Do we need a separate e-signature tool?

No. Signatures are handled in Probo. Each one is sealed with a SHA-256 hash and an RFC 3161 timestamp, and the signer receives a Certificate of Completion by email.

Who can we ask to approve a document?

Anyone in your user list. Pick approvers when you publish, or save default approvers on the document so every major version goes to the same people.

What happens if one approver rejects?

The version goes back to draft. Every approver has to approve before the major version is published, and you can void a pending request at any time.

What is the difference between a minor and a major version?

Approval and signatures. A minor version publishes immediately, skips approval, and keeps the signatures already collected. A major version can require approval, and you request signatures again for it.

Will people get one email per document?

No. Probo waits 15 minutes, then groups every pending approval or signature for a person into a single email with one link.

Do people get reminded if they forget to sign?

Yes. Probo sends up to three reminders, spaced one, two, and three days apart, and moves any reminder that falls on a weekend to Monday.

Can we request signatures from the whole team at once?

Yes. Select several documents and several people, and Probo creates every request in one step. Each person signs once per major version.

Can we automate this with an AI agent or n8n?

Yes. The Probo MCP server exposes 24 document tools, the n8n node has 22 Document operations, and webhooks fire on every publish, approval, and signature event.

What can we show our auditor?

Everything. Download any version as a PDF with its signatures and approval details, add a watermark with the classification, your own text, and a timestamp, link documents to controls, and use the audit log to trace every change to a controlled record.

Can we add diagrams and tables to our documents?

Yes. The editor supports headings, tables, code blocks, and Mermaid diagrams, and you can paste Markdown straight in. Diagrams render in the PDF export too.

Can we export all our documents?

Yes, in one step. Your compliance data is yours. Select every document, and Probo emails you a ZIP of PDFs with the same signature and watermark options. Probo is open source and can be self-hosted, so nothing keeps you locked in.

Can we publish policies on our Compliance Portal?

Yes. Set each document's visibility on your Compliance Portal separately, so internal drafts never leave your workspace.

Who keeps the documents up to date?

Your team does, with Probo keeping the record. Edit in a draft, publish when ready, and every earlier version stays in history with its approvals and signatures. Unless you want Probo to manage your compliance, in which case we write your documentation and you approve it.

Information Security Policy in Probo with approvals and signatures

Every policy, from first draft to signed record, in one place.

Write drafts, publish minor or major versions, and collect approvals and signatures that stay attached to the exact version your team reviewed.

Controlled documents, versioned

Keep policies, procedures, plans, and registers as versioned records, each with a changelog and a classification.

Approvals from the people you choose

Pick approvers from your user list, and publish the new version only once every one of them approves.

Minor or major, your call

Publish a small fix as a minor version, or a major version that goes back through approval.

Electronic signatures built in

Collect signatures inside Probo, with no separate e-signature tool and a sealed certificate for every signer.

Emails and follow-ups handled

Let Probo email each approver and signer, then follow up with reminders so you do not have to.

Keep control of every version without chasing anyone

Choose approvers, choose minor or major, and request signatures, while Probo emails each person and follows up on your behalf.

Send drafts to the right approvers

Choose approvers from your user list, or save default approvers per document.
Email every approver one link to approve or reject, with an optional comment.
Publish the major version only when every approver agrees, and return it to draft on a rejection.

Publish minor or major versions

Publish typo fixes and small edits as a minor version, with no approval round.
Publish a major version directly, or route it through an approval quorum first.
Record a changelog with every publish, so each version explains what changed.

Collect electronic signatures inside Probo

Request signatures from one person, or from your whole team across several documents at once.
Let people review and sign from their employee portal, without another tool or account.
Send each signer a Certificate of Completion with a SHA-256 seal and a trusted timestamp.
