Probo’s trust center is a dedicated security and compliance page for your organization that you can share with customers, prospects, and partners. It surfaces your framework certifications, published policies, and security updates in one place — reducing the time your team spends responding to individual security questionnaires.

​
Visibility settings

Your trust center has three visibility modes:
ModeWho can view
NONETrust center is disabled and not publicly accessible
PRIVATEAccessible only to visitors who have been granted explicit access
PUBLICAccessible to anyone with the link
You can change the visibility mode at any time. Switching from PUBLIC to PRIVATE immediately requires visitors to authenticate or present an access grant.

​
Setting up your trust center

1

Choose a slug

Set a URL-friendly slug for your trust center. Your trust center will be accessible at a URL based on this slug. The slug must be unique across all Probo organizations.
2

Set visibility

Choose whether your trust center should be public, private (gated), or disabled.
3

Configure search engine indexing

Control whether search engines can index your trust center:
  • INDEXABLE — allows search engines to crawl and index the page
  • NOT_INDEXABLE — sends a noindex directive to search engines
If your trust center is private or contains sensitive information, set this to NOT_INDEXABLE.
4

Add content

Add compliance framework badges, files, references, and configure the mailing list to make your trust center useful for visitors.

​
Custom domain

By default your trust center is served from Probo’s domain. You can configure a custom domain (e.g. security.yourcompany.com) so the trust center reflects your brand.
1

Add your custom domain

Create a custom domain record in Probo with your desired hostname.
2

Configure your DNS

Add a CNAME record in your DNS provider pointing your hostname to Probo’s trust center endpoint. Probo will verify the CNAME record is in place before activating the domain.
3

SSL certificate provisioning

Once the CNAME is verified, Probo automatically provisions a TLS certificate via ACME (Let’s Encrypt or equivalent). The domain will be active and served over HTTPS once the certificate is issued.
DNS propagation can take up to 48 hours. SSL certificate provisioning begins automatically after your CNAME is verified.

​
NDA-gated access

For sensitive compliance documents, you can require visitors to accept a Non-Disclosure Agreement (NDA) before accessing the trust center.
1

Upload your NDA

Upload a PDF of your NDA to the trust center. This file is presented to visitors who request access.
2

Enable NDA requirement

Associate the uploaded NDA file with your trust center. Visitors will be required to accept the agreement before viewing gated content.
3

Remove the NDA

Delete the NDA file association from the trust center at any time. Existing access grants remain valid.

​
Access grants (private trust center)

When your trust center is set to PRIVATE, you control access by creating access grants for specific individuals or domains.
ActionDescription
CreateGrant access to a specific email address or organization domain
UpdateModify an existing grant (e.g. change its expiry)
DeleteRevoke access for a grantee
Access grants have states that reflect the visitor’s progress through the access flow:
StateMeaning
PendingGrant created but visitor has not yet signed in
ActiveVisitor has authenticated and has access
RevokedAccess has been explicitly removed

​
Compliance framework badges

Display your current certifications prominently on your trust center. You manage which compliance frameworks appear as badges through the compliance framework configuration. Frameworks are ranked to control their display order. You can add external URLs to each framework entry — for example, a link to a third-party certification portal or a downloadable certificate.

​
Trust center files

Upload files to share with visitors, such as:
  • Penetration test executive summaries
  • SOC 2 bridge letters
  • Security overview documents
Each file has a name, description, and an optional expiry date. You can control whether individual files are visible to the public or only to visitors with an access grant.

​
Trust center references

References are external links you surface on your trust center, such as links to your company’s security blog, bug bounty program, or certification portal. Each reference has a name, URL, and optional logo.

​
Mailing list

The trust center includes an opt-in mailing list for security update notifications. Visitors can subscribe to receive notifications when you publish a security update.

​
Managing subscribers

Subscribers are stored in your trust center mailing list. You can:
  • View all subscribers
  • Add subscribers manually
  • Remove individual subscribers

​
Publishing security updates

Create a mailing list update with a subject and body, then send it to all active subscribers. Updates are delivered as email notifications to every subscriber.
Yes. For each vendor in your vendor registry, you can enable show_on_trust_center. When enabled, the vendor’s name and certifications are displayed in the subprocessors section of your trust center.
Yes. Documents with trust_center_visibility set to PUBLIC or PRIVATE are listed on your trust center. Visitors with appropriate access can request to view them. Document access requests go through an approval workflow where you can grant, reject, or revoke access.
Setting visibility to NONE makes the trust center inaccessible to all external visitors. Existing access grants, subscribers, and content are preserved. You can re-enable the trust center at any time.
