Dynamic, per-device allowlisting. GitHub only accepts traffic from currently trusted endpoints.

Migration

From on-prem to GitHub Cloud — without losing control.

Move from self-hosted or air-gapped Git to GitHub Enterprise Cloud with a Zero Trust model that keeps — and improves — your security posture.

  1. Assess & plan: Discover repos, users, devices, and CI pipelines. Map risks and target state for GitHub Cloud.
  2. Bind identity & devices: Connect to your IdP and enroll developer devices. Establish posture baselines.
  3. Enforce GitHub trust: Turn on dynamic allowlisting and Conditional Access enforcement for GitHub Enterprise.
  4. Secure CI/CD: Validate CI runners and build agents before they pull code or secrets.
  5. Complete migration: Decommission legacy Git while maintaining consistent Zero Trust enforcement across all repos.

Threat Scenarios

Real attacks, blocked by design.

Scenario: Stolen personal access token

  • Without EDAMAME: Attacker uses the token from any device to clone private repos.
  • With EDAMAME: Device not verified or out of posture → GitHub rejects all requests using that token.

Scenario: Compromised developer laptop

  • Without EDAMAME: Malware pushes or exfiltrates code using existing GitHub credentials.
  • With EDAMAME: Posture deteriorates → device automatically removed from allowlist → GitHub access revoked.

Scenario: Rogue CI/CD runner

  • Without EDAMAME: Malicious runner pulls secrets and injects backdoors into builds.
  • With EDAMAME: Runner fails posture or integrity checks → denied before accessing repos or secrets.

Trust & Impact

Security leaders choose EDAMAME to harden their SDLC.

Combine the assurance of air-gapped systems with the agility of GitHub Cloud. EDAMAME lets you enforce Zero Trust without sacrificing developer velocity.

Stop supply-chain attacks at the source — your repos.

Strengthen compliance for SOC 2, ISO 27001, NIS2, DORA, and more.

Win developer trust by making security feel invisible.

EDAMAME gave us the confidence to move to GitHub Enterprise Cloud with the security guarantees we used to get from air-gapped infrastructure — without slowing our teams down.
