Signal is built on a non-custodial model. Your CRM and mailbox stay your systems of record. OAuth tokens are encrypted with AES-256 GCM. Access is limited to the minimum required to run the workflow.
Non-custodial by design. Your data stays in the systems you already control.
Signal does not replicate, warehouse, or retain your CRM records, mailbox data, or contact graph. Your existing tools remain the single source of truth.
Non-custodial is not a security setting. It is a design decision that shapes what Signal stores, what it accesses, and how it operates within your stack.
When the boundaries between your data and a vendor's reach are unambiguous, security review becomes faster and trust is easier to build.
Signal operates as a workflow layer — not a second CRM or a shadow mailbox.
Signal connects to your tools to discover, qualify, and sync journalist records. It does not become a second CRM or a shadow mailbox.
Your CRM owns the contact graph. Your mailbox owns the message history. Signal runs a defined job and hands the result back to your systems.
Every permission Signal requests is tied to a specific workflow step — discovery, sync, or outreach — not broad platform access.
Authorized connections with encrypted token storage — not vague security promises.
Signal uses OAuth to connect to your CRM and mailbox. OAuth lets you grant specific, revocable permissions without sharing your passwords.
OAuth tokens are credentials. How they are stored and protected determines the real security of the connection — not just whether OAuth was used.
Signal encrypts all stored OAuth tokens with AES-256 GCM — authenticated encryption that provides both confidentiality and integrity protection.
Specific, auditable encryption — not marketing language.
Saying 'enterprise-grade encryption' tells a buyer nothing. Naming the cipher (AES-256), the mode (GCM), and the use case (OAuth token storage) gives reviewers something they can actually evaluate.
OAuth tokens grant authorized access to third-party systems. Weak token storage can expose the very accounts OAuth was designed to protect.
When buyers or security teams can see the specific encryption model, they can compare it against their own standards and make faster procurement decisions.
Narrow scope. Less exposure. Cleaner trust.
Signal requests only the permissions required to execute the workflow — reading contacts for sync, sending messages for outreach, and nothing beyond that.
Every additional permission is a potential surface area. Limiting scope to the minimum means less risk if a token is ever compromised.
When buyers see a narrow permission list, the trust conversation shifts from 'what could go wrong' to 'this is well-scoped.'
Four steps that define how Signal connects, protects, scopes, and defers to your systems of record.
You authorize Signal to connect to your CRM and mailbox through standard OAuth flows. No passwords are shared or stored.
All OAuth tokens are encrypted with AES-256 GCM before storage — authenticated encryption that protects both confidentiality and integrity.
Permissions are scoped to the minimum required for each workflow step. No broad platform access, no unnecessary data reads.
Your CRM and mailbox remain your systems of record. Signal operates as a workflow layer — it does not replicate or warehouse your data.
Security should be legible. Signal names the cipher, the mode, and the scope of access. When a vendor makes its security model easy to read, review goes faster and trust is cleaner.
Constrained access over hidden accumulation. Signal does not quietly expand its reach into your systems. It asks for the minimum it needs, encrypts what it stores, and keeps your tools as the systems of record.
