A single missed log entry can invalidate a PCI DSS audit.
What PCI DSS expects from infrastructure access
PCI DSS requires that every person who interacts with cardholder data be uniquely identified, that all privileged actions be logged, and that sensitive fields be protected from accidental exposure. The standard also mandates just‑in‑time approval for high‑risk commands, and it expects the audit trail to be immutable, searchable, and retained for at least one year. In practice, this means an organization must be able to answer three questions for any incident:
- Who initiated the connection?
- What commands were executed or queries run?
- Did any response contain cardholder data that should have been masked?
PCI DSS does not prescribe a particular tool; it only demands that the evidence be complete, accurate, and tied to a verifiable identity.
Why traditional access patterns fall short
Most teams rely on static credentials or long‑lived service accounts to reach databases, SSH hosts, or Kubernetes clusters. Those credentials are often shared across engineers, automated jobs, and third‑party scripts. The result is a blurry audit trail: the system logs a generic "service account" entry, but it cannot tell which individual triggered a particular query. Inline data masking is rarely applied, so responses that contain PANs or CVVs flow unfiltered to the client. Approvals for risky commands are handled manually, usually via email or a ticket, leaving no automated record of the decision.
Even when an organization adopts OIDC or SAML for authentication, the identity check stops at the gateway. The request then proceeds directly to the target resource without any further inspection. At that point the connection is invisible to the compliance team: there is no session recording, no real‑time masking, and no automated justification for why a privileged command was allowed.
How hoop.dev delivers the required evidence for PCI DSS
hoop.dev is a Layer 7 gateway that sits between identities and the infrastructure they need to manage. It is the only place where enforcement can happen, turning the abstract PCI DSS requirements into concrete, verifiable controls.
Session recording for every connection
When a user or an automated agent connects through hoop.dev, the gateway records the full protocol exchange. The recording lives outside the target host, so the host cannot delete or tamper with it. Auditors can replay any session to see exactly what was typed, what queries were sent, and what responses were returned. This satisfies the PCI DSS demand for a complete, immutable audit trail.
Inline data masking on responses
hoop.dev can mask sensitive fields such as credit‑card numbers, expiration dates, or security codes in real time. The masking occurs before the data reaches the client, ensuring that only authorized personnel ever see the clear values. Because the masking policy is enforced at the gateway, the underlying database never needs to be re‑engineered for compliance.
Just‑in‑time approvals for high‑risk actions
For commands that could expose or modify cardholder data, hoop.dev can pause the request and route it to a designated approver. The approver’s decision is logged alongside the session, providing proof that the operation was authorized. This aligns with PCI DSS’s requirement for documented, on‑demand approvals for privileged actions.
Identity‑aware policy enforcement
Authentication is handled via OIDC or SAML, and hoop.dev reads group membership to apply fine‑grained policies. The setup step decides who may request access, but the gateway is the only component that actually enforces the policy. Without hoop.dev in the data path, the identity check alone would not prevent a privileged command from running.
Putting it together for Devin
Devin’s environment typically contains databases that store payment information, internal APIs that surface transaction details, and SSH hosts used for maintenance. By routing all of those connections through hoop.dev, Devin gains a single control surface that fulfills the three PCI DSS evidence pillars: unique identity, complete session logs, and protected data flows. The gateway’s open‑source nature means the team can self‑host it, keep the audit data on‑premise, and tailor masking rules to the specific fields that appear in Devin’s schemas.

FAQ
Does hoop.dev replace existing firewalls or network ACLs?
No. hoop.dev operates at the application protocol level, complementing network controls. It adds visibility and enforcement where firewalls cannot see individual commands or data fields.
Can I use hoop.dev with existing CI/CD pipelines?
Yes. The gateway presents the same client interfaces (psql, kubectl, ssh, etc.), so pipelines can invoke those tools through hoop.dev without code changes. All actions are still recorded and masked.
How long are the session recordings retained?
Retention is a policy decision made by the organization. hoop.dev stores recordings in a location you control, allowing you to meet PCI DSS’s one‑year retention requirement.
