The short version

  • Each has a real cost: Nessus nessus Professional is $4,790 for one year, with no free or low cost commercial tier; Transcend value is proportional to integration coverage, so every bespoke internal service needs a connector that your engineers build and then maintain, and the automation promise degrades quietly each time an internal API changes and nobody updates the connector.
  • They diverge on capability: Nessus covers Vulnerability scanning, Transcend covers Data subject request automation.
  • Prices and features above were last checked on 31 August 2026.

Transcend

  • A consumer app processing millions of user records that has to delete a user across a warehouse, a CRM, a support desk and three internal services within a statutory deadlinenot Nessus
  • A privacy team that currently fulfils requests by emailing system owners and wants machine evidence that deletion actually occurrednot Nessus
  • A company wiring consent signals through to advertising and analytics platforms so refused consent is honoured downstream rather than only at the bannernot Nessus

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Nessus

  • Nessus Professional is $4,790 for one year, with no free or low cost commercial tier
  • Multi year terms are the only discount route, at $9,330.95 for two years and $13,637.54 for three
  • It is a single user scanner, so team workflows mean migrating to another Tenable product
  • Tenable One vulnerability management is priced separately, starting at $3,500 a year for 100 assets

Transcend

  • Value is proportional to integration coverage, so every bespoke internal service needs a connector that your engineers build and then maintain, and the automation promise degrades quietly each time an internal API changes and nobody updates the connector.
  • Pricing is quoted and scales with data volume and integration count, so the cost grows precisely as the company grows, and there is no public anchor to negotiate against at renewal.
  • It is deep on fulfilment and consent but thinner than OneTrust on wider governance, third party risk and ethics programme management, so a large enterprise privacy office may end up running two vendors.
  • Deployment requires engineering time to install and authorise integrations into production data stores, which means the privacy team cannot buy and implement it alone and the project competes with engineering roadmap.
  • Automated deletion against production systems is a destructive operation, so organisations without good staging environments and confident data ownership move slowly and often run the tool in advisory mode for months before letting it execute.

Answered from the vendors’ own pages

Nessus: What is the cheapest Nessus option?

Transcend: How is Transcend different from a subject request ticketing tool?

It executes the request against your systems through integrations rather than routing a task to a person. That is the whole product, and it is why the deployment requires engineering involvement.

Nessus: What is the difference between Nessus Professional and Expert?

Nessus Expert costs $6,790 per year for a 1-year license (compared to $4,790 for Professional) and includes enhanced capabilities. Multi-year rates are available at discounted prices.

Source
Transcend: What does it cost?

Nothing is published. Reported deals begin around 10,000 US dollars a year and rise with data volume, integration count and modules such as AI governance.

Nessus: Does Nessus offer optional support or training?

Yes, Nessus offers add-on services: Advanced Support at $400/year provides 24x365 access to phone, email, community, and chat support. On-Demand Training costs $275/year for Fundamentals course access or $385/year for both Fundamentals and Advanced courses.

Source
Transcend: Can it replace OneTrust?

For subject rights, consent and data mapping, often yes. For third party risk, ethics reporting and wider GRC programme management it is narrower.

Transcend: Does it handle unregistered systems?

It scans for personal data silos rather than relying solely on a declared inventory, which routinely surfaces systems the privacy register did not contain.
