Spinboss Protect  /  Security & Compliance
§ SC — Security & Compliance Posture

Security and compliance posture, audited to the layer of the message.

Spinboss Protect treats each enforcement communication as a discrete artefact that must be authentic at origination, intact in transit, and reviewable in retention. The posture below is published as a public reference for counterparties and recipients.

§ SC.01

SPF Authentication

Spinboss Protect publishes an authoritative SPF record enumerating each authorized relay and applies a strict -all fail-closed policy. Receiving systems that observe a message claiming this domain from an unauthorized origin will reject the connection at SMTP time.

§ SC.02

DKIM Signing

Outbound messages are signed using RSA-2048 keys against rotating public selectors. Key rotation follows a published schedule with overlap windows to avoid signature breakage during transit.

§ SC.03

DMARC Policies

DMARC is published at p=reject with adkim=s and aspf=s, ensuring receivers enforce strict alignment. Aggregate (rua) and failure (ruf) reports are ingested and reviewed.

§ SC.04

TLS Encryption

All transport hops enforce TLS 1.3 with AEAD ciphersuites. MTA-STS policy is published at mode=enforce, and TLS-RPT surfaces transport failures for review.

§ SC.05

Secure Mail Relay

A dedicated authenticated relay tier handles all enforcement communications, isolated from any general-purpose corporate mail systems. Each relay is independently attested with a published fingerprint.

§ SC.06

Infrastructure Logging

All ingress, signing, dispatch, and acknowledgement events are written to append-only logs with content-hash chaining, retained under documented retention windows.

§ SC.07

Compliance Monitoring

Continuous monitoring tracks authentication posture, retention compliance, retention window expirations, and counterparty acknowledgement SLA adherence.

§ SC.08

GDPR Alignment

Personal data referenced in correspondence is minimized to what is strictly necessary, retained under documented retention windows, and subject to data-subject rights under the GDPR and equivalent regional frameworks.

§ SC.09

Data Retention Policies

Correspondence and operational logs are retained for the durations published in our Compliance Statement, after which they are securely destroyed or anonymized under written procedure.

§ SC.10

Abuse Prevention Framework

An abuse prevention framework governs the dispatch of enforcement notices, including duplicate detection, claim verification, and proportionality review prior to outbound action.

§ SC.11

Incident Escalation Standards

Incidents affecting infrastructure integrity, key custody, or counterparty acknowledgement are escalated under a documented severity matrix with paired-approval response.

§ SC.12

Operational Integrity Controls

Separation of duties, paired approval for material change, immutable change logs, and external review on a documented cadence enforce operational integrity.

§ SC.13 — Topology

Infrastructure topology

The simplified topology to the right shows the five logical layers any outbound enforcement message traverses: ingress gateway, authentication (SPF/DKIM/DMARC), TLS relay, verification core, and audit logging. Every layer is independently attested.

Each layer publishes a fingerprint on the Infrastructure Status page, allowing counterparties to confirm that the layer was operational and unaltered at the moment a referenced message was dispatched.
