The short version

  • Only Tenable Nessus has a free tier, so it costs nothing to try first.
  • Each has a real cost: Tenable Nessus nessus Professional is $4,790 for one year, sold as an annual licence rather than a per scan or usage based fee; 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: Tenable Nessus covers Network scanning, Transcend covers Data subject request automation.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Tenable Nessus

  • Nessus Professional is $4,790 for one year, sold as an annual licence rather than a per scan or usage based fee
  • Support beyond the base entitlement costs an extra $400 per year for Advanced Support with 24x365 phone and chat access
  • The on demand training course is a separate $275 purchase for a single person for one year
  • Multi year discounts require paying for two or three years up front

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

Tenable Nessus: What are the three Nessus offerings?

Nessus Essentials is a free introductory offering for educators, students, and career starters, limited to 16 IPs for scanning. Nessus Professional is designed for consultants and SMBs, providing unlimited IT scans across any location. Nessus Expert is the premium offering extending Professional with web application scanning, infrastructure-as-code scanning, and external attack surface assessment up to 5 domains.

Source
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.

Tenable Nessus: What OS platforms does Nessus support?

Nessus runs on Debian/Kali Linux, Fedora, FreeBSD, Mac OS X, Red Hat/CentOS, SUSE Linux, Ubuntu, and various Windows versions including Server 2008, 2012, and Windows 7-10.

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.

Tenable Nessus: Can I use Nessus to scan third-party networks as a consultant?

Yes, Tenable permits you to use Nessus to scan third-party networks. Nessus Professional is ideal for consultants.

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.

Tenable Nessus: Can Nessus perform PCI external scanning?

Yes, you can use Nessus Professional to perform external network scans as required by the PCI DSS 11.2.2 requirement.

Source
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.

Tenable Nessus: What additional features does Nessus Expert provide?

Web application scanning, which is dynamic application security testing (DAST) providing comprehensive visibility and insight into web application security issues; scanning code repositories for vulnerabilities; and assessing external attack surface with subdomain discovery.

Source
Tenable Nessus: What support options exist for Nessus Professional?

Standard Support includes software upgrades, patches, plugin access, and 24x7 support via chat and community portal. Advanced Support adds 24x7 phone access and committed SLAs: P1 less than 2 hours, P2 less than 4 hours, P3 less than 12 hours, P4 less than 24 hours.

Source
Tenable Nessus: How frequently are Nessus plugins updated?

Nessus plugins are updated daily, based on when vendors and security research sites publish new vulnerabilities.

Source
Tenable Nessus: How does licensing work in virtual machine environments?

Whether you are using Nessus in a physical or a virtual environment, the IP addresses or hosts that you are scanning from must be licensed.
