    Webhook Signature Verification for CPaaS: HMAC, Replay Windows, and Tenant-Owned Rotation on Devotel Orbit

    The security half of a webhook integration: the three replayable failure modes (no signature, weak secret, no timestamp check), the verification recipe as pseudocode plus a worked curl against a live Orbit delivery, the tenant-owned levers (secret rotation, IP-allowlisting posture, per-endpoint retry backoff, the retry log), and the edge-vs-consumer decision.

    SOC 2 vs ISO 27001 — the CPaaS buyer's guide to assurance frameworks

    Which assurance framework a CPaaS RFP is really asking for, what SOC 2 Type II and ISO 27001 certificates each prove, the tenant-owned controls that answer either one, and the checklist of questions to run against every vendor on your short list.

    PCI-DSS on messaging channels — the CPaaS buyer's checklist for scope separation

    A runnable checklist for evaluating a CPaaS vendor on PCI-DSS scope when payment flows touch SMS, email, RCS, or WhatsApp — which channel surfaces carry cardholder data, how Devotel Orbit's Stripe-based SAQ A posture applies per channel, and when to bring in a QSA.

    The enterprise CPaaS due-diligence checklist: SCIM, audit logs, and tenant controls

    Enterprise buyers short-list CPaaS vendors on identity plumbing, not channel counts. This checklist maps the questions procurement and security teams ask — SCIM lifecycle, SSO pairing, API-key network controls, audit evidence, tenant isolation — to the exact Devotel Orbit surface that answers each one.

    Scoped agent credentials, pinned regression replay, and the Agent ROI guide

    A worked guide to three Devotel Orbit agent capabilities: OAuth 2.0 Token Exchange for scoped, auditable agent credentials, regression tests pinned to a prompt version with candidate-version pre-promotion scoring, and setting up the Agent ROI attribution numbers.
